ARC — Terms of Use

ARC Collaboration LLC

Effective date: 1 November 2026 — Last updated: 1 November 2026

1. Agreement to these Terms

These Terms of Use (the “Terms”) govern your access to and use of the ARC platform at arcollaboration.com (the “Platform”), operated by ARC Collaboration LLC, a Wyoming limited liability company with its principal place of business at 30 N Gould St Ste R, Sheridan, WY 82801 (“ARC,” “we,” “us,” “our”).

By accessing or using the Platform, creating an account, or purchasing a membership, you agree to these Terms, the ARC Privacy Policy, and the ARC Platform Disclaimer, each incorporated by reference. If you do not agree, do not use the Platform.

2. Eligibility

You must be at least eighteen (18) years old to use the Platform and to create an account. By using the Platform you represent that you are eighteen or older, that you have the legal capacity to enter into this agreement, and that the information you provide is accurate.

3. The Platform — research and informational purpose

ARC is an independent research documentation and verification platform providing subscription-based access to research and educational content for independent researchers working with peptides, amino acids, small molecules, and related research compounds.

ARC publishes structured, evidence-referenced documentation of the published literature. All content is provided exclusively for independent research and informational purposes and does not constitute medical, clinical, legal, or professional advice, as detailed in the ARC Platform Disclaimer.

ARC is not an e-commerce platform. ARC does not manufacture, sell, supply, handle, distribute, broker, or arrange the acquisition of any compound, and holds no commercial interest in any compound it documents. Its Operating Agreement prohibits its members from holding such an interest. Nothing on the Platform is an offer to sell or a solicitation of an offer to buy any compound or product.

ARC operates independently and as a principal. ARC has no partners, affiliates, resellers, or referral arrangements, and no third party acts for ARC or on ARC’s behalf in relation to the Platform.

Reading, accessing, or using ARC content creates no professional relationship of any kind between ARC and you.

4. Accounts

4.1 You are responsible for the accuracy of your account information, for safeguarding your credentials, and for all activity under your account. Notify ARC promptly at info@arcollaboration.com of any unauthorized use.

4.2 Memberships are personal to you. They may not be shared, transferred, resold, or used by more than one individual. Credential sharing is grounds for termination without refund.

4.3 ARC may suspend or terminate any account that violates these Terms.

5. Membership, fees, billing, and renewal

5.1 What membership provides

ARC offers one membership, available on two billing plans — monthly and annual. Both plans provide the same access:

gated content across all Research Areas, Research Modules, and Compound Deep Dives;
gated content within Research Fundamentals, including modules, the Practical Guidance Series, the Blend Series, and quick reference sheets, and the ARCulator calculation tool;
content within the Research Library across its seven desks — From ARC, Attributed, Publication Summaries, Regulatory & Institutional, Research Practices, The Wire, and Trends & Landscape;
the ARC Research Readiness Assessment;
third-party identity verification following successful completion of the Assessment;
issuance of a Verified Independent Researcher badge identifier and unique VIR number upon satisfaction of all three verification components in §8; and
while your membership is active, ARC’s confirmation of your VIR status in response to a verification check you initiate, as described in §8.7.

The plans differ only in billing frequency and price. Neither plan restricts access to any part of the Platform, the Research Readiness Assessment, identity verification, or the Verified Independent Researcher designation.

What membership is. Membership provides access to ARC’s research library as it exists from time to time. ARC documents a moving literature: documentation is added, revised, corrected, superseded, and withdrawn on an ongoing basis, and compounds, documents, and features may be removed at ARC’s editorial discretion or where circumstances outside ARC’s control require it. Membership is access to an evolving library, not to any specific document, compound, or feature. No particular content is guaranteed to be available at any time or for any period, and changes to the library do not entitle you to a refund, credit, or extension of your term.

5.2 Plans and fees

Plan	Fee	Billing period
Monthly	US $7.99 per month	One (1) month, recurring
Annual	US $79.00 per year	Twelve (12) months, recurring

Fees are exclusive of applicable taxes. The plan you select, its fee, its billing period, and the fact that it renews automatically are disclosed to you before you provide payment information and again on your receipt.

ARC may change the fee for future terms on notice under §5.5.

5.3 Automatic renewal

Your membership renews automatically. Unless you cancel before the end of your current term, your membership renews for a further period equal to the billing period of the plan you selected — one (1) month on the monthly plan, twelve (12) months on the annual plan — and the payment method on file will be charged the then-current fee for that plan automatically, without further action by you.

You provide express affirmative consent to this recurring charge at checkout, separately from your general assent to these Terms.

You may cancel at any time. Cancellation is available online through your account portal, in the same medium and with no more steps than enrollment required, without contacting an agent and without passing through any retention offer. Cancellation takes effect at the end of the current paid term — the end of the current month on the monthly plan, the end of the current year on the annual plan — and you retain access until then.

5.4 Renewal notice

Annual plan. ARC will notify you of each upcoming renewal — stating the renewal date, the amount, and how to cancel — not less than thirty (30) days and not more than forty-five (45) days before the renewal date, to the email address on your account.

Monthly plan. Because the billing period is one month, advance notice of each renewal is not practicable and ARC does not send one. Instead, ARC sends a receipt to the email address on your account after each monthly charge, stating the amount charged, the date of the next scheduled charge, and how to cancel. You may cancel at any time before that date under §5.3. In addition, once in each twelve-month period ARC will send you a reminder, to the email address on your account, stating that your membership renews automatically, the monthly amount charged, and how to cancel.

Both plans. Each renewal notice and each monthly receipt will identify the version of these Terms then in force and invite you to review them. Renewal of your membership constitutes your reaffirmation of these Terms as they stand at the renewal date.

5.5 Fee changes

ARC will notify you of any change to your fee not less than seven (7) days and not more than thirty (30) days before the change takes effect, by email to the address on your account. The notice will state the new amount, the date of the first charge at that amount, and how to cancel. You may cancel before the new fee takes effect if you do not accept it.

5.6 Refunds

Initial term. You may request a full refund of your first payment on either plan within fourteen (14) days of that purchase. Refunds are made to the original payment method. After that window the payment is non-refundable; access to documentation is granted immediately on purchase and cannot be returned.

Forfeiting the refund by taking the Assessment. The Research Readiness Assessment and its question bank are confidential and proprietary (§8.4). Once you have sat the Assessment you have received that material, and it cannot be returned. Where you achieve a passing score, ARC also incurs the cost of third-party identity verification and issues a permanent verification record. If you choose to sit the Assessment while you are still inside the fourteen-day window, you give up your right to a refund of that term, whether or not you achieve a passing score.

You will not encounter this by accident. Before the Assessment begins, and only while you are inside the refund window, ARC will display a notice stating in plain terms that proceeding ends your refund eligibility whether or not you achieve a passing score, and will require you to affirmatively acknowledge it. You may decline and return at any point; the Assessment remains available for the whole of your term. Your acknowledgment is recorded with a timestamp. If you do not sit the Assessment inside the window, your refund right is unaffected.

Renewal terms. Renewal fees are non-refundable on either plan, and partial periods are not refunded. On the annual plan, the renewal notice under §5.4 exists to give you the opportunity to cancel before being charged. On the monthly plan, you may cancel at any time, which stops the next charge.

Exceptions. ARC will refund charges arising from its own billing error, duplicate charges, and fraudulent or unauthorized charges. ARC may issue discretionary refunds in other circumstances without creating any obligation to do so again. Nothing in this section limits any non-waivable right you have under the law of your state.

5.7 Payment processing

Payment is processed by third-party payment processors. ARC does not receive or store full payment card details. You authorize ARC and its processors to charge your payment method for all amounts due. Your use of payment services is subject to the processor’s own terms.

5.8 Failed payments

If a charge fails, ARC will notify you at the email address on your account and will retry the charge over a grace period of ten (10) days. Your membership and your VIR status remain active during that grace period, and a payment that succeeds within it is treated as having been made on time, so no lapse is recorded.

If payment has not succeeded by the end of the grace period, ARC may suspend access and treat the membership as lapsed. You remain responsible for amounts properly owed.

5.9 Changing your plan

You may change between the monthly and the annual plan at any time through your account portal.

Monthly to annual. The change takes effect immediately. You are charged the annual fee at that point, and the unused balance of your current monthly period is credited against it. Your renewal date becomes twelve (12) months from the date of the change.
Annual to monthly. The change takes effect at the end of your current annual term. You keep full access until then, and the annual fee already paid is not refunded. Monthly billing begins on the day after your annual term ends.

Changing plans does not affect your VIR status, your verification record, or your original verification date, and it does not interrupt active status or start a new period of inactivity.

5.10 Chargebacks

If you dispute a charge, contact info@arcollaboration.com first; initiating a chargeback without contacting us may result in suspension pending resolution.

6. Acceptable use

You may not:

use the Platform for any unlawful purpose;
copy, reproduce, scrape, crawl, harvest, systematically download, redistribute, resell, or create derivative works from ARC content except as expressly permitted;
use ARC content to train, fine-tune, or develop any machine learning or artificial intelligence model, or to build any competing or derivative product or dataset;
share account access, or circumvent, disable, or interfere with access controls, paywalls, authentication, or security features;
reverse engineer, decompile, or attempt to derive the source of the Platform or the ARCulator;
misrepresent your identity, your VIR status, or your relationship to ARC;
use the Platform to promote, market, advertise, or facilitate the sale, supply, or acquisition of any compound;
upload malicious code or interfere with the operation or integrity of the Platform; or
use the Platform in violation of applicable law, including export control and sanctions law.

ARC content is licensed to you for your own independent research and informational use only, and not for redistribution.

7. Intellectual property

7.1 The Platform and all content — including Research Areas, Research Modules, Compound Deep Dives, Research Fundamentals, the Practical Guidance Series, the Blend Series, Research Library articles, the Research Readiness Assessment and its question bank, figures, design, typography, the ARC brand and logo, and the research framework — are owned by ARC or its licensors and protected by law. “ARC,” “ARCulator,” “Verified Independent Researcher,” and “VIR” are marks of ARC.

7.2 Subject to these Terms and payment of the fee, ARC grants you a limited, personal, non-exclusive, non-transferable, revocable license to access and view Platform content for your own independent research and reference during your membership. You may make reasonable personal-use copies. No other rights are granted.

The Platform may cache content on your device for offline access. Cached content remains subject to this license, is licensed only for the duration of your membership, and must be deleted on termination as provided in §15.4.

7.3 The license does not permit republication, redistribution, commercial exploitation, incorporation into any product or service, or the creation of derivative works, except with ARC’s prior written consent.

7.4 ARC’s documentation references published scientific literature. ARC does not reproduce copyrighted source text and grants no rights in third-party works. Referenced works remain the property of their rightsholders.

7.5 Notices of claimed copyright infringement may be sent to our designated agent at Registered Agents Inc., 30 N Gould St Suite R, Sheridan, WY 82801, info@arcollaboration.com. We may terminate the accounts of repeat infringers.

7.6 If you send us suggestions or feedback, we may use them without restriction or obligation to you.

8. The Research Readiness Assessment and Verified Independent Researcher status

8.1 The three components

The VIR designation is issued only when a member completes three independent components:

identity confirmation by a legally authorized, recognized, independent third-party identity verification provider;
content pathway engagement, as recorded by the Platform; and
a passing score on the ARC Research Readiness Assessment.

All three are required. None is sufficient alone.

8.2 What the designation attests

The designation attests to three facts, and only these: that your identity has been confirmed by an independent verification provider; that you have accessed and engaged with ARC’s defined research content pathways; and that you achieved a passing score on the Assessment — each as of a documented date.

8.3 What it is not

The VIR designation is an achievement, not a permission. It is not a license, permit, certification, professional credential, or qualification, and it is not authorization to acquire, possess, handle, or administer any compound. There is no legal reference under which such a license could exist, and ARC neither issues nor is authorized to issue one. You agree not to represent the designation as anything more than §8.2 states.

8.4 Proprietary assessment

The Research Readiness Assessment and its question bank are the confidential, proprietary property of ARC. You may not copy, record, reproduce, distribute, publish, or share any assessment question or answer, in whole or in part; sit the Assessment for another person or permit another person to sit it for you; or use unauthorized assistance. Breach is a material breach of these Terms, voids the result, and may result in termination and loss of status without refund.

8.5 No guarantee; retakes

ARC does not guarantee that you will achieve a passing score or attain VIR status. A passing result on one occasion does not guarantee a passing result on any future occasion. If you do not achieve a passing score you may retake the Assessment after the cooldown period applied by ARC, currently forty-eight (48) hours between attempts. Retaking the Assessment carries no further consequence for refund eligibility; the forfeiture under §5.6 arises on your first sitting.

8.6 Active status, dormancy, reactivation, and the five-year limit

The verification record is permanent. That your identity was confirmed and your knowledge demonstrated, as of a documented date, is a fact ARC records and does not withdraw. ARC maintains that record as immutable and timestamped.

Active status requires an active membership. What membership provides is ARC’s ongoing confirmation of your status to others, and continuing access to an evolving body of research content. If your membership lapses, your status becomes inactive. Your underlying verification record and original verification date are unaffected.

A failed payment does not immediately make your status inactive. The ten-day grace period in §5.8 applies, and a payment that succeeds within it records no lapse. Changing between the monthly and annual plans under §5.9 does not affect your status, your record, or your dates.

Reactivation. You may reactivate inactive status at any time within five (5) years of your Assessment passing date or your last active date, whichever is later, by renewing your membership. Reactivation runs against your original verification record and date. No re-assessment is required.

After five years. If your status has been inactive beyond that period, reactivation requires that you complete the Research Readiness Assessment again. The research literature ARC documents changes over time, and knowledge demonstrated against an earlier body of material is not demonstrated against the current one. Your original verification record and date remain permanent and are not erased by re-assessment.

Suspension and revocation. ARC may suspend or revoke status for breach of these Terms, for misrepresentation or fraud in obtaining the designation, for misuse of the badge, or where the underlying identity verification is withdrawn or invalidated in a manner that calls into question the accuracy of the original verification.

Administrative closure or termination of your account by the identity verification provider, for reasons unrelated to the accuracy of that verification, does not affect a designation already issued. The provider is independent of ARC and may close accounts under its own terms; a verification that occurred is a fact that does not cease to be true because the provider later closes the account.

Except where immediate action is necessary, ARC will give notice and a reasonable opportunity to respond. ARC alone determines status.

8.7 Verification checks

If you choose to present or enter your ARC badge identifier with a third party and initiate a verification check, you authorize ARC to confirm to that party only whether your status is active or inactive and, if active, your membership end date. On the monthly plan, that date is the end of your current monthly period; because the plan renews automatically, it is the date through which your status is currently confirmed rather than a date on which your membership is expected to end. ARC discloses no other information through a verification check.

A verification check occurs only as a result of your own action in presenting your badge identifier and initiating it. ARC determines status independently; no third party’s input changes your status.

No relationship is created by a verification check. A third party that queries ARC is not a partner, agent, affiliate, or licensee of ARC. ARC makes no representation or warranty to any such party, owes no duty to any party relying on a verification result, and accepts no liability for any decision any party makes on the basis of one. ARC does not monitor, supervise, or vouch for the conduct of any VIR holder.

8.8 Use of the badge

You may display your badge identifier truthfully, in the form ARC issues, and only in connection with your own designation. You may not alter it, use it to imply licensure, approval, endorsement, professional qualification, or regulatory standing, use it to promote or sell any compound or product, or use it in any way that misstates what it attests.

8.9 Unavailability of the identity verification pathway

Identity verification is performed by an independent third-party provider. That provider may cease providing services, change its terms, or become unavailable to ARC, and ARC does not control it.

If the identity verification pathway becomes unavailable, ARC will use reasonable efforts to appoint an alternative provider meeting equivalent verification standards, at no additional cost to members. ARC will notify affected members within fifteen (15) business days of the pathway becoming unavailable, stating what has happened and what ARC intends to do.

If the pathway remains unavailable for more than ninety (90) days and you have not yet been issued a VIR number, you may elect either to:

continue your membership, retaining full access to all other benefits, and retain this election until the pathway is restored; or
terminate your membership and receive a refund. On the annual plan the refund is the unused pro rata portion of your fee. On the monthly plan it is the amount you paid for each complete monthly period during which the pathway was unavailable, and you may in any event simply cancel at any time under §5.3.

Members who have already been issued a VIR number are unaffected. A designation already issued, and the verification record supporting it, are permanent and do not depend on the continued availability of any provider.

8.10 Changes to the Assessment, withdrawn content, and continuity of the programme

Withdrawn content. Content withdrawn, revised, or superseded after a designation is issued does not affect that designation or the verification record supporting it. The designation attests to what was demonstrated on a documented date, against the material as it stood at that date.

Changes to the Assessment. ARC revises the Research Readiness Assessment over time. A designation issued against an earlier version remains valid, and reactivation within the five-year period under §8.6 runs against the original record without re-assessment, whether or not the Assessment has since changed. Re-assessment is required only after that period has elapsed.

Continuity. If ARC discontinues the Verified Independent Researcher programme, verification records already issued remain permanent, and ARC will continue to confirm the status of existing designations under §8.7 for as long as ARC operates the Platform. ARC will not withdraw confirmation of designations already issued.

9. Assumption of risk; researcher responsibility

You acknowledge and agree that:

9.1 Independent research with research compounds involves inherent risks.

9.2 ARC content is informational only. It does not authorize, instruct, or recommend any specific action.

9.3 You are solely responsible for determining the legal and regulatory status of any compound in your jurisdiction — federal, state, and local — for obtaining any permits, licenses, registrations, or institutional approvals required before acquiring, possessing, storing, handling, or working with any compound, for complying with all applicable law, and for monitoring regulatory change.

9.4 Many compounds documented on the Platform have not been approved by any regulatory authority for use in humans, and much of the literature ARC documents was not generated in humans. Evidence grades describe the state of the published literature only and are not statements about safety, efficacy, legality, or regulatory approval.

9.5 You will not rely on ARC content as a substitute for qualified professional guidance, and will consult a qualified professional where your circumstances warrant it.

9.6 You assume all risk arising from any research activity you undertake. ARC has no supervision over, involvement in, visibility into, or control over your activities, and no responsibility or liability for any action you take informed by or in connection with ARC content.

9.7 Holding VIR status does not reduce, satisfy, transfer, or substitute for any responsibility in this section.

10. Content, changes, and availability

10.1 ARC documents a moving literature. Content is revised, corrected, superseded, and withdrawn. ARC makes no commitment that any particular content will remain available, and content available at purchase may change during your term.

10.2 ARC may add to, revise, or discontinue content and features at any time. Because membership is access to an evolving library rather than to specific content (§5.1), such changes do not entitle you to a refund, credit, or extension of your term. This applies whether a change is made at ARC’s editorial discretion or is required by law, regulatory action, court order, or a third-party legal demand.

10.2.1 Section 10.2 does not apply to the identity verification pathway, which is governed by §8.9. If ARC ceases to operate the Platform entirely, ARC will refund the unused pro rata portion of your fee.

10.3 ARC does not warrant uninterrupted or error-free availability.

11. The ARCulator and other tools

The ARCulator is a calculation aid. It performs arithmetic on values you supply. It does not validate your inputs, does not know your circumstances, and does not recommend anything. Outputs are only as sound as the inputs and the assumptions behind them. You are responsible for verifying every result independently before relying on it. ARC makes no warranty as to the accuracy, completeness, or fitness of any output.

12. Disclaimers

12.1 THE PLATFORM AND ALL CONTENT ARE PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTY OF ANY KIND. TO THE FULLEST EXTENT PERMITTED BY LAW, ARC DISCLAIMS ALL WARRANTIES, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, TITLE, AND NON-INFRINGEMENT.

12.2 ARC DOES NOT WARRANT THAT CONTENT IS ACCURATE, COMPLETE, CURRENT, OR FREE OF ERROR. ARC DOCUMENTS PUBLISHED LITERATURE, WHICH IS ITSELF INCOMPLETE, INCONSISTENT, AND SUBJECT TO REVISION AND RETRACTION.

12.3 NO CONTENT IS MEDICAL, CLINICAL, LEGAL, REGULATORY, OR OTHER PROFESSIONAL ADVICE.

12.4 ARC MAKES NO REPRESENTATION AS TO THE LEGALITY OF ANY COMPOUND IN ANY JURISDICTION, OR AS TO THE IDENTITY, PURITY, QUALITY, OR SAFETY OF ANY MATERIAL FROM ANY SOURCE.

12.5 The full disclaimer in the ARC Platform Disclaimer applies. Some jurisdictions do not allow the exclusion of certain warranties; where that is so, these exclusions apply to the fullest extent permitted. The exclusions in this section are subject to §13.5.

13. Limitation of liability

13.1 TO THE FULLEST EXTENT PERMITTED BY LAW, ARC AND ITS MEMBERS, MANAGERS, OFFICERS, EMPLOYEES, CONTRACTORS, REVIEWERS, AND AGENTS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST DATA, BUSINESS INTERRUPTION, OR LOSS OF GOODWILL, ARISING FROM OR RELATING TO THE PLATFORM OR THESE TERMS, ON ANY LEGAL THEORY, EVEN IF ADVISED OF THE POSSIBILITY.

13.2 TO THE FULLEST EXTENT PERMITTED BY LAW, ARC’S TOTAL AGGREGATE LIABILITY ARISING FROM OR RELATING TO THE PLATFORM OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID ARC IN THE TWELVE MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED US DOLLARS ($100).

13.3 WITHOUT LIMITING THE FOREGOING, ARC IS NOT LIABLE FOR ANY INJURY, ILLNESS, LOSS, OR DAMAGE ARISING FROM YOUR ACQUISITION, POSSESSION, HANDLING, OR USE OF ANY COMPOUND, OR FROM ANY RESEARCH YOU CONDUCT, WHETHER OR NOT INFORMED BY PLATFORM CONTENT.

13.4 These limitations apply even if a limited remedy fails of its essential purpose and are a fundamental basis of the bargain between us.

13.5 What is not limited. Nothing in §§12 or 13 excludes or limits ARC’s liability for fraud or fraudulent misrepresentation, for gross negligence, for willful or wanton misconduct, for death or personal injury caused by ARC’s negligence, or for any other liability that cannot lawfully be excluded or limited. Wyoming law does not permit a party to disclaim liability for willful or wanton misconduct, and these Terms do not attempt to.

13.6 Some jurisdictions do not allow the limitation or exclusion of certain liability. Where that is so, these limits apply to the fullest extent permitted.

14. Indemnification

You will indemnify, defend, and hold harmless ARC and its members, managers, officers, employees, contractors, reviewers, and agents from and against any claim, demand, proceeding, loss, liability, damage, cost, or expense (including reasonable attorneys’ fees) arising from or relating to: your use of the Platform; your breach of these Terms; your research activities or handling of any compound; your acquisition, possession, or transfer of any compound; your display, use, or representation of the VIR designation; your violation of any law or of the rights of any third party; or any reliance by a third party on any representation you make about your VIR status.

This indemnity does not apply to any claim to the extent it arises from ARC’s own negligence, gross negligence, willful misconduct, fraud, or breach of these Terms. ARC will notify you promptly of any claim for which it seeks indemnity, will not settle any such claim without your consent (not to be unreasonably withheld), and will give you reasonable cooperation in the defense.

15. Term, suspension, and termination

15.1 You may cancel at any time under §5.3. Cancellation ends renewal; access continues to the end of the paid term.

15.2 ARC may suspend or terminate your access immediately for breach of these Terms, for conduct ARC reasonably determines to be harmful to the Platform or other users, or as required by law. Termination for breach does not entitle you to a refund.

15.3 ARC may terminate without cause on notice, refunding the unused pro rata portion of your fee.

15.4 On termination your license under §7.2 ends and access to gated content ceases. You must delete any locally cached or offline copies of gated content held on your devices, including content cached by the Platform’s offline functionality; ARC may clear cached content on termination. Sections 3, 7, 8.2–8.3, 8.6, 8.10, 9, 12, 13, 14, 16, and 17 survive.

16. Governing law and dispute resolution

16.1 These Terms are governed by the laws of the State of Wyoming, without regard to conflict-of-laws principles.

16.2 Any dispute arising out of or relating to these Terms or the Platform will be resolved in the state or federal courts located in Sheridan County, Wyoming, and you consent to their jurisdiction, except as otherwise required by applicable law.

16.3 Before commencing any proceeding, you agree to contact ARC at info@arcollaboration.com with a written description of the dispute and to attempt resolution in good faith for sixty (60) days.

16.4 Any claim must be brought within one (1) year of accrual, or it is permanently barred, except where a longer period is required by non-waivable law.

17. General

17.1 Changes to these Terms. ARC may amend these Terms. Material changes take effect thirty (30) days after we post the revised Terms and notify registered members through the Platform and by email. Continued use after that date is acceptance. If a material change takes effect mid-term and you cancel because of it, you may request a pro rata refund of the unused portion.

17.2 Relationship to other ARC documents. These Terms, with the ARC Privacy Policy and the ARC Platform Disclaimer, constitute the entire agreement between you and ARC regarding the Platform. In the event of a conflict between these Terms and the Disclaimer, these Terms govern.

17.3 Severability. If any provision is held unenforceable, it is modified to the minimum extent necessary or severed, and the remainder continues in force.

17.4 No waiver. No failure to enforce is a waiver.

17.5 Assignment. You may not assign these Terms. ARC may assign them in connection with a merger, acquisition, or sale of assets.

17.6 Force majeure. Neither party is liable for failure to perform due to causes beyond its reasonable control.

17.7 No third-party beneficiaries. These Terms create no rights in any person other than you and ARC.

17.8 Notices. ARC may give notice by email to the address on your account or by posting to the Platform. Notice by email is deemed given twenty-four (24) hours after sending, unless ARC receives notice that the address is invalid; notice by posting to the Platform is deemed given on the date of posting. You are responsible for keeping a current email address on your account. Notices to ARC go to the address in §18, and are deemed given on receipt.

17.9 Relationship of the parties. Nothing here creates a partnership, joint venture, employment, or agency relationship.

17.10 Accessibility. ARC is committed to making the Platform accessible. See the ARC Accessibility Statement, and contact info@arcollaboration.com with any accessibility difficulty or request.

17.11 Export and sanctions. You represent that you are not located in, and are not a national or resident of, any country subject to comprehensive US sanctions, and are not on any US government restricted-party list.
