Protokol
LEGAL

Terms of Use

Effective September 16, 2026

These Terms of Use ("Terms") are an agreement between you and Cisco & LeChau LLC, a California limited liability company that operates Protokol ("Protokol," "we," "us"). They apply to the Protokol iOS app, protokolapp.com, Protokol AI and any related services (together, the "Services"). By creating an account or using the Services, you agree to these Terms and to our Privacy Policy at protokolapp.com/privacy.

Please read section 16. It requires most disputes to be resolved by individual arbitration instead of in court, and it waives class actions. You can opt out within 30 days of first accepting these Terms.

1. Who can use Protokol

You must be at least 18 years old and able to form a binding contract to use the Services. By using them, you confirm that you are. You are responsible for making sure your use of the Services follows the laws that apply to you.

2. Protokol is not medical advice

Protokol is an educational reference and a personal record-keeping tool. It is not a medical device and it does not provide medical advice, diagnosis or treatment.

  • Protokol does not calculate, recommend or suggest doses, amounts or schedules. Every amount and schedule in the app is entered by you, and you are solely responsible for it.
  • Library content summarizes published research and regulatory information for general education. It may be incomplete, may not reflect the latest research, and is not tailored to you.
  • Some compounds described in the library are not approved by the U.S. Food and Drug Administration for human use. Their inclusion is not an endorsement, and it is not a suggestion that you obtain or use them.
  • Always talk to a licensed physician before starting, changing or stopping anything that affects your health, and never ignore or delay professional medical advice because of something you read in Protokol.
  • If you think you are having a medical emergency, call 911 or your local emergency number right away.

3. Protokol AI

Protokol AI is an AI research assistant. It cites sources where it can, and it will not discuss doses, amounts or schedules. AI output can be wrong, incomplete or out of date, even when it cites a source. Check anything important against the original source and a qualified professional. Do not rely on Protokol AI for medical decisions. You agree not to use Protokol AI to create content that is unlawful or harmful, or to try to get around its safeguards.

4. Your account

You can sign in with Apple, Google or email, or use the app without an email address. Please give accurate information and keep your sign-in secure. You are responsible for activity on your account.

If you use the app without an email address, your account is tied to your device. If you lose or reset the device, we may not be able to recover your data.

You can delete your account at any time in the app's settings. Deletion is permanent and cannot be undone.

5. Subscriptions and payments

Protokol offers a free plan with limited features, and paid plans that unlock premium features. At the time of these Terms, paid plans are:

  • Monthly: $9.99 per month.
  • Annual: $69.99 per year, with a 3-day free trial for eligible new subscribers.
  • Lifetime: $99.99, paid once.

Prices are in U.S. dollars, may vary by country and may change. The price that applies to you is the one shown in the App Store before you confirm your purchase.

  • Billing: purchases are made and billed through your Apple account and are subject to Apple's terms. We do not process payments.
  • Auto-renewal: monthly and annual subscriptions renew automatically at the end of each period, and your Apple account is charged, unless you turn off auto-renew at least 24 hours before the current period ends.
  • Free trials: if you start a free trial, your subscription begins and you are charged when the trial ends unless you cancel at least 24 hours before it ends. Any unused part of a trial ends if you buy a subscription.
  • Cancelling: manage or cancel in your iPhone's Settings under your name, then Subscriptions. After you cancel, you keep access until the end of the period you paid for. Deleting the app or your Protokol account does not cancel a subscription.
  • Refunds: refunds are handled by Apple under its policies. You can request one at reportaproblem.apple.com.
  • Lifetime access: a lifetime purchase gives you premium features for as long as we operate Protokol, not for any particular length of time.
  • Price changes: if a subscription price goes up, you will be told in advance as Apple requires, and you can cancel before the new price applies.
  • Codes: promo and partner codes have no cash value, cannot be resold, may expire, and may be withdrawn if misused.

We may change which features are included in each plan. If we remove a major paid feature, we will try to give you notice in the app.

6. Your content

You own the information, logs, notes and photos you add to Protokol ("Your Content"). You give us a limited license to host, store, process, back up and display Your Content only as needed to run the Services for you, including sending your questions to our AI provider when you use Protokol AI. This license ends when you delete Your Content or your account, except for copies in backups that roll off on their normal schedule.

You are responsible for Your Content and confirm you have the right to upload it. Do not upload photos of other people without their permission.

If you send us feedback or ideas, we may use them without any obligation to you.

7. Acceptable use

You agree not to:

  • Use the Services for anything illegal, including buying, selling or distributing substances in violation of law.
  • Copy, sell, or redistribute the library, app content or AI output as your own product.
  • Scrape, reverse engineer, decompile or try to extract the source code of the Services, except where the law allows it.
  • Interfere with, overload or try to gain unauthorized access to the Services, other accounts or our systems.
  • Use bots or automated means to access the Services or Protokol AI.
  • Misrepresent your identity or impersonate anyone.
  • Use the Services to harm, harass or mislead others.

8. Third-party services, links and partners

The Services work with, and link to, services we do not control, such as Apple, Google and partner websites. Your use of those services is governed by their own terms and privacy policies.

Protokol may feature partner brands. We may earn a commission or other compensation when you use a partner link or code. Partners are independent businesses. We do not manufacture, sell, test or verify their products, and a partnership is not a medical recommendation. Any purchase you make from a partner is between you and that partner, and you are responsible for making sure it is lawful where you live.

9. Our intellectual property

The Services, including the app, website, library content, design, software, and the Protokol name and logo, belong to us or our licensors and are protected by law. We give you a personal, non-exclusive, non-transferable, revocable license to use the app on Apple devices you own or control, for your own non-commercial use, in line with these Terms and Apple's Usage Rules. We reserve all rights not expressly granted.

10. Apple App Store terms

If you downloaded the app from the Apple App Store, you and we agree that:

  • These Terms are between you and us only, not Apple. We, not Apple, are responsible for the app and its content.
  • Apple has no obligation to provide maintenance or support for the app.
  • If the app fails to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price of the app, if any. To the maximum extent permitted by law, Apple has no other warranty obligation for the app.
  • Apple is not responsible for addressing any claims by you or a third party relating to the app, including product liability claims, claims that the app fails to meet legal or regulatory requirements, and consumer protection or privacy claims.
  • If a third party claims that the app or your use of it infringes their intellectual property rights, we, not Apple, are responsible for the investigation, defense, settlement and discharge of that claim.
  • You confirm that you are not located in a country subject to a U.S. government embargo or designated as a "terrorist supporting" country, and that you are not on any U.S. government list of prohibited or restricted parties.
  • Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

11. Suspension and termination

You can stop using the Services and delete your account at any time. We may suspend or end your access if you break these Terms, if required by law, or if your use creates risk or harm for us or others. We may also change, suspend or discontinue all or part of the Services. Sections that by their nature should survive termination will survive, including sections 2, 6, 9 and 12 through 18.

12. Disclaimers

THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE." TO THE FULLEST EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT AND ACCURACY. WE DO NOT PROMISE THAT THE SERVICES, LIBRARY CONTENT OR AI OUTPUT WILL BE ACCURATE, COMPLETE, UNINTERRUPTED, SECURE OR ERROR-FREE, OR THAT REMINDERS WILL ALWAYS BE DELIVERED. YOU USE THE SERVICES, AND MAKE ANY HEALTH DECISIONS, AT YOUR OWN RISK.

13. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, PROTOKOL AND ITS MEMBERS, MANAGERS, EMPLOYEES AND AGENTS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, PROFITS OR GOODWILL, OR FOR ANY PERSONAL INJURY OR HEALTH OUTCOME ARISING FROM YOUR USE OF ANY SUBSTANCE OR YOUR RELIANCE ON THE SERVICES, EVEN IF WE WERE TOLD SUCH DAMAGES WERE POSSIBLE.

TO THE FULLEST EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICES IS LIMITED TO THE GREATER OF THE AMOUNT YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM AROSE OR $50.

Some jurisdictions do not allow certain disclaimers or limits, so some of the above may not apply to you. Nothing in these Terms limits liability that cannot be limited by law.

14. Indemnity

To the extent permitted by law, you agree to defend and indemnify Protokol and its members, managers, employees and agents against claims, losses and expenses, including reasonable legal fees, arising from your violation of these Terms, your misuse of the Services, or Your Content.

15. Governing law

These Terms are governed by the laws of the State of California, without regard to its conflict of laws rules, except that the Federal Arbitration Act governs section 16. Subject to section 16, any dispute that is not arbitrated will be brought only in the state or federal courts located in Los Angeles County, California, and you and we consent to their jurisdiction.

16. Dispute resolution and arbitration

Try to resolve it with us first

Before starting a formal claim, you agree to email support@protokolapp.net with a description of the dispute and what you are asking for. We will try in good faith to resolve it within 60 days.

Binding individual arbitration

If we cannot resolve it, you and we agree that any dispute relating to these Terms or the Services will be resolved by binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules. The arbitration may be held by video, by phone, or in person in the county where you live or in Los Angeles County. We will pay filing and arbitrator fees as the AAA Consumer Rules require. The arbitrator may award the same individual relief a court could.

Exceptions

Either of us may bring an individual claim in small claims court, and either of us may ask a court for an injunction to stop infringement or misuse of intellectual property.

Class action waiver

You and we agree to bring claims only in an individual capacity, not as a plaintiff or class member in any class, collective or representative proceeding. If this waiver is found unenforceable for a claim, that claim will be decided in court, not arbitration.

Your right to opt out

You can opt out of this arbitration agreement by emailing support@protokolapp.net within 30 days of first accepting these Terms, with the subject line "Arbitration Opt-Out" and your name and account email. Opting out does not affect any other part of these Terms.

17. Changes to these Terms

We may update these Terms. When we do, we will change the effective date at the top, and for material changes we will give notice in the app or by email before they take effect. If you keep using the Services after changes take effect, you accept the updated Terms. Changes will not apply to disputes that arose before they took effect.

18. General

These Terms and our Privacy Policy are the entire agreement between you and us about the Services. If any part is found unenforceable, the rest stays in effect. Our failure to enforce a provision is not a waiver. You may not transfer these Terms without our consent; we may transfer them as part of a merger, acquisition or sale of assets. Notices to you may be given in the app or by email.
