Terms of Use

1. Acceptance of Terms

By installing or using the Cleyra mobile app, or by using the Cleyra website at cleyra.skin and the tools published on it, you confirm that you have read, understood, and agree to be bound by these Terms of Use. These Terms form a binding legal agreement between you and the Company. If you do not agree with these Terms, you must not use the Services.

2. What These Terms Cover

“Services” means both of the following, together:

• The App — the Cleyra mobile application, however you obtained it
• The Site — the website at cleyra.skin, including the free calculators, trackers, and articles published there, such as the Accutane Progress Tracker

Where a section below refers to “the App,” it applies equally to the Site unless that section is plainly specific to the mobile app — for example, Section 8 (subscriptions, which are sold only in the App) and Section 10 (data stored on your device). Sections 6, 7, 11, 12 and 13 — the medical disclaimer, the isotretinoin safety notice, the disclaimer of warranties, the limitation of liability, and indemnification — apply in full to your use of the Site and every tool on it.

You do not need an account for either the App or the Site. Using the Site's tools requires nothing to be submitted to us: they run in your browser, and we receive none of what you enter.

3. Eligibility and Age Requirement

No Use by Children Under 13: Cleyra is not intended for children under 13 years of age. You must be at least 13 years old to use the Services.

Teen Users 13-17: If you are between 13 and 17, you should only use Cleyra with the involvement and consent of a parent or legal guardian.

4. Account-Free Experience

We do not require you to create a user account or login. The app is fully functional without account-based features. Because there is no account, you are responsible for maintaining access to your app data on your device. There is no password or account recovery.

The Site's tools are also account-free, and they keep nothing: what you enter into a calculator lives only in your browser for as long as the page is open, and is gone when you reload or close it. Nothing you enter there is saved for you or transmitted to us, so there is nothing on the Site for you to recover, export, or delete.

5. Personal, Lawful Use Only

We grant you a personal, non-transferable, non-exclusive license to use Cleyra solely for your own personal health-tracking purposes. You agree not to use Cleyra for any commercial or unlawful purposes.

6. Medical Disclaimer – No Medical Advice or Diagnosis

• The App is intended solely for personal tracking and informational purposes
• The App does not diagnose, treat, cure, or prevent any disease or condition
• The App is not a substitute for professional medical advice, diagnosis, or treatment
• Always seek the advice of your dermatologist or other qualified health provider
• Never disregard professional medical advice or delay seeking it because of something you tracked in this App
• The App does not verify medication compliance or replace programs like iPledge
• The app does not contact emergency services — seek medical attention immediately for severe side effects
• Calculators and trackers on the Site — including any cumulative-dose or progress estimate — perform arithmetic on figures you enter and compare the result to general published ranges or to a goal you supply. They have no knowledge of your prescription, labs, side effects, or medical history. Their output is an estimate, never a dose recommendation, and never a reason to start, stop, or change a dose
• Published dose ranges shown anywhere in the Services are population guidelines drawn from medical literature, not a target calculated for you. Only your prescriber can set your dose or your total

7. Isotretinoin (Accutane) Safety Notice

• Follow All Safety Protocols: In the U.S., isotretinoin is regulated under the iPLEDGE program. This app is independent of iPLEDGE.
• Pregnancy Warning: Isotretinoin can cause severe birth defects. Adhere to required contraceptive measures and pregnancy testing as mandated by your doctor.
• Side Effect Monitoring: Recording a symptom in the app does not trigger any intervention. Inform your healthcare provider of significant side effects.
• Dermatologist Supervision: Use this app only as a supplement to regular check-ups.

8. Subscription and In-App Purchases

Cleyra offers core features with optional premium features available through subscription.

• All billing is handled by Apple or Google. Subscriptions auto-renew unless cancelled 24 hours before the period ends.
• Manage or cancel via your platform's subscription settings.
• Subscription fees are generally non-refundable. Request refunds through Apple or Google.

9. Intellectual Property Rights

The Cleyra app and the Site, including their text, design, and the tools published on the Site, are the intellectual property of Michael Curtis (Cleyra) and are protected by copyright, trademark, and other applicable laws. Your personal data and content remains yours.

Accutane® Trademark:“Accutane” is a registered trademark of its respective owner. Cleyra is not affiliated with, endorsed by, or sponsored by the makers of Accutane. We use the term solely in a descriptive, nominative sense.

10. Data Loss and Device Responsibility

11. Disclaimer of Warranties

The Services — the App and the Site, including every calculator, tracker, and article on it — are provided “as is” and “as available,” without any warranties of any kind, express or implied. We do not warrant that any figure, estimate, projection, or published range shown in the Services is accurate, complete, current, or suitable for your circumstances. You use the Services at your own discretion and risk.

12. Limitation of Liability

Under no circumstances will Michael Curtis or Cleyra be liable for any indirect, incidental, consequential, special, or exemplary damages, or for any decision you or anyone else makes about isotretinoin treatment in reliance on the Services. Our total liability, whether arising from your use of the App or of the Site, shall not exceed the amount you paid us for the Services in the past 12 months (or $50, whichever is greater). This limit applies even though the Site is provided free of charge.

13. Indemnification

You agree to indemnify and hold harmless Michael Curtis (Cleyra) from claims arising from your use of the Services in violation of these Terms.

14. Termination

You may terminate this agreement by uninstalling the app and ceasing to use the Site. We reserve the right to suspend or terminate access if you violate these Terms.

15. Governing Law

These Terms shall be governed by the laws of the State of California, USA.

16. Dispute Resolution & Arbitration

Disputes will be settled by binding arbitration under the AAA Consumer Arbitration Rules. You may opt out within 30 days by emailing support@cleyra.skin.

17. Modifications

We may modify these Terms from time to time. Continued use after changes constitutes acceptance.

18. Severability

If any provision is held invalid, the remaining provisions remain in full force.

19. Entire Agreement

These Terms together with the Privacy Policy constitute the entire agreement between you and Cleyra.
