Terms of Use

Effective date: August 31, 2026 · These Terms govern your use of the Fin iOS application ("Fin", "the App") and this website, operated by Welda LLC ("we", "us").

By downloading or using Fin, you agree to these Terms. If you do not agree, please do not use the App.

1. What Fin Is (and Is Not)

Fin is a self-help companion for building a streak away from a habit you choose to quit. It provides streak tracking, daily check-ins, motivational content, and calming exercises.

Not medical advice. Fin is not a medical device, does not provide medical, psychological, or therapeutic advice, and is not a substitute for professional care. Addiction can be a serious medical condition. If you are struggling — especially with alcohol or substance withdrawal, which can be dangerous — please seek help from a qualified professional or a local support service. If you are in crisis, contact your local emergency number immediately.

2. Eligibility

You must be at least 17 years old (or the minimum age indicated by the App’s App Store age rating in your region) and legally capable of entering into these Terms.

3. Subscriptions and Billing

4. Your Content and Data

Data you enter in Fin is stored on your device (see our Privacy Policy). You are responsible for maintaining your device backups. We are not liable for loss of locally stored data, including streaks.

5. Acceptable Use

You agree not to misuse the App or website, including attempting to reverse engineer, copy, resell, or interfere with them, or to use them in violation of applicable law.

6. Intellectual Property

The App, the Fin character, artwork, animations, copy, and branding are owned by Welda LLC and protected by intellectual-property laws. We grant you a personal, non-exclusive, non-transferable, revocable license to use the App for personal, non-commercial purposes on Apple-branded devices you own or control, consistent with the App Store terms.

7. Disclaimers

The App is provided “as is” and “as available” without warranties of any kind, express or implied, including fitness for a particular purpose. We do not warrant that the App will help you quit any habit, or that it will be uninterrupted or error-free.

8. Limitation of Liability

To the maximum extent permitted by law, Welda LLC shall not be liable for indirect, incidental, special, consequential, or punitive damages, or loss of data, arising from your use of the App. Our total liability for any claim shall not exceed the amount you paid us for the App in the twelve months preceding the claim. Some jurisdictions do not allow certain limitations, so parts of this section may not apply to you.

9. Apple as Third-Party Beneficiary

These Terms are between you and Welda LLC, not Apple. Apple has no obligation to furnish maintenance or support for the App and is not responsible for addressing claims relating to it. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

10. Changes and Termination

We may update the App and these Terms; the current version is always available on this page with its effective date. If you continue using the App after changes take effect, you accept the updated Terms. We may suspend or terminate access for violations of these Terms.

11. Governing Law

These Terms are governed by the laws of the jurisdiction in which Welda LLC is organized, without regard to conflict-of-law principles, and disputes shall be brought in the competent courts of that jurisdiction, except where mandatory consumer-protection law grants you the right to another venue.
