Privacy Policy

This policy explains how FLLW collects, uses, shares and protects your information. FLLW holds sensitive information such as your weight, body measurements and body photos, so we tell you plainly what we collect, who can see it, how long we keep it and how you can delete it. For information about consumer health data under Washington, Nevada, Connecticut and similar state laws, see our Consumer Health Data Privacy Policy. This policy applies if you live in the United States. If you live in Japan, our Japanese privacy policy applies instead.

This is enforced by access rules in our database (row-level security), not just by the app's screens. The database does not return data to anyone outside these permissions.

5. How we share your information

We share your information with your coach so they can coach you. This is the core purpose of FLLW.

We use the following service providers to run FLLW. They process information only to provide their services to us.

Supabase, Inc. (US)Sign-in, database and photo and video storage
Vercel, Inc. (US)Hosting and server processing
Google LLC (US)Sending email notifications
Anthropic, PBC (US)AI summaries of weekly check-ins (section 6)
Stripe, Inc. (US)Payment processing for coach subscriptions
We do not sell your personal information or share it for cross-context behavioral advertising. We may disclose information if required by law or to protect someone's life, health or safety.

6. AI summaries

To help your coach read weekly check-ins, we may send the check-in to an AI service (Anthropic, PBC) to prepare a summary. Your coach can turn this feature off.

What we sendThe text and numbers in your weekly check-in, including condition, sleep, fatigue, stress and whether you reported pain
What we don't sendYour photos, form videos, name or email address. Please avoid writing identifying details in free-text answers.
Who sees the resultOnly your coach. Your coach reviews it before using it; it is never sent to you automatically.
Model trainingAnthropic does not use this data to train its models.
RetentionAnthropic deletes it within 30 days, except where it is flagged for violating Anthropic's usage policies.
You can ask us to stop sending your check-ins for AI summaries at any time by emailing info@fllwapp.com. This does not affect your use of FLLW.

7. How long we keep your information and how to delete it

While your account is activeWe keep your records while your account exists.
Deleting items in the appWhen you delete a weekly check-in or training record in the app, it disappears from view right away. So that offline devices do not bring it back, a deleted copy stays in our database until you delete your account or ask us to erase it.
Erasing specific informationEmail info@fllwapp.com and we will erase the information you specify, including health information, without closing your account.
Deleting your accountYou can delete your account yourself in the app (Settings → Delete account). This permanently deletes your account and all related records, photos and videos. It cannot be undone.
BackupsWe keep backups to protect against data loss. Deleted information can remain in a backup until that backup is deleted. We delete backups within six months and do not restore deleted personal information from them except to recover from an incident.

8. How we protect your information

If a security incident affects your information, we will notify you and the authorities as required by law.

9. Your choices and rights

You can see, correct and delete most of your information yourself in the app. You can also email info@fllwapp.com to request a copy of your information, a correction, deletion, or a list of the service providers that received it. We will verify your request using information reasonably necessary to confirm it is you, and respond within 45 days.

Depending on where you live, you may have additional rights under state law. We will not discriminate against you for exercising your rights. Residents of Washington, Nevada, Connecticut and other states with consumer health data laws: see our Consumer Health Data Privacy Policy.
