Privacy Policy
Last updated: June 23, 2026
1. The short version
Flank exists to help you train. We collect the minimum data we need to do that, we never sell it, and we let you delete it on demand.
2. What we collect
- Account data: name, email, phone number (for OTP sign-in), and basic profile (height, weight, training goal, equipment access).
- Training data: workouts you log, nutrition entries, hydration, sleep notes, and any chat messages with the AI coach.
- Device data: app version, operating system, crash logs, and rough geographic region from your IP address.
3. How we use it
- Generate and adapt your personalised training and nutrition plan.
- Power the AI coach chat using retrieval over your own history.
- Send transactional emails and security notifications.
- Debug crashes and improve product reliability.
4. Who can see your data
Only you, and a small number of Flank engineers under audit. We use infrastructure partners (cloud hosting, error tracking, payments) who process data on our behalf under written agreements. We do not sell or share your data with advertisers.
5. AI processing
Flank uses large language models to generate plans and answer your questions. Where third-party AI providers are used, they process data under no-retention or zero-retention agreements where available, and they do not train their models on your data.
6. Your rights
- Export your data in machine-readable form, at any time.
- Delete your account and all associated data.
- Object to specific processing (e.g. analytics).
- Lodge a complaint with your local data-protection authority.
7. Retention
We keep your data while your account is active. If you delete your account, we remove it from our production systems within 30 days and from backups within 90 days.
