Privacy Policy
Last updated 5 October 2026
Blade is operated by Blade ("we"). This policy explains what the Blade app and this website collect, why, and what you can do about it. Questions: rolandofgill2@gmail.com.
What we collect
- Account: your email address and your password, stored only as a one-way hash.
- What you log: foods and their macros, what you eat each day, weigh-ins, what you write in your journal, body measurements, and the phases (cut, bulk, maintain, break) you set.
- Coach conversations: the questions you ask the AI coach and its answers.
- Meal photos: only the photos you choose to have estimated. They go to the AI for the estimate and are not stored by us.
- Subscription status: whether Blade Pro is active, which plan, and until when. Payments are handled by Apple or Google; we never see your card details.
- Technical data: IP address and request times in server logs, kept briefly for security.
We don't use advertising, we don't track you across other apps or websites, and we don't sell or rent your data.
Why we use it
- To run the app: store your logs, compute your totals, trends, maintenance estimate and phase verdicts, and show them back to you.
- To answer your coach questions and estimate meal photos, only after you allow it (see below).
- To confirm your subscription and unlock Blade Pro.
- To send you a password reset code when you ask for one.
- To keep the service secure and working.
Your weight, food and measurements are health related data. We process them only to provide the features you use, based on your consent, which you can withdraw by deleting the data or your account.
The AI coach
The coach is powered by Claude, an AI model provided by Anthropic, PBC. The first time you open the coach, the app asks your permission. When you ask a question, we send Anthropic your question, the recent conversation, and the data needed to answer it: your food log, weigh-ins, journal, measurements and phases. When you ask for a photo estimate, we send the photo you chose. Anthropic processes it as our service provider to generate the answer and, under its commercial terms, does not use it to train its models. You can switch the coach's access off at any time in Settings. AI answers can be wrong; they are not medical advice.
Who else processes your data
- Our hosting provider, which runs the servers that store your data.
- Anthropic, for coach answers and photo estimates, as described above.
- RevenueCat, Apple and Google, to sell and verify subscriptions.
- Our email provider, to send password reset codes.
These providers may process data outside your country. Where the law requires it, transfers are covered by appropriate safeguards such as standard contractual clauses.
How long we keep it
For as long as you have an account. When you delete your account, your data is deleted from our database at once and disappears from backups within 30 days.
Your choices and rights
- Export: Settings, Export my data, gives you everything as a file.
- Correct: edit or delete any entry in the app.
- Delete: Settings, Delete account, or the account deletion page. Deleting your account does not cancel a subscription: cancel it in your App Store or Google Play settings.
- Withdraw coach access: Settings, AI coach access.
- Depending on where you live you may also have the right to access, restrict or object to processing, and to complain to your data protection authority.
Security
Data travels over HTTPS, passwords are hashed with Argon2, and each account can only reach its own data.
Children
Blade is not meant for anyone under 16. If you believe a child has created an account, write to us and we will delete it.
Changes
If this policy changes in a way that matters, we will say so in the app before it takes effect.
