Privacy policy

• Your account: your name and email from Google or Apple when you sign in (with Apple you can hide your email; we then get a relay address).
• What you log: workouts, sets, programs, body weight and measurements, activities, and notes.
• Your profile: what you tell the coach about yourself, such as birth date, height, training history, goals and injuries.
• Steps from Apple Health, if you allow it: daily step counts only, read and never written.
• Your coach conversations, and the coach's notes about you that keep it consistent over time.
• Usage counts for the coach (how much you used it each day), to keep within daily limits.

Only to run the app for you: to show your history and to let your coach plan and adjust your training. No ads, no selling or sharing your data for marketing, and no tracking across other apps or websites.

The coach runs on Claude, made by Anthropic. When you message the coach, your message goes to Anthropic's API along with what the coach needs to answer: your profile, recent training and body data, the coach's notes and the recent conversation. Anthropic processes it to write the reply and, under its commercial terms, doesn't use it to train its models.

• Vercel hosts the app and Neon stores the database.
• Google and Apple handle sign-in.
• Voice input is turned into text by your device's speech service (Apple on iPhone, your browser on the web); the app receives only the text.

The only cookie is the one that keeps you signed in.

Your data stays until you delete your account. To delete it, go to Profile → Delete account and type delete. That removes your account and everything in it right away, and revokes Sign in with Apple. Copies in the database provider's backups expire within a few days.

Quadzilla isn't meant for anyone under 18.
