Privacy

The short version. Your training and health data stay on your iPhone and in Apple Health. If you turn on the Claude coach, DUVRO sends the data each coaching request needs to Anthropic, the company that makes Claude, and nowhere else. Your health data is never sold, never used for advertising and never shared with data brokers.

What stays on your device

Workouts, routines, logs, recovery sessions, your profile, chat history and coach reports are stored on your iPhone and Apple Watch. Data DUVRO reads from Apple Health stays in Apple Health. For weather, your location is rounded to about 1 km before it's sent to Apple Weather (Apple's WeatherKit service) to look up the forecast.

What the coach sends, and why

Only when you've agreed in the app and you use a coach feature (morning brief, weekly report, program builder, metric insight or chat), DUVRO sends Claude the information that request needs: workouts, heart rate, HRV, resting heart rate, sleep, steps, VO₂ max and bodyweight from Apple Health; your logged sessions, routines and recovery; your profile and goals; your chat messages; and the day's weather. It goes from the app to DUVRO's server, which passes it to Anthropic's API and returns the answer. DUVRO's server does not store the request or the answer.

Anthropic processes API requests under its commercial terms and privacy policy (anthropic.com/legal/privacy).

What DUVRO's server keeps

Your Sign in with Apple user ID, a random identifier from Apple. DUVRO doesn't ask for your name or email.
Counts of coach requests per day and per month, to keep usage within fair limits. These expire after about 40 days.

Subscriptions

Purchases are handled by Apple. DUVRO receives Apple's signed record of your subscription to confirm it's active; it never sees your payment details.

What DUVRO never does

Sell or rent your data.
Use health data for advertising or marketing, or share it with data brokers or advertisers.
Include third-party analytics or ad trackers.

Your choices

Turn off Claude coaching anytime in Settings; nothing more is sent.
Change which Health data DUVRO can read in the Health app.
Delete your account in Settings › Account. That removes your user ID and usage counts from DUVRO's server. Deleting the app removes the data stored on your device.

Not medical advice

DUVRO's coaching is general fitness guidance, not medical advice. Talk to a qualified professional about pain, injury or health concerns.

Children

DUVRO is not directed to children under 13.

Changes

If this policy changes, the new version will be posted here with a new date.
