FittyBitty ("the App") is developed by Geoff Baron. This policy explains what data the App collects, how it is used, and your rights.
Your profile, plan and logs are stored on your phone. There is no account and no sign-up. The only things that leave your phone are what you send to the AI coach: your messages, any meal photos you ask it to estimate, and a short summary of your day so its answers fit you. Those go to our coach service to produce a reply. We do not sell your data or use it for advertising.
Profile information you provide: name (optional), age, sex, height, weight, goal weight, activity level, fitness objectives, equipment, workout style, travel mode, and notification preferences. Used on-device to generate your workout plan.
Your logs: workouts and sets, food-diary entries and any meal photos you attach, water, weight history, XP, streaks, badges, and your conversation with the coach. All written to on-device storage (Hive and the App's file storage). Deleting the App deletes all of it.
Step count and activity (Apple Health): if you grant permission, the App reads your step count, active energy, exercise minutes and workouts from Apple Health to complete your daily targets. This is read-only — the App never writes to Health — and Health data itself is never sent off your device.
Voice: when you talk to the coach, speech is turned into text by Apple's speech recognition. The App sends the resulting text, not a recording.
When you message the coach or ask it to estimate a meal photo, the App sends:
This is used only to produce the coach's reply and meal estimates. It is sent under a random, anonymous identifier created for your install — not your name, email or Apple ID.
The coach runs on Harbor (harbor.it.com), our backend provider, which passes the request to Anthropic (the maker of the Claude AI model) to generate the reply. Both process the content only to provide the service and may keep limited records, such as usage counts for billing and abuse prevention, under their own privacy policies. Anthropic does not use this data to train its models. We do not keep a separate copy of your messages or photos on any server.
If you never use the coach's chat or photo features, nothing about you leaves your phone.
Coach Unlimited is sold through Apple's App Store. Apple handles payment; we never see your card details. We use RevenueCat (revenuecat.com) to check whether a subscription is active. RevenueCat receives an anonymous app user ID and your App Store purchase receipts, and nothing about your health, food or workouts.
On-device data persists until you delete the App or clear the coach conversation. Content sent to the coach is used to produce a reply and is not stored by us afterwards. Any limited records kept by Harbor, Anthropic or RevenueCat follow their own retention policies.
The App is rated 4+ and does not knowingly collect personal information from children under 13. It has no accounts, and the coach receives only the content described above under an anonymous identifier.
Uninstalling the App deletes every piece of data it holds on your phone. We keep no account or server-side copy of your data, so there is nothing further to request — but you are welcome to email geoffbaron@gmail.com with any question.
We may update this policy from time to time. The updated version will be posted at this URL with a revised effective date.
