WeekFit collects only what is needed to run the app: • An account identifier from Apple or Google, used to recognize you when you return. • Your email address, or Apple’s private relay email if you choose that option. • Training data you create, including plans, workouts, sets, personal records, custom exercises, and templates. • In-app preferences such as weight unit, default rest time, sound, and screen-on settings.
Your data is stored on your device and synced to our backend at Supabase, using a Postgres database hosted in the United States. Sync uses HTTPS. Supabase encrypts database storage at rest. We do not sell your training data. We do not use it to serve ads.
If you turn it on (Profile -> Sync to Apple Health; off by default), WeekFit connects to Apple Health: • It writes your completed strength workouts, and an estimated active-energy (calorie) value for each, to Apple Health. • It reads your most recent body weight, used to estimate the load of bodyweight exercises, and your heart rate for a workout when available, shown as an average.
Your Apple Health data stays on your device and in Apple’s Health app. WeekFit does not upload it to our backend or any third party, does not use it for advertising, and does not sell or share it. Body weight read from Health is stored only on your device.
You can turn this off anytime in WeekFit, or revoke access in iOS Settings -> Privacy & Security -> Health. Data already written to Apple Health stays there until you remove it in the Health app.
WeekFit uses these services:
Apple: Sign in with Apple. • Google: Sign in with Google. • Supabase: authentication and database hosting. • Meta: advertising measurement. • OpenAI or DeepSeek: AI plan generation. OpenAI is used outside the China App Store; DeepSeek is used for the China App Store.
These services receive only the data needed to provide their function. Supabase acts as a data processor for WeekFit.
Meta receives a device identifier and a few app events (such as completing onboarding or a workout) to measure how our ads perform. We do not collect the advertising identifier (IDFA), do not track you across other apps, and do not send Meta your training data, health data, email, or account.
When you generate an AI plan, WeekFit sends the AI provider your training goal, focus, experience, environment and equipment, training days, session length, app language, optional notes, and a list of eligible exercises. We do not send your name, email, or account identifier. The data is used only to create the plan — don't include sensitive personal or medical details in your notes.
You can delete your account anytime in the app from Settings -> Profile -> Delete Account. When you delete your account: • Local data is erased from this device. • Training data stored in our backend is deleted. • Your authentication record is removed. If your device is offline, cloud-side deletion may be delayed until the app can reach the network again.
