Privacy and Data Deletion

Health data is sensitive, and FuelKit is built accordingly: your data exists to show you your numbers, nothing else.

What FuelKit stores

• Account: your Google identity (name, email, avatar) — used only to sign you in and label your household membership. There is no FuelKit password.
• Your data: profile and targets, food log, weigh-ins, activities, API keys, and any nutrition-label photos you've submitted.
• Household data: the shared food/recipe library, dinner plan, and grocery list, visible to your household members. Your food log is never shared — housemates see only daily progress totals.

What FuelKit doesn't do

• No ads, no analytics, no tracking pixels, no data sales. The app records nothing about your behavior.
• One diagnostic exception, disclosed plainly: if the app itself crashes or hits an internal error, it sends an automated error report — the technical error message and where in the code it happened — so bugs get fixed without you having to file them. These reports are about the app's health, not yours, and aren't used for anything else.
• Third parties are contacted only to do what you asked: Google to sign you in, the USDA/Open Food Facts databases to look up a food or barcode (your query, never your identity or log), and your AI assistant only if you connect one.

Your data on your device

Recent data is cached on-device so the app works offline. Signing out wipes the local copies — the cached log, mirror, and API responses — so a shared or borrowed browser doesn't keep your history.

Export your data

Profile → Data & backup → Export downloads your complete data as a single JSON file: profile, foods, meals, logs, weights — a portable, human-readable copy that's yours to keep. Import restores from such a file; note that restore replaces your current data with the file's contents.

Delete your account

Profile → Delete account permanently removes your account after a confirmation. It deletes your log, weights, activities, profile, sessions, API keys, label photos, and feedback — immediately and irreversibly. There is no soft-delete or recovery window, so export first if you may ever want the history.

One household courtesy: if you shared a household, recipes you created are handed to a remaining member instead of vanishing from their kitchen. If you were solo, everything goes.
