Privacy

MacroArk stores the information needed to provide your private nutrition and weight tracking: account ownership, preferences, goals, foods, meals, logs, weight entries, and optional reminder settings. For reviewed provider, AI or imported foods, we retain structured original and final food values privately to describe corrections. This evidence is included in account export and removed with account deletion; it is not shared learning or model training data. Raw AI descriptions and recipe URLs are not stored.

We do not copy your Google email, profile image, or Google tokens into the application database. Optional browser push subscriptions are used only for reminders and can be disabled.

You can download your application data or delete it from Settings. Data remains until you delete it or delete your account. Provider services process only the data required to provide authentication, hosting, database, food-search, and optional notification functionality.

AI food estimation is optional. If you submit a food description for an AI estimate, that text may be processed by Google Gemini, the configured AI provider. You can log foods without using AI. The public demo uses illustrative local estimates and does not submit descriptions to Gemini.

Do not include secrets, credentials, or sensitive medical information in support requests.
