SummaFit is a clean, local-first app designed for daily nutrition tracking. It allows you to monitor your calories, macronutrients (protein, carbs, fats), water intake, and body weight logs without any ads, accounts, or mandatory cloud servers.

Your tracking history, favorites, and settings are stored in your iPhone's local sandbox, and your profile is protected with AES-GCM. SummaFit does not upload your health history to its own servers; barcode lookups and optional Apple Health features use the outside services described in the privacy policy.

No. You won't need to register, create a password, or sign in with an email. You can start tracking food and water without creating an account.

Yes. Apple Health integration is optional. With your permission, SummaFit can read steps, active energy, body mass, and walking or running distance, and can write body mass, dietary energy, and water entries to the Health app.

You can export all your logged data as a clean JSON file directly from the app Settings. You can save this file to your device's Files app, iCloud, or share it. To clear your data, you can delete it from the Settings or simply delete the app.
