Aivelo — Privacy Policy
Who we are
Aivelo is a calorie and nutrition tracker published by DELTA VIDEO GAMES LTD. This policy explains what the app collects, why, and the choices you have.
What stays on your phone
Meals, photos of your meals, weight, water, sleep, steps, fasting and your goals are stored on your device. You can use the app as a guest without an account.
Account and cloud backup
If you create an account (email or Google), your email address and an account ID are handled by Google Firebase Authentication.
Signed-in users can back up their app data. The backup is stored on Cloudflare R2, linked to your account ID, and is deleted when you delete your account.
AI meal analysis
When you scan a meal, the photo (and any words you add) is sent over an encrypted connection to our server on Cloudflare and analysed by an AI model (Cloudflare Workers AI). The photo is not stored on the server and is not used to train models. Voice logging sends the text of what you said, not the audio.
Results are estimates for general wellness, not medical advice.
Health Connect
With your permission, Aivelo reads and writes steps, weight, sleep, exercise, nutrition and calories burned in Health Connect. This data is used only inside the app to show your progress. It is never sold, never used for advertising, and never shared with third parties.
Advertising
The app is free and shows ads from Google AdMob (and Yandex Ads in some regions). Ad networks may use your device's advertising ID and approximate location to show and measure ads. In the European area we ask for your consent first; you can change it any time in Settings → Ad privacy options, and you can reset or delete your advertising ID in your phone settings.
Diagnostics and analytics
Google Firebase Crashlytics collects crash reports, and Firebase Analytics collects anonymous usage events (for example which screens are opened) to improve the app. Firebase App Check verifies that requests come from the genuine app.
Sharing
We do not sell your personal data. Data is shared only with the service providers named above, to run the features you use.
Security and retention
Data in transit is encrypted (HTTPS). Server-side data (account, backup) is kept until you delete your account. Usage counters on the server keep only daily totals.
Children
Aivelo is not intended for children under 13 (under 16 in the European Union).
Your rights
You can see, correct and delete your data in the app at any time. To delete everything, use Settings → Delete account (see the account deletion page).
