We collect and store Firebase Cloud Messaging (FCM) tokens to send you push notifications. These notifications may include:

  • Reminders to log your meals
  • Updates about your calorie tracking progress

Your FCM token is a unique device identifier that allows us to send notifications to your specific device. This token does not contain any personal information about you.

AI and Image Processing

Our app uses artificial intelligence to analyze meal photographs and calculate calorie content. The images you upload are processed by our AI system and stored in our database. We do not share these images with third parties except as necessary to provide the AI calorie calculation service. Your meal images are associated with your account for tracking purposes.

Token System and Advertisements

For free tier users, we implement a token-based system where users can watch advertisements to earn tokens. Each advertisement viewed grants 10 tokens, and tracking a meal (via photo or manual entry) requires 20 tokens. We work with third-party advertising partners who may collect information about your device and ad interactions. Please review the privacy policies of our advertising partners for more information about their data practices.We store your token balance, transaction history (including earned, spent, and expired tokens), and expiration dates in our secure database. This information is associated with your account and is deleted when you delete your account.

Token Expiration Policy:

  • All tokens earned through advertisements or other means have a 7-day expiration period from the date they are earned
  • Tokens that are 7 days old will automatically expire and be removed from your account balance
  • When using tokens for features, the oldest tokens (closest to expiration) are consumed first
  • Expired tokens cannot be recovered or reinstated
  • Your current token balance reflects only valid, non-expired tokens
  • We maintain transaction records showing token earnings, usage, and expirations for transparency

Data Storage and Security

We store your personal information and meal images in secure databases. We implement appropriate technical and organizational security measures to protect your data against unauthorized access, alteration, disclosure, or destruction. However, no method of transmission over the internet or electronic storage is 100% secure, and we cannot guarantee absolute security.
