Positive Security Features

  • All communications with third-party services use secure, up-to-date network protocols
  • The codebase consistently applies safe data handling patterns throughout
  • Purchases are processed through RevenueCat, a dedicated payment platform, rather than custom-built payment handling

Areas for Improvement

  • Users have limited ability to opt out of behavioral data collection. There are no clear in-app controls to restrict what PostHog and Amplitude collect about user habits and activity.
  • The app integrates multiple overlapping analytics services, which increases the total volume of data collected about daily usage patterns.
  • Greater transparency around data retention periods and account deletion options would give users more meaningful control over personal information held by third-party services.
