This policy covers all apps developed under the Quasar Lab brand.

Fialina

// Data storage

All personal data (goals, diary entries, habit tracking, notes) is stored locally on your device. We do not operate a cloud sync service for this data. Deleting the app permanently removes all associated data.

// Authentication

Sign in is handled via Apple Sign In. We receive only an anonymous user identifier — no email or name is stored on our servers unless you explicitly choose to share them with Apple.

// AI Analysis ("State" screen)

To generate personalized insights, the app sends the following to OpenAI:

  • →Aggregated mood statistics (%, no raw data)
  • →Tag correlation summaries
  • →Goal activity patterns
  • →Excerpts from your personal diary notes (used as qualitative context)

These data points are transmitted through our proxy server and are not stored by OpenAI beyond the duration of the API request. Your user identifier is not included in AI requests — this data is not linked to you.

// Subscription

Subscription management is handled by RevenueCat and Apple. We receive only the subscription status and expiry date — no payment details.

// Analytics

We collect anonymous activity signals (check-in events, without content) to measure app retention. No personal content leaves your device as part of analytics.
