Firebase app instance and installation identifiers used by Google/Firebase services

Selected app usage and session events sent to Google Analytics for Firebase, such as app opens, onboarding steps, and selected in-app actions

Crash diagnostics sent to Firebase Crashlytics, such as app version, device model, operating system version, crash time, stack traces, and technical logs or keys needed to diagnose stability issues

Remote Config technical data needed to deliver configuration values, feature flags, logging settings, and safe rollouts

3. For what purpose is this data used?

The collected technical data is used exclusively to:

Manage licenses and Premium/Lifetime subscriptions

Analyze errors and improve service quality

Prevent abuse and detect fraud attempts (e.g., promotional abuse)

This data is not sold or shared with third parties for their independent marketing purposes.

Measure selected app usage and diagnostic events in Google Analytics for Firebase

Detect, analyze, and fix crashes and non-fatal errors using Firebase Crashlytics

Safely configure features, logging, rollouts, and app behavior using Firebase Remote Config

4. Is the data shared with third parties?

The App uses Google/Firebase services as technical service providers: Google Analytics for Firebase, Firebase Crashlytics, and Firebase Remote Config.

These services may process technical identifiers, device information, session information, selected app events, crash reports, and configuration requests only for analytics, stability diagnostics, and safe app configuration.

We do not intentionally send names, email addresses, phone numbers, authentication tokens, full API payloads, or private user-entered content to Firebase Analytics or Crashlytics.

Technical data is not sold and is not made available to third parties for their independent marketing purposes, except where required by applicable law.

The user has the right to obtain information about what technical data is processed in connection with the use of the App, and to request its deletion if technically possible.

Due to the lack of classic personal data, the collected data does not enable identification of specific individuals.
