Summary: The Leileat mobile app does not use HTTP cookies in the traditional web sense. It instead uses technical identifiers and, only with your prior consent, advertising identifiers. The leileat.com website uses exclusively technical cookies necessary for operation.
This Cookie Policy supplements the Privacy Policy and describes specifically the use of cookies, SDKs, and tracking technologies by the Leileat mobile application and the leileat.com website.
In the web context, cookies are small text files that a website stores in the user's browser. In the mobile context, analogous mechanisms are implemented through identifiers assigned by the SDK or the operating system, such as:
| Name | Provider | Purpose | Duration |
|---|---|---|---|
| Firebase Auth Token | Maintain the user's login session | 1 hour (automatic renewal) | |
| Firebase Installation ID | Pseudonymous installation identifier, necessary for the operation of Firebase services | Until app uninstallation | |
| RevenueCat App User ID | RevenueCat | Associate the Premium subscription with the device | Until uninstallation |
| SharedPreferences / UserDefaults | Leileat app | Save local preferences (theme, language, onboarding flag) | Until uninstallation |
Legal basis: legitimate interest / contract performance (Art. 6(1)(b) and 6(1)(f) GDPR).
| Name | Provider | Purpose | Duration |
|---|---|---|---|
| Firebase Analytics | Aggregated usage statistics (screens viewed, events, subscription conversion) | 14 months | |
| Firebase Crashlytics | Crash reports and diagnostic logs | 90 days |
Legal basis: consent (Art. 6(1)(a) GDPR) in the EU; legitimate interest outside the EU.
| Name | Provider | Purpose | Duration |
|---|---|---|---|
| Google AdMob | Ad selection and display, impression counting | Up to 13 months | |
| IDFA (iOS) | Apple / Google | Ad personalisation — only with ATT consent | Until identifier reset |
| GAID (Android) | Ad personalisation — only with UMP consent | Until identifier reset |
Legal basis: explicit consent (Art. 6(1)(a) GDPR).
Important: in compliance with the GDPR and Apple's policies, by default only non-personalised ads are shown. Personalised ads are activated exclusively if the user provides specific consent via the in-app consent banner (Google UMP) and grants tracking via the App Tracking Transparency prompt on iOS.
The website uses exclusively first-party technical cookies necessary for operation (e.g. session, language preferences). No profiling or marketing cookies are installed without your consent.
At any time you can withdraw the consent given for non-technical cookies/SDKs, without any prejudice to the use of the Service (the Free version will remain fully functional without personalised ads).
We update this Policy in case of regulatory changes or the introduction of new technologies. The updated version will be published on this page with the relevant date.
