8. Cookies and Similar Technologies

Sub-reminder is a mobile application and does not use traditional web cookies. However, we use similar technologies:

• Local Storage: We use local device storage (Room database, SQLDelight, SharedPreferences/UserDefaults) to store your subscription data and app preferences
• Advertising Identifiers: Google AdMob uses Android Advertising ID and iOS IDFA for ad personalization and measurement. You can reset these identifiers or opt-out of personalized ads through your device settings
• Analytics Identifiers: Analytics services use unique, anonymized identifiers to track app usage across sessions (these identifiers do not personally identify you)
• Crash Reporting Identifiers: Crash reports may include device identifiers to help diagnose issues, but these are anonymized and not linked to your identity

You can reset your advertising identifier (Android: Settings > Google > Ads > Reset advertising ID; iOS: Settings > Privacy > Apple Advertising > Reset Advertising Identifier) to change your analytics and advertising identifier.

9. Children's Privacy

Sub-reminder is not intended for users under the age of 13 (or 13 in jurisdictions that require it, such as the United States under COPPA). We do not knowingly collect personal information from children under this age. If you are a parent or guardian and believe your child has provided us with personal information, please contact us immediately, and we will delete such information.

If you are located in the EEA, the minimum age may be 16 (or lower if your country permits). If you are under the applicable minimum age, please do not use Sub-reminder without parental consent.

10. International Data Transfers

If you are located outside your home jurisdiction, your information may be transferred to and processed in other countries where our service providers (such as Google AdMob) operate. These countries may have different data protection laws than your country.

• Google AdMob: Data is processed by Google, which operates globally. Google complies with applicable data protection laws, including GDPR, and provides appropriate safeguards (such as Standard Contractual Clauses) for international transfers.
• EU/UK Users: If you are in the EEA or UK, we ensure that international transfers are subject to appropriate safeguards as required by GDPR.

By using Sub-reminder, you consent to the transfer of your information to these countries.
