6. Data Transfers to Third Countries
Most of the processing of personal data takes place within the European Union (EU) or the European Economic Area (EEA). However, in certain cases, we use services based outside these regions.
6.1 No Third-Country Transfers in the Following Cases:
- Supabase: Data processing (authentication and database storage) takes place exclusively on servers located in Germany (EU).
- Sentry: Error reports are processed on servers located in the EU (data center in Frankfurt, Germany).
Therefore, no transfer of personal data to third countries occurs with these providers.

- Apple Inc. (e.g., APNs, App Store)
- Google LLC (e.g., Firebase Cloud Messaging, Google Play Store)
- Vimeo Inc. (Video Streaming)
- Appsflyer Ltd. (Analytics & Attribution Tracking)
As the United States does not have a comprehensive adequacy decision from the European Commission (except for providers certified under the EU-U.S. Data Privacy Framework), such transfers are only carried out under appropriate safeguards, including:
- Use of EU Standard Contractual Clauses (SCCs)
- Additional protective measures (e.g., encryption, access controls)
6.3 Notice of Residual Risks
Despite the safeguards in place, when data is transferred to third countries—especially the United States—it cannot be entirely ruled out that government authorities may gain access to personal data. In such cases, EU residents may have limited legal remedies or means of redress.

You have the right to receive information about the safeguards used for data transfers to third countries. Upon request, we will provide you with a copy of the Standard Contractual Clauses used for such transfers.

You can delete your data at any time directly within the app or choose to delete your entire account. Upon account deletion, all associated data will be permanently and irreversibly erased.
7.2 No Statutory Retention Obligations
There are no legal retention obligations (e.g., under commercial or tax law) applicable to the data processed within our app. Therefore, data is stored solely based on your usage and consent.
