Privacy Policy – Ferrio App

1. Data Controller

The data controller is Andrzej Chmiel, publisher of the Ferrio mobile app.

Contact: andret2344@gmail.com .

2. Data Collected

Ferrio processes the user's email address and a unique identifier (UID) when logging in via Firebase Authentication.

The email address is used solely to:

• • link reports (holiday error reports or missing holiday suggestions) to the user's account,
• • block an account in case of abuse (e.g., spam).

Anonymous login is also available. In this case, no personal data is collected, but anonymous users cannot use the reporting feature.

3. Data Storage and Processing

Data is processed using Firebase (Google LLC).

User identifiers are additionally stored on the administrator's server (OVH, EU) to associate reports with accounts.

4. User Reports

Users can report errors in holiday information or suggest missing holidays.

The reporting feature is available only to authenticated (non-anonymous) users. Anonymous accounts cannot submit reports, as they cannot be identified or blocked in case of abuse.

Report contents may include personal information entered voluntarily by the user. Such data is not required or used for any other purpose.

5. Purpose and Legal Basis

Data is processed only to:

• • operate user accounts,
• • link reports to users,
• • prevent misuse.

The legal basis is the legitimate interest of the controller under Article 6(1)(f) of the GDPR.

6. Data Sharing

No data is shared with third parties except for Firebase, which acts as a data processor under Google's terms.

7. Retention Period

Data is stored as long as the user keeps using the app.

To request deletion of your data, please send an email to andret2344@gmail.com .

Anonymous accounts do not store personal data and can be reset by clearing the app data.

8. User Rights

Users have the right to:

• • access their data,
• • request deletion, correction, or restriction of processing,
• • object to processing,
• • file a complaint with a supervisory authority.

9. Security

All data is protected in accordance with current Firebase security standards.

10. Changes

The privacy policy may be updated. The current version will always be available in the app and on ferrio.app.
