Date of Publication: July 24, 2025
This document outlines the principles of personal data processing and the use of technical information
by the Auction Mate browser extension (hereinafter: the "Extension").
In the event of any discrepancies between this version of the Privacy Policy and versions in other
languages, the provisions of the Polish-language version shall prevail.

1. Data Controller
   The data controller is a natural person. Contact email: support@auction-mate.net
   The controller provides the Extension free of charge as a personal hobby project.
2. Scope of Data Processing
   The Extension may automatically process the following technical data:
   • the user's device IP address,
   • a randomly generated identifier (e.g., UUID),
   • the URL of the viewed listing or auction,
   • price and local comparative visualization (without storing detailed data).
3. Purposes and Legal Basis for Processing
   Data is processed solely for the following purposes:
   • to ensure the proper operation of the Extension (Article 6(1)(f) GDPR – legitimate interest),
   • performance monitoring and error diagnostics (Article 6(1)(f) GDPR),
   • anonymous statistics (upon user consent – Article 6(1)(a) GDPR).
   The data is not used for profiling or marketing purposes.
4. Data Transfer Outside the EEA
   In connection with the operation of the Extension, data may be processed by cloud service providers
   such as:
   • Microsoft Azure, which may involve the transfer of data outside the European Economic Area
   (EEA). In such cases, appropriate safeguards are applied in accordance with Article 46 GDPR
   (e.g., standard contractual clauses).
5. Data Retention Period
   Data is retained as follows:
   • IP addresses and UUID identifiers: up to 60 days,
   • diagnostic/statistical data: until anonymized or deleted (no longer than 60 days).
   Data is automatically deleted or anonymized after the above retention periods.
6. User Rights
   You have the right to:
   • request access to your data,
   • request rectification or deletion of your data,
   • request restriction of processing,
   • object to processing,
   • data portability (where technically feasible),
   • lodge a complaint with the President of the Personal Data Protection Office (uodo.gov.pl) if you
   believe your data is being processed in violation of the GDPR.
7. User Age
   The Extension may only be used by individuals who are at least 16 years of age or have the consent of
   a legal guardian.
8. Security Measures
   The controller implements appropriate technical and organizational measures, including:
   • encrypted connections (HTTPS/TLS),
   • restricted data access,
   • storing only the information necessary for operation,
   • anonymizing data as quickly as possible.
9. Cookies and Local Technologies
   The Extension does not use cookies for marketing or advertising purposes.
   It uses the browser's local storage (localStorage/sessionStorage) solely to store temporary data required
   for comparison functionality – this is stored locally and not transmitted to any server.
10. Changes to the Privacy Policy
    This policy may be periodically updated. Changes will be published in the repository or extension store
    from which the Extension was downloaded. Continued use of the Extension after changes are made
    constitutes acceptance of the updated policy.
