Privacy Policy - Sealva

Your privacy is important to us. This policy explains how Sealva handles your data.

Data Processing

Sealva uses your device's camera permission to scan barcodes containing Visible Digital Seals (VDS). All barcode data is decoded and processed locally on your device. No barcode information is transmitted to external servers or stored in the cloud.

User Control

You have full control over your data. All scanned information can be accessed through the "Scan History" menu within the app. You can delete any or all stored scan data at any time without affecting the app's functionality.

Data Retrieval from Server

To verify the digital signatures contained in VDS barcodes, Sealva retrieves current verification certificates from a self-hosted server. This happens automatically on first startup and whenever you explicitly request a certificate update.

Additionally, the app downloads current municipal directories and postal code databases to provide improved display and interpretation of the information contained in the seals. These reference data help to present location information in a more user-friendly format.

When connecting to the server, standard server logs may temporarily record your device's IP address. This information is used exclusively for maintaining server security and operational stability.

No Data Misuse

Sealva will not use or collect your personal data for any purpose other than those stated in this policy. The app contains:

No advertising
No user tracking
No analytics
No data sharing with third parties
