Vizitka

Last updated 15 October 2026

Vizitka is a digital business card app for Android, published by Patrik Šebek.

What data is collected

• Name, email address, phone number and address (if you enter one on the card).
• Other card details: company, position, website, note and photo.
• Every field is optional and entered by you. No account or sign-in is required.

How it is used

• Your card is stored on your phone. So that NFC and QR sharing work right after install with nothing to set up, the active card is also sent to our server (sebek.in) under a random identifier generated on your device.
• The transfer is always encrypted (HTTPS). The data is kept in its own database table, separate from anything else on the server, and your device key is stored only as a one-way hash.
• The data is used solely for app functionality: showing your card to someone who taps or scans.

What it does not do

• No analytics or crash reporting.
• No advertising or marketing.
• No sharing or selling of data to third parties.

Deleting your data

Deleting a card in the app also clears it from the server the next time the app syncs. To have everything removed (for example after uninstalling the app), email projects@sebek.in and it will be deleted.

Purchases

The one-time purchase that unlocks more cards is processed entirely by Google Play Billing. The app never sees or stores your payment details.
