THYKO — Privacy Policy & Support

Last updated: August 20, 2026

THYKO ("the app") is a loyalty card wallet developed by Daniele Costarella. This policy explains how the app handles your information.

THYKO does not collect, store, or share any personal data. The app has no user accounts, does not connect to the internet, and does not use any analytics, advertising, or tracking services.

What THYKO stores

All the information you enter into THYKO — card names, barcodes, photos you attach to a card, and any notes — is stored only on your own device, in the app's local database. Nothing is ever uploaded, backed up to a server, or made accessible to the developer or any third party.

Camera access

THYKO requests camera access solely to let you scan a barcode when adding a card. Scanning happens entirely on your device; no image or video is recorded, stored, or transmitted anywhere.

Sharing a card

If you choose to share a card with someone else (via QR code, image, or file export), that action is entirely under your control and happens directly between your device and the recipient's — no server or third party is involved, and the developer has no visibility into what is shared or with whom.

Data deletion

Since no data ever leaves your device, deleting a card in the app or uninstalling THYKO permanently removes that data. There is nothing for the developer to delete on your behalf, because nothing is ever received.

Children's privacy

THYKO does not knowingly collect any information from anyone, including children, because it does not collect information at all.

Changes to this policy

If this policy ever changes (for example, if a future version of THYKO adds an optional feature that involves data leaving the device), this page will be updated and the change will be described in the app's release notes.
