Privacy Policy

The Tesserone app does not collect, transmit, or share any of your data. Everything you enter stays on your device. This website only counts visitors in aggregate — see below.

None from the app. The app does not collect any personal information, usage analytics, crash reports, device identifiers, or any other data. There is no account, no sign-up, and no profile. The app does not communicate with any server we operate — because we don't operate any.

The loyalty cards you add (name, barcode, notes, chosen logo or colour, custom uploaded logos) are stored locally on your device using the operating system's standard storage. This data never leaves your device unless you explicitly export it yourself using the Export feature.

• Camera — used only when you tap "Scan" to read a barcode. Frames are processed on-device and are never saved or transmitted.
• Photo library — used only when you pick a custom logo image for a card. The image is copied into the app's private storage; no gallery access happens in the background.

The app contains no third-party SDKs, advertising networks, analytics services, or tracking tools. It makes no network requests in normal use.

tesserone.com uses Cloudflare Web Analytics for a privacy-first, cookie-free count of page views and visitors. No personal profiles, no fingerprinting, no ads. It does not see the app or the cards on your phone. Hosting providers may still process technical data such as IP addresses under their own policies.

The app does not knowingly collect information from anyone — including children under 13 (or the equivalent minimum age in your jurisdiction). Website visitor counts are aggregate and cookieless. Chipcolate cannot identify you from either, so there is nothing personal to delete or export on request.

Regulations such as the GDPR and CCPA give you rights to access, correct, or delete personal data held about you. Chipcolate holds no personal data about Tesserone app users, so there is nothing from the product for us to provide or erase. Your cards reside entirely on your device, under your control — you can delete a card or uninstall the app at any time to remove them. Website visitor counts are aggregate; we cannot look someone up from them.

If this policy changes, we will update the effective date above and note the change in the app's release notes. Because the app's approach is "collect nothing," material changes would only occur alongside a significant redesign.
