Privacy Policy for Stikkteller

1. Who we are

Stikkteller is published by U-Things, an independent app studio. This policy describes how the Stikkteller iOS and Android app handles your information.

If you have any questions about this policy, contact us at contact@u-things.com.

2. The short version

• We do not collect your name, email, or any personal identifier.
• We do not create accounts or user profiles.
• Your daily match count is stored only on your device.
• We collect only anonymous, aggregate usage counts (not linked to you).
• We do not sell data. We do not run ads. We do not share data with third-party marketers.

3. Data we collect

3.1 Match count (local only)

Stikkteller stores your remaining match count and the date of the last daily reset on your device using local storage (SharedPreferences on Android, NSUserDefaultson iOS). This is a small integer and a date key. It contains no personal data and never leaves your device.

3.2 Anonymous aggregate analytics

We capture a small number of anonymous event counts to understand how the app is used at a product level. Each event record contains only:

• An event name from a closed list: route_view, match_pulled, day_complete, buy_intent, bail_out.
• A coarse platform label: android, ios, or other.

No match history, no device identifiers, no IP address, no user identifier, and no personal data of any kind is included in these events. Collection is best-effort: if it fails (offline, network error), the event is silently dropped and the app continues normally.

Events are stored in Cloudflare Workers Analytics Engine, a privacy-preserving aggregate analytics product. See Cloudflare's Privacy Policy for details of their data handling.

3.3 License / nag counter

Stikkteller uses a WinRAR-style optional license. The app counts the cumulative number of completed matchboxes on your device using local storage. This counter is a single integer. It contains no personal data and never leaves your device.

4. AI processing (day complete message)

When you use all 12 matches in a day, Stikkteller may request a short, comforting message from our Cloudflare Worker, which forwards the request to xAI (the company behind the Grok AI model). The request contains no personal data, no match history, and no task text. Only a generic "day complete" prompt. The request is not logged at the Worker level. xAI may process the request according to their own terms and privacy policy. See xAI's Privacy Policy. If the request fails, a local fallback message is shown instead.

5. In-app purchases

If you choose to purchase a Stikkteller license, the transaction is handled entirely by Apple (App Store) or Google (Google Play). We do not process payments ourselves and do not receive your payment card details.

Purchase validation uses RevenueCat, a third-party service that receives a purchase receipt token (no personally identifying data is sent by us). See RevenueCat's Privacy Policy.

6. Children

Stikkteller does not knowingly collect any information from children under the age of 13 (or the applicable age of digital consent in your country). The app does not collect personal data from any user, making it broadly safe for all ages; however, it is not specifically directed at children.

7. Data retention and deletion

Because we do not store personal data, there is nothing to delete on our servers. The local match count and nag counter stored on your device can be cleared by uninstalling the app. Aggregate analytics records are not linked to you and cannot be individually deleted.

8. Your rights

Under GDPR, CCPA, and similar regulations you have rights regarding your personal data. Since Stikkteller does not collect or store personal data, most requests of this nature do not apply. If you have a privacy concern or question, contact us at contact@u-things.com and we will respond within 30 days.

9. Third-party services summary

10. Changes to this policy

If we materially change this policy, we will update the effective date above and, where appropriate, provide notice through the app. Continued use of Stikkteller after a policy update constitutes acceptance of the revised policy.
