Privacy Policy
Zolku is a puzzle game. It has no accounts, no sign-in and no server that stores anything about you. This page describes the little data that does move, almost all of which is the advertising that keeps the game free.
What Zolku does not collect
- No name, email address, phone number or contacts.
- No location.
- No photos, files or anything else on your device.
- No account of any kind — your solved count and streak live only on your own device and are lost if you uninstall the app.
Advertising
Zolku shows an occasional full-screen ad between puzzles, served by Google AdMob. To choose and measure those ads, Google's software receives:
- Your device's advertising identifier — a resettable ID that Android and iOS provide for this purpose.
- Basic device and network information: model, operating system version, language, coarse region and IP address.
- Whether an ad was shown, viewed or tapped.
This data goes to Google, not to us. Their handling of it is covered by Google's policy for partner sites and apps.
Your choices
- Limit ad tracking. Android: Settings → Google → Ads → "Delete advertising ID". iOS: Settings → Privacy & Security → Tracking. Ads still appear, but they stop being personalised.
- In the EU, UK and Switzerland you are asked for consent before personalised ads are requested, and you can decline.
- Uninstalling removes everything the app kept on your device.
Children
Zolku is not directed at children under 13 and we do not knowingly collect anything from them.
Crash reports
When the app crashes, a report is sent to Sentry so the fault can be found and fixed. A report contains what went wrong and where — not who it happened to:
- The error and the stack trace that produced it.
- Device model, operating system version and app version.
- A short trail of what the app was doing beforehand.
Personal identifiers are deliberately switched off, so reports carry no advertising identifier and no IP address, and there is no account for them to be attached to. Sentry's handling is covered by Sentry's privacy policy.
Updates to the app
Zolku checks for updates when it starts. That request tells our update provider (Expo) the app version and platform so it can answer with the right bundle. It carries no identifier for you.
Changes to this policy
If this policy changes, the date at the top changes with it. Material changes will be noted in the app.
