Privacy Policy
1. Who we are
Dovetail Block Puzzle is a mobile puzzle game published by ZUPON Studio for Android, distributed on Google Play under the package name com.zuponstudio.dovetail. This policy explains what information is collected when you play, and how it's used.
2. Information we collect
Dovetail Block Puzzle does not ask you to create an account, and we — ZUPON Studio — do not directly collect your name, email address, contacts, photos, or any other personal information. Your game progress, scores, and settings are stored only on your own device and are not transmitted to us.
The app does include one third-party service, Google AdMob, which serves the in-game ads that keep Dovetail Block Puzzle free to play. AdMob collects a limited set of data on its own behalf, described next.
3. Advertising & Google AdMob
Dovetail Block Puzzle shows banner, interstitial, and optional rewarded ads through Google AdMob (part of Google Ireland Limited / Google LLC). To select and deliver ads, and to measure their performance, Google's SDK collects data along these lines:
| Data type | Purpose |
|---|---|
| Advertising ID and other device identifiers | Ad selection, frequency capping, and fraud prevention |
| Approximate, IP‑based location | General ad relevance (not precise GPS location) |
| App interaction data (impressions, clicks, ad performance) | Measuring and improving ad delivery |
| Basic device and network information | Ad rendering and diagnostics |
This data is collected and processed by Google, not by ZUPON Studio directly, and is handled under Google's Privacy Policy. You can read more about how Google uses information from apps that use its services at policies.google.com/technologies/partner-sites.
Dovetail Block Puzzle also offers an optional in-app purchase, "Remove Ads," which turns off ad serving — and the associated AdMob data collection — for that device going forward. Purchases are processed by Google Play; we do not receive or store your payment details.
4. Your choices
- Reset or limit your advertising ID in your device settings under Google Settings → Ads, or Settings → Privacy → Ads on newer Android versions.
- Opt out of personalized ads for your Google account at adssettings.google.com.
- Remove ads entirely within the app via the "Remove Ads" purchase in Settings.
5. Children's privacy
Dovetail Block Puzzle is designed for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us using the details below so we can address it.
6. Data security
Because Dovetail Block Puzzle does not collect or store personal data on our own servers, there is no ZUPON Studio–held account database to protect. Data handled by Google AdMob is transmitted using industry-standard encryption in transit, governed by Google's own security practices.
7. Data retention
We do not retain any player data, since none is collected by us. Retention of advertising and device-identifier data collected by Google AdMob is governed by Google's own retention policies, described in its Privacy Policy linked above.
8. Changes to this policy
We may update this policy from time to time — for example, if we add new features or third-party services. The effective date at the top of this page will always reflect the most recent revision. Material changes will be reflected here before they take effect.
