Privacy Policy
Last updated: 2026-06-19
This policy describes what data Chronology ("the app") collects and how it is used. It reflects the app as built; update it whenever data handling changes, and keep it consistent with the store privacy questionnaires.
Summary
Chronology is a free, ad-supported card game you play on your device. We do not ask for your name, email, phone number, or location, and this version has no online account and no game server — the app is fully playable offline. To keep it free, it shows ads through Google AdMob, which collects certain device and usage data to deliver and measure those ads (details below). Where required (for example in the EEA and UK), the app asks for your consent first.
Data kept on your device only
The following stay on your device and are not sent to us:
| Data | What it is |
|---|---|
| Display name | Defaults to "Player"; you may change it. Used only to label your local profile. |
| Language | Your selected UI language. |
| Statistics & Time-Trial history | Your scores and results, used to show your own stats. |
| Settings | Local app preferences. |
This data is removed when you uninstall the app or clear its storage.
Advertising (Google AdMob)
We use Google AdMob to show ads. To deliver and measure ads, Google may collect and process device identifiers (including the advertising ID), IP address, coarse location inferred from IP, and ad/app interaction events. Google acts as an independent controller of this data under its own policies:
- Google Privacy Policy: https://policies.google.com/privacy
- How Google uses data from apps that use its services: https://policies.google.com/technologies/partner-sites
We (the developer) do not receive your name, email, phone number, or precise location through ads.
Your choices
- In the EEA, UK, and other regions that require it, the app shows a consent prompt (Google's User Messaging Platform) on first launch, where you choose whether ads are personalised.
- You can reset or limit ad personalisation at any time in your device settings (Android: Settings → Google → Ads).
In-app purchases
The app offers optional one-time purchases (remove-ads and content packs). Payment is handled entirely by the store operator — Google Play on Android, the App Store on iOS. We do not receive or store your card details or bank information; the app only receives an anonymous token confirming a successful purchase, used to unlock what you bought. See the store operators' privacy policies (Google Play / Apple) for how they process payment data.
Crash diagnostics
The app integrates Sentry to capture anonymous crash and error reports (device model, OS version, app state at the time of the crash) so we can fix bugs. It collects no name, email, or precise location. It is disabled in the current release — no crash data is collected unless we enable it in a future build, in which case this policy and the "Last updated" date will be updated.
What we do not collect
We do not collect or store on our own servers: your real name, email, phone number, contacts, precise location, photos, advertising identifiers, or device sensor data. This version has no login and no game server of our own. The data that leaves your device is the advertising data handled by Google described above; purchases are processed by the store operators, not us.
Children's privacy
Chronology is intended for a general audience and does not knowingly collect personal information from children. Because the app shows ads, the app's store age rating and target-audience settings determine how ads are served; ad requests are configured to match that rating. Parents and guardians should be aware that Google's ad services process device data as described above.
Data retention and deletion
- On-device data (display name, settings, statistics, history) is removed when you uninstall the app or clear its storage.
- Advertising data is held by Google under its own retention policies; manage it through your device's ad settings and your Google account.
Online features (coming later)
A future update will add optional online multiplayer — ranked matches and leaderboards. When it ships, this policy will be updated to describe the data those features use, along with the "Last updated" date.
Changes to this policy
If data handling changes, we will update this document and the "Last updated" date, and reflect the change in the app store listings.
