The Crushing Abyss is a mobile game developed by Tinker Apps. Tinker Apps operates no servers of its own — your saved game lives on your device. We use a small number of Google services to understand how the game is played, to find out when it crashes, to offer optional cloud saves and achievements, and to show the Play Store rating card. Each of them is described below.
There is no advertising in this game. We do not sell your data, and we do not share it with anyone for advertising.
Four separate things, which are worth keeping apart:
We do not collect your name, email address, phone number, contacts, photos, precise location, or your device's advertising identifier.
| Service | Why it is there | Optional? |
|---|---|---|
| Google Firebase Analytics | Anonymous gameplay statistics, so we can see where dives get too hard and balance the game | Yes — Settings › Privacy |
| Google Firebase Crashlytics | Crash and error reports, so we can fix what breaks the game | Yes — Settings › Privacy |
| Google Play Games Services | Sign-in, achievements, cloud save | Yes — only if you sign in |
| Google Play In-App Review | Shows the Play Store rating card inside the game | Yes — you can dismiss it |
The game reports anonymous events to Google Firebase Analytics so we can see how the dive actually plays out across many runs. It is how we find the places where the dive is unfairly hard, and it is the only view we have of that.
What is recorded:
Firebase itself also records standard technical information: a randomly generated app-instance identifier, your device model and operating system version, the app version, language, and an approximate country derived from your IP address. Google does not retain the IP address itself.
What is not recorded: any personal identifier, your Google account, your Play Games profile, or your device's advertising ID. Advertising ID collection is explicitly disabled in the app, and the permission that would allow it is removed from the app at build time. None of this data is used for advertising or shared with advertisers.
Google acts as our data processor for this information and handles it under Firebase's data processing terms and Google's Privacy Policy.
When the game crashes, freezes on an unexpected error, or hits a bug in its own code, a diagnostic report is sent to Google Firebase Crashlytics. Without it a crash that only happens on one make of phone is invisible to us — the report is what makes it fixable.
What a report contains:
What a report does not contain: your name, email address, Google account, Play Games profile, advertising ID, or the contents of your saved game. We never attach an identifier of you as a person to a crash report.
Google acts as our data processor for crash reports, under the same Firebase data processing terms linked above.
The app optionally integrates with Google Play Games Services (GPGS) for sign-in, cloud saves, and achievement tracking. If you do not sign in, no personal data is transmitted off your device.
If you do sign in, Google Play Games Services independently collects the following for app functionality purposes:
Tinker Apps accesses Play Games data only to provide sign-in, cloud saves, and achievements, and does not store it on its own servers or use it for any other purpose. Google Play Games Services operates as an independent data controller under Google's Privacy Policy.
After you have played for a while, the game may show Google Play's native rating card once. This is handled entirely by the Google Play In-App Review API: the card is drawn by Google Play, your rating goes to Google, and the game receives no data back — not even whether the card was shown or whether you rated it. Any review you submit is published under Google's Privacy Policy and the Play Store's review policies.
Your saved game stays on your device until you delete it or uninstall the app. Cloud saves are kept by Google Play Games Services until you delete them from your Play Games profile.
Anonymous analytics events are held by Google for the retention period configured in our Firebase project, after which Google deletes them automatically. Aggregated, non-identifying summaries (for example "the median dive ends at 3,400m") may be kept indefinitely, as they cannot be traced back to any device.
Crash reports are kept by Firebase Crashlytics for up to 90 days and are then deleted automatically. The aggregate counts derived from them — how many devices hit a given crash, and on which app versions — are kept while that crash is still open, so we can tell whether a fix worked.
We do not store your data on our infrastructure, so there is nothing for us to delete directly.
If you are in the EEA, the UK or Switzerland, you have the right to access, correct, delete, restrict or object to the processing of your personal data, and to data portability. Our legal basis for the anonymous gameplay statistics is our legitimate interest in understanding and balancing the game, and for the crash reports our legitimate interest in keeping the game working on the devices people actually play it on; you can withdraw from both at any time using the in-game toggle, with no effect on the game itself. Play Games Services data is processed on the basis of your consent, given when you sign in.
If you are in California or another US state with a privacy law, you have the right to know what is collected, to delete it, and to opt out of any sale or sharing. We do not sell or share personal information, and we do not use it for cross-context behavioural advertising.
Most of these rights can be exercised directly in the game or in your Google Account settings. For anything else, email us — see Contact.
The Crushing Abyss is not directed to children under 13, and we do not knowingly collect personal information from them. The analytics described above are not used to build advertising profiles of anyone. If you believe a child has provided us with personal information, contact us and we will delete it.
Google processes the data described in this policy on servers located in the United States and other countries. Where data is transferred out of the EEA, the UK or Switzerland, Google relies on the European Commission's Standard Contractual Clauses and equivalent safeguards, as set out in its data processing terms.
We may update this policy from time to time. Any changes will be posted at this URL with an updated effective date. Continued use of the app after changes are posted constitutes acceptance of the updated policy.
