Privacy Policy

Last updated: 4 October 2026

The short version

Detective Grid has no account, no sign-up and no login, and your game progress never leaves your device. On this website nothing is collected. In the iPhone and iPad app, two things can send data off your device: ads (served by Google AdMob) and anonymous crash reports (sent to Sentry). Both are described below.

What is stored on your device

The game saves your progress — which cards you solved, your time, your mistakes and your streak — in your browser's local storage or, in the app, in the app's own sandbox. This data never leaves your device, we cannot read it, and clearing your browser data (or deleting the app) removes it permanently.

Advertising (app only)

The app shows ads served by Google AdMob. When an ad is requested, the AdMob SDK collects data on Google's behalf, which may include device identifiers, coarse location derived from your IP address, device and app information, and data about the ads you see. This data is used to deliver and measure advertising. On first launch the app asks for App Tracking Transparency permission; if you decline, ads are not personalised across other apps and websites, and the game works the same. See how Google uses data from partner apps.

Crash reports (app only)

To find and fix bugs, the app uses Sentry (Functional Software, Inc.) for crash and error reporting. If the app crashes or hits an error, a report is sent that may include the error itself and where it happened, your device model, iOS version and app version, and a random installation ID. Crash reports are not linked to your identity, are not used for advertising or tracking, and contain no names, e-mail addresses or contact details. They are stored on Sentry's servers in the European Union. See the Sentry Privacy Policy.

What we do not do

• We do not ask for your name, e-mail address, phone number or precise location.
• We do not run our own analytics or build profiles of you.
• We do not sell your data.

Children

The game is suitable for a general audience but is not directed at children under 13, and we do not knowingly collect personal information from them.

Your rights

We hold no personal data about you on any server of ours, so there is nothing for us to export, correct or delete on request. You can decline tracking permission at first launch or change it later in iOS Settings, and deleting the app removes all data it stored on your device.
