Inferlo Privacy Policy

Effective date: 2026-11-05

Inferlo ("the app") is a free logic grid puzzle game provided by DDJ B1 ("we", "us"). You read short clues and mark a grid to work out who goes with what, with a new daily puzzle and unlimited puzzles at four levels. It has no account system, no login, no subscription and no server operated by us. Puzzles are generated on your device and the game works offline.

Your data

Your puzzle progress, solve times, hint counts, daily streak, statistics and settings are stored locally on your device.

• The app itself does not upload this data, and we never receive it.
• The advertising SDK described below may collect information as explained in that section. Your puzzle progress and statistics are not passed to the advertising SDK.
• If you use "Share", a short text summary (for example level, time and hints) goes only to the app you choose through Android's share sheet.
• Android's standard app backup may include app data in your own Google account backup if you have device backup enabled; that backup is controlled by you and Google, not by us.

Permissions

• Notifications — for an optional daily puzzle reminder. You can decline or turn it off; everything else keeps working.
• Run at startup — to restore reminders after the phone restarts or the time zone changes.
• Vibration — for reminders, if you turn it on.
• Internet / network state / advertising ID — used by the advertising SDK described below.

Inferlo does not request location, contacts, camera, microphone, phone call, SMS, calendar or photo library permissions.

Advertising and information collected automatically

The app displays advertisements provided by Google AdMob inside the app only (never in notifications or in the widget). Full-screen ads are not shown while you are solving a puzzle; they may appear when you move on to the next puzzle. Ads are limited to content rated for general audiences. To serve and measure ads and to prevent fraud, the AdMob SDK may collect and share with Google information such as your device's advertising identifier and other device identifiers, approximate location derived from your IP address, app interactions (for example ad views and taps), crash logs and diagnostics. This data is shared with Google as a third party for advertising, analytics and fraud prevention purposes. For more information see https://policies.google.com/technologies/partner-sites.

For users in the European Economic Area (EEA), the United Kingdom and other regions where required, the app presents a consent form via Google's User Messaging Platform (UMP) before personalized advertising data is used; if you decline, non-personalized ads are shown. You can change your choice from the app's Settings screen ("Ad privacy settings") and reset or limit ad personalization in your device settings.

Children

The app is not directed to children under 13, and we do not knowingly collect personal information from children.

Your rights

Your app data exists only on your device and in backups you control; uninstalling the app removes the app's own copies. You can clear an unfinished puzzle inside the app at any time. Depending on your region (e.g. GDPR, CCPA), you may have rights regarding data processed by the advertising SDK; you can exercise ad-related choices through the consent form and your device's ad settings.

Changes to this policy

We may update this policy from time to time. Changes will be posted on this page with an updated effective date.
