Tesslide Privacy Policy

Effective date: 2026-11-02

Tesslide is a sliding picture puzzle game: you turn one of the built-in pictures, or a photo you choose, into a 3×3 to 8×8 slide puzzle, then see your best times and the pictures you completed. It also has reminders and a home screen widget (the "app"). It is provided by DDJ A1 ("we", "us"). This policy explains what data the app handles and how. Tesslide has no account system and we do not run a server for it.

Photos you choose

When you pick a photo from your gallery (through Android's photo picker) or take one with your camera app, Tesslide makes a smaller copy of that one photo inside the app's private storage so you can resume the puzzle and see it in your completed gallery. The app only sees the photos you pick; it cannot browse the rest of your gallery. Your photos are processed on your device and are not uploaded to us. You can delete them by removing the puzzle from your gallery in the app or by uninstalling the app.

Data stored on your device

The puzzle you are playing (picture, board size, tile positions, moves and time), your results per board size (puzzles completed, best time, fewest moves), your completed gallery and your settings (tile numbers, animation speed, sound, theme, reminders) are stored only on your device. They are not sent to us. Uninstalling the app deletes this data from your device. If device backup is turned on, Android's standard app backup may include this data in your own Google account backup. That backup is controlled by you and Google, not by us.

Sharing

When you use Share, the app creates a result image (your completed picture with the board size, time and moves) and hands it to the app you pick in the Android share sheet. The app does not upload anything by itself. If the puzzle uses your own photo, you see the image before you choose where to share it.

Permissions the app asks for and why

• Notifications (optional). Used for a light reminder to take a puzzle break or finish an unfinished puzzle. You can decline and every feature still works.
• Run at startup. Lets reminders and the home screen widget come back after your phone restarts or the time zone changes.
• Vibration. A light tap when tiles move or a puzzle is completed, if you turn vibration on.
• Internet access and the advertising identifier (AD_ID). Used only by the advertising components described below. Puzzles work offline.

The app does not request the camera permission (taking a photo opens your own camera app), storage or media permissions, the microphone, location or your contacts.

Information collected automatically

When you use the app, third-party SDKs used for advertising may collect some information automatically, including:

• Your device's Internet Protocol (IP) address, which may be used to estimate your approximate (general) location
• Device or other identifiers, such as your device's advertising identifier (Advertising ID) and app set ID
• App interactions, such as session time, screens viewed, and ad views and taps
• Crash logs and diagnostic information, such as your device's operating system and model, and ad performance data

The advertising SDK collects this information and shares it with Google (AdMob) and its advertising partners for advertising, analytics, fraud prevention, security and compliance. It is encrypted in transit. The app itself does not send your photos or game data off your device, and we do not link the advertising data to them.

Advertising

The app shows advertisements from Google AdMob:

• a banner at the bottom of the screens
• an ad when the app starts from the launcher
• full-screen ads only between puzzles: when you tap Next puzzle after viewing a completed picture, and when you start a new puzzle from the home screen
• an ad in the exit dialog
• optional video ads you can choose to watch: to refill hints, or from Settings to see fewer ads for 24 hours

A full-screen ad never appears while you are solving a puzzle, when you use a hint, while you are looking at your completed picture, or when you resume a puzzle. To serve ads, AdMob and its partners may access your device's Advertising ID and the information described above. In the European Economic Area (EEA), the United Kingdom and other regions where required, the app shows a consent form through Google's User Messaging Platform (UMP) before personalized advertising data is used. If you decline, you are shown non-personalized ads instead. You can reset or limit ad personalization at any time in your device settings (Settings → Google → Ads), and you can change your consent choice from the app's Settings screen.

For more information on how Google uses data when you use partners' apps, see https://policies.google.com/technologies/partner-sites.

Children

Tesslide is a general-audience puzzle game and is not directed to children under 13. We do not knowingly collect personal information from children.

Your rights

Your photos and game data exist only on your device, so you control them directly, and uninstalling the app removes everything the app stored. Depending on where you live (for example under the GDPR in the EEA/UK or the CCPA in California), you may also have rights over data processed by advertising SDKs. You can exercise your ad choices through the consent form and your device's ad settings described above.

Changes

We may update this policy. Material changes will be reflected on this page with a new effective date.
