Privacy Policy

In short

Len Dee does not collect your name, email, phone number, or any identifying information. There is no sign-up and no in-app purchases. All scores and statistics stay on your phone. The app shows ads from Google AdMob, which uses your device Advertising ID — see Advertising below.

Stored on your device

• Daily results for the 5 games (score, time, mistakes, stars)
• Your streak and overall statistics
• Settings such as language, Thai numerals, and notifications

This data never leaves your device and is removed when you uninstall the app or clear its data.

Sharing results

When you tap share, the app creates a result card or text and hands it to the app you choose (for example LINE or Facebook). Nothing is sent to our servers; the receiving app follows its own policy.

Notifications

If you enable notifications, reminders are scheduled locally on your device to tell you that new puzzles are ready. We do not send push messages from a server, and you can turn them off any time in Settings.

Internet

All 5 games work offline. The app uses the internet to load the fonts it displays and to load ads. Without a connection, ads simply do not appear and the games still work.

Advertising

Len Dee shows ads through Google AdMob so the game can stay free. Ads never appear while you are playing a puzzle — they appear on the home screen and after you finish all 5 games for the day. Rewarded ads are shown only when you choose to watch one.

Google serves these ads and may collect and use your device Advertising ID, approximate IP-based location, and limited app-usage signals to select ads, measure them, and prevent fraud. We do not receive information that identifies you from the ad system, and we do not send your data to advertisers ourselves. See policies.google.com/technologies/partner-sites.

Where the law requires it (for example in the EU and UK), the app asks for your consent before showing personalised ads, and you can change your mind later. If you decline, ads still appear but are non-personalised.

You can reset or delete your Advertising ID yourself in Settings → Privacy → Ads on your device (menu names vary by model).

What we do not do

• No sign-up or login.
• No in-app purchases.
• No ads while you are in the middle of a puzzle.
• No access to contacts, location, camera, or microphone.
• We never sell or share your data with third parties.

Children

This app is suitable for all ages, contains no violent or inappropriate content, and collects no personal data from any user, including children.

Deleting your data

Because we hold no data on servers, uninstalling the app or clearing its app data removes everything.

Future changes

If we later add ads, online rankings, or cloud backup, we will update this page and tell you in the app before those features go live.
