Your privacy in Stamp Studio
Last updated: 9 November 2026
JL Prime develops Stamp Studio, a picture puzzle game for children and grown-ups. This policy covers the iPhone app (com.jlprime.stampStudio), the Android app (com.jlprime.stamp_studio) and the game's pages on jlprime.com.sg. In short: we don't ask for names, emails or accounts, and the game's ads are set up for children. Contact support@jlprime.com.sg with privacy questions.
What we don't collect
Stamp Studio has no accounts, no sign-in, no chat and no in-app purchases. We never ask for a name, email address, photo, contacts or exact location, and we don't sell anyone's information.
Game progress stays on your device
Your stars, finished pictures, postcards and settings (such as sound and ink marks) are saved only on the device, in local app storage. They are not sent to JL Prime. There is no cloud save, so we cannot restore progress on a new device. Your operating system may include app data in its own backups.
Ads (Google AdMob and Unity Ads)
There are no ads between pictures in the first world. After that, a short ad may play between some pictures, and players can choose to watch a video for an extra hint (the first hint on every picture is free). There are no banner ads and no ads in the middle of a puzzle.
Ads come from Google AdMob. Every ad request is marked as directed to children and limited to family-friendly (G-rated) ads, so ads are not personalised and are not based on what the player does in other apps. The game does not use the device's advertising ID and does not ask to track the player across apps.
To show and count ads and to prevent fraud, Google's ad software may process device and app information such as an app installation identifier, the device type and operating system, an approximate location worked out from the IP address, and how ads were viewed. Read Google's ad SDK disclosure, how Google uses information from apps that use its services and Google's Privacy Policy.
Some ads are supplied by Unity Ads, which Google AdMob asks for an ad on our behalf. For Stamp Studio, Unity Ads is set up for Google's Designed for Families programme: it shows only contextual, family-friendly ads that are not based on what the player does, and it blocks ads rated for ages 13 and over. To show and count ads and to prevent fraud, Unity may process device and app information such as the device type and operating system, an approximate location worked out from the IP address, and how ads were viewed. Read Unity's privacy policy for game players.
Crash reports (Firebase Crashlytics)
If the game crashes, a crash report is sent to Google Firebase Crashlytics so we can fix the problem. A report contains technical details only: what went wrong, the device model, the operating system version and an installation identifier. It contains no name or contact details. Stamp Studio does not use Firebase Analytics. See Firebase's privacy information.
Ratings
After some pictures the game may ask the App Store or Google Play to show its own "rate this app" box. That box is run by Apple or Google; JL Prime does not see who rated or how.
This website
The JL Prime website (jlprime.com.sg) is hosted by Netlify. Netlify processes incoming IP addresses to deliver the pages, detect abuse and provide basic usage information; see Netlify's privacy policy. The pages contain no analytics scripts, advertising, sign-in forms or tracking cookies added by JL Prime. Fonts are loaded from Google Fonts, which receives your IP address when a page loads. Game videos load from YouTube only after you tap play.
When you contact support
If you email us, we receive your email address and anything you send, such as a description, device details or screenshots. We use this to respond and investigate the issue. Please do not send passwords, payment information or unnecessary personal details. We keep support correspondence as needed to handle the request and relevant business or legal obligations.
Children
Stamp Studio is made to be safe for children. We don't knowingly collect personal information from children, and the game's ads and crash reports are set up as described above. If you are a parent or guardian and think information about your child has been collected, please contact us and we will delete it.
Your choices and deletion
You can reset the game's progress in the game's Settings, or delete the app to remove everything it stored on the device. Reports already sent to Google are kept and deleted according to Google's policies. Contact us to request access, correction or deletion of information you sent to support. We cannot remotely erase a device-only save or restore one that has been deleted.
Changes and contact
We will update this page when the app's data practices change. The date above identifies this version. For questions or privacy requests, email support@jlprime.com.sg.
