Privacy Policy

Last updated: 22 September 2026

This policy explains what information the Jade Wall mobile game ("the app") uses and why. Jade Wall is published by Dihardja Software ("we", "us").

In short

You don't need an account, and we don't ask for your name, email or phone number to play.
Your games, records, settings and photo are stored on your device only.
The app has no ads, no analytics and no tracking.
The app only connects to the internet to deliver updates, confirm a Jade Wall Pro purchase, and send feedback if you choose to.

Information stored on your device

The app saves these on your device, and they never leave it unless you export them yourself:

Your games, records and match history
Your settings, such as game speed, music and difficulty
Your player name and the photo you put on your seat

You can delete this data at any time by clearing the app's data in your device settings or by uninstalling the app. If you use the backup feature, the app creates a file that you choose where to save or share. That file is then under your control.

Camera and photos

If you choose to put your photo on your seat, the app asks for permission to use your camera, or lets you pick an image from your gallery. The photo is processed and stored on your device only. We never receive it. You can refuse or withdraw this permission at any time in your device settings, and the rest of the game still works.

Information sent over the internet

The app connects to our server (apios.dihardjasoftware.com) in these cases only:

App updates. To check for and download a newer version of the game's content, the app sends technical information: the app's ID and version, your device platform and operating system version, the update system's own version, whether the device is an emulator, whether it is a production build, which store installed the app, and a random identifier created by the update system. This identifier is not linked to your name or any account. We keep these technical logs only as long as we need them to run and troubleshoot the update service.
Jade Wall Pro purchases. When you buy or restore Jade Wall Pro, the app sends the purchase receipt issued by Google Play or the App Store (the product, your platform and a purchase token) so we can confirm the purchase is genuine. We do not receive your name, email or payment details; those stay with Google or Apple. We keep the record of a purchase for as long as it is needed to confirm your access to Jade Wall Pro.
Feedback. If you send feedback from inside the app, we receive your message, the feedback type, the app version, and your name and email only if you choose to enter them. We use this to reply and to improve the app, and we keep it only as long as we need it for that. If in-app feedback is not available in your version, the app opens your device's share menu instead, and nothing is sent to us.

We do not sell, rent or share this information with third parties for advertising or any other purpose.

Google Play and the App Store

Purchases and payments are handled by Google Play or the Apple App Store under their own privacy policies. These stores may also collect information such as install statistics and crash reports, which we only see in aggregate form, if at all. Rating prompts use your device's built-in review dialog.

Children

Jade Wall does not knowingly collect personal information from children. The app works without any account or personal details.

Changes to this policy

If we change how the app handles information, we will update this page and its "Last updated" date before that version of the app is released.

Questions about this policy go to the same place as any other support question: see Contact.

Terms of Service

Last updated: 22 September 2026

These terms apply to your use of the Jade Wall mobile game ("the app"), published by Dihardja Software ("we", "us"). By downloading or using the app, you agree to these terms. If you don't agree, please don't use the app.

1. Using the app

We give you a personal, non-exclusive, non-transferable right to use the app on devices you own or control, for your own entertainment. You may not copy, modify, resell or redistribute the app, or try to extract its source code, except where the law allows it.

2. Entertainment only, no real money

Jade Wall is a game of skill and chance played against computer opponents for fun. It involves no real money gambling, no cash prizes, and no way to win or exchange anything of value. Points and records in the app have no monetary value.

3. Jade Wall Pro

Jade Wall Pro is an optional one-time purchase that unlocks extra content, currently the full 16 hand game, three-player games and additional tables. The free version stays fully playable without it.
Purchases are made through Google Play or the Apple App Store and are subject to their terms. The price is shown by the store before you buy.
Pro is tied to the store account you bought it with. You can restore it on another device using the same store account and the Restore purchase button. A purchase on Google Play does not unlock Pro on iOS, and a purchase on the App Store does not unlock Pro on Android.
Refunds are handled by Google Play or Apple under their own refund policies. We cannot issue refunds directly.
If we ever remove a Pro feature, we will not take away anything you have already paid for without offering a reasonable alternative.

4. Your data and backups

Your games, records, settings and photo are stored on your device, as described in our Privacy Policy. We don't keep a copy. If you uninstall the app, clear its data or lose your device without a backup, that data cannot be recovered. You can create a backup file from inside the app.

5. Updates

We may update the app to fix problems, improve it or add features. Some updates download automatically. We may also change or stop offering features of the free version.

6. Feedback

If you send us feedback or ideas, you allow us to use them to improve the app, without any obligation to you.

7. Our content

The app, including its artwork, table designs, sounds, music and software, belongs to us or our licensors and is protected by law. These terms don't give you any rights to it beyond using the app as described here.

8. No warranty

We work hard to make the app reliable, but it is provided "as is". To the extent the law allows, we don't guarantee that it will always be available, error free, or suitable for a particular purpose.

9. Limitation of liability

To the extent the law allows, we are not liable for indirect or consequential losses, or for loss of data, arising from your use of the app. Our total liability to you is limited to the amount you paid for the app and Jade Wall Pro. Nothing in these terms limits rights you have under consumer protection law that cannot be limited.

10. Changes to these terms

We may update these terms. We will post the new version on this page with a new "Last updated" date. If you keep using the app after that, you accept the updated terms.

11. Governing law

These terms are governed by the laws of the Republic of Indonesia, where Dihardja Software is based.

12. Contact

See Contact. We answer in English or Bahasa Indonesia.

Purchases and refunds
