Summary: Mahjonguinho is a Mahjong Solitaire game for kids: find pairs of matching tiles (faces, animals, cars and fruits) until the board is clear. It does not ask for sign-up, does not create an account, does not show ads, does not sell anything and has no server. PlayDude does not collect, receive or share personal data from players. What the game remembers (settings and progress) is stored only on the device itself.
1. Data that stays only on your device
The game stores some information in the device's local storage, only so you don't lose your choices from one match to the next:
- Preferences — chosen level (Little Ones, Adventurers or Challenge), tile collection, language, sounds, vibration and whether the Challenge timer is on.
- Progress — how many times each board shape was completed and the best time (only when the timer is on).
- Tutorial — whether Dude's explanation has already been seen, so it isn't always repeated.
This information is not sent to PlayDude or anyone else: there is no account, server or sync behind the game. It does not identify the child (there is no name, age, photo, e-mail or location) and it is gone when you clear the app's data or uninstall it.
2. What the game does not do
- It does not show ads and does not use the device's advertising ID.
- It has no in-app purchases.
- It does not ask for or store name, age, e-mail, photo, contacts or location.
- It has no chat, public profile, online leaderboard or links to social networks inside the play area.
- It does not use the camera, microphone or any special Android permission.
- It does not use analytics or tracking tools.
3. Google Play
The game is distributed through Google Play. Downloads, updates and store reviews are handled by Google, under the Google Privacy Policy. When it opens, the game may ask Google Play itself whether there is a newer version, to show "New version!" on screen; this check is done by the Play service on the device and sends no player data to PlayDude.
4. Children
Mahjonguinho was made for children aged 3 to 8 and also for older players. Since we collect no personal data, there is nothing to ask permission for. We recommend that parents and guardians supervise children's use of devices. This document follows the Brazilian General Data Protection Law (LGPD, Law 13.709/2018), in particular article 14, and the rules of the Google Play Families program.
5. Sounds and voice
The sound effects are generated by the device itself, and the lines of Dude, the mascot who teaches you to play, come pre-recorded inside the app. None of this uses the internet or the microphone.
6. Your rights and how to contact us
Since the game sends no data to PlayDude, we have no data of yours to show, correct or delete. To delete what stays on the device, use Android Settings → Apps → Mahjonguinho → Storage → Clear data, or uninstall the game. Privacy questions: contato@playdude.com.br.
7. Changes to this policy
If the game changes (for example, if one day it adds some service that handles data), this page will be updated before the new version reaches the store, with the new effective date at the top.
