In one sentence

Mahjong Axions is played with no account, no sign-up and offline. Your progress stays on your device. We sell no data, and nothing in this game is ever paid for — in any form.

1. What stays on your device, and never leaves it

The game saves your progress to a file in the app's private storage on your device. It holds:

• your level, completed levels and coins;
• your streaks — consecutive days, consecutive wins — and your personal bests;
• your settings: sound, music, vibration, language, accessibility options;
• a random identifier generated by the game, containing nothing about you: no name, no address, no device identifier. It exists to tell players apart if leaderboards are on;
• your advertising choice, so we never ask you twice.

This file is not sent to our servers. Uninstalling the game erases it.

You can also erase it at any time from within the game: Settings → Delete my data. Deletion is immediate and permanent; we cannot restore it, because we never held a copy.

2. What we do not collect

We never request, read or store any of the following:

• name, postal address, email address, phone number;
• precise location;
• contacts, photos, microphone, camera, files;
• payment details — there are no purchases in this game, so there is nothing to pay with.

The game requests no system permission beyond those needed to display the videos you choose to watch.

3. Advertising

No advertising is forced on you. There are no banners, no interstitials, and no ads between games. The only videos in this game are the ones you choose to watch, by tapping a button that states the reward up front.

They are served by Google AdMob. To display them, AdMob may process your device's advertising identifier and technical information (model, system, language, country, approximate IP address).

• Google's policy: https://policies.google.com/privacy
• Your Google ad settings: https://adssettings.google.com

Your choice. If you live in the European Economic Area, the United Kingdom or Switzerland, a form asks for your consent the first time it applies. You can change it at any time: Settings → Ad preferences.

Declining removes no reward: videos grant exactly the same thing, they are simply less targeted. The game states this commitment itself, in its "Our promise" screen.

4. Analytics

To understand what works in the game and what blocks players, we record gameplay events. They describe actions, never people:

• level started, completed, abandoned or lost, and how long it took;
• helpers used, peak tray occupancy, plaques earned;
• videos requested, shown, completed or failed;
• app opens, and league rank if leaderboards are on.

These events are attached to the random identifier in §1, never to your identity. We cannot trace an event back to a person, and we do not try.

We run no targeted advertising from this data, and we do not sell it.

Tools. These events are processed by Google Firebase Analytics, and crashes by Firebase Crashlytics, which then receives the device model, system version and the technical state of the app at the time of the crash — never the content of your game. Identifier-level analytics data is kept for two months at Google; only aggregated statistics remain afterwards. Google's policy: https://policies.google.com/privacy.

5. Children

Mahjong Axions is not directed to children. It contains rewarded advertising and is rated for ages 12 and over. We do not knowingly collect data from a child.

6. Your rights

Because the game stores your data only on your device, you control it directly: Settings → Delete my data erases everything, immediately.

If leaderboards are active and you want the data tied to your identifier deleted, write to the address above and include that identifier, which the game shows in Settings → About. We reply within thirty days.

Depending on your country you have rights of access, rectification, erasure, objection and portability (GDPR in Europe, the Digital Personal Data Protection Act in India, and equivalents elsewhere). The contact address above is how to exercise them, and you may also contact your country's data protection authority.

7. Changes

Any change to this policy will be published on this page, with its date. If a change widens what we collect, it will be announced inside the game before it takes effect — not only here.
