1. What Walk & Build World is

Walk & Build World is an Android game that turns the user's real daily step count into in-game currency (Briksteps), which a crew of builders uses to construct famous places in 3D. Package name: com.pacior.walkbuild3d2.

2. What data the app processes

Step count — daily step totals read from Health Connect (only the READ_STEPS permission),
game progress — Briksteps, buildings and modules placed, unlocked places, souvenirs and stories, upgrades,
settings — game language, sound, music and vibration, consent choices,
optional anonymous statistics and crash reports (section 4.3).

The app does not request location, contacts, camera, microphone or any health data other than step count, and it does not read health data in the background.

3. Where data is stored

Daily step totals and game progress are stored locally on the user's device in the app's storage. Step counts are used only to award Briksteps and to show the user's own activity charts.

4. When data leaves the device

4.1. Health Connect

Step counts are read on the device through Android Health Connect. The app does not write any data to Health Connect. Access can be granted or revoked at any time in Health Connect settings; refusing access does not block the game.

4.2. Backup in Google Play Games (Saved Games)

The game backs up its save file (game progress, settings and daily step totals) to Saved Games in the user's own Google Play Games account: one automatic backup refreshed once a day and up to 5 backups made on request. Signing in to Google Play Games usually happens automatically. The game shows the player's Play Games display name in Settings; it does not send it anywhere. Saved Games are stored by Google in the user's Google account and the developer has no access to them. Backups can be managed or deleted in the Google Play Games app or in the Google Account settings.

Older backups on Google Drive. Versions of the game released before Google Play Games backups saved copies to a "Walk & Build World" folder on the user's Google Drive (scope drive.file, which lets the app see only files it created itself). The game now only reads those copies once, to move them to Google Play Games; it no longer writes to Google Drive and does not delete the old files. The folder can be deleted from Google Drive at any time, and Drive access can be revoked in the Google Account settings.

4.3. Anonymous statistics and crash reports (Google Firebase)

Statistics (Firebase Analytics) are sent only if the user agrees in the game; the choice can be changed in Settings at any time. They include game events (for example: building or place completed, place entered, language changed), game language, phone language, app version and device information (model, Android version), together with an app instance identifier. They do not include the user's name, email, step counts or precise location. The advertising ID is not collected.

Crash reports (Firebase Crashlytics) are on by default and can be turned off in Settings. When the app crashes they send technical details: stack trace, app version, device model, Android version and an installation identifier.

This data is processed by Google as a service provider and encrypted in transit (HTTPS). Details: Firebase privacy information and the Google Privacy Policy.

4.4. Optional rewarded ads (Google AdMob)

The game can show a video ad only when the player chooses to watch one in exchange for Briksteps; ads never appear on their own. Ads are provided by Google AdMob. Ads are non-personalised and the app does not use the advertising ID (the AD_ID permission is removed). To serve an ad, measure it and prevent fraud, the Google Mobile Ads SDK may process the IP address, device and app information (model, Android version, language, app version) and ad interactions (for example, whether the ad was watched to the end).

In the European Economic Area, the United Kingdom and Switzerland the game asks for consent with the Google consent form before the first ad; the choice can be changed at any time in Settings → Ad privacy. Details: How Google uses information from sites or apps that use its services.

5. Permissions

Health Connect — read steps (READ_STEPS) — to turn steps into Briksteps.
Internet — for backups in Google Play Games, moving old backups from Google Drive, statistics, crash reports and optional rewarded ads.

6. Ads, purchases and accounts

The game is free and has no in-app purchases. It shows ads only when the player chooses to watch one for a reward (see 4.4).
No separate account is needed. Backups use the player's Google Play Games account; Google Drive access is used only to move old backups.
Data is not sold. Apart from the ad requests described in 4.4, no data is shared with third parties for advertising.

7. Children

The game is intended for users aged 13 and over and does not knowingly collect personal data from children.

8. How to delete data

Uninstalling the app (or clearing its storage) removes all data stored on the device.
Backups can be deleted in Google Play Games (Saved Games) or the Google Account settings; old copies can be deleted from Google Drive (folder "Walk & Build World").
Statistics can be turned off in Settings; to request deletion of statistics or crash data already sent, email the address below.
Step access can be revoked in Health Connect settings.
