Privacy Policy — GRAVEWALL
Version 1.0 — effective from 14 November 2026. This policy covers the game GRAVEWALL on Android and on Windows, in every store where it is offered.
In short: the game does not collect, send or share any personal data. It has no ads, no in-game purchases, no accounts and no chat, and it does not use the camera, the microphone, contacts or location. Your progress and settings are saved only on your own device, and you can delete them at any time.
1. Who is responsible
The game is made and published by Valter Joziel — Valtora Games. Contact for any privacy question: suporte@valtorastudio.com.
2. What the game keeps on your device (and never sends)
| What | Where | Why |
|---|---|---|
| Progress (maps finished, best wave, zombies defeated, achievements) and game options (language, volumes, graphics quality, FPS limit, camera speed, difficulty) | Android: the game's private storage, which only the game can read. Windows: %LOCALAPPDATA%\Gravewall\Saved | To continue where you stopped and keep your settings. |
| Technical files (graphics shader cache and, on Windows, a log file) | Android: Android/data/com.valtoragames.gravewall. Windows: %LOCALAPPDATA%\Gravewall\Saved\Logs | To load faster and to help find errors. The Windows log may contain folder paths that include the Windows user name. It stays on the computer. |
The game never asks for your name, age, e-mail address, photo or any other personal data, and none of these files leaves your device.
3. Permissions on Android
The Android version asks for no permission that needs your approval. The system lists a few automatic permissions that come with the game engine: internet and network state (Google Play uses them to deliver the game data; the game itself sends nothing), vibration, keeping the screen awake during a match, and audio settings. The game does not use the camera, microphone, contacts, photos, files outside its own folder or location.
4. Stores and other companies
The game uses no analytics, no advertising, no trackers and no third-party services, and it does not open web pages.
The store where you get the game (for example Google Play or Steam) handles your account, download and purchase data under its own privacy policy. We do not receive that data, apart from the anonymous sales and installation statistics that stores give every developer.
In the Steam version, the game reads the language selected in Steam, so it opens in the right language, and unlocks Steam achievements. Achievements are stored by Steam on your Steam account, under Steam's privacy policy; nothing is sent to us.
5. Children
GRAVEWALL contains violence against zombies and is not made for young children. It collects no personal information from anyone, including children.
6. How to delete everything
Android: uninstall the game, or clear its storage in the system settings (Apps > GRAVEWALL > Storage > Clear data). This deletes your progress and settings.
Windows: uninstall the game and delete the folder %LOCALAPPDATA%\Gravewall.
7. If you write to us
If you send an e-mail to the contact in section 1, we receive your e-mail address and whatever you write. We use it only to reply and sort out your request; we send no advertising and share it with no one, except the e-mail service we use to receive the message. We delete the conversation once the matter is closed, within 12 months. The legal basis is our legitimate interest in answering people who contact us (GDPR Art. 6(1)(f); LGPD Art. 7, IX).
8. Your rights
The game sends us no data, so for the use of the game there is nothing for us to access, correct or delete. If you wrote to us, you can ask at any time for a copy, correction or deletion of your message through the contact in section 1. You can also complain to the data-protection authority of your country, for example the CNIL (France), the ANPD (Brazil) or your national authority in the European Union.
9. Changes to this policy
If a future version of the game ever adds an online feature, ads or purchases, this policy will be updated before that version is released, and the store page will say so. The date at the top shows the version in force.
