Privacy Policy
Summary
QuestGun does not collect, store, transmit or share any personal data.
The application has no network capability. It requests no permission that grants access to your data, your device or the outside world, and contains no analytics, advertising, crash-reporting or telemetry components. Nothing you do in QuestGun leaves your headset.
The remainder of this policy explains that in the detail the Meta Horizon Store requires.
1. Who we are
QuestGun is published by SludgeSoft, an independent sole-trader software developer. Contact details are in section 11.
For the purposes of UK GDPR and the EU General Data Protection Regulation, SludgeSoft would be the data controller for any personal data processed through QuestGun. As set out below, we do not process any.
2. What data we collect
None.
We collect no personal data, no device identifiers, no usage analytics, no crash reports, no advertising identifiers, no location data, no voice or audio recordings, no camera imagery, no hand or body tracking data, no eye tracking data, and no account information.
We do not ask you to create an account, sign in, or provide any information about yourself.
3. Why there is nothing to collect
This is verifiable rather than a promise, which is why we state it plainly:
- No network permission. QuestGun declares no
INTERNETpermission, so Android prevents the application from opening any network connection at all. It is not that we choose not to send data; the application is technically incapable of sending it. - The only permissions present. The installed package declares exactly two:
org.khronos.openxr.permission.OPENXRandorg.khronos.openxr.permission.OPENXR_SYSTEM. Both are required by the standard Khronos OpenXR loader to talk to the headset's VR runtime, both are contributed by that library rather than written by us, and neither grants access to storage, the camera, the microphone, the network, your location or your account. There are no others. - No third-party SDKs. QuestGun's only external dependency is the Khronos OpenXR loader, which is the standard library used to talk to the headset's VR runtime. There is no analytics library, no advertising library, no crash reporting service and no social integration.
- No storage permission. QuestGun reads and writes only inside its own application-specific directory, which Android grants to every app without a permission request. It cannot read your photos, documents, downloads, or any other application's data.
4. Data stored on your device
QuestGun reads files that you place into its own application directory:
/sdcard/Android/data/com.questgun.arcade/files/This includes emulator core files, game data, and an optional autoload.txt configuration file. These files are supplied entirely by you, remain on your device, and are never read for any purpose other than running the software you have asked QuestGun to run. They are never transmitted anywhere.
Uninstalling QuestGun removes this directory and everything in it, in the normal Android manner.
5. Headset sensor data
To function as a virtual reality application, QuestGun receives head and controller position data from the headset's OpenXR runtime while it is running. This is used solely and immediately to draw the correct image for your eyes and to calculate where your controller is aiming.
This data is held in memory for the duration of a single frame, is never recorded, never written to storage, and never transmitted. QuestGun does not use hand tracking, eye tracking, face tracking, body tracking, passthrough camera imagery, or the microphone.
6. Third-party emulator cores
QuestGun is a frontend, not an emulator. It loads emulator "cores" that you download and install yourself, from sources of your choosing such as the libretro project.
These cores are independent third-party software, not written, distributed or controlled by SludgeSoft. This privacy policy does not cover them. Their behaviour is governed by their own authors and licences. Because QuestGun holds no network permission, a core running inside QuestGun is also unable to reach the network — but you should still satisfy yourself as to the provenance of any software you install.
7. Data sharing and selling
We do not share, sell, rent, disclose or transfer personal data to anyone, because we do not have any. There are no third-party recipients, no data processors, and no international data transfers.
8. Children's privacy
The Meta Horizon Store requires users to meet Meta's own minimum age requirements, and virtual reality headsets carry their own manufacturer age guidance which you should follow.
QuestGun collects no data from anyone, of any age. We therefore do not knowingly collect personal information from children, and could not do so if we wished to.
9. Your rights
Under UK GDPR, EU GDPR, the California Consumer Privacy Act and comparable legislation, you have rights to access, correct, delete, port and restrict the processing of your personal data, and to object to it.
We hold no personal data about you, so there is nothing for us to retrieve, amend or erase. You are welcome to contact us to confirm this, and we will respond to any such request.
10. Changes to this policy
If QuestGun's data practices ever change — for example if an optional online feature were added in a future version — this policy will be updated before that version is released, and the "last updated" date above will change. Material changes will be noted in the application's store listing release notes.
