BlockBuild — Privacy Policy
This Privacy Policy explains how BlockBuild ("the App"), published via jpmtech.dev, handles your information and device permissions on iOS and iPadOS.
Summary: Zero Personal Data Collection
BlockBuild does not collect, store, track, or sell any personal data. There are no user accounts, no analytics SDKs, no advertising trackers, and no external cloud servers receiving your gameplay data. All saved worlds remain locally on your device.
1. Information We Collect
We do not automatically collect any personal information, device identifiers, location data, or usage telemetry when you play BlockBuild.
- Saved Worlds & Preferences: Your voxel worlds, inventory states, and HUD layout settings are stored locally on your device using standard iOS local storage.
- Voluntary Support Emails & Mailing List: If you choose to contact us for support or subscribe to app updates via jpmtech.dev@gmail.com, we receive only the email address and message details you voluntarily send us in order to reply or send requested release notes.
2. Device Permissions & How They Are Used
BlockBuild requests specific iOS system permissions only when you use features that require them:
| Permission | Purpose in BlockBuild | Data Handling |
|---|---|---|
Local Network (Bonjour)_blockbuild._tcp / _udp |
Used so nearby players on the same Wi-Fi network can discover and join your voxel world for local multiplayer. | Direct peer-to-peer connection on your local network only. No data is sent to external servers. |
| Bluetooth | Used for local peer-to-peer multiplayer discovery and connection with nearby devices. | Used strictly in real time between nearby devices; never logged or transmitted off-device. |
| Photo Library (Add Only) | Used when you take in-game screenshots of your voxel world and save them to your Photos library. | Write-only access (NSPhotoLibraryAddUsageDescription). The App cannot read or view your existing photo library. |
3. Children's Privacy
BlockBuild does not knowingly collect personal information from anyone, including children under the age of 13. Because all gameplay and world storage occur locally on the device without external data transmission, the App is safe for players of all ages.
4. Third-Party Services
BlockBuild does not integrate any third-party advertising networks, behavioral analytics SDKs, or external data brokers.
5. Changes to This Privacy Policy
If future updates to BlockBuild introduce new features that affect device permissions or privacy, we will update this page and revise the "Last Updated" date at the top before releasing the update.
