BSD Studio Privacy Policy
1. Local-first processing
- Your source data stays on your device. Photos, drone imagery, video, camera parameters and LiDAR point clouds you import are processed entirely in your computer's memory, GPU and disk during alignment, training and rendering. We do not collect, upload, back up or share them.
- Your 3D results stay on your device. Gaussian splat files (PLY), meshes (OBJ / PLY / GLB) and camera paths are written to the project folder you choose. We do not keep or sync any of them.
2. Information we collect
We collect only what is needed to run your account, verify your license and process your orders.
(1) Account and sign-in
- Email address and one-time codes. We use your email address to send sign-in codes, create your unique account ID (UID) and manage your plan. Users in mainland China may sign in with a mobile phone number instead.
- Session data. Signed session tokens, sign-in time and sign-in status, used to keep you signed in securely across pages and the desktop app.
(2) License and devices
- Hashed device identifier. When a license is activated, the app derives a device ID from hardware characteristics (such as motherboard, CPU and network adapter) using a one-way SHA-256 hash. It cannot be reversed into your hardware serial numbers or your identity.
- License status. Your plan (Basic, Pro monthly / yearly), its start and end dates, and the device currently signed in, so you can manage it on the Devices page.
(3) Orders and payments
- Order records. When you buy Pro we record the order number, the payment provider's transaction ID, the plan, the amount, the currency and the payment time, to activate your license and provide receipts and support.
- Card details. Payments are handled by our payment provider. We never receive or store your card number, security code (CVV) or payment account password.
(4) Diagnostics you choose to send
- If you choose to send us a crash or error report, it may contain error codes, GPU model, driver version, CUDA runtime version and operating system version. It does not contain your images, point clouds or project content.
3. How we use information
