HDRI StudioPrivacy Policy
Effective 28 June 2026
HDRI Studio turns a set of bracketed iPhone photos into a 360° HDR environment map. This policy explains what the app does with your data. In short: your photos are used only to build your panorama, there are no accounts, and nothing is sold or shared with advertisers.
What the app captures
To build an HDRI the app records two things, only while you are actively capturing: the bracketed RAW (DNG) photos of your surroundings, and your device’s orientation from the motion sensors at each shot so the photos can be placed correctly on the sphere. The camera and motion sensors are used solely for this purpose.
Where your captures go
Stitching happens on the server shown in Settings. By default, the app uses the hosted HDRI Studio processing server so captures can be processed without a Mac on your local Wi-Fi. You can replace it with your own server URL at any time. Your captures are uploaded only to be merged and stitched into an EXR, and the finished panorama is returned to your device.
What we do not collect
No account or sign-in. No analytics, tracking, advertising identifiers, or third-party SDKs. We do not collect your location, contacts, or any personal information beyond the photos you choose to capture. We never sell or share your data.
Purchases
Payments are handled by Apple through StoreKit. HDRI Studio can see whether an in-app purchase or subscription is active so it can unlock processing quota, but we do not receive or store your payment card details. Free capture counts, purchased credits, and subscription usage are stored locally on your device.
Storage and retention
Captures and finished EXRs are stored on your device until you delete them. The hosted HDRI Studio server keeps only a rolling processing cache, currently the newest 6 jobs, then removes older uploaded bundles and generated results as retention rotates. To request earlier deletion of a hosted-server job, contact privacy@hdristudio.app with the server job ID or EXR filename. If you use a custom server URL, that server’s operator controls its own retention. You can delete any local capture or panorama from inside the app at any time.
Local network access
The app may request Local Network permission when you point it at a server on your Wi-Fi. It is used only to upload captures and download your finished panorama.
Children
HDRI Studio is not directed to children under 13 and does not knowingly collect data from them.
Changes to this policy
We may update this policy as the app evolves; the effective date above changes when we do.
