Privacy

Nothing leaves your device.

Parallelogram does all of its work — depth analysis, foreground masking, background inpainting, and video encoding — on your iPhone or iPad. Your photos are never uploaded, shared, or sent to a server. The app does not contain analytics, telemetry, ads, or third-party SDKs.

What the app needs access to

• Photos. When you pick a photo, iOS grants the app temporary access to just that asset. The app additionally requests read-only Photos library access on first pick so it can fetch the original file (including Apple’s measured depth metadata for Portrait Mode photos). Photos are read into memory, processed, and discarded when you pick a new photo or close the app.
• Photo library add access. If you choose “Save to Photos” from the share sheet after export, the system saves the exported video to your library. The app does not write to Photos at any other time.

What happens when you export

Tapping Export & Share writes an .mp4 file to the app’s temporary directory. From the share sheet you choose where it goes — Save to Photos, Messages, AirDrop, Mail, social apps, etc. The app itself never sends the file anywhere.

Data collection

None. Parallelogram does not collect, store, or transmit any personal data, usage data, or device identifiers.

Children

The app is suitable for all ages. It does not knowingly collect any information from anyone, including children under 13.

Changes

If this policy ever changes, the updated version will appear on this page. Material changes will also be reflected in a new app version.

About

Parallelogram turns any photo into a looping spatial video. It uses the depth in your photo (measured directly when shooting in Portrait Mode, or estimated on-device for everything else) to drive a small camera motion that makes the subject pop out from the background.
