SnapDimension helps you put manually entered dimensions and notes on photos. We do not operate an account service or an app backend.

Photos and project data

Photos you take or select, annotations, dimension values and project names are stored in the app’s private storage on your iPhone. SnapDimension does not automatically upload this content. Local project storage is excluded from automatic device backup. There is no cloud sync or automatic backup service. Deleting a project or uninstalling the app removes the corresponding editable local data. Export important work first. Exported images and PDFs contain flattened annotations and do not restore editable projects.

The system photo picker gives the app only the photos you choose. You do not have to grant unrestricted access to your photo library. Camera permission is requested only when you choose to take a photo. You can turn camera access off in iPhone Settings and continue importing selected photos.

Photos are normalized and re-rendered for export; original location metadata is not included in exported files. Your visible photo content, project title, annotations and entered dimensions are included in the exported image or PDF. Check them before sharing.

Sharing

Sharing happens only when you choose Export and share and select a destination using the iOS share sheet. The chosen person, app or service receives the file and may store, process or further share it according to their own practices. If you choose Save Image, iOS may request add-only Photos permission. A copy saved to Photos may sync through iCloud Photos under your device settings; this happens outside SnapDimension and only after your save action. Copies you save or send remain outside SnapDimension’s control. Temporary export copies may remain in system temporary storage until the share sheet closes or iOS removes them; local copies are not transmitted by us.

Purchases

Apple processes the optional Lifetime Pro purchase through your Apple Account. SnapDimension checks Apple’s verified transaction information on your device to enable Pro and restore purchases. We do not receive your payment card information or operate a purchase database. Apple’s privacy policy applies to Apple’s processing.

Analytics, advertising and tracking

SnapDimension contains no advertising or third-party analytics SDK, and does not track you across apps or websites. We do not collect your photos, notes, identifiers, location or device activity on a server. Apple may provide aggregated App Store sales or app analytics reports to the publisher under Apple’s terms and your device settings; the app does not send separate analytics events to us.

Your choices

Use the free app without an account. Deny camera access and import only selected photos instead. Delete local projects using the project list. Decide what to include in exported files and where to send them. To manage purchase or refund requests, use Apple’s purchase services. For app questions, open an issue on our GitHub support page. Issues are public: do not post private photos, addresses, payment details or other sensitive information. We use the information you intentionally post to respond and resolve your question. GitHub hosts this support website and issue tracker, and processes website visits and issue data under its own privacy statement (https://docs.github.com/en/site-policy/privacy-policies/github-privacy-statement). Issue content remains visible until removed by you, the repository maintainer or GitHub. You can request removal of a support issue through the same tracker. This support channel is separate from the app; the app sends no automatic reports or project data to it.

Changes

We will update this policy if the app’s privacy practices change. The published version will state its effective date. Future changes that introduce data collection require a fresh review of permissions and App Store privacy disclosures.
