TileMatch – Privacy Policy

Last updated: 2026-05-06

TileMatch is a tile-installation planning app for iPhone and iPad. This policy explains, in plain language, what data TileMatch handles and what we do (and don’t do) with it.

The short version

What data TileMatch handles

Data Where it lives What we do with it
Tile photos (originals, processed, thumbnails) Your device, and your private iCloud Documents container if iCloud is enabled Display them, run on-device image analysis (rectangle detection, perspective correction, white balance, vein matching, duplicate detection)
Project metadata (name, format, surfaces, grids, cut records) Same as above Persist your work so it’s there when you reopen the app
Camera frames (Smart Capture) Used only to produce a single tile photo when you tap to capture, then discarded Become a tile photo as above
Photo-library images you select (Upload Photos) Copied into the project’s storage; the originals stay in your library Become tile photos as above

What TileMatch does not do

How sync works

If you are signed in to iCloud and iCloud Drive is enabled, TileMatch stores its projects in your iCloud Documents container. Apple manages the storage; only your devices, signed in to your iCloud account, can read it. Apple’s iCloud privacy applies — we have no access to it.

If you sign out of iCloud or disable iCloud Drive on your device, TileMatch falls back to local-only storage. Your projects are then on the device only and won’t sync.

Camera and photo library

Image processing

All image analysis runs on your device using Apple’s Vision and Core Image frameworks (rectangle and document segmentation detection, perspective correction, gradient-based corner refinement, LAB-space white balance, feature-print duplicate detection). No image data leaves the device for processing.

Children

TileMatch is not directed at children under 13 and does not knowingly collect data from anyone, including children. The app is rated 4+ on the App Store.

Data retention and deletion

Your data lives in your iCloud Documents container (if iCloud is enabled) and on your devices for as long as you keep the app installed. You can delete projects individually from the app’s project list.

To remove all TileMatch data:

  1. Uninstall the app from each device.
  2. In iOS Settings, go to Apple ID → iCloud → Manage Account Storage → TileMatch → Delete Data.

This is a complete, irreversible deletion.

Changes to this policy

If we ever update this policy, the new version will be posted at the same URL with an updated date at the top. We will not change TileMatch to collect more data than this policy describes without prior notice.
