Information Used by Photo Assist
Photo Assist stores equipment profiles, the active profile, preferences, consultations and favourites on your devices to personalise recommendations and retrieve previous consultations.
Equipment profiles and consultations are exchanged between your paired iPhone and Apple Watch using Apple’s WatchConnectivity technology. Favourites are stored locally on each device.
Photo Assist does not require a user account or send this information to Focal35 servers.
Information Used by PhotoKalk
PhotoKalk uses the values entered in its tools to perform the requested photography calculations, including aperture, focal length, sensor size, subject distance, exposure time and ISO.
Retention and Deletion
In Photo Assist, you can edit or delete equipment profiles under “My equipment”. To remove local data, delete the application and its data from the devices where it is installed.
Backups and restoration depend on your settings and Apple services. Focal35 does not manage these backups.
