Overview
Tagback helps restore missing location metadata on imported digital camera photos. The core design principle is local-first processing: the main scan, comparison, review, and decision flow runs on your device.
Data Tagback can access
If you grant permission, Tagback can access the following information for its repair workflow:
- Photos in your Photos library
- Photo capture timestamps
- Whether a photo already contains GPS metadata
- Existing location metadata in photos
- Thumbnails or preview images needed for repair review
- Location metadata written back to Photos when you explicitly approve a repair
- App Store purchase entitlement information needed to unlock or restore Tagback Pro
How Tagback uses this data
Tagback uses this information to find photos missing GPS metadata, compare them against nearby iPhone reference photos from the same time window, classify results for automatic approval or review, and write approved location repairs back into Photos only after you confirm the save step.
Tagback also checks and restores App Store entitlement state for Tagback Pro monthly subscriptions and lifetime purchases.
Uploads and server processing
Tagback does not upload your photos or photo library to developer-owned servers. The main metadata repair workflow does not require account creation, sign-in, or a Kinno Labs cloud sync account.
Payment information
Tagback Pro monthly subscriptions and lifetime purchases are processed through Apple's In-App Purchase system. Monthly subscriptions can be managed or canceled from the App Store subscription settings for your Apple Account. Payment method details are handled by Apple, and Kinno Labs does not receive your payment card information.
Analytics, tracking, and advertising
Tagback does not currently include its own advertising SDK and does not use third-party ad tracking to follow users across apps or websites. Tagback's core workflow does not require a developer-run account system or personal profile collection.
Apple services and third-party processing
Tagback uses Apple-provided system frameworks. Photos access uses Apple's PhotoKit, and map previews may use Apple's MapKit. These Apple-provided services may involve network communication as part of Apple's platform behavior, and Apple's own policies may apply to that processing.
Your control over photo changes
Tagback is designed so that no change is applied to your Photos library until you explicitly confirm the save step. Buying Tagback Pro alone does not automatically modify any photo.
Data retention
Tagback's core processing happens on device. Kinno Labs does not keep a server-side copy of your photo library. Apple purchase records, Photos system records, or operating system logs may still be handled under Apple's policies and your device environment.
Children's privacy
Tagback is a general-purpose utility app. It does not operate a dedicated child-directed account or direct personal data collection flow.
