Frequently asked questions

Where do my keywords go?
Straight into your Apple Photos library, as the same keyword field Photos itself uses — any app that reads Photos keywords sees them, and they stay in your library if you delete TAG Lens.
Does TAG Lens upload my photos?
No — your photos never leave your Mac for the internet. Every network feature is off by default behind its own consent switch, and each sends only what’s named: related-keyword enrichment sends only the tag term you typed to a public reference API (Wikidata, and/or Grokipedia — a keyless wiki lookup with its own consent switch); AI keyword suggestions send only that term to the AI provider you choose (xAI, OpenAI, Anthropic, Mistral, Groq, DeepSeek, or your own local/custom endpoint — using your own key); place-name lookup sends a photo’s GPS coordinates to Apple’s geocoder; and place-from-photo-text sends a place name read off a sign in a No-Location photo (never the photo) to Apple’s location search. The only feature that reads a photo’s pixels works solely with a model running on your own Mac (a loopback address) — those pixels never reach an internet endpoint. Details in the privacy policy.
Can I undo a change?
Every metadata write records its reverse on ⌘Z — up to 50 actions in a session, and a multi-photo batch undoes as one action. Deleting is the exception: deleted photos go to Photos’ own Recently Deleted album, recoverable for about 30 days.
Can TAG Lens delete my photos without asking?
No. The app never deletes on its own. Both delete paths — culling rejected photos and the inspector Delete button — go through Apple’s standard system confirmation dialog, after which items land in Photos’ Recently Deleted, recoverable for about 30 days.
Does TAG Lens edit my photos?
Never. It is not a photo editor: it writes metadata — keywords, titles, captions, favorites, album membership, capture dates, locations — and never modifies image pixels.
Why did my star ratings disappear after a Photos library rebuild?
Photos has no write API for star ratings, so TAG Lens keeps stars and reject marks in an app-local file keyed to each photo’s Photos identifier — and a rebuild can change those identifiers. Export a JSON backup from Settings ▸ Ratings Backup before a migration, then import to reattach them.
Does it work with iCloud Photos?
Yes. Metadata TAG Lens writes syncs to your other devices the same way any edit made in Photos itself does — on iPhone and iPad, search finds your keywords (iOS has no screen that displays them). If an original lives only in iCloud, TAG Lens can fetch it automatically for viewing (Settings ▸ General ▸ Download originals automatically); metadata edits work either way.
TAG Lens can’t see my photos, or says Photos control is not authorized
TAG Lens needs two macOS permissions: Photos library access (System Settings ▸ Privacy & Security ▸ Photos) and automation control of Photos (System Settings ▸ Privacy & Security ▸ Automation) to write keywords, titles, and captions. Step-by-step fixes on the support page.
What does it need to run?
macOS 14 or later, and your Apple Photos library. No account or sign-in for tagging, and no subscription — culling and rating are free forever, keywording your first 500 photos is free, and the optional one-time unlock for unlimited keywording is a standard App Store purchase with your Apple Account.
