Reverse image search by photo

iPhone
See where your photo turns up online. One selfie, and Sherlock scans over a billion public images for matches — with a confidence score on every single result.
Sherlock is a reverse image search for faces. Add a photo of yourself and see where that photo appears across publicly available sources on the web — the same idea as a reverse-image search, applied to a face.
WHAT YOU CAN DO
• See where your photo appears online — social posts, blogs, news, and other public pages.
• Spot stolen or reused pictures of you.
• Find accounts that use your photos to impersonate you, so you can report them.
• Check your own public image footprint.
HOW IT WORKS
1. Add a clear photo of yourself.
2. We run a visual-similarity (reverse image) search across public web sources through our search provider.
3. You get a list of matching images and the source pages where they appear, ranked by visual similarity.
WHAT SHERLOCK IS NOT
Sherlock does not build, store, or maintain any profile, dossier, or database of any person. It does not identify people, reveal names, or compile personal information. Every search returns only image matches and their public source links — nothing more — and results are never saved.
PRIVATE BY DESIGN
• We don't store the photos you search.
• Your photo is sent only to our third-party search provider (FaceCheck.ID), with your explicit in-app consent, solely to run the search — and is deleted by the provider within 24 hours.
• No ads in the app. Advertising attribution is used only as described in our Privacy Policy and follows your iOS tracking choice.
RESPONSIBLE USE
You must be 18+. Search only your own face, or a photo you have explicit permission to search. Do not use Sherlock to identify, profile, monitor, harass, or stalk anyone, to upload photos of minors, or for employment, housing, credit, insurance, or other FCRA-covered decisions. Results are based on visual similarity, can be incomplete or inaccurate, and never confirm anyone's identity.
