Privacy Policy

Last updated July 2026

SherlockX helps you check the provenance of a photo or object using reverse image search and AI analysis. This is not facial recognition — we do not build, store, or match biometric face templates. We match whole images and the public web pages they appear on. This policy applies to both the SherlockX website and the SherlockX mobile app.

Face data

SherlockX does not collect, create, or store face data, and is not a facial-recognition app. We do not detect, scan, map, or measure faces, and we do not create, derive, or store face templates, faceprints, face geometry, or any other biometric identifier. Matching is done on the whole image — a reverse-image search for the same picture — not on facial features. No face data is collected, so none is shared with third parties and none is retained.

Photos you upload

Photos are sent over an encrypted connection to our analysis service only for the duration of a single check. They are processed in memory and are not retained after the report is generated. We do not sell your uploaded photos, use them to train models, or use them for advertising or ad targeting.

Your history stays on your device

Past checks and their thumbnails are stored locally on your device — in your browser on the web, and on-device in the mobile app — and never leave it. Clearing your browser data, or using the "Clear all" button in the app or on the site, removes them permanently. History is not synced across devices.

Account and billing

If you subscribe, we store your account identifier, email, and subscription status to provide premium access. Payments are processed by Stripe; we never receive or store your full card details. Sign-in is handled by Firebase Authentication.

Anonymous usage limits

To offer a free check without requiring an account, we generate a device identifier in your browser to count free usage. It is not linked to your identity unless you choose to sign in.

Analytics and cookies

We use privacy-respecting analytics to understand aggregate, anonymous traffic such as page views and which features are used. We do not use third-party advertising trackers, and we never send your uploaded photos, search results, or other content to analytics. You can block these cookies in your browser without affecting how the service works.
