Privacy Policy

Last updated June 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.

Photos you upload

Photos are resized in your browser and 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 use your uploads to train models.

Your history stays on your device

Past checks and their thumbnails are stored locally in your browser (localStorage) and never leave your device. Clearing your browser data or using the "Clear all" button 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 Google Analytics to understand aggregate, anonymous traffic such as page views and which features are used. This relies on cookies and sends usage events to Google; 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.
