On-device processing
Crop, DPI header injection, and exact KB matching run in your browser with the Canvas API. SpecSnap does not receive, store, or transmit the original image.
No sign-in, no watermark
Downloads are unbranded. Closing the tab drops the working image from memory. We cannot recover a photo we never received.
Anonymous usage counters
Optional events record only country code, tool id, and language so we know which specs are used. No names, photos, filenames, IPs, or user-agents. Localhost Admin can export or clear counters.
What this browser may keep
A random session id, optional Admin spec overrides, and your last country or language. SpecSnap does not set advertising cookies and does not load third-party trackers for photos.
Your controls
Upload only what you choose. Clear this site’s data in the browser to wipe local counters and overrides. On a self-hosted copy, analytics files stay on that machine.
