All encryption happens in your browser
The Secret Sharer encrypts with AES-GCM before anything reaches a server. Decryption keys live only in URL fragments.
Anonymized breach lookup
Breach checks use k-anonymity. Only the first 5 chars of a SHA-1 hash leave your device.
Open to audit — no black box
Every page's source is viewable. No analytics, no fingerprinting, no third-party trackers beyond display ads.
Every tool here is free
No accounts, no subscriptions, no locked features. Every tool runs entirely in your browser and is supported by ads — that's the whole model.
