We'll only know about you if you decide to tell us. In the meantime, here's what you can check for yourself.
It runs in your browser
Encryption, hashes and analysis happen on your device. Your files and text never reach our servers.
No account, no paywall
No sign-up and no mandatory paid tier to use the tools. We don't sell your data because we don't collect it.
No third-party trackers
No cross-site behavioural profiles. Just aggregate usage metrics so we know what to improve.
Verifiable
Standard algorithms (AES-256, SHA-2, TOTP) and behaviour you can audit from the DevTools.
Encrypt, share and disappear

We'll only know about you if you want us to. No spam, unsubscribe whenever you like. See the Privacy Policy.
