the privacy moat
Built for people who don't trust period apps.
Anonymous Mode
Use HUSH without an email or sign-up. Your data stays on this device, in encrypted local storage. Nothing reaches our servers.
End-to-end encrypted
When you do sync, your logs are encrypted on the phone with tweetnacl secretbox before they leave. The server stores ciphertext only — we cannot decrypt your data.
Built without trackers
No ads. No third-party analytics. No Sentry. No PostHog. No resold data. The business model is the subscription — never your data.
