Does Kyanix read my email?

No. Kyanix reads only message headers (From, Subject, Date, List-Unsubscribe). Message bodies and attachments are never touched.

Yes, free during beta. A free tier will always exist when paid plans launch — see /pricing.

Any time. Disconnect from Settings, or revoke at myaccount.google.com/permissions. Your data is purged immediately.

No. Sender priority is a transparent rule-based score on frequency and unread ratio. No LLMs, no embeddings, no black box.

How do you store my Google tokens?

Encrypted at rest with AES-GCM (256-bit). Decrypted only in memory when calling the Gmail API on your behalf.

Can I keep all data on my device?

Yes. After login you choose Cloud sync or Local-only. Local-only purges server-side sender stats and keeps them in your browser.

Everything you need to take your inbox back.

Built for people who measure their week in unread badges.

1-click RFC 8058 unsubscribe

Where senders implement the standard, Kyanix unsubscribes via the one-click endpoint. Otherwise mailto: or web link.

Universal inbox

Connect multiple Gmail accounts; Kyanix merges sender stats into a single view across all of them.

Account security

Auto-scan every linked email across HIBP, XposedOrNot, and LeakCheck. Mark breaches fixed; risk score updates.

Domain intelligence

Lookup MX/SPF/DKIM/DMARC, certificate history, popularity, and a safety verdict before clicking any link.

How it works

From cluttered inbox to clean in four steps.

Connect Gmail

Google OAuth — read-only by default.

Scan headers

Only From/Subject/Date headers, never the body.

Review noisiest

Top 100 senders ranked by a transparent score.

Unsubscribe

1-click RFC 8058 where supported, mailto/web fallback otherwise.

AES-GCM token encryption

Email breach scanning

Every connected inbox is auto-checked against HIBP, XposedOrNot and LeakCheck.

Pwned password check

k-anonymity SHA-1 lookup against HIBP's 800M+ leaked password corpus. Your password never leaves the browser.

Breach timeline & types

See exactly which sites leaked, what was exposed (emails, passwords, IPs, hashes), and when.

Mark as fixed

Rotate the password, mark it secured. Risk score drops; secured items get their own tab.

Domain intelligence

MX / SPF / DKIM / DMARC / DNSSEC / RDAP across Google, Cloudflare and Quad9 — no single point of trust.

URL safety verdict

Mozilla Observatory grade, Tranco popularity, crt.sh certificate history, URIBL/SURBL blocklists, phishing signals.
