Your data stays on your machine.

No servers. No accounts. No cloud sync. No "we value your privacy" 47-page PDF.
Just a Chrome extension and your local IndexedDB.

Zero network calls

Your annotations never leave the browser. We don't need 300 third-party SDKs to render ASCII box-drawing characters. Shocking, we know.

Optional telemetry

Anonymous usage stats (which tools you click, not what you type). Off by default. One toggle in settings. We'll survive without your data.

Manifest V3

Minimal permissions. No background persistence. The extension can't read your tabs unless you click it. We're not that nosy.

No subscription. Ever.
