Privacy
Last updated: 2026
The short version
Sigmint generates your email signature entirely in your browser. The name, title, email, phone number, and any other detail you type never leave your device and are never transmitted to or stored on our servers.
What we store locally
To make your life easier, we save your in-progress signature in your browser's
localStorage. That data stays on your machine and you can clear it anytime by
clearing your browser storage.
Payments
If you buy the Pro unlock, the payment is processed securely by our payment provider (Creem, a merchant of record). We never see or store your card details. After a successful payment we store a small license token in your browser to unlock Pro features — nothing that identifies you personally.
Analytics
We may use privacy-friendly, cookieless analytics to count page views in aggregate. We do not build advertising profiles and we do not sell data. Ever.
