The short version
Your PDFs never leave your device. All PDF reading, editing, and signing happens in your browser using pdf-lib. We never upload, store, or see the documents you sign.
What we collect
Without an account
- Nothing from your PDFs. They stay on your device.
- Standard web analytics — anonymous page views and device type.
- Advertising cookies — served by Google AdSense once enabled. See Google's privacy policy.
With an account
- Email address — for authentication, stored by Supabase.
- Saved signature images — PNG files you explicitly save, stored in a private bucket keyed to your user ID. Only you can access them.
What we don't do
- No server-side PDF processing. Ever.
- No selling of personal data.
- No tracking you across other sites.
- No AI training on your documents.
Your rights
Account holders can delete their account and all associated data at any time from the account page. This permanently removes your email, saved signatures, and any stored preferences.
