Privacy Policy — PDF Sign

Last updated: April 29, 2026

Inside the Chrome extension

What the extension does

PDF Sign is a Chrome extension that lets you sign PDF documents directly in your browser. All PDF processing happens locally on your device — your files are never uploaded to any server.

Data we collect

Email address

When you sign in with Google, we receive your email address. We use it solely to:

• Authenticate your account
• Track how many documents you have signed (to enforce the free tier limit)

Your email is stored in our authentication provider (Supabase). We do not sell, share, or transfer your email to any third party.

Usage count

We store a numeric counter of how many documents you have signed, linked to your account. This is used only to enforce the free tier limit (1 free document).

IP address (short-lived, abuse prevention)

When you sign in, the sign-in endpoint briefly records the IP address your request originated from in a rate-limit log. This log is used exclusively to block automated abuse on the anonymous sign-in endpoint. Entries are automatically deleted after 10 minutes and are never linked to your account or used for any other purpose.

Data we do NOT collect

• PDF file contents — your documents never leave your device
• Browsing history or web activity
• Location data
• Keystrokes, mouse movements, or other user actions
• Website content

Third-party services (extension)

• Google Sign-In — used for authentication only. See Google's Privacy Policy.
• Supabase — our backend provider that stores your email, usage count, and the short-lived rate-limit log described above. See Supabase's Privacy Policy.
• ExtensionPay — used to process Pro subscription payments. ExtensionPay uses Stripe as its payment processor. Your payment information (card number, billing address) is handled entirely by Stripe and is never stored by us. See Stripe's Privacy Policy.

Data retention

Your account data (email and usage count) stays as long as your account exists. Rate-limit log entries are deleted automatically after 10 minutes. To request deletion of your account, contact us at the email below.

What this website does

This is a static marketing page describing the PDF Sign Chrome extension. It contains no forms, no accounts, and no document handling — all of that lives inside the Chrome extension, not here.

Data we collect on this website

Aggregated analytics

We use Cloudflare Web Analytics to count page views and identify which external sites link to us. It is cookie-free and does not track individual users across sessions. Cloudflare processes your IP address and user agent to produce aggregated counts (country, browser, referrer) but does not store individual-level records on our side.

Data we do NOT collect on this website

• We set no cookies
• We host no forms
• We use no tracking pixels, fingerprinting, or retargeting
• The site has no sign-in and no account system — those live in the Chrome extension

Third-party services (website)

• Cloudflare (Pages + Web Analytics) — hosts the website and provides anonymous analytics. Cloudflare sees your IP address (required to deliver the page) and processes it under its own terms. See Cloudflare's Privacy Policy.
