Privacy Policy

Last updated: April 9, 2026

1. Introduction

PDFStamp ("we," "us," or "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard information when you use our website and services.

PDFStamp is a browser-based PDF stamping tool. Your files are processed entirely in your browser and are never uploaded to our servers.

2. Information We Don't Collect

PDF Files: We do not collect, store, or have access to any PDF files you process with PDFStamp. All processing happens locally in your web browser using client-side JavaScript. Your documents never leave your device.

Personal Documents: We have no access to the content of your PDFs, stamps, or any data you process through our service.

3. Information We Collect

We collect minimal information necessary to operate our service:

Payment Information

Payments are processed by LemonSqueezy, our third-party payment provider. We do not store your credit card, bank account, or payment details. All payment processing is handled directly by LemonSqueezy according to their Privacy Policy.

Account Information

When you purchase a subscription, LemonSqueezy provides us with:

  • Email address (for account recovery and receipts)
  • Subscription status (active/inactive)
  • Subscription tier (Pro, Agency)
  • License identifier (for subscription management)

Usage Data

We may collect anonymous usage statistics such as feature usage patterns to improve our service. This data is aggregated and cannot be used to identify you or your documents.

4. Cookies

We use minimal cookies for essential functionality:

  • Subscription Status: To remember your subscription tier and unlock Pro features
  • Local Storage: To save your custom stamp templates and preferences

We do not use tracking cookies, advertising cookies, or third-party analytics cookies.

5. Third-Party Services

We use the following third-party services:

  • LemonSqueezy: Payment processing and subscription management. Their Privacy Policy applies.
  • Cloudflare: Website hosting and CDN. Their Privacy Policy applies.

6. Data Retention

Since we don't collect PDF files, there is no data to retain on our servers. Your subscription and account information is retained for as long as your subscription is active, and for 30 days after cancellation for account recovery purposes.

7. Data Security

Your PDF files are processed entirely in your browser using industry-standard encryption. Since we never receive or store your documents, there is no risk of data breach on our servers for your PDF content.

Account credentials and payment data are handled by LemonSqueezy, who maintains PCI-DSS compliance.
