Privacy

Last updated: November 13, 2026

This policy explains how Shrink a PDF at shrinkapdf.com handles information. The service is operated by ZHU PENGFEI, an individual in China. Contact: support@shrinkapdf.com.

Your PDFs stay on your device

The compression tool processes PDF contents and filenames locally in your browser. It does not upload them to our servers or a payment provider. Keep your originals; results held in browser memory can be lost when you close or reload the page.

Information we handle

If you register, we store your account name, email address, password hash, language preference and account timestamps. Authentication uses session cookies and may record IP address and browser information. Anonymous download authorization uses a browser cookie. Download records contain an account or browser identifier, operation identifier, UTC date and allowance or credit usage; they do not contain your PDFs or filenames.

When payments are enabled, we store order references, plan, amount, currency, payment status, subscription periods and download credit records. Waffo Pancake handles hosted checkout and payment details. We do not store full payment card numbers or security codes. If you contact support, we receive the information you choose to include; please avoid sending confidential PDFs or payment card details.

Use, storage and sharing

We use this information to authenticate accounts, enforce download allowances, deliver purchased access, handle billing and support, prevent abuse and meet applicable obligations. Cloudflare hosts the website and account database and processes network requests for delivery and security. Basic Cloudflare website analytics measure visits and performance. Account cookies are used for authentication and allowances.

With your permission, we use Google Analytics to understand visits to our public pages. Optional analytics does not load until you accept it. Page addresses are sent without query strings or fragments; account and password-recovery pages are excluded. We do not send your PDF contents, filenames, account email or payment details to Google Analytics. You can change your choice using Cookie preferences on public pages. Essential account and download-allowance cookies work independently of this choice.

Service providers process the information needed to perform these functions, including Cloudflare for infrastructure and account verification or password-reset emails, Waffo Pancake for payments when enabled, and our email service for support correspondence. Their infrastructure may process information outside your country. We do not sell your personal information. Information may also be disclosed where required by law or necessary to investigate abuse and protect users.

Retention and your choices

We retain account, usage and billing records as needed to operate the service, resolve disputes, prevent abuse and comply with applicable obligations. Local PDF contents are not retained by our servers. You can ask to access, correct or delete account information by emailing support; we may verify account ownership. Some billing, security or legally required records may need to be retained. You can clear browser cookies, although this signs you out and affects browser-based allowances.

We use access controls and authentication to protect information, but no service can guarantee absolute security. This service is not directed at children under 13. Contact us about suspected unauthorized account access, a child's account or a privacy concern.

Policy updates

Changes will be published on this page with an updated date. Where applicable law requires additional notice or consent, we will provide it.
