This Cookie Policy explains how pdftoflip uses cookies and similar technologies on pdftoflip.com. Read it with the Privacy policy.
A cookie is a small text file stored on your device. Some cookies are essential. Others remember a choice such as language.
Cookies we use
| Name / type | Purpose | Duration |
|---|---|---|
| Session cookie (PHPSESSID) | Keeps you signed in and protects forms (CSRF). | Until you close the browser, unless “remember me” applies |
| site_lang | Remembers the site language you picked. | Up to about 13 months |
| Guest / fair-use cookie | Helps apply daily page limits for visitors who are not logged in. | Up to 1 year |
| Cloudflare Turnstile (if enabled) | Checks that a visitor is human before some guest actions. | As described by Cloudflare |
| Stripe (Premium checkout) | Needed to complete a paid subscription. | See Stripe’s cookie policy |
| Advertising cookies (only if ads are on) | If we show ads, the ad partner may set cookies. Premium members may see fewer or no ads. | Set by the ad partner |
Strictly necessary
Session, security, and checkout cookies are required to run accounts, uploads, and payments. The site cannot work correctly without them.
Preferences
The language cookie remembers your choice so pages stay in that language. You can change language at any time in the site language control.
Analytics and ads
If we add a usage-analytics cookie, we will list it here. If advertising is enabled, third-party ad scripts may set their own cookies. You can block those in your browser.
How to control cookies
- Use your browser settings to delete or block cookies. Blocking all cookies will sign you out and may stop uploads from working.
- Log out to end an account session.
- For Stripe or Cloudflare cookies, see those companies’ own help pages.
Changes
We will update this page if we add or remove cookies. Last updated: 26 August 2026.
