Cookie Statement
Last updated: September 28, 2026
Koutei PDF uses only the cookies needed to keep you signed in, plus one setting saved in your browser to remember your colour theme. We don't use advertising, analytics or tracking cookies, so we don't show a cookie banner.

The sign-in cookies are strictly necessary: without them you can't stay signed in, so they don't need your consent. They are only set once you sign in or start signing in.
2. Other companies
When you open checkout to buy a paid plan, the checkout page loads Paddle.js from Paddle, and Paddle may set its own cookies or similar storage there to run the checkout and prevent fraud, as its privacy policy describes. If you choose Sign in with Google, Google uses its own cookies on its own sign-in pages. If you signed in with Google, your profile picture loads from Google's servers.
3. Your choices
You can clear or block cookies in your browser settings. If you block the sign-in cookies, you won't be able to stay signed in. Clearing your browser storage resets your theme to the default.
4. Changes
If we ever add cookies that aren't strictly necessary, such as analytics, we will update this page first and ask for your consent where the law requires it. Questions: privacy@kouteisystems.com. See also our Privacy Policy.
