Cookie policy
Last updated: October 20, 2026
This policy explains which cookies and similar technologies eFlyPDF uses, and how you can control them. The short version: only what is needed.
1. What is a cookie?
A cookie is a small text file stored by your browser when you visit a website. It lets the site remember information, such as your session or your language.
Similar technologies, such as your browser's local storage, work in the same way. This policy covers them too.
2. Strictly necessary cookies
These cookies are essential for the service to work. They do not require your consent.
| Name | Purpose | Duration |
|---|---|---|
| sb-…-auth-token | Keeps you signed in to your account (Supabase authentication session) | Session, until you sign out |
| NEXT_LOCALE | Remembers the language you chose | 1 year (to be checked) |
| Cloudflare Turnstile cookies | Anti-bot security check. Set only on the contact form, and only when this protection is enabled | Short duration set by Cloudflare |
3. No tracking
We use no advertising trackers and, by default, no third-party audience measurement.
If we add audience measurement one day, it will be minimal and subject to your consent where the law requires it. This policy will be updated first.
4. Advertising
An advertising banner may one day be shown on free plans. It is currently disabled. If it is enabled, it will be displayed without trackers, or only after your explicit consent, and this policy will be updated first.
5. Local storage in your browser
We store some preferences directly in your browser, such as the display currency or files waiting to be processed.
This information stays on your device. It is never sent to us.
6. Managing cookies
You can view and delete cookies at any time from your browser settings.
If you block strictly necessary cookies, you will not be able to sign in, and some features may not work.
7. Changes
We will update this policy if we change the cookies we use. For more on how we handle your data, see the privacy policy (/en/privacy).
