Cookie Policy

Cookies are small files stored on your device when you visit a site; similar technologies include browser localStorage and sessionStorage. This policy explains which we use and why, and supplements our Privacy Policy.

Today PDFglyph uses only what is strictly necessary to run the app:

• Session / refresh cookie (strictly necessary): a secure, httpOnly cookie that keeps you signed in and protects your session. Without it you cannot stay logged in. Duration: up to 30 days.
• Functional localStorage (strictly necessary for the feature): stores your theme choice and onboarding progress in your browser. It is not sent to our servers.

We use no analytics, advertising or cross-site tracking cookies. Our public pages do carry cookieless audience measurement (Umami Cloud, EU region): it sets no cookie and stores nothing on your device, so there is nothing here to consent to or turn off. Visitors are counted using a temporary identifier the provider derives from your IP address and browser; it is not used to identify you, and it does not follow you to other sites. It does not run inside the signed-in app.

Under the ePrivacy rules and the GDPR, strictly-necessary cookies do not require consent; we use them on the basis of our legitimate interest in providing a working, secure service. Our audience measurement neither stores nor reads anything on your device, so the consent rule for cookies does not apply to it; the aggregate statistics it produces rest on our legitimate interest, Article 6(1)(f), in understanding which pages are useful. If we later introduce analytics or marketing cookies, we will request your consent first through a cookie banner, set non-essential cookies only after you agree, let you accept or reject by category, and let you withdraw consent at any time.

You can delete or block cookies through your browser settings; blocking the session cookie will sign you out and may break core features. If we introduce non-essential cookies, you will be able to change your choices at any time via a cookie preferences control.

We will update this policy if our use of cookies changes, with a new date and reasonable notice for material changes.
