Cookies & storage

Last updated: October 24, 2026 · eoptima.net/en/cookies/

No tracking, analytics, or advertising cookies. eOptima only uses storage that is technically necessary for the service (§ 25(2) no. 2 TDDDG, German Telecommunications Digital Services Data Protection Act). That's why we don't ask for consent either.

There's currently nothing to configure: eOptima only uses storage that's needed for sign-in, security, and your color scheme. We don't use analytics or advertising cookies.

You can change your color scheme at any time using the sun/moon icon in the top right, or delete it in your browser.
