What we do not set
No advertising cookies. No analytics cookies. No pixels from Meta, Google Ads, TikTok or anyone else. No cross-site tracking of any kind.
This is not a temporary state of affairs we plan to change quietly. If it ever changes, a banner appears and this page changes first.
What is stored in your browser
Two values in local storage — technically not cookies, but you deserve to know about them either way:
zyvavo-theme — light or dark. Read before the page paints so it does not flash the wrong colour at you.
zyvavo-account — your initials, so the navigation can show your avatar without loading the whole authentication library on every marketing page.
Neither is ever sent to us. Both disappear when you clear your browser data.
The sign-in token
When you sign in, Firebase Authentication stores a token in your browser so you stay signed in between visits. That is strictly necessary for the account to work — without it you would be signed out on every page.
It identifies your session to Firebase and nothing else. It does not follow you to other websites.
Turning it off
Blocking storage for this site in your browser settings will work. The theme will reset to light on every visit and you will not be able to stay signed in, but nothing else breaks — the tools that run in your browser will still run.
Written by the person who built the software, not copied from a template — so if something here does not match what actually happens, that is a bug and we want to hear about it: support@zyvavo.com.
