Waitlist privacy
Last updated 11 November 2026
This covers the early-access waitlist on grinzu.com only. Grinzu itself isn't open yet; when it is, it will have its own privacy policy, and you'll see it before you sign up.
What we collect
- Your email address.
- When you joined, and that you confirmed you're 18 or older.
- An optional campaign label in the link that brought you here (for example "instagram"), so we can see which campaigns bring signups. We don't use it to follow you across sites.
No advertising trackers and no Grinzu account are needed. We save your light or dark theme choice in your browser's local storage. We use cookieless usage analytics to understand overall site activity.
Our hosting and security services process technical information, such as your IP address and browser details, to deliver and protect the site and help block automated signups. Security services may use strictly necessary cookies for these checks.
What we use it for
Only to email you when your early-access invite is ready, and with launch news about Grinzu. We never sell your email or share it for anyone else's marketing. Every email has a way to unsubscribe.
Who handles it
We use hosting and data-storage providers to run this site and store the waitlist, security services to protect the form, and cookieless analytics services to understand overall site usage. They process information for those purposes.
When we send launch invitations, an email-delivery provider will receive your email address to deliver your invitation. Joining the waitlist does not send an email now.
How long we keep it
Until Grinzu opens and we've sent your invite, or until you ask us to remove it, whichever comes first. If you then create a Grinzu account, the app's own privacy policy applies to that account.
Your choices
To see, correct or delete what we hold, or to leave the waitlist, email hey@grinzu.com from the address you signed up with. We'll do it and reply within 7 days.
