Venn
Privacy
Venn is built to know as little about you as possible. There are no accounts, no cookies, no ads and nothing that follows you around. This page explains exactly what is stored.
What we store
- Polls: the title, place, note, organizer name, time zone and proposed dates and times.
- Responses: the name each person types and their answers. If the organizer hides names or answers, other guests don't receive them at all; only the organizer does.
- Your email, only if the organizer asks everyone for one: it's stored with your answer and shown only to the organizer. It's deleted when you remove your answer or the organizer deletes the poll.
- Otherwise, not your email, even if you ask for a copy of your answer: the address is used to send that one email, then dropped. It isn't stored with the poll or shown to anyone.
- Notification settings, if the organizer turns them on: an email address or a webhook URL. These are never shown to people answering the poll.
-
Secrets: only a SHA-256 hash of each organizer and edit link secret. The secret itself is in the part of the
link after
#, which browsers never send to the server.
What we don't collect
- No accounts, passwords or sign-ups.
- No cookies, tracking pixels, third-party analytics or advertising.
- No calendar data. Check my calendar runs in your browser. Google and Microsoft are asked only for busy/free times, the sign-in token never reaches our server, and calendar files are never uploaded.
Anonymous usage counts
To learn what to improve, Venn counts how it's used, one number per day: for example, how many polls were created to vote on dinner times, or how many people answered a poll. Nothing about you or your poll is stored with those numbers: no names, titles, links, emails, IP addresses or device details, and nothing that connects one count to another. If your browser sends Global Privacy Control or Do Not Track, nothing is counted.
Your browser saves which polls you organized or answered (in local storage on your device) so you can come back to them. You can clear it at any time in your browser settings.
Who processes data
- Cloudflare hosts the site and the database.
- Cloudflare Email (or Resend) sends emails: notifications, only to the address the organizer gave, and copies of an answer, only to the address the person gave.
We never sell or share poll data with anyone else.
How long we keep it, and how to delete it
Polls are kept until the organizer deletes them. The organizer can delete the whole poll or anyone's response. Anyone can remove their own response. Every notification email has a one-click unsubscribe link.
