Common questions about how xenoa works.
No. There are no accounts anywhere on xenoa. A poll, pad, draw, or scoreboard is just a random link; anyone with that link can use it.
If it's something you or your group have used, no: links don't expire and nothing gets cleaned up just for being old. The only content that might be removed is stuff that was never really used in the first place, or is being used abusively.
Yes. Whoever created a poll, pad, draw, or scoreboard gets a private admin (or edit) link alongside the public one, and that page has a delete option.
There's no automated way to recover it, since it isn't tied to an email address or account. Save it somewhere safe as soon as you create something; if you're stuck, you can always ask through the contact page.
No. The only thing xenoa remembers about you is an anonymous browser cookie that distinguishes "you" from other people inside one specific poll, pad, draw, or scoreboard (so your votes or claims don't get mixed up with anyone else's). It isn't a name, email, or identity of any kind.
No. Only the general tool pages (like the "start a new poll" page) are indexable. Every link to an actual poll, pad, draw, or scoreboard is excluded from search engines and crawlers.
