Privacy Policy

Last updated: October 24, 2026

PrestoEvent is a free service of PrestoBiz (Zing! Inc.). We take your privacy seriously. We do not sell or rent your information, and we never show ads on your sign-up pages. This policy explains what we collect and why.

Two kinds of people use PrestoEvent, and we treat them differently:

  • Organizers create an account and build sign-up sheets.
  • Participants sign up on someone's sheet. They have no account and need no password.

What we collect

If you create an account (organizers)

  • Your email address, and your name and organization if you give them.
  • Your password, stored only as a one-way hash — we cannot read it.
  • If you use “Continue with Google”: Google’s account identifier for you, your email address, and the name on your Google account. We never receive your Google password.
  • The internet address (IP) your account was created from, and the times you sign in, to limit abuse of a free service.
  • Everything you put in a sign-up sheet: its title, description, dates, times, location, slots, questions, pictures and any logo you upload.
  • Messages you send to the people who signed up: what you wrote, when, which of them it went to, and whether each one was delivered. Your contact email goes with each message, so people can reply to you.

If you sign up on someone’s sheet (participants)

  • Your name and email address, a phone number if you give one, your answers to the organizer’s questions, and any note you add.
  • The internet address (IP) you signed up from, kept to stop automated abuse.
  • We email you a confirmation with a private link that lets you change or cancel your sign-up without an account.
  • The organizer can send a message to the people who signed up, and we deliver it to your email address. Each message says which organizer wrote it and which sign-up it is about. It goes to you alone: nobody else who signed up sees your address. If you choose “Stop messages about this sign-up” or report a message, we record that.

Your name may appear on the sign-up page if the organizer chooses to show who signed up, and then only as your first name and last initial — “Priya S.” The form tells you before you submit. Your email address, phone number and answers are never shown publicly; they go to the organizer.

Everyone

  • Ordinary web server logs: the page requested, the time, the IP address and the browser.
  • Cookies we set to keep you signed in, to protect forms against cross-site attacks, to show a one-time message, to return you to the template you chose, and to note your device’s timezone so a new sign-up starts in it. We set no advertising cookies and allow no advertising networks on these pages.

How we use it

  • To run the service: show sign-up pages, take sign-ups, and email confirmations, reminders and sign-in links.
  • To deliver an organizer’s messages to the people on their sign-up sheet. We send these for the organizer, only to people who signed up on that sheet, and only about that sign-up — never advertising of ours. Every message has a link to stop messages about that sign-up, or to report it to us.
  • To keep it working and honest: rate limits, the sign-up CAPTCHA, and investigating abuse reports.
  • To reach you about your account when we must.

Sign-up sheets are shared by their link and are not indexed by search engines. An organizer’s page is public to anyone holding the link.

Who else sees it

We never sell or rent information, and we never share participants’ details with anyone but the organizer of the sheet they signed up on. We use a small number of providers to run the service:

  • Email delivery — to send confirmations, reminders, sign-in links and organizers’ messages.
  • Cloudflare Turnstile — the “are you a person” check on account creation.
  • Google — only if you choose “Continue with Google”.
  • Our hosting provider — the server the service runs on.

We may also disclose information when the law requires it — a subpoena, a court order or legal process — or when we investigate a violation of our Service Terms.

Support staff, and being told about it

PrestoBiz support staff can open your account to help you, with a reason recorded every time. A banner shows on every page for as long as they are looking. Sessions are read-only unless a senior administrator allows a change, every change is recorded, and we email you when a session ends, whether or not anything changed. Staff never see your password.

Separately from that, staff can read any sign-up sheet, including one you have not published yet. A sign-up sheet is a page made to be handed to other people, so we treat it as public rather than private, and we check them because PrestoEvent is free for anyone to join — which makes it a target for people who would use it to mislead or spam others. Reading a sheet is not entering your account: no one is signed in as you, nothing is changed, and it is not what the email above is about. Your account details, your password and the contact details of people who signed up are not part of this.

Staff can also read the messages organizers send, so that we can act on a report of spam or abuse. The staff console shows what each message said and how many people it reached, not who it went to; only a session opened in an organizer’s account, as above, shows what the organizer sees. If you report a message, staff see your email address with the report, so that we can follow up.

Keeping and deleting

  • Participants can cancel a sign-up at any time with the private link in their confirmation email. The organizer can also remove them.
  • Organizers can delete a sign-up sheet, which hides it from everyone.
  • Anyone who gets an organizer’s message can stop further messages about that sign-up with the link at the foot of it, and turn them back on from the same page. “This wasn’t me” on that page cancels every sign-up the address holds and stops us emailing it at all.
  • We keep each message, and who it went to, for as long as the sign-up sheet it was sent from.
  • We keep account and sign-up information until you ask us to remove it. Write to [email protected] and we will.
  • Backups are kept for a limited period, so deleted information may persist in them briefly.

Security

The whole site is served over HTTPS. Passwords are stored as one-way hashes. Sign-in links and private confirmation links are stored only as hashes, expire, and work once. Staff accounts require a password and a second factor.

Children

PrestoEvent is for adults — parents, teachers, coaches and volunteers. We do not knowingly collect information from children under 13. If you believe a child has given us information, write to [email protected] and we will remove it.

Changes

We may amend this policy from time to time. The current version is always on this page, with the date it was last changed at the top.
