Privacy Notice

Last updated: 9 November 2026

Who we are

Polymonial is a product of My Red Crayons Ltd, registered in England and Wales (company 14137691), Nottingham. We are the data controller. Questions: talk to us (choose Privacy & Data Request).

What we collect

If you join the waiting list: your email address, first name, any event code you enter, the dates you joined and confirmed, and your number on the list.

If you use the contact form: your name, email address, organisation, message and your role, if you give one.

We never ask for payment details or sensitive data. Analytics run only if you agree (see our cookie notice).

Why, and our lawful basis

To invite you when your place comes up, send the updates you opted in to, and apply any event discount, based on your consent, given when you confirm by email.

To keep our forms secure and honour unsubscribes, based on our legitimate interests.

To reply to messages you send us, based on our legitimate interests.

Who we share it with

We never sell your data. Cloudflare hosts the site and holds the waiting list in its EU region. Postmark sends our emails from the US. Both transfers are covered by standard contractual clauses (with the UK Addendum).

How long we keep it

Until you unsubscribe or we close the waiting list. Unconfirmed sign-ups are deleted after about a week. Deleted data can stay in backups for up to 30 days.

Contact messages: as long as needed to deal with them, then deleted.

Your rights

You can access, correct, delete, restrict, object to or take a copy of your data, and withdraw consent at any time. To do so, talk to us; we reply within one month. You can also complain to the ICO (ico.org.uk).

Changes

We’ll update this notice when our processing changes, and email you before any material change.
