Privacy policy

This covers the Mosaic waitlist website. Last updated 14 November 2026.

What we collect

When you join the waitlist we keep:

• your email address
• the city you type in
• the time you joined
• your personal invite code, and the invite code of the friend who sent you, if there was one

We don't ask for your name, phone number or anything else, and we don't use tracking cookies.

What we use it for

• to email you when Mosaic opens in your city
• to show you your place in line and how close your city is to opening
• to move you up the line when friends join with your link
• to decide which cities to open first

We won't send you marketing emails, sell your details or share them with other companies to market to you. If we ever want to send you more than launch news, we'll ask first.

Our reason for using it

Under UK data protection law (UK GDPR), we rely on your consent, which you give by joining. You can take it back at any time by asking us to delete your details.

Where it's kept

Your details are stored in a Google Sheet that only the Mosaic team can open (Google is our storage provider). This website is hosted by Cloudflare. Both may process data outside the UK under their standard data protection terms.

What's saved in your browser

So you see your place in line when you come back, this site saves your invite code in your browser's local storage. If you arrived through a friend's link, their invite code is kept for that visit only. Clearing your browser data removes both.

How long we keep it

We keep your details until Mosaic launches in your city and for up to 12 months after, unless you ask us to delete them sooner. If you join the app, the app's own privacy policy takes over.

Your rights

You can ask to see the details we hold about you, correct them or have them deleted. Email the Mosaic team and we'll reply within one month.

If you're unhappy with how we've handled your data, you can complain to the Information Commissioner's Office at ico.org.uk.
