Privacy policy

This page covers the Hourglow website and waitlist. Last updated 11 October 2026.

Who we are

Hourglow is a UK sleep and wellbeing app, currently pre-launch. For anything on this page, contact support@hourglow.co.uk — a person reads it.

What we collect, and why

If you join the waitlist: your email address, the phone platform you choose (iPhone/Android, optional), and the time you signed up.

Used for: one launch announcement email. Nothing else. No marketing sequence, no newsletter, and we never share or sell the list.

Lawful basis: your consent, given when you submit the form. You can withdraw it at any time (see "Your rights").

If you simply visit this site, we collect nothing: no analytics, no advertising trackers, and no cookies set by us.

Where it's stored

Waitlist entries are stored with Cloudflare, Inc., our hosting provider, in their Workers KV storage. Cloudflare operates a global network (including UK and EU data centres) and processes data under its standard data-protection terms. No other company receives your email address.

How long we keep it

Until shortly after the launch email is sent, or until you ask us to remove you — whichever comes first. After that, the list is deleted.

Your rights

Ask what we hold about you (it will be: one email address, maybe a platform choice, and a timestamp).
Ask us to delete it — email support@hourglow.co.uk and it's gone, usually the same day.
Complain to the UK regulator, the Information Commissioner's Office, if you're unhappy with how we've handled your data.

When the app launches

The app will have its own privacy policy, built on the same principle this site is: collect as little as possible, keep it on your device where we can, and never run ads or trackers.

Hourglow is a wellbeing app, not a medical product.
