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 [email protected] — 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.

If you subscribe to Hourglow Plus, payment is taken by Stripe, Inc., our payment processor. Stripe receives the details you enter at checkout (card number, name, email) and processes them under its own privacy policy; your card details never touch our servers. We store only your subscription status — whether Plus is on or off.

If you choose to leave a review inside the app, we store the words you type, the rating you pick, and the first name you give (if any) with Cloudflare. Reviews are read by the founder and are only published on this website if you ticked the box agreeing to that — first name only, never edited. You can ask for a review to be removed at any time via [email protected].

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 [email protected] 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.
