Privacy, in plain English

Look Up is free, has no ads, sets no cookies and needs no account. Here’s everything it does with data.

Your location

If you press Use my location, your browser asks first. The position is rounded to about 1 km in your browser before it’s sent, and it’s only used to work out your sky. Postcodes you type are looked up on our own server against Ordnance Survey open data; they aren’t sent anywhere else or stored.

Visit counts

We count visits ourselves, without cookies or any third-party analytics. For each page view we add one to a daily total for that page, the website that sent you (for example “google.com” or “direct”) and your country. To count how many different people visited each day we keep a one-way scrambled code made from your IP address, browser and the date, with a secret that changes the result every day. These codes can’t be turned back into an IP address, can’t follow you from one day to the next, and are deleted once the day is over (normally within a day or two). We also count button presses such as “Share” or “Add to calendar” as anonymous daily totals.

Email heads-ups

Not yet open. Email sign-up is paused, so we don’t collect any email addresses at the moment. The rest of this section explains what will happen once it opens.

If you sign up, we store your email address, the town you were looking at, or your position rounded to about 1 km (so the timing suits you), which alerts you asked for, the page you signed up on, the date, the exact wording you agreed to, and a scrambled code made from your IP address that we use only to stop spam sign-ups.

• Nothing is sent yet. Before any heads-up, you’ll get one email asking you to confirm. If you don’t confirm, you won’t hear from us again and your address is deleted.
• At most a few emails a month, only about sky events. Every one has a one-click unsubscribe.
• We never sell, rent or share your address. It’s stored in a Cloudflare D1 database, used only for these emails.
• Our legal basis is your consent (UK GDPR Article 6(1)(a)), which you can withdraw at any time.

Who runs the site

Look Up is hosted on Cloudflare, which processes requests to deliver the site (its own logs are covered by Cloudflare’s privacy policy). Weather comes from MET Norway and space-weather data from NOAA; our server asks MET Norway for the forecast at a position rounded to about 1 km, and nothing that identifies you goes with it.

Your rights
