Privacy notice
Draft · last updated 10 November 2026Draft. Email alerts are not open yet, so nothing described under "Email alerts" is collected today. Details marked like this are still to be confirmed before launch.
The short version
- Using this website sends us nothing about you. Postcode lookups, your alert settings and the preparedness check all stay in your browser.
- If you sign up for email alerts, we keep your email address, your postcode district and your alert choices, and use them only to send the alerts you asked for.
- We do not sell or share your details, show adverts that track you, or build a profile of you.
- You can unsubscribe with one click from any email, and we then delete your details.
Who we are
PostcodeAlert is run by [name of the person or company responsible], who is the data controller. For anything about your data, write to [privacy contact email]. We are registered with the Information Commissioner's Office [registration number].
Using the website
You do not need an account, and we do not use cookies or analytics that identify you.
- Postcode lookup. The page already contains the information for every district, and your browser picks out yours. The postcode you type is not sent to us.
- Remembered district and alert settings. Your browser remembers the last district you checked and the alert settings you saved, including an email address if you typed one into the settings box, so the page can open on your area. They are stored on your device only. "Whole UK" forgets the district; clearing your browser's site data removes both.
- Preparedness check. Your answers, including anything about health or medical equipment, are used inside your browser to work out your list. They are never sent to us or saved, and are gone when you close the page.
- Server logs. Like any website, our hosting provider [hosting provider] records technical details of each request, such as IP address, time and page, to keep the site running and secure. We keep these for no more than 30 days and do not use them to identify you.
Email alerts
If you sign up, we collect:
- your email address;
- your postcode district (the first half of your postcode, such as OX1), not your full postcode or address;
- which alerts you chose and at what level;
- when you signed up and when you confirmed, as our record of your consent.
Why, and our legal basis. We use these only to send the alerts you asked for. Our legal basis is your consent, which you give by signing up and clicking the link in our confirmation email. You can withdraw it at any time by unsubscribing.
Confirmation. We send one email asking you to confirm. If you do not confirm within 7 days, we delete the sign-up.
Who else handles your details. Our email provider, [email provider], stores the list and sends the emails on our behalf under a data processing agreement. It holds the data in [the UK or EU]. Nobody else receives your details.
How long we keep them. Until you unsubscribe, when your details are deleted. We also remove addresses that stop accepting email, and ask you to re-confirm if you have not opened an alert for 24 months.
What the emails contain. Alerts for your district and links to change your settings or unsubscribe. They do not contain advertising unless you separately ask to receive it.
Links to shops
Some product links on the preparedness check are marked "(Ad)". If you follow one, you leave this site and the retailer's own privacy policy applies. The retailer may record that you arrived from us so that we can be paid a commission. We do not tell the retailer anything about you, and we never learn who bought what.
Your rights
You can ask us for a copy of what we hold about you, to correct it, to delete it, or to stop using it. Write to [privacy contact email] and we will reply within one month. Unsubscribing deletes your details without needing to ask.
If you are unhappy with how we have handled your data, you can complain to the Information Commissioner's Office at ico.org.uk or on 0303 123 1113.
Not an official warning service
PostcodeAlert brings together public information to help you prepare. It does not replace official warnings. Alerts can be late or fail to arrive. In an emergency call 999, and follow the Environment Agency, your network operator and the emergency services.
Changes to this notice
If we change what we collect or why, we will update this page and, if you are subscribed, tell you by email before the change takes effect.
