Privacy

We keep as little about you as we can, use it only to warn you about your journeys, and never sell it.

Who we are

Know Before is made by Doccrs Digital Ltd., registered in England and Wales, company number 16338795. We’re the data controller for the information described here. We’re registered with the Information Commissioner’s Office, registration number ZC270907.

To contact us about your information, email support@knowbefore.co.uk, use the contact form, or write to Doccrs Digital Ltd., No1 Business Centre, 1 Alvin Street, Gloucester GL1 3EJ, United Kingdom.

If you join the pilot on this website

• We keep your email address, the area you chose and which journeys you ticked.
• We use them only to invite you to the pilot and to see which areas people are in. We send no marketing.
• We keep them until the pilot ends or you ask us to delete them, whichever comes first.
• Our legal basis is your consent, which you can withdraw at any time by asking us to delete your sign-up.

If you contact us

• We keep your message, your email address and your name if you give it, so we can reply.
• We delete messages a year after we’ve dealt with them, unless we need them to show we handled a deletion request.

If you use the app

• You don’t need an account, an email or a phone number. The app signs you in anonymously.
• If you tell the app your first name, we keep it so the app can greet you. It’s optional.
• We keep the journeys you save: the places at each end, the route, the days and the times. We need these to check for roadworks on your way, which is the service you asked for.
• We only use your location if you tap “Use my current location”, to work out your route. We don’t track where you go.
• If you turn on alerts, we keep a notification token so we can send them, and a record of which alerts we sent so we don’t repeat them.
• The app has no adverts, no ad trackers and no analytics.

Where it’s kept and who else sees it

Everything is stored by Supabase in their London region. The website is hosted by Vercel. When you search for a place, the text you type goes to Google. Postcodes are looked up with postcodes.io, and routes are worked out with OpenRouteService, which receive the start and end of a route but nothing else about you. Notifications are delivered through Apple and Google’s notification services.

Your rights

You can ask for a copy of your information, ask us to correct it, or ask us to delete it. Deleting a journey in the app deletes it from our servers, and “Delete all my data” on the app’s Alerts tab deletes everything we hold for you. For anything else, such as a pilot sign-up, send us a request and we’ll complete it within one month.

If you’re unhappy with how we’ve handled your information, you can complain to the Information Commissioner’s Office.
