Privacy
Last updated 10 November 2026.
BrewBat is run by James Torr in the United Kingdom, who looks after your data. Questions, or anything below you'd like done, go to beer@brewbat.com.
What we keep
- Your account: email address, username, and your password (scrambled, never readable).
- Your brewing: recipes, kit and settings, readings, stock, and the town you pick for your tap water (its rough location).
- Sign-in and use: when you last signed in and used the app, and the session cookie that keeps you signed in.
- If you pay: whether you're on Brewer and a reference to your subscription. Your card and billing details stay with Polar; we never see them.
Why
To run BrewBat for you: your recipes, your numbers, your plan. We email you only about your account (sign-in links, confirming your address). We don't sell your data, show ads, or use tracking or advertising cookies.
Who else sees it
- Other brewers: only recipes and a profile you choose to make public.
- Polar (polar.sh), our payment provider and the seller of subscriptions, gets your email and payment details when you pay. Its privacy policy covers that.
- Our email service sends BrewBat's emails, so it handles your email address.
- OpenStreetMap: when you search for your town or open a map, your browser asks OpenStreetMap for the place or the map tiles.
BrewBat's server and database are in the United Kingdom.
How long
As long as you have an account. Ask us to close it and we'll delete your account and recipes within 30 days, apart from anything we must keep by law. Public recipes others have already copied stay as their copies.
Your rights
You can see, correct, take or delete your data. Settings → Account has a full backup of everything, and your recipes as BeerXML. For anything else, or to object to how we use your data, write to us. If you're not happy with our answer, you can complain to the Information Commissioner's Office (ico.org.uk).
