Privacy policy
Last updated: 8 October 2026
Brewcue is a coffee brewing app. Brewing, recipes you create, your journal and sharing by link work on your phone without an account. This policy explains what leaves your phone and why.
Stored on your phone
- Your recipes, beans, journal entries, photos, notes and settings.
- Whether you bought Remove ads, and whether your account has Brewcue Pro.
Without an account we never receive this data, and uninstalling the app removes it. With an account, a copy is synced as described below; photos and settings always stay on your phone.
Your account (optional)
You only need an account for Community (browsing, saving, posting and rating recipes), to sync your data between your phones, and to buy Brewcue Pro. If you sign in with Google:
- Firebase Authentication keeps your account ID, your email address and the sign-in provider. Your email is shown only to you in the app; it is never public.
- Cloud Firestore keeps your handle and optional display name, which are public to other signed-in users, the date you created them, and the date you accepted the Terms.
- Cloud Firestore also keeps a copy of your beans and blends, grinders and grind settings, journal entries (without photos), your recipes and notes, so they stay the same on every phone you sign in on. Only you can read this copy.
- A recipe you post to Community is public to other signed-in users, with your handle. Unless you turn off Include bean & setup, the post also shows the bean (name, roaster, origin, process, roast, notes) and the settings you brewed it with (grinder model and setting, temperature, dose).
- If you buy Brewcue Pro, the purchase is made in Google Play with a one-way code derived from your account ID (not the ID itself). Our server checks the purchase with Google Play and keeps, with your account, that you have Pro, the Google Play order number and the purchase date. We never receive your payment details.
- We do not copy your Google profile photo or name.
This data is stored by Google Cloud in Singapore (asia-southeast1).
Shared links
A shared recipe link contains the recipe itself, and the name, result, bean and settings you chose to include. The data is in the part of the link after #, which browsers do not send to our server.
Usage, crash and ads data
- Google Analytics for Firebase: anonymous usage events (for example, that a brew finished). It is turned on only where the law does not require your consent first, or after you give it.
- Firebase Crashlytics: crash reports with device model and app version.
- Firebase Remote Config and App Check: settings for the app, and a check that requests come from the genuine app.
- Google AdMob: shows ads on some screens, using the advertising ID of your device. Where required, we ask for your consent first (Google's consent form), and on iOS the system asks for permission to track.
See Google's Privacy Policy for how Google handles this data.
Deleting your data
In the app: Settings → your account → Delete account. This removes your account, your handle, your synced copy, your Pro record and everything you posted or rated. A Pro purchase stays in your Google Play account; you can restore it on a new Brewcue account. Signing out keeps your data on the phone and stops syncing. You can also ask us by email.
Children
Brewcue is not directed at children under 13, and accounts are not intended for them.
Changes
We will update this page when something changes and, for important changes, tell you in the app.
