BrewBean Privacy Policy

Last updated: October 7, 2026 · Applies to BrewBean for iOS and Android.

BrewBean is a personal specialty coffee logbook: beans, grinders, waters, recipes, brews and tastings. This page explains which data the app processes, why, and how to delete it. It is written to be read in full in five minutes.

Who is responsible

BrewBean is developed and operated by Marcos Perez, in Argentina. Contact: brewbeancoffe@gmail.com.

What data is processed

Account data. When you sign in with Google or Apple, the identity provider gives us a user identifier, your name and your email address (Apple may hide it behind a relay alias). We use them to identify your account and show you who is signed in. Nobody else sees your email; your name is shown to others only when you share something (see below). If the provider gives no name, we use the part of your email before the @. We never ask for a password and never see one.

Content you create. Beans, roasters, farms, grinders and their calibration curves, waters, recipes, brews, sensory results, cupping sessions, Cup Tasters trainings, calibration sessions, photos of your bags and your settings (units, retention, default grinder and water). They are stored on your device and synced to our server so they are available on all your devices and are not lost if you change phones.

Minimal technical data. The server logs the requests it receives (date, path, response code) to operate the service and detect failures. Those logs contain neither the content of your data nor your credentials, and are kept only as long as needed to operate and diagnose the service.

What is shared with other people

By default, only you see your content. Someone else can see something of yours only in the four cases below, and every one of them starts with an action of yours.

Your username. To share a recipe or send an invitation you need to choose a public username (for example, @marcos). Anyone who knows it can type it to send you an invitation, and they see your name next to it. There is no user search or directory: a username can only be found by typing it in full.

Shared recipes. When you share a recipe, BrewBean creates a link and a code. Anyone who has them and uses the app sees a copy of the recipe as it was at that moment: the plan (method, dose, grind, temperature, pours and times), your notes and tags, the coffee, grinder and water as text, your username, your name and the statistics you choose to include. The link's web page, which requires no sign-in, shows only your username, the recipe name and the code. Anyone with the link or the code can import a copy into their account, labeled with your username and your name; that copy becomes theirs. You can revoke the link at any time from the same screen, and it stops working. Photos and your email are never shared.

Invitations. You can send someone, by their username, a recipe you have already shared or a calibration session you organize. They receive your username, your name and the name of the recipe or session, and can accept or decline it; you see which one they chose. While it is pending, you can withdraw it.

Panel calibration sessions. If you organize a session or join one (with its code or through an invitation), every participant sees the table's list with each person's name and username, and the details the organizer entered (name, place, notes). While the session is open nobody sees anyone else's scores, not even the organizer: only how far each person has progressed. When it closes, every participant gets the report with each taster's scores under their name and username, and can download it as a CSV file. That file leaves the app and stays with whoever downloads it. The notes you write on your score sheet are not shared. The organizer can remove a participant before the session closes, which deletes that person's scores.

What data is NOT processed

• We do not access your location: the app does not request that permission.
• We do not access your contacts, microphone or camera. The bag photos you choose to upload are the only images we process, and only when you upload them.
• We use no third-party analytics, advertising or advertising identifiers.
• There are no in-app purchases and no payment data.
• We do not sell, rent or share your data with third parties. Someone else sees something of yours only when you share it, as explained above.

Demo mode

The app can be used without an account, in demo mode, with sample data. In that mode nothing leaves your device: no account is created and no data is sent to the server.

Where and how it is stored

Your data is stored on your device and on our server, hosted at DigitalOcean. All communication between the app and the server is encrypted (TLS). Session credentials are kept in the operating system's protected storage. Access to your data is restricted to your account: the server returns each user their own content and, beyond that, only what other people shared with them. Photos are stored in a private bucket and served through short-lived signed URLs.

Third-party services

• Google Sign-In and Sign in with Apple, only to sign in. They are governed by Google's and Apple's privacy policies respectively.
• DigitalOcean, as the infrastructure provider running the server and the photo bucket.

How long it is kept

As long as your account exists. When you delete it, your data is removed from the server, including the recipe links you shared, the invitations you received, the calibration sessions you organized (with the scores of all their participants) and your scores in other people's sessions. What other people already received is not deleted: the recipe copies they imported, the CSV reports they downloaded and the invitations you sent them, which are withdrawn but keep your username and your name; server backups are kept for a limited period and rotated out. Data stored on your device is removed when you delete the account from the app or uninstall it.

How to delete your account and your data

From the app (recommended, immediate):

1. Open BrewBean and sign in with the account you want to delete.
2. Go to the More tab.
3. Tap Delete my account and confirm.

That removes the account and all its content from the server (beans, grinders, waters, recipes, brews, tastings, photos, shared links, invitations, calibration sessions and settings), signs you out on all your devices and wipes the local data on that phone. There is no grace period and no way to recover it afterwards.

If you can no longer sign in (you lost access to the Google or Apple account you used): write to brewbeancoffe@gmail.com from an address that lets us verify the account is yours. We delete the account and reply within 30 days.

This procedure cannot delete only part of your data while keeping the account; inside the app you can delete any bean, recipe, brew or tasting individually, and that deletion is synced to the server too.

Your rights

You can access all your data at any time from the app (More → Export my data produces a file with all your content, including the calibration sessions you took part in; closed ones with the table's full report), correct it by editing, and delete it as described above. For any other question about your data, write to the contact email.

Children

BrewBean is not directed at children under 13 and does not knowingly collect data from them. If you believe a child created an account, write to us and we will delete it.

Changes to this policy

If this policy changes, we update this page and the date in the header. Relevant changes are announced inside the app.
