YerbappPrivacy policy
Last updated: November 4, 2026
Yerbapp is an app to discover yerba mate: you scan the package and see its profile, reviews and prices. This page explains what data it keeps, why, and how to delete it. We don't sell data, we don't show ads and we don't use third-party analytics.
Without an account
You can use Yerbapp without signing up. In that case we don't store your name or email.
Scan photos: the package photo is sent to Yerbapp to recognize the yerba. If the “Use my photo to improve recognition of this yerba” box is checked (it is by default and you can uncheck it), the photo is added to that yerba's catalog, without your name. If you say it wasn't that yerba, the photo is withdrawn. Photos that don't look like a package are not published.
“None of these?”: if the scanner can't find your yerba and you tap “Send the photo”, we keep that photo (and whatever you write about which yerba it is) to add it to Yerbapp. Only the Yerbapp team sees it; if we use it, it goes into that yerba's catalog without your name, and if not, it's deleted after 60 days.
Statistics: we count visits, searches and scans in aggregate. To avoid counting the same person twice we use an encrypted fingerprint of the IP address (the IP itself is not stored). We also record where the visit came from (for example, Google or Instagram), with no personal data.
How the app is used: to improve it, we record which screens you open, which buttons you tap and what you search for, linked to your account if you signed in or to an anonymous code for your device if not. Only the Yerbapp team sees it, it isn't shared with anyone and it's deleted automatically after 3 days.
On your device: the app keeps your favorites, tried yerbas, achievements and language in the browser or app storage. They are removed if you clear the app's data.
With an account (Sign in with Google)
If you sign in with Google we receive your Google ID, email, name and profile picture. The app only shows a short name (for example, “Lucas L.”) and the picture.
We keep your progress (favorites, tried, achievements) so you don't lose it when you change phones, and what you post: reviews, replies, comments, reactions and mateadas (photos visible for 24 hours).
We use a cookie to keep you signed in (up to 180 days or until you sign out).
Notifications
If you turn on notifications, we store the delivery address provided by your browser or phone and which alerts you want. Alerts go through your device's notification service (Google, Apple or Mozilla). You can turn them off in My account or in your phone settings.
Camera
The app asks for the camera only to scan packages and barcodes, and to take mateada photos. Nothing is recorded or stored unless you send it.
Moderation
Published photos and texts go through automatic filters and may be held for review. We remove content that breaks the rules and may suspend accounts that break them.
How data is stored and who it is shared with
Data travels over encrypted connections (HTTPS) and is stored with backups. It is only shared with the services the app needs to work, such as Google for sign-in and your device's notification service. It is never sold or handed to third parties.
Deleting your account and data
In the app: My account → Delete my account. Your account, saved progress, reviews, replies, comments and mateadas are deleted immediately.
If you can't get into the app, email us from your Google account's address and we will delete it within 30 days.
Backups rotate automatically and deleted data is gone from them within 30 days. Aggregate statistics (which identify no one) are kept.
Children
Yerbapp is not directed at children under 13 and does not knowingly collect their data.
Changes
If we change this policy, we update the date above. If the change is important, we announce it in the app.
