Tantea is a free app for keeping score in domino games. This policy
explains what data we collect, why, and what control you have over it.
Plain language, no unnecessary legalese.
The essentials: Tantea works 100% on your phone with no
account required. Creating a profile is entirely optional
and lets you share your games across your devices and with other players,
and appear on the leaderboard. We only send data to our server if you
create a profile.
1. Data on your device (no account)
If you don't create a profile, this data never leaves your phone:
Game history (team names, scores, dates).
Your preferences (theme, sounds, haptics, bonus values).
A random anonymous device identifier (it contains no name, email, phone, or anything identifiable).
2. Data if you create a profile (optional)
When you create your profile we generate a unique identifier on your phone and store on our server:
Your name (the one you use at the table).
Your email — optional and unverified. We only use it to help you recover your profile if you change phones. You can leave it blank.
Your country — auto-detected from your phone's language; you can change it. Used for the national leaderboard.
Your province or city — optional, chosen by you. Used for the local leaderboard.
When you play a game in which at least one player has a profile, that
game's result (teams, scores, bonuses, date, and country) is
stored permanently on our server and delivered to the
apps of the players-with-profile who took part. We use those results to
compute statistics and leaderboards (national, by city, and global). Games
with players without a profile ("Us", "Them"…) stay only
on the scorekeeper's phone.
The QR code you share contains only your identifier and
your name. It never includes your email or location.
3. Anonymous usage statistics
Only if you have the "Anonymous statistics" toggle enabled in Settings do
we send anonymous usage events (e.g. "a game started", "a game was won").
They never include team names or personal content, and are not tied to
your profile.
4. Data we do not collect
Your phone number or other contact info (email is optional and provided by you).
Your precise location (GPS). You choose the country/city for the leaderboard; we do not track your position.
Your contacts list or photo gallery.
Biometric information.
We never sell your data or use it for third-party advertising.
5. Where data lives & third parties
Profile and game data are stored in our own database
(MongoDB Atlas) via our server hosted on
Railway. These are infrastructure providers that store
the data on our behalf; we do not use them to profile you nor share your
data with third parties.
Future versions may integrate, with prior notice in this policy:
AI-powered photo counting (optional) — to count pips from a photo; the image would be processed in memory and discarded, not stored.
Advertising — to keep the app free; we'll ask for your explicit permission (App Tracking Transparency on iOS) before any tracking.
6. Your rights
Don't create a profile: the whole app works without an account, so nothing leaves your phone.
Turn off anonymous statistics: Settings → "Anonymous statistics" → off.
Delete your account and all your server data (profile, games, and statistics): email us at knowelltechnology@gmail.com and we'll erase it. The app also includes/will include an option to delete your account directly.
Delete local data: uninstall the app.
7. Children
Tantea is not directed at children under 13, although its content is
suitable for all audiences. We do not knowingly collect data from minors.
If you believe a minor sent us data without parental consent, contact us
and we will delete it.
8. Changes to this policy
If we update this policy materially, we'll change the date above and,
depending on the change, show an in-app notice.
Quick summary: Tantea is 100% free and works without an
account. If you create a profile (optional), we store your name, optional
email, country, and city, plus the games you take part in, to sync with
other players and build the leaderboards. Email and location never go in
your QR. You can delete your account and all your data anytime. No data
selling.
