Privacy Policy

Trentuno — iOS and Android

Last updated: 30 September 2026

Trentuno is made by VETERE APPS (Giovanni Vetere). This policy explains what the app does with information, and what it does not do. It covers the iOS and Android versions of Trentuno, which behave the same way in every respect described here except where a platform is named.

The short version: Trentuno has no account of mine and no server of mine. Your settings and your statistics live on your own device. Two things do leave it: what is needed to show advertising, which on iOS you can turn off by buying the ad-free upgrade, and — only if you choose to sign in — your achievements and scores, which go to Google Play Games on Android or Game Center on iOS.

Information I collect

None directly. There is nothing to sign up for, I run no server, and the app never asks you for your name, your email address or anything else about you.

If you sign in to Google Play Games or Game Center, that is an account you already have with Google or Apple, not one you create with me. I never see your password, your name or your email address.

Information stored on your device

Trentuno saves your settings — the card set, the table cloth, the card back, whether sounds are muted, whether knocking on a picture card is allowed — and your lifetime statistics, which are your wins, losses and the number of times you have made Trentuno.

This is kept in the app's own private storage on your device (UserDefaults and the keychain on iOS, shared preferences on Android). It is not sent to me or to anyone else. Deleting the app removes it.

On Android, this storage may be included in the automatic backup Google makes of your device if you have that switched on. That backup belongs to your Google account and is governed by Google's terms, not mine; I have no access to it.

Achievements and leaderboards

Trentuno offers achievements and leaderboards through Google Play Games on Android and Game Center on iOS.

Signing in is optional and the game is complete without it. If you decline, achievements and leaderboards are simply unavailable and nothing described in this section happens; everything else plays exactly as it would otherwise.

If you do sign in, the app sends the platform your player identifier — the one behind your gamertag — together with which achievements you have unlocked, your progress towards the ones you have not, and your total wins and total Trentunos as leaderboard scores. I never see your real name or your email address, and the app never asks the platform for your friends list.

If your Play Games or Game Center profile is public, your gamertag and your scores are visible to other players on the leaderboards. That is what a leaderboard is for, but it is your choice: setting your profile to private removes you from public leaderboards while leaving your own progress intact. You change this in your Play Games profile settings on Android, or in Game Center settings on iOS.

This data is held by Google or Apple against your platform profile. I keep no copy of it and cannot delete it for you — but you can, from your Play Games profile or your Google Account at https://myaccount.google.com, and from Game Center settings on iOS.

Google's handling of it is governed by the Google Privacy Policy: https://policies.google.com/privacy.

Advertising

Trentuno shows advertising supplied by Google AdMob: always on Android, and on iOS unless you have bought the ad-free upgrade. To do that, AdMob receives information from your device. It generally includes:

• your device's advertising identifier — the Advertising ID on Android, the Identifier for Advertisers on iOS
• your IP address, and the approximate location it implies
• your device type, operating system version and language
• which ads were shown to you, and whether you interacted with them

I do not receive any of this. What I see is an aggregate count of how many ads were shown and what they earned. I cannot identify you from it.

Trentuno is not directed at children, and the ads it requests are capped at a rating suitable for a teenage audience.

Google's own policy explains what it does with the data: https://policies.google.com/technologies/partner-sites. AdMob's description of the data it collects is at https://support.google.com/admob/answer/6128543.

Your choice about personalised ads

In the EEA, the UK and Switzerland, Trentuno shows you Google's consent form before it requests its first ad, and asks whether you agree to personalised advertising. If you say no, you will still see ads, but they will not be chosen using data about you.

You can change that answer at any time: open MORE OPTIONS in the app and choose AD CONSENT. The same form appears, with your current choices in it. This option is offered where the law requires the choice; elsewhere the button will tell you there is nothing to change.

Anywhere in the world, you can limit or reset the identifier that advertising is built on, using your device rather than the app:

• Android — Settings → Google → Ads, where you can delete the advertising ID outright or reset it to a new one
• iOS — Settings → Privacy & Security → Tracking, where you can withdraw the app's permission to track

Removing ads altogether

On iOS, the ad-free upgrade removes all advertising permanently. Once it is active the app makes no ad requests at all, and nothing described in this section continues to happen. The Android version does not offer it: there, every player sees advertising.

Purchases

The Android version of Trentuno sells nothing. It contains no in-app purchases, and Google Play's billing service is not part of it.

The iOS version offers one in-app purchase, which removes advertising. The purchase is handled entirely by Apple through the App Store. Your payment details go to Apple and never pass through the app; I never see your card number, your billing address or your name.

All I receive is confirmation that the purchase belongs to your App Store account, which is what the app checks on launch so that the upgrade follows you to a new device.

Refunds are handled by Apple under its own policies.

Notifications

If you allow it, Trentuno sends you a single reminder to come back and play, timed for three days after you last opened the app. It is scheduled by the app on your own device and its text is chosen on your device. Nothing is sent to a server, I do not send push notifications, and there is no list of anyone to send them to.

You can refuse the permission when it is asked for, or turn notifications off later in your device's settings for Trentuno. The game is unaffected either way.

Crash reports and diagnostics

Trentuno contains no analytics and no crash-reporting service of its own. I have not built in any tracking of how you play.

If your device is set to share crash and usage data with Google Play or Apple, those platforms may send me reports about crashes and performance. Those reports come to me already aggregated and anonymised, and describe the app rather than the person using it.

The Google Mobile Ads and Play Games libraries report their own health back to Google, which is why the app's Data safety listing on Google Play shows diagnostics being collected. That is those libraries describing themselves, not me watching how you play.

Children

Trentuno is a traditional card game for a general audience. It is not directed at children, and I do not knowingly collect personal information from children. Where the law sets a higher age than 13 for consent to data processing — as it does in parts of the European Economic Area, where it may be up to 16 — that higher age applies.

If you believe a child has provided personal information through this app, please get in touch and I will delete it.

Links out of the app

Advertisements and some menu items lead to websites I do not run. This policy does not cover them, and I have no control over what they do with your information. Their own policies apply once you leave.

Security

I keep as little as possible: nothing about you is stored on any server of mine, because there isn't one. Information that travels to Google for advertising, to Google Play Games or Game Center for achievements and scores, or to the App Store for purchases on iOS is protected in transit by those companies. No method of transmission over the internet is completely secure, and I cannot guarantee absolute security for information that is out of my hands.

Your rights

Because I hold no personal information about you, there is nothing of yours for me to show you, correct or delete.

For the data Google holds through AdMob, exercise your rights with Google directly, using the links above. The same applies to achievements and scores held by Google Play Games or Apple's Game Center — those are managed from your platform profile, not by me. To stop new data being collected, withdraw consent through MORE OPTIONS → AD CONSENT, reset or delete your advertising identifier in your device settings, decline or sign out of Play Games or Game Center, buy the ad-free upgrade on iOS, or uninstall the app.

Changes to this policy

I will update this page when the app changes in a way that affects it, and change the date at the top. Material changes will be described here rather than made quietly.

On 30 September 2026 the ad-free upgrade was taken out of the Android version, which now sells nothing, and this page was updated to say so. The app collects nothing it did not collect before.
