Anagramme chrono is a word game with two modes, and how your data is handled depends entirely on which one you play. The campaign is offline: nothing leaves your device, no account exists. The online duel publishes a round you have just played so that another player can take it on: this requires an anonymous account and sends a small set of game data, described in detail below. There is no tracker and no in-app purchase, and nothing is sold. The only advertising is optional: in the hint shop, you can choose to watch a short Google AdMob video to earn a hint (see “Optional advertising”).
The online mode is an addition, never a toll gate: the app remains fully playable offline and without an account.
Most of your data never leaves the phone. It is stored in the app's private storage (shared_preferences, on Android):
The French dictionary (85,535 words) is bundled inside the app: playing the campaign requires no connection at all.
Opening the online duel screen creates an anonymous account through Firebase Authentication (Google). "Anonymous" in the technical sense: it does not sign you in to any existing account. The app asks for no name, no email address, no password and no phone number, and does not connect to your Google account. This account is a random identifier, specific to your installation, used only to know which round is yours and to avoid pitting you against yourself.
The connection is lazy: it happens only when you open that screen. As long as you do not open it, no account is created.
When you publish a round, or when you answer another player's round, the app sends exactly this:
Nothing else. No contact details, no location, no device identifier (the optional advertising described below follows its own rules), no freely written content: the words transmitted are French dictionary words you formed from the letters of the draw. A round you abandon is never published.
Your nickname is visible to players who take on your round. It is a free field: we recommend not putting your real name or any identifying information in it.
Shared rounds are stored in Cloud Firestore (Google), in the
anagramme-chrono project, in region eur3 — Europe. That
choice is deliberate and irreversible: the data stays in Europe. Google
acts here as a hosting provider on our behalf. Traffic is encrypted in transit
(HTTPS/TLS).
Let us be precise, because this matters: a published round is final. The database security rules forbid any modification and any deletion from the app. You therefore cannot delete a round you have published from within the game. This is a design decision — a duel cannot be rewritten after the fact — but it has to be stated plainly.
Rounds are kept without a predefined duration, so that they remain available to the players who will take them on. To have your published rounds and the anonymous identifier attached to them deleted, write to the contact address below: deletion is carried out manually, within thirty days. Local data, on the other hand, can be erased at any time from the app's Android settings, or by uninstalling it.
Since version 1.1.0, the hint shop offers a short video ad you can watch to earn a hint. It is the only place where an ad exists, and you are always the one who asks for it: never during a round, never forced, at most five a day. Ads are limited to the “everyone” content rating.
The ad service, Google AdMob, only starts when you open the hint shop. A player who never opens it never contacts an ad network. Once started, Google processes, to show and measure the ad and to prevent fraud: the Android advertising ID, your IP address (and therefore an approximate location), device information, your interactions with the ad and diagnostic data. Google then acts as an independent controller, under its own rules: how Google uses information from partner apps. We receive none of this data.
Your consent. In the European Economic Area, the United Kingdom and Switzerland, Google's consent form is shown before the first ad: you can accept, refuse or choose in detail. You can change your mind at any time in Settings → About → “Ad privacy”; if you withdraw consent, the ad already prepared is discarded. Everywhere, you can reset or delete your advertising ID in Android settings (Privacy → Ads).
The app contains no analytics or measurement tool (no Google Analytics, no Firebase Analytics, nor any equivalent) and no crash reporter. No data is sold, rented, or passed on to data brokers.
The app offers nothing for sale. Hints (reveal a letter, freeze the timer) are earned by playing, or by watching an optional video in the hint shop — never bought. No payment method is ever requested, and the app has access to no payment data whatsoever.

Under the GDPR, you may request access to the information concerning you, its rectification or its deletion, or object to its processing. The processing tied to online duels rests on performing the service you ask for: it starts only once you open that mode and publish a round. One address covers all such requests, given below. Since the identifier is anonymous, please state in your message the nickname you used and the approximate date of the rounds concerned — otherwise we cannot find them.
Where the law requires it, the optional advertising rests on your consent, which you can withdraw at any time (see “Optional advertising”). Requests about the data Google processes for advertising should be addressed to Google.
Anagramme chrono is not directed to children under 13: the audience declared on Google Play starts at 13. The content itself is rated for everyone — it is a word game with no violence, no bad language and no sensitive themes — but its pace, its vocabulary and its weekly competition are aimed at older players.
We do not knowingly collect data from a child under 13. If you are a parent or legal guardian and believe a child has sent us data, write to the contact address below: we will delete it, within thirty days. Please state the nickname used and the approximate date of the rounds concerned — as the identifier is anonymous, that is the only way to find them.
What follows holds for every player, whatever their age, and answers the questions a parent asks: no forced advertising (only an optional video, rated for everyone, in the hint shop), no trackers, no in-app purchases; no free exchange between players — no messaging, no chat, no comments, no public profile, no photos, no way to contact anyone; and the name your opponent sees is filtered, as described above. Finally, the campaign, the quick duel and the daily challenge run with no network and no account: as long as the “Online duel” screen is never opened, no account is created and nothing is transmitted; as long as the hint shop is never opened, no ad network is contacted.
Any change to this policy is published at this address, with a new update date. This version 1.5 of 23 September 2026 supersedes version 1.4 of 15 August 2026: it describes the optional advertising that came with version 1.1.0 of the app (Google AdMob, consent form, setting to change your choice) and the permissions it adds. Version 1.4 superseded version 1.3 of the same day: the audience declared on Google Play goes back to 13 and over, the “Children” section is rewritten accordingly, and the game is no longer presented as falling under the Google Play Families policy. Version 1.3 made clear that the name seen by your opponent may come from the Google Play Games account, not only from the nickname typed in the app. Version 1.2 superseded version 1.1 of 11 August 2026: it expanded the “Children” section after an audience of 9 and over was declared on Google Play. No data processing has changed — only the description became more precise. Version 1.1 itself superseded version 1.0 of 9 August 2026, which described an entirely offline app, a description that stopped being accurate when the online duel was added.
