Quadrille Studio

Privacy Policy

This policy covers the quadrillestudio.com website and every game published by Quadrille Studio — today, Boxed In and Rubble. The first part applies to all of our games. Each game then has its own section saying exactly what it stores and where its privacy controls are.

Effective 10 August 2026 · Last updated 27 September 2026

The short version

  • None of our games asks for your real name, your email, or an account.
  • Your progress, your settings and your saved games live on your device. We have no servers, so none of it ever reaches us.
  • Games that show ads use Google AdMob, and the ad network sees what ad networks see — an advertising identifier, an IP address, and which ads you were shown.
  • Purchases go through Google Play or the App Store. We never see your payment details.
  • In the EEA, the UK and Switzerland you are asked before ads are personalised, and every game has a privacy entry in its menu where you can change that answer at any time.

Who we are

Quadrille Studio is a small independent game studio and the data controller for the processing described here. Every game we publish is covered by this one policy. You can reach us at hello@quadrillestudio.com for any question about this policy or about your data.

What every game has in common

Our games are built the same way. Everything a game saves — your progress, your settings, a game in progress — is written to the game's private storage on your device, or to your browser's storage for a browser version, and is never transmitted to us. There is no account to create, no sign-in, and no cloud save of our own. Each game's section below lists exactly what it stores, and notes where your device's own backup service may copy a save to a new phone under your own account.

Deleting a game deletes what it stored. Because we never had a copy, there is nothing we can recover, and nothing we need to erase.

Ads

Some of our games show ads through Google AdMob. Each game's section says which kinds: full-screen ads between rounds, or rewarded videos you choose to watch in exchange for something in the game. To select, deliver and measure ads, Google and its advertising partners may process:

  • your device's advertising identifier (the Android advertising ID, or the Advertising Identifier on iOS);
  • an approximate location, derived from your IP address;
  • device and app information such as model, operating system version, language and app version;
  • your interaction with ads shown in the game — which were requested, shown, viewed or tapped.

We do not receive any of this. We see only aggregate impression and revenue counts in the AdMob dashboard, which cannot be traced back to an individual. Google acts as an independent controller for this data. Its handling is described in the Google Privacy Policy and in how Google uses information from sites or apps that use its services; the companies involved are listed in Google's advertising partners list.

Each game that shows ads also sells a one-time purchase that turns them off. Once it is active, the game stops requesting ads, and nothing further is sent to the ad network.

Consent, if you are in the EEA, the UK, or Switzerland

The first time you open a game that shows ads you are asked whether you consent to personalised ads, through Google's User Messaging Platform. You can change that choice at any time — including withdrawing it entirely — from the privacy entry in the game's menu, named in each game's section below. That entry appears only where consent rules apply.

Declining does not restrict the game. You will simply see non-personalised ads, selected from context rather than from a profile.

Anywhere in the world, you can also limit advertising on the device itself: Android offers "Delete advertising ID" and "Opt out of Ads Personalisation" in Settings, and iOS lets you turn off "Allow Apps to Request to Track".

Purchases

Where a game sells something, it is a single one-time purchase handled entirely by Google Play, or by the App Store on Apple devices. We never see your payment details. The game keeps a small record on your device that the purchase is owned, and asks the store to confirm it again when you tap Restore purchases — which is how a purchase follows you to a new device. Each game's section says exactly what that record contains.

The store's handling of the transaction is covered by the Google Privacy Policy and, on Apple devices, by Apple's.

The website and browser versions

Some of our games can be played in the browser at quadrillestudio.com/game/play. Browser versions show no ads and sell nothing. Whatever the game would store on a device is kept in your browser's storage for this site instead, and never sent to us; clearing the site's data in your browser deletes it.

The website, including the play pages, uses Cloudflare Web Analytics so we can see whether anyone is visiting. It is cookieless and does not fingerprint you: it records page views with the country, browser type and referring site, in aggregate only. It cannot identify you, and it does not see anything that happens inside a game — which modes you play, how long, or how you do. Cloudflare's handling of that data is described in the Cloudflare Privacy Policy.

What we do not do

  • No analytics SDK in any game. None. We do not know how long you play or which screens you open, on any platform.
  • No crash-reporting SDK either.
  • No accounts, no sign-in, no email collection, no newsletters.
  • No servers of our own. A game talks to Google's advertising and billing services, and to nothing else.
  • No selling or sharing of personal data with anyone beyond the ad network described above, and we never have.
  • The website sets no cookies. Its only measurement is the cookieless, aggregate page-view count described above.

Boxed In

Boxed In is a dots-and-boxes game for Android, iOS and the browser. Everything above applies; these are its specifics.

What stays on your device

  • The name you play under — free text, "Player 1" until you change it. Put nothing there you would not want on your own screen.
  • Your game in progress — the board, whose turn it is, and the score, so a game resumes exactly where you left it.
  • Your record — games played, won, lost and tied, per mode.
  • Your settings — board size, opponent difficulty, theme, and whether sound and haptics are on.

Uninstalling the app deletes all of it. There is no cloud save and no backup.

Ads and Pro

The app shows full-screen ads between games and optional rewarded ads you choose to watch. Buying Pro, a one-time purchase, turns ads off. The app keeps a single true/false value on your device recording whether Pro is owned, and Restore Purchases asks the store to confirm it again.

Privacy controls

Where consent rules apply, Main menu → Privacy options reopens the consent form so you can change or withdraw your answer.

The browser version

You can play Boxed In at quadrillestudio.com/boxed-in/play. That version shows no ads and sells nothing, and keeps the same data listed above in your browser's storage for this site.

Rubble

Rubble is a gravity puzzle, in development, with Android first. This section describes the game as it is built today; if anything changes before release, this page changes first. Everything above applies; these are its specifics.

What stays on your device

  • Your progress — your best score on each level and on each day's daily puzzle, which levels you chose to skip, and the attempt you are in the middle of, so you can continue where you left off.
  • Hint bookkeeping — whether today's free hint has been used, and any hint credits you have earned.
  • Your settings — sound, music, reduced motion, haptics, and how far through the tutorial you are.

There is no name field. Nothing in the save identifies you as a person.

On Android, the progress file is included in your device's own backup to your Google account and in device-to-device transfer, so your progress can follow you to a new phone. That is a service Google runs under your account; we receive nothing from it. The purchase record and hint credits are deliberately left out of the backup — the store re-confirms the purchase instead.

Ads and the one-time purchase

Rubble offers a rewarded video in exchange for a hint, which you can always decline, and shows a full-screen ad after you finish a level. The one-time purchase removes ads and makes hints unlimited. When no ad can be shown — offline, no consent, no ad available — the game gives you a hint anyway. Playing offline is never blocked.

The purchase record kept on your device holds the store's product id, whether it is owned according to the store's last answer, when that was confirmed, and the store's own transaction reference. It holds no receipt, price or payment method. Restore purchases in Settings asks the store again, and Reset progress never touches it.

Privacy controls

Where consent rules apply, Settings → Privacy choices reopens the consent form so you can change or withdraw your answer. Settings → Reset progress deletes the save described above and nothing else; your purchase stays.

Diagnostics you control

While it runs, Rubble keeps a short list of what happened in this session — a level started or finished, a hint given, an ad shown or not, a purchase result — at most 200 entries, in memory only. It holds no identifiers, no free text and nothing from your save. It is never written to disk in a release build, never sent anywhere on its own, and is gone when the app closes. Settings → Support → Share diagnostics shows you that exact text; you can then copy it, or open it in your own mail app addressed to us, and you decide whether to send it. Nothing is sent unless you send it.

The Support entry in Settings likewise only opens your mail app, with a message containing the app version and platform and nothing else.

Children

Our games are general-audience games. They are not directed to children, and we do not knowingly collect personal information from children. If you believe a child has provided us with personal information, write to hello@quadrillestudio.com and we will act on it.

Your rights

Because we hold no data about you ourselves, there is nothing on our side to export, correct or erase — deleting a game removes everything it stored. Rights of access, rectification, erasure, restriction, objection and portability under the GDPR and UK GDPR, and the rights of access, deletion and opt-out under California law, apply to the data Google processes for advertising. Those requests are best made to Google directly through the links above, and we will help however we can if you write to us.

Where consent is the basis for processing — personalised advertising in the EEA, UK and Switzerland — you may withdraw it at any time through the game's privacy entry, without affecting anything that happened before. You also have the right to complain to your local data protection authority.

Retention

We retain nothing, because we collect nothing. Data on your device lasts until you delete the game, or, where your device backs a save up under your own account, for as long as you keep that backup. Data processed by Google for advertising and billing is retained under Google's own schedules, described in its privacy policy.

Changes

When a new game is published, it gets its own section here before it is available. If a game changes in a way that affects your privacy, this page is updated before that change reaches you, and the date at the top changes with it. Material changes are also noted in that game's release notes.
