Skwizzo® Bubble Merge privacy policy

Last updated: 2 November 2026

Back to the project

Skwizzo® Bubble Merge is developed and published by Quaradur Industries (“we”, “us”). This policy covers the game on Android and on iPhone and iPad. Questions about this policy: support@quaradurindustries.com.

1. Data that stays on your device

The game stores on your device:

  • game progress: completed levels, coins, power-ups, lives and what you have purchased (coins, power-ups and bundles);
  • your preferences: music, sound effects, vibration, language, and whether we have already asked for permission to send notifications;
  • whether you have accepted the terms of service, whether you have already seen the advertising consent form, and your answer;
  • whether your account is linked, or whether you chose not to link it (section 2);
  • a device code: a cryptographic fingerprint of the device identifier, used for the signal in section 2, from which the identifier cannot be recovered;
  • a random identifier generated by the game on first launch, used only to tell one save file from another. It contains nothing about you and is not derived from your device or your account: it is a random number that is born with the save file and dies with it.

This data never leaves the device unless your account is linked (section 2). Uninstalling the game deletes it.

On Android, automatic backup is turned off for this game. That is our choice and it is worth stating, because Android defaults to the opposite: without it, your save file would be copied to your Google Drive on every phone backup, without asking you. With backup off, the only copy that leaves the device is the one in section 2, and only if your account is linked.

On iPhone and iPad, the game does not exclude its files from device backups. If you have turned on iCloud Backup or backups to a computer, iOS includes them along with the data of your other apps: that backup is yours, managed by Apple and under your control, and we cannot access it.

2. Cloud saves

Linking an account is optional: Skwizzo Bubble Merge is complete and fully playable without one. This is how linking happens:

  • on first launch the game offers to link it, with the sign-in panel of Google Play Games (Android) or Game Center (iPhone and iPad). If you are already signed in to that service on the device, you will usually only see its short welcome message: linking happens on its own, with no further questions, and from then on the game links again on its own at every launch;
  • if you close the panel without signing in, your progress stays only on the device and the game does not offer it again at later launches;
  • if your account is not linked, you can link it whenever you want from the game's Settings, with “Link an account”. The game also offers it before a purchase, and you can buy anyway without linking.

With your account linked, two things go to the cloud:

  • a copy of your save file, that is, the information in section 1 that belongs to the game in progress, including the random identifier;
  • a small signal used to keep the game open on one device at a time, so that two devices do not overwrite each other's progress. The signal contains a code for the device that is playing: not the device identifier itself, but a cryptographic fingerprint of it, from which the identifier cannot be recovered.

Stopping cloud saves. There is currently no command inside the game to unlink your account. You can do it from the service:

  • on Android, in your Play Games profile (Google Play Store app → profile icon → Settings → General → Play Games Profile → Sign in account) you can sign out of all games; the steps are in Google's help (https://support.google.com/googleplay/answer/3129346?hl=en). Keep in mind that this applies to every game that uses Play Games, not just this one;
  • on iPhone and iPad the game can only write to the iCloud database while an iCloud account is active on the device: if you sign out of iCloud, it stops.

Copies already saved do not disappear on their own: to delete them, see section 10.

On Android: Google Play Games Services.

  • It recognises you through the Google account already on your phone. We do not create any new account and we do not ask you to register.
  • It stores the copy and the signal in the “Saved Games” space Google reserves for this app in your account: a hidden folder in your Google Drive, reserved for this game.

Where this data goes, and who can read it, on Android. Google stores it, in your account. We have no access to that space and cannot read the contents of your games. There is no server of ours in between, and the game does not read or store your name, your email address or your Play Games profile.

Google's handling of this data is governed by its own terms:

On iPhone and iPad: Game Center and iCloud.

  • Game Center recognises you through the account already on your device. We do not create any new account, and the game does not store your Game Center nickname or identifier.
  • iCloud (Apple's CloudKit service) stores the copy and the signal. An active iCloud account on the device is required. The copy follows the iCloud account, not the Game Center one: if on the same device the two belong to different people, the progress follows iCloud.

Where this data goes, and who can read it, on iPhone and iPad. This works differently from Android, and it deserves to be stated precisely. The copy is not in your personal iCloud storage: it is in the public database of Skwizzo Bubble Merge's iCloud container, which Apple hosts on its servers on our behalf and which uses the storage allocated to us as developers, not yours. We chose it so that saving keeps working even when your iCloud storage is full.

  • “Public” is the technical name Apple gives to this kind of database and does not mean other players can read it: the access rules allow each account to read and change only its own records.
  • Your records are labelled with a code that Apple assigns to your iCloud account for this game only. It does not contain your name, your email address or your Apple Account, and we have no way to trace that code back to you.
  • As developers, however, we can see those records in the management tool Apple provides to us (CloudKit Console). That is why, unlike on Android, we treat these copies as data we hold: we use them only for cloud saves, we do not combine them with other data, and we do not share them with anyone.

Apple's handling of this data is governed by its own terms:

3. The connectivity check

No internet connection is needed to play Skwizzo Bubble Merge, whether or not you have linked an account. If the connection is missing, you play on the device and, if your account is linked, the cloud copy is updated as soon as the network returns.

To notice this, the game makes a request to a Google address (https://www.google.com/generate_204) and looks only at whether it answers. That request:

  • contains nothing about you: no identifier, no game data, no device data beyond what any web request carries (IP address and the type of software making the request);
  • receives nothing back: the address is the one operating systems have used for years for the same question, and it returns an empty page;
  • is not logged by us, because it does not pass through any server of ours: we have none.

Google, like any recipient of a web request, sees the IP address it comes from. The check only serves to find out whether the network is there: without a connection the game works all the same, on the device.

4. Purchases

The game offers optional purchases (coins, power-ups and bundles). Purchases are handled entirely by the store: Google Play on Android, Apple's App Store on iPhone and iPad. The transaction, the payment and your payment details go through them, not through us. We never see or store your card number, address or billing information.

At the time of purchase the game sends the store a code that contains no personal data — a cryptographic hash of the random identifier described in section 1 — which Google and Apple use for fraud prevention. On its own, that code does not reveal who you are.

What the game stores is only what you bought, so that it can be delivered to you: it is in the save file described in section 1 and, if your account is linked, also in its cloud copy (section 2).

On iPhone and iPad, the account you buy with (Media & Purchases) may differ from your iCloud account and from your Game Center account: purchases stay tied to the account they were made with.

For refunds and payment issues, the store is the point of contact:

5. Notifications

The game may send you notifications: when your lives are full again, when free coins can be claimed again, or to remind you of the level you have reached. These are local notifications: your device schedules them, they do not come from any server, and they require no one to know where you are or what you do.

On iPhone, iPad and recent versions of Android, the system asks for your permission first. You can turn them off at any time from your system settings.

6. Advertising

The game shows advertising only in the form of rewarded ads, videos that you choose to watch. There are no banners or full-screen ads between rounds. Ads are served through Google AdMob, which also acts as the mediation layer: on every request it puts several ad networks in competition and gives the slot to whichever bids highest. The networks that can answer are Google AdMob itself, Unity Ads and Liftoff (formerly Vungle). Mediation may also pass the request on to other advertising partners: the current list of who can receive your data is the one shown inside Google's consent form, where you can review it partner by partner. All of them receive only the technical information described below.

Rewarded ads are always your choice. Nothing in the game is taken away if you do not watch one: they buy you extras — coins, a life, a power-up, or a second chance when you lose a level — never access to what you already have.

Before showing you personalised advertising we ask for your permission, using a form provided by Google (User Messaging Platform), in the countries where it is required: for example in the European Economic Area and the United Kingdom. Your answer is stored on your device and you can change it at any time (section 10).

  • If you consent, the ad networks may use your device's advertising identifier to show you more relevant ads.
  • If you do not consent, you will still see advertising, but not personalised.

On iPhone and iPad there is also Apple's prompt (App Tracking Transparency), which asks whether the game may track your activity across other companies' apps and websites. Where Google's form is required, Apple's prompt comes afterwards, and only if you have consented; elsewhere it is the only question. If Google's form fails to load, Apple's prompt appears anyway, even where the form would be required; your answer to Apple does not, on its own, make ads personalised. If you decline Apple's prompt, your device's advertising identifier is not used and ads are not personalised, whatever you answered to Google.

In every case the networks receive some technical information needed to serve and measure an ad: for example the device type, the IP address (from which the country or approximate area can be estimated), other identifiers the system assigns to the app, the ads shown and your interactions with them. They also receive some information about how the app and their own software are performing — for example how long it takes to start up, or whether an ad failed to load — which they use to measure performance and prevent fraud. Data collected for advertising is processed by them, as independent controllers, under their own policies:

We never receive, store or cross-reference that data, and we have no way to trace an ad back to a person.

To have them ready if you choose to watch them, the game requests rewarded ads from the networks in advance, which therefore receive the technical information described above.

7. Usage statistics and error reporting (Google Firebase)

To improve the game we use two Google Firebase services: Firebase Analytics for usage statistics and Firebase Crashlytics for crash reports. We also use Firebase Remote Config, which lets us deliver certain settings without updating the app: it receives data and sends none about you.

What is recorded:

  • What happens in the game: installation and first launch; sessions and their length; screens opened; levels started and finished (with mode, level number, outcome and time); power-ups used; coins earned and spent; in-game purchases (which product, not your payment details); ads shown, clicked or watched;
  • Device: model, operating system, language, game version, and approximate country or region derived by Google from the IP address, which is not stored;
  • Identifiers: a random installation identifier, which changes if you reinstall the game. If you have consented to personalised advertising, also the device's advertising identifier;
  • Error reports: the point in the code where the app closed, the state of the device (memory, free space) and the random identifier.

We do not record your name, email, phone number, precise location, contacts or the contents of saved games.

To understand who plays the game we use Google Signals and Google's demographic and interest reports (age range, gender, interests). They work only for people who have consented in the form (otherwise Firebase stays off, as described above) and who have personalised ads enabled in their Google account; Google shows us these figures only in aggregated form and above a minimum number of users, never about a single person, and we do not use them to identify anyone or to build profiles of our own. You can switch them off from your Google account (myadcenter.google.com) or by declining the consent form.

When: in the European Economic Area and the United Kingdom, Firebase stays off until you accept in the form shown at first launch. If you decline, nothing is sent. In the rest of the world, where consent is not required, it is switched on at launch.

Who sees it: the data is stored by Google, which processes it on our behalf as a processor, including outside the EU, under standard contractual clauses. We see it only in aggregated form and we do not pass it on to anyone.

For how long: statistics for at most 14 months, error reports for about 90 days.

8. Updates and reviews

On Android the game uses two Google Play services. The first checks whether a newer version is available on Google Play: if there is one, the game stops and asks you to update it before continuing. The second asks you — rarely, and never insistently — to leave a review. On iPhone and iPad the review request is Apple's system prompt, and updates come through the App Store. These are Google Play and Apple features, and they send us no data about you.

9. What we do NOT do

For clarity, here is what this game does not do:

  • we have no server of our own: besides the iCloud database in section 2, used only by people who play on iPhone or iPad with a linked account, the only data that concerns us are the statistics described in section 7, stored by Google on our behalf and visible to us only in aggregated form; we do not use them to recognise you or to build a profile of you;
  • we never ask for your email, phone number, name, date of birth or location;
  • we do not access your contacts, photos, microphone, camera or location;
  • we do not sell or share with anyone any data that concerns us: for advertising and for statistics, the exceptions below apply.

The exceptions are advertising (section 6) and statistics (section 7). For advertising, the data is collected by the ad networks, on their own behalf and under their own policies: we do not see it, we do not store it, and we receive no player profiles from them. For statistics, section 7 applies.

10. Data retention and deletion

On your device. Data stays as long as the game is installed, and the only way to remove it is to remove the game: uninstall it or, on Android, clear the app's data from your settings. There is no command inside the game that deletes it.

In your Google storage (Android). The cloud copy lives in your account, not with us, so you control it. To delete it:

  • in the Google Play Store app: profile icon → Settings → General → Play Games profile → Privacy & settings → Delete Play Games profile and data, then, under “Delete individual game data”, Skwizzo Bubble Merge; on a computer, the same option is at https://play.google.com/games/profile; or
  • in Google Drive on the web: Settings → Manage apps → Skwizzo Bubble Merge → Options → Delete hidden app data.

We cannot delete that data on your behalf, because we cannot access it. If you keep playing with your account linked after deleting it, the game saves a new copy: to avoid that, see section 2.

In the game's iCloud database (iPhone and iPad). We keep these copies for as long as the game's cloud save exists and you have not asked us to delete them. Uninstalling the game, signing out of iCloud or managing your iCloud storage from Settings does not delete them, because they are not in your iCloud storage, and they cannot be deleted from inside the game. To have them deleted, write to support@quaradurindustries.com. Because the records contain nothing that identifies you, to find yours we will ask you for some details about your game: for example the level you reached, your coins, and the approximate date and time you last played with the account linked. If those details are not enough to recognise your records with certainty, we will tell you, rather than risk deleting someone else's data. Here too, if you keep playing with your iCloud account active, the game saves a new copy (section 2).

Statistics (section 7). They delete themselves within the periods stated. If you uninstall the game, the random identifier is lost and the data can no longer be linked to your phone. For earlier deletion, write to us: since we do not know who you are, we will ask for a few details to find them, such as the day you played and your phone model.

To withdraw consent to advertising and statistics:

  • where Google's form is required: the game's Settings → Ad preferences, which reopens the same form you saw the first time, with your earlier answer already selected. Where the form is not required, that button does not appear;
  • on iPhone and iPad: Settings → Privacy & Security → Tracking, where you can revoke Skwizzo Bubble Merge's permission at any time;
  • outside the European Economic Area and the United Kingdom you can ask us by email, at support@quaradurindustries.com, not to use your statistics;
  • on Android you can also reset or delete your device's advertising ID from the system settings.

For questions or help with any of these steps, write to support@quaradurindustries.com: we reply within 30 days.

11. Children

Skwizzo Bubble Merge is not directed at children under 13 and we do not knowingly collect data relating to them. The game asks no one for a name, an email address or any other personal information, whatever their age.

If you are a parent, the one thing worth keeping an eye on is purchases: they go through Google Play or the App Store and can be protected by requiring authentication for every transaction, from the store's settings (on iPhone and iPad also with Family Sharing and Screen Time). If you believe your child has provided us with data — for example a save copy in the iCloud database described in section 2 — write to support@quaradurindustries.com and we will look into it and, if we can recognise it as explained in section 10, delete it.

12. Your rights

If you are in the European Union or the United Kingdom, the GDPR gives you the right to access your data, correct it, delete it, restrict its processing, object to it, and receive it in a portable form.

The data on your device and in your Google account is under your direct control (section 10). For the copies in the game's iCloud database and for the statistics in section 7 you can ask us for access, a copy or deletion by writing to support@quaradurindustries.com: what section 10 says about how we recognise them applies.

You also have the right to lodge a complaint with a supervisory authority: in Italy this is the Garante per la protezione dei dati personali (https://www.garanteprivacy.it), otherwise the authority of the country where you live.

The legal basis for processing is your consent for personalised advertising and, in the European Economic Area and the United Kingdom, for statistics and error reporting; elsewhere, for statistics and errors, our legitimate interest in improving the game. For everything else it is performance of a contract (running the game, keeping your cloud copy while your account is linked, and delivering what you purchase).

Outside the European Union and the United Kingdom. Wherever you live you can ask us to access, correct or delete the data we hold about you and to withdraw your consent, by writing to support@quaradurindustries.com: we reply within 30 days. In Brazil, the LGPD (art. 18) gives you the rights of confirmation, access, correction, anonymisation or deletion, portability, information on who receives your data and revocation of consent, and you may complain to the ANPD (https://www.gov.br/anpd). In the United States, including California and the other states with privacy laws, you have rights of access and deletion, and we do not sell your personal data ourselves; advertising is served by third parties acting as independent controllers (section 6), and you can limit personalisation by declining in Google's form and, on iPhone, by declining tracking in iOS Settings → Privacy & Security → Tracking. In Japan the Act on the Protection of Personal Information (APPI) applies, and you can use the same address. On Android you can also delete or reset your advertising identifier from your device's Settings (Google → Ads).

13. Changes to this policy

If anything changes — for example if we add a new service — we will update this page and the date at the top before the change takes effect in the game.
