Skwizzo® Block Jam privacy policy

Last updated: 2 September 2026

Back to the project

Skwizzo® Block Jam is developed and published by Quaradur Industries (“we”, “us”). 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, gems, items and power-ups owned, lives;
  • your preferences: chosen language, volume levels, notifications on or off;
  • whether you have already seen the advertising consent form, and your answer;
  • a random identifier generated by the game on first launch, used only to tell one save file from another. It is not linked to you, 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 you link an account (section 2). Uninstalling the game deletes it.

Android's 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 you ask for it.

2. Cloud saves, if you choose them

Linking an account is optional. Skwizzo Block Jam is complete and fully playable without one. You can link it whenever you want, and unlink it whenever you want, from the game's Settings.

If you link it, the game uses Google Play Games Services to:

  • recognise you through the Google account already present on your device. We do not create any new account and we do not ask you to register;
  • store a copy of your progress in the “Saved Games” space Google reserves for you for this app;
  • check that the game is open on one device at a time, so that two phones do not overwrite each other's progress.

Where this data goes, and who can read it. The save file is stored by Google, in the space tied to 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.

When you link the account, the game receives from Google a player identifier and the public name of your Play Games profile. They are used to know whose save file it is, and they stay on the device.

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

3. The connectivity check

Skwizzo Block Jam requires an internet connection, whether or not you have linked an account. If the connection is missing, the game tells you so and does not continue until it comes back.

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 system browser type);
  • 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. If that feels like too much, the only alternative is not to use the game: the connection is a requirement, not an option.

4. Purchases

The game offers optional purchases (coins, items, ad removal). Purchases are handled entirely by Google Play: the transaction, the payment and your payment details go through Google, not through us. We never see or store your card number, address or billing information.

At the time of purchase the game sends Google a code that cannot be traced back to you — a cryptographic hash of the random identifier described in section 1 — which Google uses for fraud prevention. It contains no personal information and allows no one to identify you.

What the game stores locally is only what you bought, so that it can be delivered to you.

For refunds and payment issues, Google Play is the point of contact: https://support.google.com/googleplay/answer/2479637

5. Notifications

The game may send you notifications (for example when your lives have refilled, or to remind you of a level left unfinished). These are local notifications: your phone schedules them, they do not come from any server, and they require no one to know where you are or what you do.

You can turn them off from the game's settings or from your system settings, at any time.

6. Advertising

The game shows advertising: banners, interstitial ads (including video) between rounds, and ads you choose to watch in exchange for a reward. 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 AppLovin. 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, an extra life, a second chance when a level's time runs out — never access to what you have already earned.

Before showing you personalised advertising we ask for your permission, using a form provided by Google (User Messaging Platform). Your answer is stored on your device and you can change it at any time from the game's Settings.

  • 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.

In both cases the networks receive some technical information needed to serve an ad (for example device type and country). 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.

If you purchase the ad removal from the in-game shop, ads stop being shown and the related collection stops with them.

7. Updates and reviews

The game uses two Google Play services: one to offer you updates when a new version is released, and one to ask you — rarely, and never insistently — to leave a review. These are Google Play features and they send us no data about you.

8. What we do NOT do

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

  • we have no server of our own and store no data about you;
  • we collect no usage statistics and use no analytics or crash-reporting tools;
  • 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 any data of ours with anyone, because we hold none: for advertising, the exception in section 6 below applies.

The one exception is the advertising described in section 6: there 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.

9. 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 clear the app's data from your Android settings. There is no command inside the game that deletes it.

In your Google storage space. The cloud save lives in your account, not with us, so you control it. To delete it:

  • open the Play Games app → your profile → Settings → Delete Play Games account and data, selecting this game's data; or
  • from https://myaccount.google.com, in the section for connected apps.

We cannot delete that data on your behalf, because we cannot access it.

To withdraw advertising consent: the game's Settings → Privacy policy. Where the form is required — that is, in the European Economic Area and the United Kingdom — that button reopens the same form you saw the first time, with your earlier answer already selected. Elsewhere the same button opens this page.

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

10. Children

Skwizzo Block Jam carries an IARC 3+ rating: the content is suitable for everyone, from age 3 up. That concerns what you see and do in the game, not data: the game asks no one for a name, an email address or any other personal information, whatever their age, and we do not knowingly collect data relating to a child.

If you are a parent, the one thing worth keeping an eye on is purchases: they go through Google Play and can be protected by requiring authentication for every transaction, from the store's settings. If you believe your child has provided us with data, write to support@quaradurindustries.com and we will look into it.

11. 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.

In our case these rights are easy to exercise, because we hold nothing: the data is on your device and in your Google account, under your direct control (section 9). You may nonetheless write to support@quaradurindustries.com for any request.

The legal basis for processing is your consent for personalised advertising, and performance of a contract (running the game and delivering what you purchase) for everything else.

12. 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.
