Privacy policy

Effective from 9 November 2026

Who is responsible for your data

The data controller is Radosław Tarnas, running a business under the Dareia brand, ul. Nastrojowa 58/5, 91-496 Łódź, Poland, tax ID (NIP) 7251926767, REGON 101315010. Privacy contact: support@dareia.eu.

In short

Data stored only on your device

The game saves its state on your phone: unlocked levels and stars earned, acorns, the number of hints and when they refill, the number of boards you have won (so that ads between levels don't show up too often), your daily puzzle results and streak, your Endless mode record, and whether you have an active Mibboro Club or the “Remove ads” purchase. None of this is sent to us or anyone else, and it is not included in Android backups. Clearing the app's data or uninstalling the game deletes it permanently.

Ads (Google AdMob)

The game shows two kinds of ads:

• rewarded ads – in exchange for an in-game reward, such as extra moves after running out or a hint. They appear only after you tap such a button – you can play without them;
• full-screen ads between levels – every few boards you win, never while you are solving a board. They are not shown if you have Mibboro Club or the “Remove ads” purchase.

Ads are served by Google (Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland) through AdMob. To show an ad, measure how it performs (statistics and analytics) and prevent fraud, Google processes, among other things:

• your device's advertising ID (you can reset or delete it in Android settings) and the app set ID,
• your IP address, from which Google estimates your approximate location (e.g. country or city), and information about your device, system and app,
• interactions with the app and ads (e.g. app launches, ad views and clicks, whether an ad was watched to the end),
• diagnostic data about how the app and the ad library work (e.g. launch time, freezes).

In the European Economic Area, the UK and Switzerland, Google asks for your consent to personalised ads when you first launch the game. Without consent, you see non-personalised ads. You can change your choices at any time in the game's settings (“Ad settings”). The game asks Google only for ads suitable for everyone (rating G).

Data sent to Google is encrypted. Details: how Google uses information from apps that use its services, Google's privacy policy.

In-game purchases (Google Play)

In the game you can buy the Mibboro Club subscription, a one-off “Remove ads” purchase and hint packs. Payment is handled by Google Play – we never see your card details, email address or Google account. The game only receives a purchase confirmation from Google Play (product ID, time, order number and subscription status) so it can unlock what you bought – the Club and “Remove ads” also after reinstalling the game on the same Google account.

In the Google Play Console we see order details (order number, product, price, country, date and status), without your name or email address. We use them for accounting and to handle complaints and refunds. Purchases are subject to the Google Play Terms of Service, and payment data is processed by Google under its privacy policy.

Permissions

The game uses the internet and checks the connection state only to load ads and handle Google Play purchases; it also uses the advertising ID (AD_ID permission) for AdMob and the Google Play billing service (BILLING). Google's ad library may add technical permissions: READ_BASIC_PHONE_STATE (basic device information such as the mobile network type and system version – no phone number, calls or texts), WAKE_LOCK and FOREGROUND_SERVICE (so an ad and its handling can finish). The game does not use GPS location, the camera, the microphone, contacts or files on your device. You can also play offline – then there are no ads and no purchases.

Google Play

You download and update the game through Google Play. Data related to your Google account, downloads, updates and payments is processed by Google as a separate controller, as described in Google's privacy policy.

Apart from that, from Google Play we only receive aggregate statistics (e.g. the number of installs in a country) and – if diagnostic data sharing is turned on in Android settings – crash reports (device model and system version, the course of the error). From AdMob we only receive aggregate reports (e.g. ad impressions and revenue in a country). They do not contain your name, email address or account ID.

Purpose and legal basis

• Personalised ads: your consent (Art. 6(1)(a) GDPR), which you can withdraw at any time in the ad settings.
• Non-personalised ads that fund the free game, ad measurement and fraud prevention: legitimate interest (Art. 6(1)(f) GDPR).
• In-game purchases: performance of a contract (Art. 6(1)(b) GDPR); keeping order data for accounting: legal obligation (Art. 6(1)(c) GDPR).
• Crash reports, complaints and contacting us: legitimate interest (Art. 6(1)(f) GDPR).

Transfers outside the European Economic Area

Google may also process data outside the EEA. Such transfers rely on the mechanisms provided for in the GDPR and described in Google's privacy policy (e.g. the EU-U.S. Data Privacy Framework or standard contractual clauses).

How long

Data on your device – until you delete it. Ad and payment data on Google's side – according to Google's privacy policy. Order data visible to us – for the period required by tax and accounting law. Correspondence – as long as needed to deal with your matter.

Contacting us

If you write to us, we process your email address and the content of your message in order to reply (legitimate interest, Art. 6(1)(f) GDPR). We keep correspondence as long as needed to deal with your matter and then delete it. Our email runs on Google Workspace (Google Ireland Limited) – data may be transferred to the USA under the EU-U.S. Data Privacy Framework or standard contractual clauses.

This website

• mibboro.dareia.eu uses no cookies, no analytics and no scripts or fonts from third-party services – everything, including the gameplay video, comes from our own server.
• To display the site, the server receives your IP address, the date and time, the page address and browser information. These go into technical logs used only for security and maintenance (legitimate interest, Art. 6(1)(f) GDPR); they are kept briefly and overwritten automatically.
• The server is hosted in Germany by OVH (OVH GmbH), which processes this data on our behalf.
• If you choose the site language yourself (PL / EN), your browser remembers that choice on your device (localStorage). It is not sent to us. The “Try it yourself” mini-board runs only in your browser and saves nothing.
• The “Get it on Google Play” buttons are plain links – Google receives data only after you click them, under Google's terms.

Your rights

You have the right to access, rectify and erase your data, to restrict its processing, to data portability and to object, and – where processing is based on consent – to withdraw it (in the game's settings: “Ad settings”). Write to support@dareia.eu. You can also lodge a complaint with the Polish data protection authority (Prezes Urzędu Ochrony Danych Osobowych, ul. Stawki 2, 00-193 Warszawa) or with the supervisory authority in your country.

The game sends us no data, so we hold nothing that would identify you as a player – you delete the game's data yourself by clearing the app's data or uninstalling it. You manage ad data in Android settings (advertising ID) and in your Google account, and your purchase history in Google Play; for data processed by Google you can also contact Google directly.

Children

The game asks for no personal data and shows only ads suitable for everyone. Purchases require a Google account – parents can turn on purchase authentication in Google Play settings or use parental controls in Family Link. If you are a parent and believe your child has sent us personal data (e.g. by email), write to us and we will delete it.

Changes

We will announce changes to this policy in the game's update notes. The current version is always available at https://mibboro.dareia.eu/privacy.
