It is very important for us to protect your personal information!
So we want to give you information about what data we collect, why we collect it and what we do with it, whether you use:
Personal data (usually referred to just as “data” below) will only be processed by us to the extent necessary and for the purpose of providing a functional and user-friendly website and app, including its contents, and the services offered there.
Per Art. 4 No. 1 of Regulation (EU) 2016/679, i.e. the General Data Protection Regulation (hereinafter referred to as the “GDPR”), “processing” refers to any operation or set of operations such as collection, recording, organization, structuring, storage, adaptation, alteration, retrieval, consultation, use, disclosure by transmission, dissemination, or otherwise making available, alignment, or combination, restriction, erasure, or destruction performed on personal data, whether by automated means or not.
The following privacy policy is intended to inform you in particular about the type, scope, purpose, duration, and legal basis for the processing of such data either under our own control or in conjunction with others. We also inform you below about the third-party components we use to optimize our website and improve the user experience which may result in said third parties also processing data they collect and control.
Our privacy policy is structured as follows:
The party responsible for this website and the apps (the “controller”) for purposes of data protection law is:
BitMultiplikator
Ingo Grebe
Ικτίνου 39 (Iktinou 39)
12243 Αιγάλεω (Egaleo)
Greece
Phone: +49 176 43675945
Email: info@biqui.org
With regard to the data processing to be described in more detail below, users and data subjects have the right
In addition, the controller is obliged to inform all recipients to whom it discloses data of any such corrections, deletions, or restrictions placed on processing the same per Art. 16, 17 Para. 1, 18 GDPR. However, this obligation does not apply if such notification is impossible or involves a disproportionate effort. Nevertheless, users have a right to information about these recipients.
Likewise, under Art. 21 GDPR, users and data subjects have the right to object to the controller’s future processing of their data pursuant to Art. 6 Para. 1 lit. f) GDPR. In particular, an objection to data processing for the purpose of direct advertising is permissible.
Your data processed when using our website and/or our BiQui app (Android, iOS) will be deleted or blocked as soon as the purpose for its storage ceases to apply, provided the deletion of the same is not in breach of any statutory storage obligations or unless otherwise stipulated below.
For technical reasons, especially to ensure a secure and stable website and app, the following data sent by your internet browser or by the BiQui app to us or to our server provider will be collected. These server log files record the type and version of your browser, operating system, the website from which you came (referrer URL), the webpages on our site you visit, the date and time of your visit, as well as the IP address from which you visited our site or used our app.
The data thus collected will be temporarily stored.
The basis for this storage is Art. 6 Para. 1 lit. f) GDPR. Our legitimate interest lies in the improvement, stability, functionality, and security of our website and our app.
The data will be deleted within no more than 14 days, unless continued storage is required for evidentiary purposes. In which case, all or part of the data will be excluded from deletion until the investigation of the relevant incident is finally resolved.
We use cookies on our website. Cookies are small text files or other storage technologies stored on your computer by your browser. These cookies process certain specific information about you, such as your browser, location data, or IP address.
This processing makes our website and app more user-friendly, efficient, and secure, allowing us, for example, to display our website in different languages.
The legal basis for such processing is Art. 6 Para. 1 lit. b) GDPR, insofar as these cookies are used to collect data to initiate or process contractual relationships.
If the processing does not serve to initiate or process a contract, our legitimate interest lies in improving the functionality of our website and app. The legal basis is then Art. 6 Para. 1 lit. f) GDPR.
When you close your browser, these session cookies are deleted.
If necessary, our website may also use cookies from partner companies with whom we cooperate for the purpose of analysis or improving the features of our website.
You can refuse the use of cookies by changing the settings on your browser. Likewise, you can use the browser to delete cookies that have already been stored. However, the steps and measures required vary, depending on the browser you use. If you have any questions, please use the help function or consult the documentation for your browser or contact its maker for support.
If you prevent or restrict the installation of cookies, not all of the functions on our site may be fully usable.
This app is intended for teens aged 13 and older and adults. It is not intended for children under 13.
We do not knowingly collect personal information from children under 13. If we become aware that personal information from a child under 13 has been inadvertently collected, it will be promptly deleted.
Parents or legal guardians who believe their child has provided us with personal information can contact us at any time; we will then immediately remove the relevant data.
The Stand Firm Tour app does not collect or use any personal data.
If you create a user account or obtain guest access via our website or app, we will use the data you entered during registration exclusively for services leading up to your potential placement of an order or entering some other contractual relationship with us, to fulfill such orders or contracts, and to provide customer support or gaming services. We also store your IP address and the date and time of your registration. This data will not be transferred to third parties.
Apart from the data required to play the BiQui game, we also collect and store all personal information you added to your account (e.g. username, password [encrypted], profile picture, email address, language). Your country will also be stored on the server.
You do not need to provide your email address. If known it will only be used to reset your password and to send you a new one if needed or to contact you by the BiQui team. Your email address will not be used for advertisement.
Some information—e.g., your username and profile picture, as well as your chosen language, country, and level (which determines the number of cards and categories you can play)—can be seen by other players as soon as they add you to their list of friends or start a game with you, or when the Phone-a-Friend lifeline is used.
All games and chat messages from a given game are stored for about 30 days on our servers and deleted after this time period. All communication between you and the BiQui team is currently saved indefinitely (e.g. in case of submitting additional questions).
During the registration process, your consent will be obtained for this processing of your data, with reference made to this privacy policy. We use the data exclusively to provide your user account or guest access and the gaming services.
If you give your consent to this processing, Art. 6 Para. 1 lit. a) GDPR is the legal basis for this processing.
If the opening of the user account or guest access is also intended to lead to the initiation of a contractual relationship with us or to fulfill an existing contract with us, the legal basis for this processing is also Art. 6 Para. 1 lit. b) GDPR.
You may revoke your prior consent to the processing of your personal data at any time under Art. 7 Para. 3 GDPR with future effect. All you have to do is inform us that you are revoking your consent.
The data previously collected will then be deleted as soon as processing is no longer necessary. However, we must observe any retention periods required under tax and commercial law.
If you send the BiQui referral link to others, the message contains your username; the username is not included in the link itself. The message is sent by you and can be edited before sending.
If the recipient enters the referrer’s username when creating an account, we inform the referrer in-app about the successful registration and automatically add both players to each other’s friends list (the friendship can be deleted at any time). Both players also receive a certain number of lifelines.
Purposes: Rewarding with lifelines and connecting the parties (friends list).
Legal basis: Art. 6(1)(f) GDPR (legitimate interest in a fair referral programme and a social function). Our interest prevails because providing the information is voluntary, is limited to minimised data (username), and the connection can be removed at any time by deleting it from the friends list.
Voluntariness: Providing the information is voluntary; without it, participation in the referral programme and the lifeline reward is not possible.
Storage period: We store the referral information for up to 12 months for potential inquiries; the friendship remains until it is deleted by the parties.
Disclosure: There is no disclosure to third parties.
If you contact us via email or the contact form, the data you provide will be used for the purpose of processing your request. We must have this data in order to process and answer your inquiry; otherwise we will not be able to answer it in full or at all.
Legal basis: Art. 6 Para. 1 lit. b) GDPR.
Storage period: Your data will be deleted after 12 months once we have fully answered your inquiry and there is no further legal obligation to store your data, such as if an order or contract resulted therefrom.
We offer the option to make donations via the payment service PayPal (PayPal (Europe) S.à.r.l. & Cie. S.C.A., 22–24 Boulevard Royal, L-2449 Luxembourg). If you click the PayPal donation link, you will be redirected to PayPal’s pages. To process the donation, PayPal—as an independent controller—processes the payment data you enter.
In this context, we receive from PayPal, among other things, transaction-related information (e.g. transaction ID, amount, currency, time, donation note, status) as well as—if provided by you and/or transmitted by PayPal—contact details (e.g. name, email address). We do not receive complete payment details (e.g. card or account numbers).
Purpose/legal bases: Processing your donation (Art. 6(1)(b) GDPR); in addition, our legitimate interest in secure and efficient payment processing and in preventing misuse (Art. 6(1)(f) GDPR).
Recipients/third-country transfer: PayPal, as an independent controller, may process data outside the EU/EEA; according to PayPal, appropriate safeguards (e.g. Standard Contractual Clauses) are used. For details on the purpose, scope and further processing, please see PayPal’s privacy notices: https://www.paypal.com/de/webapps/mpp/ua/privacy-full.
Storage period: We store the donation transaction data that accrue with us only as long as necessary to process the donation and to handle enquiries or to assert/defend claims. We delete this data after 10 years.
Service provider: Google Ireland Limited (Gordon House, Barrow Street, Dublin 4, Ireland) and Google LLC (1600 Amphitheatre Parkway, Mountain View, CA 94043, USA) as processors.
We use the Firebase services Crashlytics and Cloud Messaging in the BiQui app to ensure stability and security and to provide targeted information (e.g. for game invitations or when you can continue playing, or for promotions).
When using Firebase services, personal data may be transferred to Google LLC in the USA. If Google LLC is certified under the EU-U.S. Data Privacy Framework (DPF), the transfer takes place on the basis of this adequacy decision (Art. 45 GDPR). If and to the extent no DPF certification applies, we base the transfer on the EU Commission’s Standard Contractual Clauses (Art. 46 GDPR) and, where appropriate, supplementary measures. Nevertheless, there may be a higher risk of government access in the USA compared to the EU.

The data processing terms can be found at
Purpose: Detecting, analysing and fixing technical errors/crashes to ensure the app’s stability and security.
Categories of data processed: Crash traces (e.g. crash stack traces, Breakpad/NDK minidumps), Crashlytics installation UUID, technical device characteristics (operating system, device), time and app version at the event.
Legal basis: Art. 6(1)(f) GDPR (legitimate interest: stable and secure provision of our app). You may object on grounds relating to your particular situation (Art. 21 GDPR). You can also disable the sending of error and crash reports in the app settings.
Storage period: Personal data is stored for 90 days.
Opt-out option: You can disable the sending of error and crash reports for the future in the BiQui app under Settings.
Purpose: Sending in-app and push notifications, including game invitations, information when you can continue playing, and information about promotions. Push notifications are not used for advertising outside the BiQui app.
Categories of data processed: Firebase Installation ID (pseudonymised identifier of your device/app instance), where applicable operating system/model, language/region, delivery status.
Legal basis: For messages directly related to the game flow (such as game invitations or information that you can continue playing): Art. 6(1)(b) and (f) GDPR (contractual; legitimate interest). And for messages about updates, promotions, campaigns and similar: Art. 6(1)(a) GDPR (consent) in conjunction with the applicable national implementations of Art. 5(3) ePrivacy Directive for messages such as BiQui promotions and campaigns.
Storage period: The Firebase Installation ID is used until deletion by us or uninstallation/reset of the app. After our deletion trigger, Google typically removes the associated data from live and backup systems within up to 180 days. Firebase Cloud Messaging stores message content only until delivery or until the TTL expires (max. 28 days); after that, Google does not retain it.
Withdrawal/deactivation: You can disable push notifications at any time in your device’s system settings (notifications) or in the app settings, or revoke the permission. Please note that if you disable them, essential game functions—such as invitations—may be received too late or only with delay.
This Privacy Policy is from December 19, 2025. The game and the website are continuously improved through further development and improvements. Therefore, changes to this Privacy Policy and Privacy Agreement may become necessary.
