4. Why We Process Personal Data

We process personal data for the following purposes and legal grounds:

Providing and Securing the Website

Technical server data is processed to deliver website content, maintain reliable operation, detect errors, and protect the website against unauthorized access and abuse.

The legal basis is our legitimate interest in operating and securing the website under Article 6(1)(f) GDPR.

Responding to Messages and Support Requests

Information sent by email is processed to answer questions, provide product support, investigate technical problems, and respond to feedback.

Where a message concerns a purchase or a request made before purchasing BiColor, the legal basis may be Article 6(1)(b) GDPR. For general questions and feedback, the legal basis is our legitimate interest under Article 6(1)(f) GDPR.

Optional Cookies and External Content

Where consent is required, optional cookies, embedded media, or analytics are processed under Article 6(1)(a) GDPR.

You may withdraw your consent at any time without affecting processing that took place before the withdrawal.

Legal Obligations and Claims

We may process information when required by law or when necessary to establish, exercise, or defend legal claims. The legal basis is Article 6(1)(c) or Article 6(1)(f) GDPR, depending on the situation.

We do not use personal data collected through this website for automated decision-making or profiling.

5. Cookies and Embedded Content

Necessary Technologies

Some technologies may be necessary to provide requested website functions, maintain security, or remember your privacy preferences. These technologies do not require consent where they are strictly necessary for the service requested by the user.

Optional Cookies

Optional cookies and similar technologies are not activated until you provide consent where required by applicable law.

You can accept, reject, or change your choices through the Cookie Settings link available in the website footer.

Rejecting optional cookies will not prevent you from reading the website, but some external content may remain unavailable.

Some pages may contain videos provided by YouTube, a service operated by Google.

YouTube content is loaded only after you consent to external media. When you load or play a video, Google may receive information such as your IP address, device information, browser data, the page visited, and your interaction with the video.

  • Professional advisers or public authorities — only where disclosure is required by law or necessary to protect legal rights.

These providers may process information only for the relevant service or according to their own responsibilities under applicable data protection law.

When you follow a link to Steam, YouTube, X, or another external platform, that platform becomes responsible for the information it collects from you.

We do not sell personal data.

7. International Data Transfers

The website is hosted in the European Union. Some third-party providers, including Google or Valve, may process information outside the European Economic Area.

Where an international transfer takes place, the provider must use an applicable legal transfer mechanism, such as an adequacy decision, Standard Contractual Clauses, or another safeguard recognized under data protection law.

More information about international transfers is available in the privacy policies of the relevant providers.

8. How Long We Keep Personal Data

We keep personal data only for as long as it is reasonably necessary for the purpose for which it was collected.

Technical website and security logs are retained only for as long as needed to operate and protect the website, diagnose errors, prevent misuse, and investigate security incidents. Logs may be kept longer when they are required to investigate a specific technical or security issue.

Email messages and attachments are retained while they are needed to answer a question, provide product support, investigate a reported problem, or maintain a relevant record of previous communication. Information that is no longer needed is deleted during periodic mailbox reviews, unless longer retention is required by law or necessary to establish, exercise, or defend legal claims.

Cookie consent preferences are retained for as long as necessary to remember the user’s privacy choices or demonstrate that consent was provided.

When personal data is no longer required, it is deleted or anonymized.
