3. Types of cookies used

The following categories of cookies and similar technologies may be used in the Service:

a) Strictly necessary cookies are required for the proper operation of the Service. They cannot be disabled from the consent banner because without them it would not be possible to provide basic features, such as logging in, session maintenance, security, and remembering your cookie choices.

b) Functional cookies allow remembering selected User settings and preferences that are not strictly necessary for the operation of the Service. They are used only when a given feature is implemented and requires User consent.

c) Analytical cookies are used to measure traffic in the Service, analyze how the Platform is used, detect usability issues, and improve the operation of the website. Analytical cookies are activated exclusively after obtaining your consent.

d) Marketing cookies may be used to measure the effectiveness of promotional activities, build audience groups, or present tailored advertising messages. FanStage does not currently use marketing cookies unless explicitly stated otherwise in the consent banner and this Cookie Policy.

4. Strictly necessary cookies and related technologies

FanStage may use necessary cookies or similar technologies, including the browser's local storage (localStorage), in order to:

  • logging in and maintaining the User's session;
  • authentication using Supabase Auth;
  • protecting the security of the Service and preventing abuse;
  • remembering the User's decision regarding cookie preferences;
  • the proper operation of forms and basic functions of the Service.

This category may include, in particular:

  • cookies or tokens session tokens related to Supabase Auth, including cookies with the sb- prefix;
  • technical recording of consent preferences in cookies or the browser's local storage;
  • technical identifiers necessary for the proper operation of the Service.

Necessary technologies are not used for marketing profiling.

5. Analytical cookies: Google Analytics 4

If you consent to analytical cookies, FanStage may use Google Analytics 4, an analytical tool provided by Google.

Google Analytics 4 helps us understand traffic in the Service and how its functionalities are used, in particular the number of visits, traffic sources, visited subpages, and general interactions with the Service.

Google Analytics 4 is not launched before obtaining consent for analytical cookies. GA4 uses its own cookies to distinguish users and a given user's sessions.

6. Analytical cookies: Microsoft Clarity

If you consent to analytical cookies, FanStage may use Microsoft Clarity, a tool for analyzing the use of the Service, including heatmaps and aggregate data about interactions with the interface.

Microsoft Clarity is not launched before obtaining consent for analytical cookies. For users from the European Economic Area, the United Kingdom, and Switzerland, a valid consent signal must be passed to Clarity.

7. List of technologies used

The following list is informational and presents the main cookie technologies used on the Platform:

  • Strictly necessary: sb-* (Supabase) – Logging in, session maintenance, authentication, and security (Duration: Session or period specified by Supabase configuration).
  • Strictly necessary: Cookie preference save (FanStage) – Remembering cookie decisions (Duration: [TO BE FILLED IN after CMP implementation]).
  • Analytical: _ga, _ga_* (Google) – Traffic and usage analysis in Google Analytics 4 (Duration: According to GA4 configuration; up to a maximum of 25 months).
  • Analytical: Microsoft Clarity cookies (Microsoft) – Analysis of interaction and usability of the Service (Duration: [TO BE FILLED IN after Clarity implementation]).

The duration of cookies in Google Analytics 4 can be configured by the administrator ranging from immediate expiration up to a maximum of 25 months.

8. Legal basis for using cookies

We use necessary technologies because they are required to transmit a communication over a telecommunications network or to provide a service explicitly requested by the User, in particular logging in, session maintenance, and ensuring security.

Functional, analytical, and marketing cookies, if used, are applied exclusively after obtaining your prior consent.

The lack of consent for functional, analytical, or marketing cookies does not prevent the use of the basic features of FanStage. Cookies required to transmit a communication or provide an explicitly requested service are exempt from the obligation to obtain consent.

9. Managing consent and disabling cookies

On your first visit to the Service, we display a consent banner that enables:

  • accepting all cookie categories;
  • rejecting all non-mandatory cookie categories;
  • choosing individual cookie categories;
  • learning about the purposes of using cookies.

Consents for non-mandatory cookies are not checked by default.

Google Analytics 4, Microsoft Clarity, and other non-mandatory technologies are launched exclusively after accepting the appropriate cookie category.

The User may change or withdraw their consent settings at any time by clicking the "Cookie Settings" link available in the footer of the Service. Withdrawing consent is just as easy as granting it.

Regardless of the settings available in the Service, you can block or remove cookies from your browser settings. However, this may affect the operation of some features of the Service, in particular the ability to log in or maintain a session.

Requirements for valid consent include informing the user beforehand, expressing consent through an active action, the ability to choose categories, and an easy way to revoke the decision.

10. Data recipients and transfer outside the EEA

Data collected using cookies may be transferred to technology providers used in the Service, in particular:

  • Supabase - regarding technologies necessary for authentication and Account operation;
  • Google - in case of consenting to Google Analytics 4;
  • Microsoft - in case of consenting to Microsoft Clarity, if the tool is implemented;
  • the consent management tool provider, if implemented.

Due to the global nature of the providers, data may be transferred outside the European Economic Area, including to the United States.

In such a case, we apply required by law safeguards for the transfer, in particular standard contractual clauses, adequacy decisions, or other mechanisms provided for in the GDPR.

More information about data recipients, data transfers, and your rights can be found in the Privacy Policy.

11. Changes to the Cookie Policy

The Cookie Policy may be updated in the event of changes in legal provisions, technologies used in the Service, the scope of cookies, or the method of managing consents.

We may inform about significant changes through a communication in the Service, updating the document date, or in another appropriate manner.
