Tychefy Cookie Policy

This policy explains how Tychefy uses strictly necessary cookies and similar technologies to operate the service, preserve security, support authentication, and remember the user’s cookie-banner choice on the same browser and device.

Last updated: 19/02/2026

This Cookie Policy explains how Tychefy uses cookies and similar technologies when you access or use the Tychefy platform (the “Service”). It should be read together with the Privacy Policy and the Terms of Use. For the avoidance of doubt, EuroJackpot, EuroMillions, Greek Joker, and related modules are features of the same Tychefy service environment, and this Policy applies across those features where the same web infrastructure and processing logic are used.

1. What cookies are

Cookies are small text files placed on your device when you visit a website. They may store identifiers, session state, technical preferences, or security-related information. Similar technologies may include local storage, session storage, pixels, SDK-based identifiers, and server-side session mechanisms.

2. Why we use cookies and similar technologies

Tychefy uses cookies and similar storage technologies for a limited, function-oriented set of purposes. Some are necessary for the operation of the Service, while optional marketing measurement technologies are used only where the user has given the relevant consent. These purposes include:

  • maintaining secure sessions and login state,
  • protecting the Service from abuse, fraud, and automated misuse,
  • supporting essential navigation and account functionality,
  • remembering the user’s cookie-banner choice on the same browser and device,
  • activating optional marketing measurement technologies only after the relevant consent has been given.

3. Categories currently used

At the present time, Tychefy uses the following categories:

  • Strictly necessary cookies and similar technologies: essential for authentication, session continuity, security, fraud prevention, traffic handling, and the basic operation of the Service.
  • Preference storage for the cookie banner: local browser storage used to remember the user’s cookie choice on the same browser and device.
  • Optional marketing and advertising measurement technologies: where the user gives consent, Tychefy may use Meta Pixel to measure visits, understand campaign performance, and support advertising-related attribution.

Optional marketing technologies are not intended to be activated before the user has given the relevant consent through the cookie banner or consent controls.

4. Strictly necessary cookies and authentication technologies

Some cookies and similar technologies are indispensable for the functioning of Tychefy. These may be used to keep you signed in, preserve session integrity, route requests safely, enforce security controls, and protect the Service against malicious activity. Because these technologies are necessary for the provision of the Service, disabling them may materially impair functionality or prevent access altogether.

5. Non-essential technologies

Tychefy may use non-essential marketing and advertising measurement technologies, including Meta Pixel, only where the user has given the relevant consent. These technologies may help measure page visits, evaluate campaign performance, and support advertising attribution.

If the user rejects marketing cookies or does not make a marketing-consent choice, these optional technologies should remain inactive.

6. Third-party providers

Tychefy relies on specialised service providers to support elements of the Service. Depending on implementation, such providers may use cookies or equivalent identifiers that are required for their own service functionality in connection with the operation of Tychefy.

  • Authentication providers: for secure sign-in, account sessions, and identity verification flows.
  • Payment providers: for billing, checkout, fraud prevention, payment confirmation, and subscription administration.
  • Hosting and infrastructure providers: for traffic delivery, caching, system resilience, and operational security.

The exact cookies, similar technologies, and retention logic applied by such providers may vary according to their systems and current implementation. Their own legal documentation may also apply to the extent they act under their own responsibilities for certain processing operations.

7. Retention period

Cookies and similar technologies may persist for different periods depending on their function:

  • Session cookies: deleted automatically when your browser session ends.
  • Persistent cookies or browser storage entries: remain for a defined period until expiry, deletion, or manual removal, where they are needed to remember security-related state or the user’s cookie-banner choice.

Retention is limited to what is reasonably necessary for the relevant purpose. Technical, legal, and provider-specific requirements may affect the exact duration.

8. How you can manage cookies

You can usually control cookies through your browser settings by blocking, deleting, or restricting them. You may also clear local storage and other site data from your browser. However, blocking necessary cookies or similar technologies may cause login failures, session instability, degraded security, or loss of essential Service functionality.

Where optional marketing technologies are available, the cookie banner or consent controls allow the user to accept or reject non-essential marketing cookies. The user may also clear browser storage or site data from the browser settings, although this may reset the saved cookie preference.

9. Do Not Track and similar signals

Browser-based “Do Not Track” signals are not always standardised or technically consistent. Accordingly, Tychefy may not respond uniformly to such signals unless and until a reliable technical or legal framework requires a specific response model.

10. Relationship with personal data

Some cookies or identifiers may constitute personal data or may become associated with personal data when combined with account, billing, technical, or usage information. In such cases, the relevant processing is also governed by the Privacy Policy and by applicable data protection law, including the GDPR where relevant.

11. Security and integrity

Certain cookies and session technologies are used specifically to preserve system integrity, detect suspicious activity, prevent abuse, and reduce security risks. These functions are integral to the safe delivery of the Service and may operate continuously while the Service is being used.

12. Changes to this Policy

We may update this Cookie Policy from time to time in order to reflect technical, legal, or operational changes. The current version will be published on this page together with the date of last revision.
