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 currently uses cookies and similar storage technologies only for a limited, function-oriented set of purposes that are necessary for the operation of the Service. These 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.
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 only to remember the user’s choice regarding the display of the cookie notice on the same browser and device.
Tychefy does not currently use analytics or marketing cookies on the public website. If non-essential analytics, advertising, or similar technologies are introduced in the future, this Policy will be updated and, where legally required, consent will be requested before such technologies are activated.
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 does not currently activate non-essential analytics or marketing cookies on the public website. If non-essential measurement, analytics, advertising, or similar technologies are introduced in the future, Tychefy will update this Policy and implement any consent mechanism required by applicable law before activation.
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.
Because Tychefy currently uses only strictly necessary cookies and similar technologies on the public website, there is no granular non-essential cookie control centre at this time.
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.
