- Strictly Necessary Cookies: Essential for core Platform functionality such as maintaining your logged-in session, processing transactions, and enforcing security measures. These cannot be disabled without breaking core Platform features.
- Performance and Analytics Cookies: Used to collect anonymised data about how players navigate and interact with the Platform, helping us identify areas for improvement. No personally identifiable information is collected by these cookies.
- Functional Cookies: Used to remember your preferences such as language settings, display options, and recently viewed game categories to provide a more personalised experience on your return visits.

7. Data Security
5777b takes the security of your personal data seriously. We implement a range of technical and organisational measures designed to protect your data against unauthorised access, accidental loss, destruction, disclosure, or alteration. These measures include:
- SSL/TLS encryption for all data transmitted between your device and the 5777b Platform.
- Encryption of sensitive personal data at rest, including identity documents and financial records.
- Access controls that restrict employee access to personal data to those with a genuine operational need.
- Regular internal security reviews and vulnerability assessments of Platform infrastructure.
- Two-factor authentication options available to players to strengthen account security.
- Monitoring systems that detect and alert on suspicious login activity, unusual transaction patterns, and potential security incidents in real time.
Whilst 5777b employs robust security measures, no method of data transmission or storage over the internet can be guaranteed to be completely secure. In the event of a data security incident that is likely to result in a risk to your rights and freedoms, 5777b will notify affected players and take all appropriate remedial action without undue delay.
Players are also responsible for maintaining the security of their own account credentials. You should use a strong, unique password for your 5777b account and must not share your login details with any other person. If you suspect unauthorised access to your account, contact our support team immediately at [email protected].
8. Data Retention
5777b retains personal data only for as long as is necessary to fulfil the purposes for which it was collected, or as required by applicable legal and regulatory obligations. The following general retention principles apply:
- Active Accounts: Personal data associated with an active player account is retained for the duration of the account's existence on the Platform.
- Closed Accounts: Following the closure of a player account, 5777b retains relevant personal and transactional data for a period necessary to comply with anti-money-laundering, fraud prevention, and legal record-keeping obligations.

Upon expiry of the applicable retention period, personal data is securely deleted or anonymised in a manner that renders re-identification impossible. Anonymised, aggregated data may be retained indefinitely for statistical and analytical purposes without restriction.
