The MostBet privacy policy explains in one place what data the platform collects, why it uses cookies, how it protects your information, and how you can request access or deletion.

This MostBet privacy policy sums up, in plain language, what information the platform processes, what it is used for, and how you can request access, correction or deletion. The goal is simple: you should know what happens to your data before you use the casino, the slots or sports betting.
The data we process is what you give us yourself when you sign up and use your account: identification and contact details, date of birth when it is needed to confirm your age, plus access information such as device, approximate IP address and session logs. It also covers data generated by your activity, such as betting history, open bets, transactions and messages sent to support.
Each type of data has a purpose tied to running your account — nothing is collected without a practical use.
The site uses cookies and similar technologies to keep your session active, remember preferences and measure page performance. Without them, basic features like login, switching between the Casino, Slots and Sports sections and the bet slip would not work properly.
In practice, cookies fall into three groups: essential (login and security), preference (language, filters in the online slots catalogue and the betting sections) and measurement (understanding which pages get the most use and where errors happen). You can block or delete cookies in your browser settings, but some features may stop responding — including access to your account.
Data is used to deliver the service: open and protect your account, process deposits and withdrawals, credit first deposit bonuses, free spins and seasonal campaigns, and provide support in Portuguese from sign-up through to withdrawal.
Practical examples of use:
About campaigns: the first deposit bonus, free spins and seasonal promotions appear inside the player’s account and are activated in a few taps. The rules of each campaign are described alongside the bonus itself, and activation conditions can also be found on the casino bonus page. Deposit and withdrawal details are gathered in the casinos that pay via Pix section.
Sharing happens only when it is needed to run your account: processing payments, running games from partner providers, measuring the site, and meeting legal requirements or requests from a competent authority. Outside those cases, your data is not sold.
Internally, access is limited to those who need the information to do a job — support, fraud prevention, finance and technical maintenance. Payments, betting history and preferences are gathered in one personal panel, separate for each account, which helps limit who sees what.
Usual measures on platforms of this kind include encrypted connections, role-based access control and monitoring of suspicious activity. They reduce the risk, but no system is foolproof: so use a unique password and never share your login details.
You can request confirmation that your data is being processed, access, correction, portability where applicable, restriction and deletion of your data, and withdraw consent you gave earlier, in line with applicable data protection law.
How to do it: send your request by email to [email protected] or by phone at +55 11 4002-8922, stating the account email and what you want. We may ask you to confirm your identity before we act, precisely so that data is not handed to third parties.
About deletion: you can ask to close your account and have your personal data deleted, but some records may need to be kept to meet legal, tax or fraud-prevention requirements. When that happens, we explain why and for how long the record is needed. General information about how the platform works, the game catalogues and the betting sections remains available on the site’s public pages.
The channel for privacy matters is the same as for support: email [email protected], phone +55 11 4002-8922 and address Av. Paulista, 1374 — Bela Vista, São Paulo — SP, Brazil. Online support runs every day from 08:00 to 00:00 (Brasília time).
The full list of channels is on the MostBet contact page. If your question is about bonuses, games or limits, the same support team answers it.
