osis77 is committed to protecting the personal data of every member. This Privacy Policy explains what information we collect, why we collect it, how it is used, and the rights you hold over your own data.
Last Updated: 1 January 2026 | Version: 2.4
These principles summarise osis77's approach to data stewardship. They are not a substitute for the full Privacy Policy set out below — you are bound by the complete policy as a registered member.
osis77 collects only the personal data that is strictly necessary to deliver the Services, verify your identity, process your transactions, and comply with applicable legal obligations. We do not collect data speculatively or for purposes unrelated to your membership.
All personal data held by osis77 is protected by 256-bit TLS 1.3 encryption in transit and AES-256 encryption at rest. Access to member data is restricted to authorised osis77 personnel on a strict need-to-know basis. Security protocols are reviewed and updated regularly.
osis77 does not sell, rent, or licence your personal data to any third party for marketing, advertising, or commercial profiling purposes. Your data is yours. Where third-party service providers process data on our behalf, they do so under strict contractual data-processing agreements.
This Privacy Policy is written in plain, accessible English so that every member can understand exactly what data is collected, for what purpose, and for how long it is retained. We do not bury material disclosures in footnotes or obscure them with legal jargon.
Every osis77 member has the right to request a copy of the personal data we hold about them, to correct inaccuracies, and to request deletion of data we are no longer legally required to retain. Requests are processed within 30 days of receipt.
osis77 retains personal data only for as long as is necessary to fulfil the purpose for which it was collected, or as required by applicable legal and regulatory obligations. Once the retention period expires, data is securely deleted or anonymised in line with our internal data lifecycle policy.

To exercise any of the above rights, please contact osis77 via live chat or by sending a written request to [email protected]. We may need to verify your identity before processing a data rights request. All requests are handled free of charge.

If osis77 becomes aware that Personal Data has been collected from an individual under 21 — whether through a false declaration at registration or any other means — the account will be immediately suspended, all data associated with the account will be deleted, and any deposits or winnings will be forfeited.
If you are a parent or guardian and believe that a minor in your care has registered an account with osis77, please contact our support team immediately at [email protected]. We will investigate and take appropriate action without delay.

However, certain third-party service providers engaged by osis77 — including game studio technology partners and KYC verification providers — may process data on servers located outside Indonesia.
Where Personal Data is transferred to a jurisdiction outside Indonesia, osis77 ensures that appropriate safeguards are in place. These include standard contractual clauses that impose data protection obligations on the receiving party equivalent to those applied by osis77, and, where applicable, adequacy assessments of the destination jurisdiction's data protection framework.
By registering an account with osis77, you acknowledge and consent to the transfer of your Personal Data to third-party processors in other jurisdictions where such transfer is necessary to provide the Services, subject to the safeguards described above.
osis77 reserves the right to update or amend this Privacy Policy at any time to reflect changes in our data practices, applicable legal requirements, or platform functionality.
