We do not sell your personal data.
We may share personal data with:
- Service providers / processors: Hosting providers, cloud infrastructure, KYC/AML verification providers, payment processors, analytics providers, customer-support tools, and email service providers. These parties process data only on our instructions and under confidentiality obligations.
- Bot protection: Cloudflare, Inc. provides bot protection (Cloudflare Turnstile) on our registration and sign-in forms. When those forms load, Cloudflare receives browser, device, and connection signals, including your IP address, so it can tell people from automated traffic.
- Mining-related partners: Mining-pool operators or hosting partners as necessary to deliver services (e.g., hashrate attribution or payout routing). Wallet addresses and related on-chain data may be visible publicly.
- Corporate group / affiliates: Related entities under common control for internal administrative purposes.

International transfers (including outside Singapore or the EEA) are protected by appropriate safeguards such as standard contractual clauses, adequacy decisions, or equivalent measures under applicable law.
6. Data Retention
We retain personal data only as long as necessary for the purposes described, including:
- Account and transaction data: for the duration of the relationship plus a period required for legal, accounting, tax, or regulatory obligations (typically several years after account closure or last activity).
- KYC/AML records: as required by anti-money-laundering laws (often 5–7 years or longer).
- Technical logs and analytics: shorter periods, usually anonymized or deleted after a few months to years.
- Marketing data: until you withdraw consent or unsubscribe.
When data is no longer needed, we securely delete or anonymize it.
7. Data Security
We implement appropriate technical and organizational measures to protect personal data against unauthorized access, alteration, disclosure, or destruction. These include encryption in transit and at rest where appropriate, access controls, secure authentication (including 2FA options), regular security assessments, and staff training.
No method of transmission over the Internet or electronic storage is 100% secure. You are responsible for keeping your account credentials confidential. We are not responsible for breaches resulting from your failure to protect login information or from public blockchain transparency of wallet addresses and transactions.
