Privacy Policy
Privacy-by-design meets blockchain transparency. Learn how we protect your data using zero-knowledge proofs and selective disclosure.
HalalFi commits to protecting your privacy on our Sharia-compliant blockchain platform. This policy details how we handle personal data amid blockchain's public, immutable nature using privacy-by-design,zero-knowledge proofs (ZKPs), and selective disclosure to minimize exposure while enabling compliant operations.
Information We Collect
Pseudonymous wallet addresses, transaction hashes, and smart contract events. This data is public by design and immutable on the blockchain.
Potential KYB details (Investee Company Name, ID and Docs, address) stored encrypted off-chain. Zero-knowledge proofs (ZKPs) prove compliance without revealing data.
IP addresses (anonymized) and platform interactions. No central logs—decentralized nodes handle syncing.
How We Use Your Data
KYC/AML via ZKP verifiers (e.g., prove age >18 without sharing date of birth).
Mudarabah execution and profit distribution via audited smart contracts.
Resolved on-chain with oracle-fed arbitration.
Aggregated analytics only—no personal profiling. Opt-in only for notifications.
Data Sharing & Transparency
Service providers (e.g., node operators) see only necessary encrypted data under Data Processing Agreements (DPAs).
Transactions are public and pseudonymous. We advise wallet best practices (e.g., using fresh addresses).
Disclosed only under court order—no proactive sales of data.
Standard Contractual Clauses (SCCs) and ZKPs ensure data adequacy.
Security Measures
AES-256 and ECDSA for off-chain data; immutable on-chain audits.
ZKPs/SNARKs verify facts (e.g., Sharia compliance) without revealing underlying data.
Multi-signature wallets and DAOs prevent single-point failures.
Regular audits via ImmuneFi for smart contracts with active bug bounties.
Your Privacy Rights
Query on-chain data and request off-chain exports anytime.
Off-chain deletion available (on-chain transactions are immutable—pseudonymity advised).
Download your data via wallet explorers.
Opt-out of non-essential processing at any time.
Cookies & Retention
Essential cookies for wallet connection and UI state. Analytics cookies are anonymized with no on-chain linking.
On-chain data is permanent (inherent to blockchain). Off-chain data retained for minimum AML compliance periods, then securely purged.
