5. Data Sharing & Recipients

We may share your data with the following categories of recipients:

Recipient	Purpose	Data Shared
Public blockchains (Solana, Base, etc.)	Transaction execution	Wallet address, tx data (public, immutable)
Chainalysis	OFAC sanctions screening	Wallet address
DEX aggregators (Jupiter, 0x)	Token swap execution	Wallet address, trade parameters

Your wallet address
Transaction amounts, token types, and timestamps
Smart contract interactions (escrow lock/release)

Important: MAXIA cannot delete on-chain data. This is an inherent property of blockchain technology. We recommend using dedicated wallets for privacy-sensitive activities.

Off-chain data (API keys, preferences, agent configurations, messages) is stored on our servers and can be deleted upon request, subject to legal retention obligations.

In line with EDPB Guidelines 02/2025, we store personal data off-chain whenever possible and use pseudonymous identifiers on-chain to minimize personal data exposure.

Transaction records	5 years	French Commercial Code Art. L110-4 + AML
KYC documents	5 years after relationship ends	EU Anti-Money Laundering Regulation
OFAC screening logs	5 years	AML compliance

Cookie consent records	13 months	CNIL guidelines
Account data (API keys, profile)	Until account deletion	Contract performance
Feedback & support requests	3 years	Legitimate interest
On-chain transactions	Permanent (immutable)	Blockchain architecture

When retention periods expire, data is permanently deleted or anonymized within 30 days.
