Privacy Policy

This Privacy Policy explains what information Felix (“Felix,” “we,” “us”) collects when you use the Felix API, SDKs, MCP server, website, and related services (the “Service”), how we use it, and your choices. By using the Service, you agree to this Policy. Felix is non-custodial; we do not have access to your wallet’s private keys.

You provide: account details such as an email address; API key labels and settings; support communications; and, if applicable, billing information (processed by our payment providers, not stored by us in full).

Automatically: API usage and logs (endpoints called, timestamps, rate-limit and error data), device and connection data such as IP address and user agent, and cookies or similar technologies on our website.

On-chain and trading data: public wallet addresses associated with your account, deposit and withdrawal addresses, and records of orders, fills, and positions routed through the Service. Blockchain data is inherently public.

What we do not collect: we do not have your wallet’s private keys or seed phrase in a form we can read; key material is encrypted such that the operator cannot unilaterally access it.

We use information to: provide, operate, secure, and improve the Service; authenticate keys and enforce rate limits and spend controls; route and settle trades and process deposits/withdrawals; detect, prevent, and investigate fraud, abuse, and security incidents; comply with legal obligations; communicate with you about the Service; and analyze usage to improve reliability and features. We may use aggregated or de-identified data for analytics and product development.

We share information with: service providers (infrastructure, security, analytics, email, payments) who process data on our behalf under contract; trading venues and networks as needed to route and settle your transactions; and authorities when required by law, legal process, or to protect rights, safety, and the integrity of the Service. If we are involved in a merger, acquisition, or asset sale, information may transfer as part of that transaction. We do not sell your personal information for money.

We keep information for as long as needed to provide the Service and for legitimate business, legal, tax, accounting, and security purposes. Trading, transaction, and audit records may be retained for longer periods where required by law. Public blockchain records cannot be deleted by us.

We use technical and organizational measures designed to protect information, including encryption of sensitive key material. No system is perfectly secure, and we cannot guarantee absolute security. You are responsible for protecting your own keys and credentials.

Depending on where you live, you may have rights to access, correct, delete, or port your personal information, to object to or restrict certain processing, and to withdraw consent. Residents of the EU/UK (GDPR) and California (CCPA/CPRA), among others, have specific rights. To exercise them, contact privacy@felix.trade. We will respond as required by applicable law. Note that some data (for example, blockchain records or records we must keep by law) cannot be deleted.

Our website may use cookies and similar technologies for functionality, preferences, and basic analytics. You can control cookies through your browser settings; disabling them may affect some features.

The Service is not directed to anyone under 18, and we do not knowingly collect information from children. If you believe a child has provided us information, contact us and we will delete it.

We may process and store information in countries other than where you live, including the United States. Where required, we use appropriate safeguards for cross-border transfers. By using the Service, you understand your information may be transferred to and processed in such locations.

We may update this Policy from time to time. If we make material changes, we will take reasonable steps to notify you and update the effective date above. Your continued use of the Service means you accept the updated Policy.
