Your data is safe with Mezzi

Bank-level encryption. Mezzi has zero access to your money.

How Mezzi secures your data

Bank-level security

All data transmission uses TLS 1.3 encryption protocols. These are the same cryptographic standards required by federal banking regulations and used by major financial institutions worldwide.

No account number storage

Mezzi avoids storing bank account numbers, routing numbers, or account identifiers. We partner with industry platforms like Plaid and Meld, which major banks trust, eliminating the need to access account numbers directly.

How your financial data reaches Mezzi safely

Financial data aggregation partners

Mezzi uses Plaid and Meld for secure bank connections, with industry-standard security practices maintained by these services.

OAuth 2.0 token-based authentication

Your login credentials are never transmitted to or stored by Mezzi. Secure tokens allow read-only access to your financial data.

Your credentials remain private

Banking usernames and passwords are managed exclusively by certified partners. Mezzi staff cannot access or view banking credentials.

Regulatory compliance

SEC compliance requirements

As a registered investment advisor, Mezzi adheres to Securities and Exchange Commission regulations, including security requirements and breach reporting procedures.

Account security controls

Single sign-on authentication

Account access requires authentication through Apple or Google SSO, eliminating password vulnerabilities through enterprise-grade identity providers.

Account disconnection controls

You can disconnect individual financial accounts or delete your entire account anytime. Disconnection immediately removes associated data.

Ad-free experience

Subscription-based model

We aren’t here to sell your data to a third party, today or ever. Our paid plan supports product development while protecting your privacy, unlike free apps that monetize user data.
