Built for the trust your clients place in you.
Tendrill handles client portfolios, custodial data, and conversations on behalf of financial advisors. Here is how we protect that data and who we share it with.
The short version
- Bank-level encryption in transit and at rest.
- Zero data retention on AI queries — never used for training.
- Read-only connections to client portfolio data.
- All data stored in the United States.
How we protect your data
Bank-level encryption
Data is encrypted in transit with TLS 1.2+ and at rest with AES-256. Built on bank-grade infrastructure end to end.
Zero data retention
AI queries run with a zero-retention policy. Nothing you or your clients share is stored on the model side after the response comes back.
No training on your data
Your clients' data is never used to train AI models. It stays in your account and leaves when you say so.
Authentication you control
Self-hosted Better Auth with Google sign-in and SMS verification. No third-party identity vendor holds your credentials.
Vendor security
Every subprocessor we work with is reviewed for security and compliance practices and held to the standards we set for ourselves.
US data residency
Your data is stored in the United States. Our database, hosting, and core providers all operate in US regions.
