Security

Your return is the most sensitive thing you'll upload this year.

We treat it that way.

Encrypted at rest

All uploaded returns are encrypted at rest in Supabase Postgres with key rotation.

Row-level security

Supabase RLS enforces that only you and your assigned CPA reviewer can read your return data.

SOC 2 in progress

We're actively pursuing SOC 2 Type I attestation for 2026. Our subprocessors (Stripe, Resend, Anthropic) are SOC 2 attested today.

7-year audit log

Every action is logged with actor, IP, user agent, and timestamp. Logs are retained per IRS guidance.

Resend for transactional email

Account verification and CPA correspondence are delivered via Resend, never sold or shared.

Powered by Claude — never trained on your data

Anthropic does not train on Claude API traffic. Your return content is not used to improve any model.
