Is My Data Secure?

How AI Tax Accountant protects your financial documents — encryption, infrastructure, access controls, and what you can do to harden your own account.

Yes. Your financial documents are encrypted in transit and at rest, isolated from other firms at the database level, and stored on infrastructure operated by SOC 2 Type II–compliant providers. Below is a plain-English summary of the controls in place and the steps you can take to harden your own account.

Encryption

  • In transit: All traffic between your browser and our servers is encrypted using TLS 1.2 or higher.
  • At rest: All files in storage and rows in the database are encrypted using industry-standard encryption managed by our cloud provider.
  • Payments: Card details are handled directly by Stripe — we never store full card numbers.

Infrastructure

  • Database, authentication, and file storage run on Supabase, hosted in SOC 2 Type II–compliant data centers.
  • Application backend runs on Render.
  • AI classification calls go to the Anthropic Claude API. Per Anthropic policy, your data is not used to train their models.

Access Controls

  • Row-level security policies on the database enforce strict isolation — one firm cannot read another firm's data.
  • Multi-factor authentication (MFA) is enforced for all administrative and staff accounts.
  • Significant actions (uploads, downloads, role changes) are written to an audit log.
  • Every uploaded file is scanned for malware and validated against MIME type and a 20 MB size limit before processing.

What You Can Do

  • Use a unique, strong password for your account (12+ characters, not reused elsewhere).
  • Turn on two-factor authentication from Settings → Security → Two-Factor Authentication.
  • Use the Session Settings → Auto Sign-Out toggle to log out automatically on shared devices.
  • Only invite team members you trust, and remove access promptly when someone leaves.

If you suspect your account has been compromised, change your password immediately and email support — we will review the audit log with you.
