Security

Security model

Sensitive tax data should travel only when it has to.

tako.tax reduces server-side tax data exposure by doing document parsing, calculation, project saving, and form generation in the browser during normal preparation.

Server-side exposure is intentionally limited

tako.tax servers are designed to serve:

  • The web application
  • Static assets and WebAssembly bundles
  • Operational logs and scrubbed diagnostics

During normal preparation, they are not designed to hold uploaded documents, extracted values, in-progress returns, generated forms, or tax identifiers entered into the app.

No third-party document extraction in normal prep

Uploaded documents are parsed locally in the browser. tako.tax does not send your tax documents to third-party extraction systems during normal preparation.

Your device still matters

Local-first preparation reduces server exposure, but it does not secure your personal device for you. Use a device you control, keep it updated, use a screen lock, and avoid shared or public computers.
