Safe Harbor privacy

Last updated 7 October 2026

Safe Harbor prepares your companies' tax returns and your own from papers you upload. It is run by James Layfield, on his own computer in Miami.

Signing in

You sign in with your Google account, through Cloudflare. Safe Harbor learns your email address and nothing else from Google.

What it keeps

What you upload and what you answer: your papers, the figures read from them, and your answers, in your own estate. Only you, and anyone you invite, can see it. It is stored on an encrypted drive. Social Security numbers are kept in that computer's keychain; pages show the last four only.

When you ask for help

If you ask for help with a question, that question and the figures it needs are sent to Claude, by Anthropic, to explain the choices.

What it never does

It never sells, shares or uses your data for advertising. It never files or sends anything for you.

Google Calendar

For the account holder who allows it, Safe Harbor uses the Google Calendar API to add filing deadlines to their own calendar.

Safe Harbor's use of information received from Google APIs follows the Google API Services User Data Policy, including the Limited Use requirements.

Stopping it

The permission can be removed at any time at myaccount.google.com/permissions. After that, Safe Harbor can no longer reach the calendar.

Leaving

Ask, and your estate is deleted.
