Privacy Policy

Domi (domi.tax) · Last updated October 3, 2026

Domi keeps a day-by-day record of which U.S. state, county or country you were in, so you can see how many days you've spent in each place for tax-residency purposes. This page explains exactly what that involves.

What we collect

• Where you were, at county level only. The iPhone app reads your location and converts it on your phone to the county (or, outside the U.S., the country) you're in. Only that county or country, with the time, is sent to our server. Your exact location, street address or GPS coordinates are never stored or sent anywhere.
• Your account. Your email address, and how you sign in (Apple, Google, or email and password). A password is stored only as a secure one-way hash, never in readable form.
• What you enter. Your home locations (entered as a ZIP code or city and kept only as state and county), your main home state, the day limits you choose to watch, your plans, and any corrections you add for days that weren't recorded.
• A notification token for your phone, so the server can briefly wake the app to check your location while it's closed.

How we use it

Only to run Domi for you: counting your days, showing your reports, and emailing you reports or codes when you ask. We don't sell your information, we don't use it for advertising, and we don't track you across other companies' apps or websites.

Who we share it with

No one else sees your record. We use a few service providers only to run the service:

• Our server host, where your record is stored.
• An email delivery service, to send the emails you ask for (sign-in codes and reports).
• Apple, to deliver the notifications that wake the app.
• A geocoding service, only when you look up a home by ZIP code or city. It receives only what you type.

Keeping it safe

Your data travels only over encrypted connections (HTTPS). Your record is stored as an append-only log with a tamper-evident chain, so any later change to past entries can be detected. The whole purpose is to give you an accurate, trustworthy record.

Your choices

• You can turn location access off at any time in your iPhone's Settings. Domi then stops recording.
• You can delete your account from the app (Settings ▸ Delete my account). That permanently removes your account and your entire record from our server, and clears what the app kept on your phone.
• You can email yourself a PDF report of your record from the Reports screen at any time.

Children

Domi is meant for adults managing their own tax residency and isn't directed at children under 13.

Not tax advice

Domi counts days and shows how close you are to limits. It doesn't give tax advice or decide where you're a resident. Please talk to a tax professional about your situation.
