How it works
Log, count, prove.
Three habits that make residency questions easy to answer.
Log your days
Add stays, tap Check in here when you arrive somewhere, or (Pro) import days from your photos or a spreadsheet.
See your counts
Days in each state and country, each state's line, the days you have left, and any days with no entry.
Keep the proof
Download a backup any time. Pro builds an audit-ready report and an expiring link for your accountant.
Stay private
Your log stays in your browser. Sync and sharing are encrypted on your device first.
Private, and sourced.
Matched on your device
Your location is compared with state outlines in your browser.
Rules with sources
Every state's summary cites its statute and links to the tax agency.
End-to-end encrypted
We store only encrypted copies we can't open.
