DayBorder: Tax & Schengen Days

Your photos already know how many days you were abroad. DayBorder rebuilds years of travel history in seconds — on your phone, nothing uploaded.

How many days were you out of the country last year? You don't know. Your photos do.

DayBorder reads only the place and date tag stored next to each photo and rebuilds your travel history — years of it, in seconds. No typing trips into a spreadsheet, no GPS running in the background.

WHO IT IS FOR • The 183-day tax residency rule and local day thresholds • The Schengen 90/180 rule, evaluated per day (historical accessions handled) • UK statutory residence test day counts • US physical presence (FEIE, 330 days) • Permit and citizenship minimum-presence requirements

PRIVATE BY ARCHITECTURE • No photo is ever opened, viewed or uploaded — only the place and date tag is read • Coordinates are resolved on the device, then discarded; only a country and a date are kept • No account, no cloud copy of your data, no background location • Network use: your app store (subscription) and anonymous usage statistics — your days, countries and photos are never sent

HONEST NUMBERS Days with no evidence are never guessed. They are shown as an honest range and turned into questions you can actually answer — "which day did you fly?" — so your counts are defensible, not decorative.

DAYBORDER PLUS • Track every limit at once, side by side • Test a trip before you book it, and get the latest date that still works • Warnings before you cross a threshold, not after • Accountant-ready PDF/CSV day log showing how every single day was determined

The free tier is real: one limit, your full calendar, manual trips and corrections — forever.

DayBorder is a record-keeping tool, not tax or legal advice.
