Tax-residency day tracking for iPhone
Every day, accounted for.
Residay records which country you are in each day, keeps a defensible presence ledger with evidence, and evaluates it against tax-residency, visa, and citizenship day-count rules. It computes what is computable, asks you about the rest, and never issues a verdict — it shows you rule conditions, counts, and the trail behind them.
Verifiably private
No backend. No analytics. An empty App Store privacy label — "Data Not Collected" — that you can check for yourself. The app never transmits your history; the only copy that moves is an encrypted backup you choose to make.
Correct on the hard rules
The UK midnight test with deeming. Cyprus arrival-in, departure-out. The Schengen 90/180 rolling window with breach projection. Counting conventions are encoded per rule and tested against golden fixtures.
Accountant-grade exports
Per-counter CSV with attribution reasons, and a branded PDF report — counts, conventions applied, day table, attestations on record — designed to hand to your accountant.
The privacy promise
The only honest place for your location history is hardware you own.
Residay makes no outbound network calls except App Store purchases and links you choose to open. Coordinates are stored rounded to roughly 110 metres — enough to attribute a country, no more. This website sets no cookies; the only things that leave your browser are a cookieless page count and, if you choose to sign up, your email address to our own relay. The calculators run entirely in your browser.
Pricing
Free to count. Premium to reconstruct, report and export.
Manual trips and two counters are free. Premium adds automatic tracking, photo backfill, unlimited counters, full history, CSV and PDF exports, and encrypted backup — €39.99/year or €5.99/month.
