Stayguard: Schengen 90/180

NOT A GOVERNMENT APP
Stayguard is not affiliated with, endorsed by, or representing any government or government agency (e.g. the EU, UK Home Office, HMRC, USCIS, IRS, IRCC). It is an independent day-counting tool. It is not legal or tax advice; confirm important decisions with the authority or an adviser.

Know exactly how many days you have left, before you book the flight.

Stayguard counts the days that decide where you may stay: Schengen 90/180, 183-day tax residency, UK ILR absences, US citizenship (N-400) and substantial presence, Canadian PR and citizenship. 121 preset rules in all, each checked against an official source. Add each trip once, and every rule reads the same record.

THE ANSWER IN ONE GLANCE
• A big number: days left in the rolling window, and the last safe day.
• A calendar and day strip showing which days count and when they come back.
• A world map of everywhere you have been, and a year in review.
• Alerts before you reach a limit, never after.
• A passport control screen: your 90/180 count and every entry and exit, in English for the officer.

KNOW BEFORE YOU BOOK
Test a trip against every rule at once: safe, how many days to spare, or the exact day it breaks a rule. Planning a visa run? Stayguard finds the earliest day you can come back.

EVERY RULE YOU LIVE BY
• Schengen 90/180 calculator, entry and exit days counted
• 183-day tax residency for any country and tax year
• UK statutory residence test and ILR 180-day absence limit
• US N-400 physical presence and substantial presence test
• Canada PR residency obligation and citizenship count
• Visa-free limits from the rule library, or your own limit
• Residence permits, long-stay visas and trips with an EU family member left out of 90/180
• Crew-duty days can be left out of tax counts

LESS TYPING (PRO)
• Automatic stays: Stayguard notices border crossings and suggests the stay. Nothing is added without you.
• Import old trips from your calendar, boarding passes, Google Timeline, flight-tracker logs, a spreadsheet or photo locations.
• Family profiles, each with their own days and rules.
• Passport and visa expiry reminders, with a validity check for every trip.
• Trip PDFs for N-400, UK and Canadian applications, plus CSV and Excel.
• A Home Screen widget with your days left.

PRIVATE BY DESIGN
No account, no ads, no analytics. Your travel log lives on your device; only the country is kept, never your location. Documents can be locked with your fingerprint, face or screen lock. Back up to a file any time; Pro does it automatically, to your own storage.

FREE vs PRO
Logging stays, the calendar, the map, trip planning, documents and backups are free forever, with one rule guarded. Pro guards every rule and adds automatic stays, imports, family profiles, reminders, PDFs and widgets. Monthly, yearly (3-day free trial) or one-time lifetime.
