Letsafely is a placeholder name only. Stage 1 is a free, no-data tool.

What this stores: nothing leaves your device.

Free calculator — stays on this device

Gap-to-reminder calculator

Paste an Airbnb, Booking.com or Vrbo iCalendar (.ics) export, or type date ranges. Letsafely finds vacant gaps and builds flush, alarm-test and optional descale reminders. You can download those reminders as an .ics file. Summaries, descriptions and guest details are ignored. Only dates and booking references (UID) are used. Blocked or “not available” events count as booked.

Paste .ics text, or one line per stay as YYYY-MM-DD to YYYY-MM-DD. The end date is the checkout day. No network calls are made.

Tasks before this date are hidden. Use the format YYYY-MM-DD.
