About this tracker

schengen.sewlio.com is a free Schengen 90/180-day tracker. Enter your past and planned trips, see how many days you've used in the rolling 180-day window, and check whether a future trip would push you over the limit. Nothing leaves your browser unless you choose to share a link.

Why this exists

Existing Schengen calculators are either out of date, hidden behind ad walls, or fail at the conceptual hard part: visualizing the rolling 180-day window. We built one that does it well and gives it away.

How we pay for it

The calculator itself shows no ads. The surrounding country and nationality pages (where you might land from a search like “Schengen rules for American citizens”) show a small number of standard display ads. That's the entire business model. No paid tier, no gated features, no email collection.

Part of SEWLIO

This is the first product in the SEWLIO traffic factory — a portfolio of small, focused, free web tools. Each tool lives at its own subdomain. Each is built to be the simplest, fastest tool for one specific task.

Not legal advice

This tool is for general guidance only. The 90/180 rule has consequences (refused entry, fines, multi-year bans) and you remain solely responsible for verifying your stay against official sources before traveling. We are not lawyers and this is not legal advice.
