The Post-Brexit Reality

The 183-Day Tax Trap

Staying more than 183 days in countries like Spain or France doesn't just violate your visa—it legally turns you into a tax resident. Our tracker prevents accidental wealth tax exposure.

The EES Border System

With the EU's new Entry/Exit System (EES) rolling out, biometric gates will calculate your 90/180 limit in milliseconds. Human error on a spreadsheet is no longer an option.

100% Offline Architecture

Your travel data is highly sensitive. Unlike cloud-based apps, the Sovereign Tracker runs locally on your device. We do not track, store, or see your data. Absolute zero-knowledge.

Secure Your Compliance

Choose the architecture that fits your global footprint. One-time payment. No subscriptions.
