Last updated: March 29, 2026

Proanauta ("we", "our", "the app") is a nautical navigation calculator available on iOS, Android, and the web at proanauta.app. We take your privacy seriously. This policy explains what data we collect, why, and your rights.

The following data is stored locally on your device and is never sent to us:

This data uses IndexedDB/localStorage. We never have access to it. Deleting the app deletes this data.

2. Data collected by third-party services
