Privacy policy

Last updated 9 November 2026

TLDR

Lights! Nav savvy collects no data, never uses the internet, and every permission it asks for can be safely refused: the app keeps working.

Explainer

Thank you for using Lights! Nav savvy. You trust it with a place on your phone or tablet, and it should respect that. This policy is long only because we wanted to be clear: the app doesn’t collect anything about you.

No data is collected

The app has no accounts, no sign-in, no analytics, no advertising, no tracking and no crash reporting. It contains no third-party services that could do any of that. Nothing about you is gathered, stored on a server, sold, shared or passed on to anybody, because the app has nowhere to send it and nothing to send.

What you do in the app stays on your device. If you delete the app, it is gone together with the app.

No internet

Lights! Nav savvy has nothing to do with the internet. It does not request network access, it does not talk to any server, and it works the same way with your connection on, off, or somewhere out at sea with no signal at all.

Permissions

Depending on your device, the app may ask for some permissions, for example to make its work more convenient. We would like to be clear about them:

  • You can refuse any of them. Nothing in the app will break. Every function keeps working, and nothing is locked behind a permission.
  • You can change your mind at any time in your device settings, and allow or withdraw a permission whenever you like.
  • Whatever you allow is used on your device only. It is not recorded, saved to a server or sent anywhere.

Children

The app collects no data from anyone, so it collects none from children either. It is safe for all ages in this respect.

If this ever changes

We don’t plan to change any of this. If the app ever needs to work differently, this page will be updated first, and the date at the top will change, so you can always see when it was last revised. The app will not start collecting data without this policy saying so beforehand.

Questions

If something here is unclear, or you just want to say hello, write to apps@y-b.one. We are glad to hear from you.

Fair winds!
