Building E2EE for Our Open-Source Location Tracking App—Looking for Advice!

Hi everyone! 👋

A little while ago, I shared an update about Group Track, our open-source app that helps groups share their locations in real-time. The response from this community was incredible—thank you for all the feedback and support!

We’ve now started working on a big feature: end-to-end encryption (E2EE) for location sharing. Our goal is to keep location data private and secure while ensuring the app remains simple and user-friendly.

Since this is a tricky area, we’d love to hear your thoughts! Have you worked on E2EE or similar privacy-first features? Any advice or resources would be greatly appreciated.

The project is open source, so if you’re curious or want to contribute, here’s the repo: https://github.com/canopas/group-track-android

Thanks again for all the encouragement so far—looking forward to hearing your ideas!
