As a privacy-focused user, I currently have no safe way to track my family's location. Existing apps like Life360, Google Maps, or Apple Find My store location history on their servers, meaning the provider can see exactly where my family goes, when, and for how long. This creates a massive privacy risk and contradicts the "privacy by default" philosophy I trust Proton for.

The Solution: Please introduce a Family Location Tracking feature within the Proton ecosystem (integrated into Proton Pass, Drive, or as a standalone module in Lumo) that offers:

True End-to-End Encryption (E2EE): Location data is encrypted on the device. Only family members with keys can decrypt it. Proton servers should never see raw location data.
Real-Time Updates & History: A secure map view showing live locations and travel history, accessible only to authorized family members.
Geofencing Alerts: Secure notifications when family members arrive at or leave specific zones (e.g., school, home).
Cross-Platform: Works seamlessly on iOS, Android, and Web.
Why This is Critical: There is a huge demand for a "Life360 killer" that respects privacy. Families are currently forced to choose between safety and surveillance. A Proton solution would be the gold standard, likely driving significant upgrades to Lumo Plus or Visionary plans.

Impact: This would complete the Proton ecosystem, protecting not just our digital data, but our physical safety and movement privacy.
