# Where - E2EE Realtime Location Sharing

Where - E2EE Realtime Location Sharing is a product idea in the other category at difficulty 4/5, with moderate market demand and an estimated revenue potential of $1k-5k/mo.

## Summary

A privacy-first family and friend location sharing app with end-to-end encryption using Signal-style double-ratchet protocol. No persistent identifiers, ephemeral mailbox tokens, and session-based pairing for maximum privacy.

## Why this is interesting

Post-Snowden privacy fatigue has quietly matured into genuine consumer willingness to pay for it, and Apple's own AirTag stalking scandals plus Google's location data monetization lawsuits have pushed family location sharing into an uncomfortable spotlight — the timing for a credible privacy-first alternative is reasonable. Life360 is the obvious incumbent and has faced sustained criticism for selling user location data to data brokers, which is exactly the trust gap this product targets. The $1k–5k/mo revenue band is plausible only as a bootstrapped solo project with a small paid tier, since location sharing is notoriously difficult to charge for when Google Maps sharing and Find My are free and deeply integrated into existing platforms most families already use. The single most likely failure mode is distribution: building the crypto correctly is hard but tractable, whereas convincing a family to abandon the app already on everyone's phone requires a coordinated switching moment that almost never happens organically.
