locate. Location sharing the server cannot watch.

Family location sharing is the harder problem: it needs a server. Every existing app solved that by letting the server see everything, then selling what it saw. locate solves it by building the server blind. End-to-end encrypted. The relay forwards packets it cannot read.

Signal path

The relay stores ciphertext. It reads nothing.

locate: signal path Your phone encrypts your location, sends ciphertext through a blind relay that cannot decrypt it, and your family's phone decrypts it. Plaintext never leaves your devices. ciphertext ciphertext your phone encrypts blind relay cannot decrypt family's phone decrypts plaintext never leaves this phone stores ciphertext, reads nothing keys exist only on your devices

what we store: ciphertext. what we can read: nothing.

The idea

Why this is proof two.

zero proved the principle where no server is needed. locate proves it where one is. The industry position says real-time location sharing requires a company that can see the locations. It does not. It requires a company that can move them. Encryption happens on your phone, decryption on your family's phones, and the keys never touch us. locate is designed so that if our relay were ever seized, subpoenaed, or sold, its contents would be the same to the new owner as they are to us: noise.
