The relay

The relay is our server. It exists for one reason: to hold a sealed message until the phone it is for comes to collect it.

What it does

• A sender deposits a sealed envelope under a token that only the two paired phones can compute. The token changes over time.
• The recipient's phone asks, on its own schedule, whether anything waits under its tokens, and takes it.
• Envelopes are deleted when collected, or when they expire.

What it learns

• That some phone deposited an envelope of a certain size at a certain time, and that some phone collected it.
• The network address of whoever connected, for as long as the connection lasts.

What it never sees

• Who you are, who you are talking to, or what you said. There are no accounts. Nothing on the relay links a token to a person, a number, or another token.
• Your contacts, your number, your name, or your card.
• Whether a number "is on Channel". A request left at a number is accepted whether or not anyone will ever collect it, so the answer is always the same.

Choosing not to use it

Settings › Reach › Internet mailbox turns the relay off for a profile. Messages then travel only when the phones are near each other, or by way of a phone carrying for you.

English is the reference text; any translation is a convenience. Help is stored on this phone and never contacts anyone.
