How a message finds its way
You write
No 4G, no Wi‑Fi. The message is encrypted on your phone, then handed to the Droplet devices around you.
It hops from phone to phone
Every phone in range passes it on without being able to read it, a few dozen metres at a time.
It arrives
Dad gets it, even across the neighbourhood. The ticks tell you when he’s read it.
And when the internet is back
Droplet uses the internet too, or Tor to hide who talks to whom. You don’t pick anything: the best route is chosen for you.
Everything you expect from a messenger. Minus the network.
Voice messages you can replay
Record hands-free, pause, listen back before sending. Or film a round video.
Voice and video calls
As soon as you share a Wi‑Fi network, or one of you has internet.
Groups
Family, class, neighbourhood. Group messages hop from phone to phone too.
Disappearing messages
They delete themselves, and view-once photos open only once.
Locked chats
Hidden behind your fingerprint, invisible to anyone borrowing your phone.
In ten languages
English, French, Arabic, Hindi, Chinese, Spanish, Portuguese, Russian, German, Italian.
Nobody else reads your messages. Not even us.
A message only leaves your phone encrypted. The relays that carry it, and our server when it travels over the internet, only ever see a sealed envelope.
How Droplet protects your messagesMeet at 6 pm outside the station
What a relay sees
End-to-end encrypted
Only you and the person you’re talking to hold the keys.
A nickname is enough
No phone number, no address book uploaded.
Blind relays
They carry messages. They can’t read them.
For the moments the network gives up
During an outage
Reach your family when the cell towers are down.
In a crowd
Stadium, festival, market: find each other when the network is overloaded.
Far from everything
Hiking, villages, building sites: stay reachable with no coverage.
No data plan
Travelling or out of data, keep writing anyway.
Frequently asked questions
Do I need the internet to use Droplet?
No. Two phones in range talk directly, and every Droplet phone extends the range. The internet is used as well, when it’s there.
How far does a message go?
Each hop covers a few dozen metres, depending on walls and devices. The more Droplet phones around you, the further a message travels.
Can relays read my messages?
No. They carry an encrypted message only the recipient can open. They don’t even know what they’re carrying.
Is Droplet on iPhone?
Not yet: Droplet is available on Android. Keep it installed on your Android devices and it relays for everyone around.
