Your phoneA Responder's phone
From plan to calm response.
Check in every day Soon
Let your Responders know you are OK, wherever you are. One tap on the check-in widget or the beige button on the home screen sends it.
Alert privately and reliably
Your alert leaves your phone encrypted and travels over several independent relay servers. Delivery does not depend on our servers being up.
Respond with a plan
For each group, write your own response protocol: who gets alerted, and with what instructions. Set it up in advance, so everyone knows what to do.

Add your Responders, write the plan, run a test.
Add your Responders
Your Responders are the people you trust: family, a partner, your team. They need the app too. Why?
Write the response protocol
Who acts first, what they do, whom they call, what they look for. Written in calm, followed in a crisis. Get help writing your response protocols.
Test alert
In the group details, hold the test alert button. Your Responders get a notification marked as a test, with the location fixed on Mount Everest. Run one with every Responder before you rely on a live alert.

Check in on ordinary days, alert when you need help.
The check-in
One tap tells your family, your partner or your co-founder you are fine.
Trigger alert
Hold the button on the home screen until its rings turn yellow. Your alert goes to your Responders peer to peer, encrypted, over a relay network we cannot read.
Your group gets alerted
The Responder who taps “I'm handling this” opens your response protocol. Until then it stays hidden.

No email or phone number to sign up, and no persistent tracking.
No live location
Gart has no location monitoring, so we cannot follow your movements. Your location leaves your phone only with an alert or a check-in, directly to your Responders and fully encrypted.
What is Gart →No personal data
No phone number, name or email to sign up. Your account is a cryptographic key pair, created on your phone in one tap: the public key identifies your Gart account, the private key is yours to keep safe and log in with.
Your identity →End-to-end encrypted
Alerts, chat messages and group setup are encrypted before they leave your phone and decrypted only by your Responders. We cannot read them.
Privacy →No email or phone number to sign up, and no persistent tracking.

Gart backs up your app data, such as groups and settings, on its own: encrypted on your phone, then stored on Gart's backup server. That is the one server Gart runs; alerts and chat messages go over independent relays. The one thing you keep safe yourself is your login key. If you log in with a remote signer, the signer holds the key and there is nothing to back up from Gart.
