Gart app

Replace worries
with a button
and a plan.

Hold the button. Your alert, your location and your response protocol reach your Responders in seconds. They act on your plan.

Free. Android today. iPhone version in development.

Core features

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.

Setup

Add your Responders, write the plan, run a test.

01

Add your Responders

Your Responders are the people you trust: family, a partner, your team. They need the app too. Why?

Every day

Check in on ordinary days, alert when you need help.

01 · soon

The check-in

One tap tells your family, your partner or your co-founder you are fine.

Privacy

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 →
Backup

A new phone picks up where the old one left off.

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.

People who reject corporate surveillance and want tools that respect their sovereignty.

Only your Responders can read it. They hold the decryption key.

Questions

Before you install.

Is Gart available for iPhone?
Not yet. Gart runs on Android phones today; the iPhone version is in development. Apple users can contact us to be notified the moment it launches.
Will this work outside my country?
Yes. There are no geographic restrictions or data residency requirements.
What if I have no internet connection?
Then the app does not work. You need to be online to send an alert.
Do my Responders need the app?
Yes. App to app is more private than SMS or other channels. Holding one button is also faster than opening a chat app, dialing a number or typing a message, and in an emergency you want what is quickest to hand. And because you and your Responders use the same local, encrypted app, you can release sensitive documents, such as your response protocol, to them only at the moment they need them.
Can anyone access my Gart app data?
No. Everything you set up or discuss in the app is encrypted.
What about false alarms?
Learn how the button works before you need it: Gart has a Test alert. If you trigger an alert by accident, your Responders follow your response protocol and can quickly check whether you are under duress or pressed the button by mistake.
Do you store or sell my private data?
No. You do not need an email address, phone number or name to set up Gart. If you sign up to our occasional newsletter, we store your email address for that purpose only. Use an email you check regularly, but not your primary one.
Install

Get the app.

Gart is on Zapstore, an app store that needs no account.
Install Zapstore, then Gart.
