For businesses

A chat box for your website that only you can read

Customers write to you without an account. Their messages arrive in the Sika app on your phone, like any other chat.

Add it in three steps

In the Sika app, open Business, then Website chat. Choose the name customers see, a welcome line, a colour, and the websites that may show your chat box. Save.
Copy the line the app shows you and paste it into your website just before the closing body tag. It looks like this:
```
<script src="https://sikaos.app/chat/widget.js" data-key="YOUR SIKA KEY" async></script>
```
Open your website. A chat button appears. Write a message from another device and answer it from your phone.

No website? The app also gives you a chat page at sikaos.app/c/your-shop-name. Share it, or put it in your social media profile.

Only you can read it. Each message is sealed in the visitor's browser to your key. Our servers and the relay carry sealed mail they cannot open.
Light. The button is about 2 KB. The chat itself loads only when a visitor opens it.
Your websites only. The chat box can be shown only on the websites you list. The browser refuses everywhere else.
Your language. The chat window speaks the visitor's language, in the same 18 languages as the app.
Works with weak signal. A message typed while offline waits and goes out when the visitor is back online.

Your phone listens through a relay, so turn the relay on in Settings first. The app tells you if it is off.
This is an early version. Visitors can send you text and files up to 1 MB (a photo, a receipt, a PDF). The file reaches your phone while the visitor keeps the chat open, and the app checks it before showing it. Visitors can also record a voice note of up to 30 seconds; the browser asks them for the microphone first and nothing is recorded until they tap.
The staff inbox. Your team can also answer from a browser. In the Sika app, link a browser at sikaos.app/inbox with a code, and every chat box conversation appears there too. You can give a chat to a teammate, keep private notes the visitor never sees, use quick replies, send and receive files and voice notes, and turn on browser notifications. Each linked browser holds its own key, so what is sealed to you stays sealed. A free account can link one other device and Sika Business Pro up to four.
Options for the button: data-lang="yo" picks a language, data-position="left" moves it to the left, and data-open="true" opens the chat when the page loads. SikaChat.open() and SikaChat.close() work from your own buttons.
What we keep and what we do not is in the Privacy Policy and on the Security page.
