In-chat apps

From the Delta Chat FAQ.

In-chat apps

You can send apps to a chat - games, editors, polls and other tools. This makes Delta Chat a truly extensible messenger.

Where can I get in-chat apps?

• In a chat, using Attachment Button → Apps

• You can also create your own app and attach it using Attachment Button → File

How private are in-chat apps?

• In-chat apps can not send data to the Internet, or download anything.

• An in-chat app can only exchange data within a chat, with its copies on the devices of your chat partners. Other than that, it’s completely isolated from the Internet.

• The privacy an in-chat app offers is the privacy of your chat - as long as you trust the people you chat with, you can trust the in-chat app as well.

• This also means: Just like for web links, do not open apps from untrusted contacts.

How can I create my own in-chat apps?

• In-chat apps are zip files with .xdc extension containing html, css, and javascript code.

• You can extend the Hello World example app to get started.

• All else you need to know is written in the Webxdc documentation.

• If you have question, you can ask others with experience in the Delta Chat Forum.
