Support policy

Let’s get the record straight: unless you are using our paid services, we don’t owe you anything. The software is provided as is, with no warranty and no guarantee to work with all ill-configured servers/networks on every device with non-stock Android crippled by phone manufacturers.

We do, however, have great sympathy for any decent person who requires support, and we do try to help. You just have to ask nicely. If you are rude, make demands, feel entitled to premium service or lecture us how to behave, we kindly ask you to uninstall our app and be gone for good. We won’t be saddened by 1-star review and we’ll likely leave a sarcastic reply.

Getting support

☆ Read F.A.Q. on our website, https://xabber.com/faq/
You’ll be amazed how many issues are already covered!

☆ Email [email protected]
This is the best way to get tech support. Be nice, and we’ll do our best to provide you help. Please, describe your issue in detail. If possible, attach screenshots and debug logs that would help us understand what went wrong.
☆ Please, DON’T ask for support in Google Play reviews!
Reviews are by far the worst way to reach out to us for tech support. XMPP is a federated protocol, which means the network consists of thousands of servers with different settings, and that there are multiple points of failure. We can’t conceivably know what went wrong from a short message, our replies are limited to 350 characters and the medium does not support back and forth exchange of information.
