About Signalline
Signalline is a lightweight messaging app built to run on very little data. It has three parts: a search index, real-time chats, and a local updates feed. Chats and updates only open once you're signed in.
Search
The home page. Scans every page here plus the local updates feed, and your own chats when you're logged in.
Chats
Direct messages in real time. Photos and videos sent in a chat are permanently deleted 3 hours after they're sent.
Updates
A local feed of what's changed in the app. Requires an account.
Create an account
Sign up with a username, email, and password. You'll land back on whichever page sent you here.
Data & privacy
Messages are sent over a single persistent connection instead of repeated polling, and static assets are cached locally, to keep ongoing data use as close to zero as the network allows. Media sent in a direct message is removed from the server automatically 3 hours after it arrives — no action is needed from either person in the conversation.
