Privacy
Your message does not need to leave the device.
Signal Room is built so that the text you type and the audio you hear are produced locally. There is no account, no database of messages and no server-side conversion.
What stays in your browser
- The text you type and its Morse translation.
- Audio playback and WAV files, rendered with the Web Audio API.
- The speed, tone, volume and alphabet you select for the current tab.
What the server sees
Requests for the page and its static assets. The app does not send the message to the server. Cloudflare may process standard request metadata (such as the IP address and user agent) to deliver and protect the site, as any web host does.
Share links
A share link keeps the message in the URL fragment, the part after #. Browsers do not include that fragment in HTTP requests. Anyone who receives the complete link can read the message, so treat the link like the message itself.
Cookies and analytics
Signal Room does not set advertising cookies and does not run advertising trackers. The custom domain may use Cloudflare Web Analytics, a cookieless page-view counter provided by Cloudflare. It receives standard request metadata and the page URL, not the text you type, the Morse code or the audio. The site does not use a login, so there is nothing to profile. Cloudflare may also set its own security cookie when it needs to challenge automated traffic.
