The short version: Racna collects nothing and sends nothing. Everything it captures stays inside your browser. There is no server behind this extension.
Racna is a browser extension that watches a page for errors and failed requests, on sites where you choose to enable it. This page explains what Racna touches, where that data lives, and why the answer to "what gets sent anywhere" is: nothing.
On pages where you have enabled it, Racna captures:
fetch or XMLHttpRequest
Racna is off by default everywhere except localhost and 127.0.0.1.
On any site you have not switched on, it keeps nothing, shows nothing, and sends nothing;
you enable it per site to start capturing.
Nothing. Captured events live in the memory of the tab they were captured in. They are not written to disk, do not survive closing the tab or restarting the browser, and are never transmitted anywhere. Racna sends no telemetry, no analytics, no crash reports, and shows no ads. It loads no third-party or remote code at runtime and has zero runtime dependencies.
Your settings are the only thing Racna persists: ignore rules, watch rules, the list of
sites you enabled, and panel preferences. These are saved through
chrome.storage.sync, the browser's own extension storage. If you are signed
into the browser, Google (or Microsoft, on Edge) syncs that storage across your own devices,
the same way it syncs your bookmarks. That data stays within your browser account. It never
reaches any server operated by Racna or its author, because no such server exists.
Racna's copy and export feature has a toggle labelled "AI". Despite the name, it is a
formatting feature and nothing more: it arranges a captured entry into a structured Markdown
block that you can paste into an AI tool yourself, if you want to. Racna does not connect to
any AI service, does not send captured data to one, and has no network access of its own.
Separately, the "Hide sensitive headers" setting (on by default) masks credential headers
such as Authorization and Cookie in all copied and exported text,
whichever format you use. Request and response bodies, and full URLs (which can carry tokens
in their query string or fragment), are not scanned or redacted, so review what you copy
before sharing it.
storage is the only permission in the manifest. It is what saves your rules
and settings, as described above.
<all_urls> so that the per-site
toggle can work on any site you choose. The scripts load on pages broadly, but until you
enable Racna for a site it keeps and shows nothing from that site, and it sends nothing
anywhere on any site. No host permission grants Racna data access beyond the page you
turned it on for.
web_accessible_resources exposes only the extension's icon images, so the
overlay can display them.
Racna includes no analytics SDKs, no error-reporting services, no advertising, and no tracking of any kind. These pages and the extension set no cookies, so there is nothing for a cookie banner to disclose. The source code is public, so all of the above can be checked rather than taken on trust: github.com/Niki-Mozzon/racna.
If a future version of Racna changes what it stores or observes, this page will be updated before that version ships, and the date at the top will change. The history of this page is visible in the repository.
