Privacy Policy

Last updated: 19 May 2026

This policy covers the Fame idm download manager (Windows desktop application) and the matata download helper browser extension that pairs with it. Both are developed by the same team and always function as a pair: the extension intercepts download URLs from your browser, the desktop application performs the actual transfer.

Plain-English summary

Fame idm and the matata extension do not collect, transmit, sell, or share any personal data. There is no analytics, no telemetry, no account, no login. The browser extension forwards download metadata (URL, filename, cookies for that origin) to the locally installed Fame idm application over a private operating-system pipe; nothing leaves your computer except the HTTP request your browser would have made anyway, performed by Fame idm with better resumption and segmentation.

1. Who we are

Fame idm is a free, open-source download manager. The extension and app are maintained by the Fame idm team. Contact: siagmoo26@gmail.com.

2. What data the extension processes

The matata download helper extension uses the following browser permissions. Each permission gives it access to a specific category of data and nothing else.

Permission	Data accessed	How it is used
`downloads`	URL, filename, MIME type, referrer of downloads you trigger	Hand the download off to the Fame idm desktop application via Native Messaging, and optionally cancel the browser's own copy so it is not duplicated.
`cookies`	Cookies for the origin of a download	Forwarded only to the local Fame idm application so authenticated downloads (logged-in pages, signed URLs) still succeed when Fame idm fetches the file itself.
`storage`	Your extension settings	Persist preferences (file extensions to intercept, minimum size threshold, output folder hint, clipboard-watch toggle) between browser sessions. Stored locally only.
`nativeMessaging`	—	Open a local stdio pipe to the Fame idm desktop application. This is the only way the extension communicates with the app. It does not involve the network.
`webRequest`	URLs of network requests in observation mode (Manifest V3)	Detect HLS (`.m3u8`) and DASH (`.mpd`) manifest URLs so the popup can list streams you might want to grab. The extension never modifies, blocks, or redirects any request.
`tabs`	Active-tab identity	Filter the sniffed-streams list shown in the popup to the tab you are currently viewing. No other tab data is read or stored.
`scripting`	YouTube / Vimeo player page DOM (read-only, scoped)	Run a small content script on YouTube and Vimeo only that reads the player's already-loaded format list (resolution / codec) so you can pick a quality from the popup. The script does not modify the page, does not log keystrokes or DOM, and does not contact any remote server.
`contextMenus`	—	Register a right-click menu item ("Download with Fame idm") that triggers the same handoff path.
`host_permissions: <all_urls>`	—	Required because downloads originate from arbitrary origins. The extension reads cookies and classifies download URLs from whichever site initiated the download. It does not read page content, DOM, or execute scripts in any page other than the YouTube / Vimeo cases listed above.

3. Where data goes

None of the data above is transmitted to any server operated by us or by any third party we contract.

Data leaves your machine in exactly two places:

The locally installed Fame idm desktop application, reached via Native Messaging — an operating-system-level stdio pipe between the browser and a process on your own computer. No network traffic.
The server hosting the file you are downloading. This is a normal HTTP request from your own machine, the same one your browser would have issued — just performed by Fame idm with multi-connection segmentation and resume support.

4. What the desktop application stores on disk

The files you downloaded, wherever you told it to save them.
A .mtpart sidecar next to each in-progress download (body bytes + resume metadata). Deleted automatically once the download completes.
Your preferences under the Windows registry key HKEY_CURRENT_USER\Software\matata\Gui (column widths, window placement, default output folder, bandwidth cap).
A plain-text queue-state file only if you explicitly opt in via --queue FILE on the command line.

5. What we never do

We never upload the list of URLs you download, the files themselves, your cookies, or anything derived from them.
We never run remote code, inject scripts from third-party servers, or load resources we do not bundle with the extension.
We never include analytics, advertising SDKs, fingerprinting, or crash-reporting that phones home.
We never sell, lease, or transfer user data to third parties.
We never use user data to determine creditworthiness or for lending purposes.
We never use or transfer user data for purposes unrelated to the single purpose of the extension (taking over downloads).
We never check for updates without your action. The desktop app checks for updates only when you explicitly run Fame idm → Check for updates or matata --check-update. That request reveals nothing beyond your IP and the current installed version — the same information any HTTP request would.

6. Children's privacy

Fame idm and the matata extension are not directed at children under 13. We do not knowingly collect any data from any user. If you believe we hold data about a child, please contact us and we will delete it on confirmation.

7. Your rights

Because we hold no personal data on our servers, there is nothing to access, correct, port, or erase from our side. All data the extension and app handle is on your own device; uninstalling the extension and removing the registry key under HKCU\Software\matata erases the local state.

8. Open-source verification

The extension and the desktop application are open source. You can audit every line at the project's source repository and confirm that no network endpoint is contacted other than the file servers your downloads target. The build is reproducible: build.bat produces exactly the binaries shipped in the released installer.

9. Changes to this policy

If this policy changes, the Last updated date at the top of the page will change with it. The canonical version is always the one served at https://fame.proxaslab.com/privacy. Material changes that expand what data is collected or where it is sent will be announced in the release notes shipped with the affected version.
