Privacy Policy
Last updated: 10 November 2026
X Mass Media Downloader ("the extension") is published by NovaByteWorks, an independent developer based in India ("we"). In short: your X login never leaves your browser, nothing you download leaves your computer, and we keep only what we need to run the free tier and your licence.
Never sent to us
- Your X password, cookies or session. The extension reads X through the X tab you have open, by repeating the requests the X page itself makes, with the login already in your browser. What those requests carry stays in that tab.
- The photos and videos you download. They go straight from X's media servers to your Downloads folder.
- Which single posts you save. Saving one is not reported or counted.
- Which profiles or posts you only look at.
- Anything about your browsing outside X. The extension runs only on x.com.
- Your options and the record of what you have already downloaded. These stay in your browser, and removing the extension removes them.
What the extension sends us
Apart from fetching the free-tier settings, which carries nothing about you, the extension contacts our licence service only while you are signed in to X:
- A plan check when the panel opens on X: your X account id and handle, your licence key if you entered one, and the extension's version. It does not name the page you are on: the panel works out from the answer whether a download would be free. We answer it and write nothing down.
- When you press Download all media or Download bookmarks: the same details and the profile's handle (or that it is your bookmarks). These we keep, as below.
- Your licence key, with your X account id and handle, when you press Use key.
What we keep
- No analytics. To run the free plan and licences, our licence service keeps a record of the downloads you start (your account, the profile, the time and how many runs), and of refused attempts.
- Your X account id and handle, and the handles of profiles you download, with the time of each download, to count your free profiles and to link your licence to your account. When you download your own bookmarks, we see that too, to give the free plan its 20 most recent.
- Your licence key and purchase: the plan, the amount, the date and your email address, to deliver and support what you paid for. For purchases on Gumroad, also what Gumroad reports about the sale: the country of your IP address, the web page you came to the checkout from, and the affiliate whose link you used, if any, so we can see which of our pages and partners lead to sales and credit affiliates correctly.
- Feedback you send, with the email address you give (and your IP address, to stop spam).
We do not sell your data or use it for advertising.
Who handles it for us
Our licence service runs on Cloudflare, which stores this data for us. Like any web service, it sees the IP address a request comes from; we use it only to stop one address from flooding the service, and do not keep it with your account. Payments are processed by Gumroad under its own privacy policy. We never see your card or PayPal details.
Your rights
Email [email protected] at any time to see or delete what we hold about your X account. We keep your account and licence records until you ask; deleting them resets the free tier and removes the licence link.
Children
The extension is not directed at children under 13 and we do not knowingly collect data from them.
Changes
We will post changes to this page and update the date above.
