Privacy Policy

Last updated: 11 November 2026

TB Mass Media Downloader ("the extension") is published by NovaByteWorks, an independent developer based in India. Your Tumblr login stays in your browser, and the media you download stays on your computer.

Never sent to us

• Your password, cookies or login session.
• The photos, videos you download. They go from their source servers to your computer.
• Which single posts you save. Single-post saves are not reported or counted.
• Which blogs or posts you only look at, or your browsing history.

What the extension sends us

• A plan check: your Tumblr account id and handle, and your licence key if you use one. The check does not name the blog you are viewing. The service answers without recording that question.
• When you start a download: your account id and handle, your key if you use one, and the blog you chose, or that you chose your own likes.
• When you activate a key: your licence key with your account id and handle.

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 account id and handle, and the blogs you download, to count your three free blogs and link your key to your account. A real start from your likes identifies that list so the free tier can allow its 20 most recent posts.
• Your licence key and purchase: the plan, amount, date and email address, to deliver and support it. Gumroad also reports the sale’s IP country, referring page and affiliate, if any.
• 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 these records for us. Like any web service, it sees the IP address a request comes from. We use it to limit requests and do not keep it with your account. Payments use Razorpay or Gumroad, depending on the product and region, under their own Razorpay and Gumroad privacy policies. We never see your card or bank details.

Your rights

Email [email protected] to see or delete the records we hold about your Tumblr account. We keep 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 and contact

We will post changes here and update the date above. Contact NovaByteWorks at [email protected].
