IG Mass Media Downloader ("the extension") is published by NovaByteWorks, an independent developer based in India ("we"). This policy explains what the extension does with data, in plain words.
The extension runs inside your browser and makes requests to instagram.com using the login session already in your browser, in the same way the Instagram website does. Your Instagram cookies, password and session never leave your browser and are never sent to us.
| Data | Why | Kept |
|---|---|---|
| The numeric user id and username of the Instagram account logged in to your browser | to count the three free profile downloads and to check whether a licence applies | as long as the account uses the extension, then 24 months |
| The username of each profile you download | to count distinct free profiles; repeat downloads of the same profile are not counted again | same |
| Your licence key and the plan it belongs to, when you enter one | to unlock the paid plan on your Instagram account | for the life of the licence |
| The extension version and the time of each request | operations and abuse prevention | 90 days |
We do not receive the media you download, your Instagram cookies, your browsing history, or anything about profiles you merely view.
The downloaded files, your options, the list of files already downloaded per profile, and the total size downloaded are stored by the extension in your browser and in your Downloads folder. Removing the extension removes its browser storage; the files stay.
Purchases are processed by Lemon Squeezy, LLC, acting as merchant of record. Lemon Squeezy collects your email address and payment details under its own privacy policy; we receive your email address, the plan purchased and the licence key.
Our licensing service runs on Cloudflare Workers and stores the data above in a Cloudflare D1 database. Cloudflare processes it on our behalf.
You can ask us to show or delete the data we hold about your Instagram account at any time by emailing novabyteworks@gmail.com. Deleting it resets the free tier and removes any licence binding.
The extension is not directed at children under 13 and we do not knowingly collect data from them.
We will post changes to this page and update the date above.
