Privacy policy
Last updated: 24 September 2026
In short
The videos you watch and the pages you visit stay on your computer. Our server only receives what it needs to count free downloads and manage paid licences, and a page's address only if you click “Report” yourself. We sell no data, we show no ads, and the extension contains no tracking of any kind.
The videos themselves never go through our servers: they travel straight from the site you are visiting to your computer.
Who is responsible
ExtNest Video Downloader is published by PyAudit Systems LLC, 30 N Gould St, STE R, Sheridan, WY 82801, USA.
For any question about your data: contact@extnest.com.
What stays on your device
This data is never sent to our server:
- the media found in your tabs, forgotten as soon as the tab navigates away or closes;
- your download history;
- your settings: language, theme, quality, file names, destination folder;
- the private key that signs your installation's requests.
Uninstalling the extension erases this data.
What our server receives
| Data | Why | Kept for |
|---|---|---|
| A random identifier for your installation, its public key and the extension version | Authenticate the extension's requests, which are all signed | As long as the installation is in use, or until you ask for its deletion |
| Your IP address, stored only as a fingerprint: a one-way computation with a secret key, the address itself is never kept | Enforce the free quota and limit abusive reinstallations | 90 days for downloads; the installation's one for as long as it exists |
For each authorised download: its kind (file, HLS, DASH) and the media server's name, e.g. cdn.example.com — never the page address, the video address, or its title |
Free quota, usage statistics, abuse prevention | 90 days |
| For customers: e-mail address, licence key fingerprint, plan, dates, activated devices, Stripe identifiers | Deliver and manage the licence, invoice, refund | The licence's lifetime, then 10 years for accounting records |
| Sign-in links sent by e-mail, with the address they were sent to | Sign you in without a password | Deleted one day after they expire; they are valid for 15 minutes |
| Administration log: licences granted and revoked | Security and evidence | 12 months |
| Only if you click “Report”: the page's address, the media's address without its parameters, its type and the error message, with your install's identifier | Understand and fix the sites where the extension fails | 90 days |
| Only if you answer on the page opened when you remove the extension: the reason you picked and the extension's version, with no identifier | Improve the extension | 12 months |
The database is backed up every day so it can be restored after an incident. Deleted data may remain in these backups for up to 12 months, until the oldest ones are erased automatically. Backups are used for restoring only.
Limited use of data (Chrome Web Store rules)
ExtNest Video Downloader's use of information received complies with the Chrome Web Store User Data Policy, including its Limited Use requirements:
- we use this data only to provide and improve the extension's user-facing features: finding media, authorising a download, managing licences;
- we do not sell or rent this data to anyone;
- we do not transfer it to third parties, except to the providers listed below who process it on our behalf, or where the law requires it;
- we do not use it for advertising, profiling, creditworthiness or lending purposes;
- no human reads this data, except with your consent, to answer a support request, for security reasons, or where the law requires it.
The permissions the extension asks for
| Permission | What it is for |
|---|---|
| Access to the sites you visit | Spot the video and audio played by the page, and save them. The analysis happens on your computer. |
tabs |
Read the title and address of the tab where a media is found, to name the file and show the media of the active tab. |
webRequest |
Read the type and size of the files the page loads, to spot video, audio and streams. No request is ever blocked or modified this way. |
webNavigation |
Forget a page's media when its tab moves to another page, including on sites that change their address without reloading. |
downloads |
Save the file into your Downloads folder. |
declarativeNetRequest |
Many media servers refuse requests without the page's Referer header. During a download, a temporary rule adds that header to the extension's own requests to that file's server only, and is removed afterwards. |
storage |
Keep your settings and the local history. |
contextMenus, sidePanel |
The right-click menu and the side panel. |
offscreen |
Assemble HLS and DASH streams, and convert audio, on your computer. |
| Scripts on a few social network and video websites | These sites describe their videos in their own data rather than in the page. A small script reads that data in the page to list the videos on screen, with their title and thumbnail, and hands them to the extension only. |
Legal bases (GDPR)
- Performance of the contract: paid licences, payments, e-mail sign-in.
- Legitimate interest: free quota, fraud and abuse prevention, security of the service.

Providers

- Resend — sending e-mails: licence keys and sign-in links.
- Railway — hosting of the server and the database, in Europe.
- Supabase — storage of the daily database backups, in Europe.
- Umami — audience measurement for the avd.extnest.com website only: page views, referrer, device type, with no cookie and nothing that identifies you. It does not cover the extension.
Our company is established in the United States, so the data we process may be accessed from the United States. Those transfers rely on the European Commission's standard contractual clauses.
Your rights
If you live in the European Economic Area, the United Kingdom or Switzerland, you may ask for access to your data, its correction, its erasure, the restriction of or objection to its processing, and its portability. Write to contact@extnest.com: we answer within 30 days. You may also complain to your country's data protection authority.
If you live in California, you may ask to know, correct or delete the personal information we hold, and you will not be treated differently for exercising those rights. We do not sell or share personal information, as those words are defined by California law.
Children
ExtNest Video Downloader is not aimed at children under 16, and we do not knowingly collect their data.
Security
Encrypted HTTPS traffic, cryptographically signed requests from the extension, licence keys and IP addresses kept as fingerprints, restricted database access.
Changes
We may change this policy. The update date is shown at the top of this page and, for any significant change, the extension or the website will tell you.
