Privacy Policy

Last updated: 4 November 2026.
Contact: support@subnook.com

Subnook is a desktop app from Carnivore Clan Ltd (the company that owns Subnook). This policy explains how we access, use, store, and share information.

Most of your Subnook data stays on your computer. If you complete Account setup in the app, we also store your first name and email on our systems so we can write to you. Videos play through YouTube’s official embedded player; see Google’s privacy policy and the YouTube Terms of Service for how YouTube handles playback.

Using Subnook means you agree to this policy.

Who we are

Carnivore Clan Ltd operates Subnook and this website (subnook.com). Privacy questions or complaints: support@subnook.com.

What Subnook is

Subnook is a local-first inbox for YouTube channels you already subscribe to. Playback uses the official YouTube player. We do not download video files.

YouTube data we access

Subnook does not use your YouTube login. New uploads are read from public YouTube channel feeds (and our shared cache of those feeds). That is public channel data, not a copy of your private YouTube watch history.

Playback and thumbnails go through YouTube. Our feed cache may use YouTube’s public Data API on our servers (not your login) to check whether a video can play in the official player.

What we store on your device

The app keeps this on the computer where you installed Subnook:

Channel list and video metadata (titles, dates, thumbnails, channel IDs)
Videos you save inside Subnook
Channels you mark as favorites inside Subnook
Channels you mute inside Subnook
App settings, including your first name and email if you set up an account
A backup file only if you export one

This lives in your app data folder, not in a Subnook “account” on our website. Uninstalling the app removes it from that computer.

What we store on our systems

We do not upload your full channel list or watch history to Subnook servers as a profile of you.

To keep the inbox fresh, the app may send YouTube channel IDs (public IDs of channels in your Library, or Popular people) to our feed cache. That cache is a shared list of channels, not a profile of you. It stores public upload metadata for those channels so every Subnook user does not have to fetch the same feeds alone.

We do not sell that list. We do not use it to build an advertising profile. We do not join it to your email on the server.

If you tap Next on Account setup, we store your first name and email so we can write you notes about Subnook and ask for feedback. We do not create a login. We do not join that email to your channel list.

If a video fails to play in the official player, the app may send that public video ID and the player error code to the same cache so we can ask YouTube whether it is gone, embed-off, or blocked in some countries. No email, no account id, no device id. We store YouTube’s answer for at most 30 days.

If you write to us, we also keep:

Support messages (email and the website form, delivered to us by Formspree)
An error report only if you send Feedback in the app with Include error logs ticked (app version, page, recent error lines, public video or channel IDs).
Payment records when you buy on subnook.com (Stripe: name, email, and payment status as Stripe provides them)

How we use this information

We use it only to:

Show your subscription inbox and play videos in the official player
Refresh public upload lists for channels in the shared cache
Skip videos that cannot play in the app
Write you notes and ask for feedback if you set up an account
Answer support mail and process payments on subnook.com
Meet the law if we must

We do not sell your data. We do not use it for advertising.

Sharing

We share information only as follows:

YouTube — when you play a video, the official embedded player and thumbnails are served by YouTube under their terms: Google Privacy Policy, YouTube Terms.
Our hosting — the website and the feed cache run on our hosting providers. They process data on our instructions only.
Formspree — if you use the website support form, the message is passed to our inbox.
Stripe — when you pay on subnook.com, Stripe processes the payment.
Wise — if we pay you a friend reward, we send the name, email, and transfer details you gave us.
The law — if we are required to disclose something by a valid legal demand.

We do not let third parties serve ads in Subnook. We do not sell your information to data brokers.

Cookies and similar technology

The Subnook desktop app is not a website. It stores data in files on your computer as described above, not as browser advertising cookies.

This website is a simple marketing site. We do not run an advertising pixel. If you submit the support form, Formspree may set cookies needed to run that form. Stripe may set cookies on the pay page. If you open a Subnook link with a friend code (?ref=), we store that code in your browser until you click a different friend’s link or clear this site’s data, so a later purchase here can credit them. We do not cut that off after a few weeks. Not ads. Your browser can block cookies; the desktop app will still work, and we will not remember the code.

How long we keep it

On your device: until you delete Subnook data or uninstall.
Channel IDs in the shared cache: for as long as the channel is useful to the cache. They are public IDs, not your name.
Playability answers (public video ID plus YouTube’s embed/geo flags): at most 30 days, then we delete or refresh them.
First name and email from Account setup: until you ask us to delete them.
Support mail: as long as needed to help you and keep a basic record.
Payments: as long as tax and accounting rules require.
Billing identity, friend codes, sale blocks, and payout details: we keep these even if you cancel. We hide the referral screen in the app if you are no longer a paying subscriber. We keep our copy for tax, fraud, and history. Email support@subnook.com if you want to know what we hold.

Your choices

Export / import a backup from Account if you want a copy or a move to another computer.
Delete Subnook data on Account, or uninstall to remove the local database from that computer.
Email support@subnook.com to delete your name and email from our list.

If you are in the UK or EU you can also ask us what we hold about you, ask us to correct it, or ask us to delete your name, email, support, or payment records we control. Email support@subnook.com. Data that only exists on your computer is yours to delete by uninstalling or clearing app data.

Children

Subnook is not directed at children under 13.

Security

This website is served over HTTPS. No method is perfect. Do not install Subnook on a computer you do not trust.

Changes

We will change the date at the top when this policy changes. Material changes will be shown on the site or in the app.
