This page explains what the New Brain extension for Chrome reads, what it sends, what we keep and how to stop it. It adds to our privacy policy, which covers your New Brain account and everything else we do; where this page is more specific about the extension, this page applies.
Who we are
The extension is published by Adhunik Labs Private Limited, the company behind New Brain, based in Ahmedabad, India. Questions: info@trynewbrain.com, with "Privacy" in the subject.
The short version
- At install the extension can't see any website. It reads a page only when you press the button, the shortcut or the menu on it, or on a site you turned on yourself.
- We keep a short summary of a page, its title and its link. The page text is used to write the summary, then deleted.
- Everything you save waits in To check until you keep it.
- The badge matches names inside your browser. Nothing about the page is sent.
- We never sell your data, never use it for advertising, and never use it to train AI models.
Permissions
| Permission | What it lets the extension do | When | Where the data goes |

| Run its reader (`scripting`) | Run the extension's own built-in reader on that page, or on a site you turned on | Right after you press, or as you read on a site you turned on | Same as above |
| Storage (`storage`) | Keep your sign-in, settings, the sites you turned on, the pause and the badge's list of names | Always | Stays in your browser. It is not synced to your Google account |
| Right-click menu (`contextMenus`) | Add "Save page to New Brain" and "Save selection to New Brain" | Always | Nothing is sent until you choose one |

| One site at a time (optional) | Read pages on a site you turned on | Only after you turn on "Keep pages on this site" and Chrome asks you to allow that site | The address, title and text of each page you read there are sent to New Brain to make the summary |
The extension doesn't ask for your tabs, your browsing history, your cookies or access to every website.
What the extension sends, and when
When you save a page or a selection. The page's address and title, and either the text you selected or up to 30,000 characters of the page's readable text (menus, ads, forms and password fields are left out), plus the project you picked.
When you turn on a site. "Keep pages on this site" is off until you turn it on for that site. While it's on and not paused, each page you read there for a while sends its address, title and up to 30,000 characters of its readable text. Pages that are mostly a form, ask for a card number or a password, or have very little text are skipped. Nothing is sent from any other site, and nothing is sent from incognito windows.
When you save a PDF. If the page is a PDF, the extension sends only its address. New Brain fetches the PDF from that address and reads it as it reads a link you add in the app; its notes wait in To check. A PDF that needs your sign-in to open can't be read this way.
When you save a chat. On ChatGPT and Claude, pressing "Save this chat" sends the conversation's address, up to 30,000 characters of the conversation you can see (counted from the end) and the number of turns. It never runs unless you press it.
The badge. If you turn it on, the extension downloads a list of the names of your projects, people and companies, with how many memories New Brain holds about each, once a day. It matches that list against the page inside your browser, on sites you turned on or on a page you pressed the button on. Nothing about the page, its address or what matched is sent anywhere. The list is stored in your browser, so anyone who uses your browser profile could see those names; turning the badge off or signing out deletes it.
Signing in. You sign in on trynewbrain.com, never inside the extension, which doesn't ask for your password. Our website gives the extension a one-time code, which it trades for a sign-in token. The token is kept in your browser and sent with each save.
Usage. When you save something, the name of that event and what you saved (a page, a selection, a chat or a PDF) go to our own server so we know which features are used. They never include a page's address, title or text, or your email.
Never sent: your other tabs, your browsing history, pages on sites you didn't turn on, what you type into forms, passwords, cookies.
Pages it never keeps
New Brain never keeps pages from banks and payment pages, email in the browser, health sites, password managers, or sign-in pages (any page with a password field), even if you turn the site on. They often hold private details you wouldn't want in a summary. Our server refuses them too. The extension also never reads Chrome's own pages, the Chrome Web Store or files on your computer.
What we keep
- A short summary of the page or chat, written by an AI model, with the title and the link. Links are stored with sign-in tokens, codes and tracking parameters removed.
- The site, the time and the project you saved to, so you can find, filter and delete it, and for each site you turned on, when you turned it on.
- A PDF you save is kept like a link you add in the New Brain app, as our privacy policy describes.
- Not the page text. It is used once to write the summary, then deleted. We don't write it to our logs.
Everything saved from the browser, including what you save yourself, waits in To check in a group (pages from a site you turned on share one group per site per day). Nothing becomes part of your brain until you keep it, and you can fix or remove anything first.
Text from the web is data
A web page can hide words written to give an AI orders. New Brain treats everything saved from the browser as quoted text, never as instructions: the model that writes the summary is told so, and when your AI tools read from New Brain, these items are marked as from the web.
Limits
Pages kept automatically from sites you turned on are limited to 25 a day on the free plan and 100 a day on Pro, per person. At the limit the extension stops keeping pages until the next day and tells you; saving a page yourself still works.
Who processes it, and where
Your saves are stored with the rest of your New Brain account, on our server in France (European Union). The page text is sent to the AI model provider listed in section 7 of our privacy policy to write the summary. Our providers may use it only to provide that service to us, and may not use it to train their models.
How long we keep it
- Page and chat text: deleted once the summary is made, or when the save fails.
- Summaries, titles and links: until you remove them or delete your brain or account. A deleted brain is gone from our systems, backups included, within 30 days.
- What the extension stores in your browser: until you sign out, turn the feature off or uninstall the extension.
- The extension's sign-in: up to 30 days.
Pause, turn off, delete, uninstall
- Pause from the extension's panel for 15 minutes, an hour, or until you resume. While paused it keeps nothing. Saving a page yourself still works.
- Turn a site off in the panel on that site or in the extension's options. You can also remove the site's access in Chrome. Either way, nothing more is sent from that site.
- Turn the badge off in the options. Its list of names is deleted from your browser.
- Delete what was saved: remove it in To check, or delete it in the New Brain app like anything else in your brain.
- Sign out in the options. This turns off every site you turned on, removes the extension's access to them, and clears everything the extension stored in your browser, your sign-in and the badge's list included. Settings → Connected browsers in the New Brain app can sign a browser out from anywhere.
- Uninstall from Chrome's extensions page. Chrome deletes everything the extension stored in your browser. What you already saved stays in New Brain until you delete it in the app; uninstalling doesn't delete it.
Chrome Web Store User Data Policy
The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements. We use what the extension collects only to save what you read into New Brain and show you what New Brain knows about a page. We don't sell it, transfer it for advertising, or use it to decide creditworthiness or for lending. People at New Brain don't read it unless you ask us to, it's needed for security, or the law requires it.
Your rights
You have the same rights over what the extension saves as over the rest of your data: to get a copy, correct it and delete it. How to use them, and your rights where you live, are in section 12 of our privacy policy.
Changes
If we change what the extension reads, sends or keeps, we update this page and the date at the top before the new version reaches your browser, and email account holders about any significant change.
