Privacy Policy - Notebook Saver
Effective date: 2026-11-10
This policy covers the Chrome extension Notebook Saver ("the extension"). "We" means the extension's developer: the publisher shown under "Offered by" on the extension's Chrome Web Store page. Contact details are at the end.
In short
The extension has no servers, no accounts, no analytics and no ads. Nothing it reads is sent to us or to anyone else.
It reads the Gemini Notebook (NotebookLM) page in your browser only when you press one of its Save buttons, and only the notebook open in that tab.
The file it makes is built in your browser and saved by your browser. The extension stores nothing.
Where the extension runs
Only on notebook.google.com and notebooklm.google.com, plus its own pages: the toolbar popup, a welcome page (also its Options page) and a print page. It asks for no browser permissions beyond running on those two sites.
What it reads, and when
When you press Save and pick an item, it reads from the open notebook page, as the page shows it:
Chat: the questions and answers in the chat panel, and the titles of the sources each answer cites.
Open note: the title and text of the note open in Studio.
Sources list: the title and type of each source in the Sources panel, and its link when the panel shows one.
It does not read your other notebooks, your Google account details, your files' original content, or anything on other websites. It reads nothing until you press a Save button.
Saving
Markdown, Word and CSV files are built inside the page and handed to your browser as a download, like any file you download. Where it is saved is up to your browser.
PDF: the extension opens its own print-ready page in a new tab, with the document in it. That page receives the document once from the notebook tab, in memory, and the browser's Print saves it as PDF. If you do not open it within two minutes, the document is dropped from memory. PDF is not offered in Incognito windows.
What the extension keeps
Nothing. It has no storage permission and writes nothing to your device except the files you choose to download.
What we do not do
We do not collect, transmit, sell or share any data. The extension makes no network requests of its own.
No remote code: everything the extension runs is in its package.
It never changes your notebooks, sources or notes.
In Chrome Web Store terms
The extension handles "website content" (the text of the notebook page) on your device, only to perform its single purpose of saving that content as a file at your request. It is not transferred anywhere.
Limited Use
The use of information received by Notebook Saver adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements. The extension does not transfer this information to anyone, does not use it for advertising, and no person reads it.
How to stop it
Remove the extension from chrome://extensions. As it stores nothing, nothing is left behind except files you saved yourself.
Changes to this policy
If the extension's behavior changes, this policy is updated first, with a new effective date.
