Marlowea cat who writes a novel out of your typing
Privacy
The short version is the whole version.
Last updated 26 July 2026
Marlowe counts that you typed. He never records what you typed.
Nothing leaves your computer. There is no server, no account, no analytics, and no network request of any kind.
What it reads
Marlowe adds a keyboard listener to the pages you visit. For every key press it does
exactly one thing: it adds 1 to a counter.
It does not read which key was pressed. It does not read the contents of any field, page, form, or document. The character is discarded inside the event handler and is never stored, compared, buffered, or transmitted. Key presses inside password fields are not counted at all.
What it stores
Everything Marlowe knows is kept in chrome.storage.local on your own
computer:
- a running count of key presses, and the word total derived from it
- the title, genre and chapter number of the imaginary book in progress
- the list of imaginary books already finished
- imaginary letters from imaginary readers
- your settings: where the cat sits, which sites you have hidden him on, your movement preference, and whether he is switched on
- a list of calendar dates on which you wrote at least one word, used to show a streak
No page URLs, page titles, page contents, form contents, or typed characters are stored.
What it sends
Nothing. Marlowe makes no network requests and has no backend. All artwork, code and data ship inside the extension package and stay on your machine.
Permissions, and why each exists
-
storage— to keep the counts and settings above on your own computer. -
activeTab— when you click the Marlowe toolbar icon, the popup reads the current tab's hostname so it can offer "hide him on this site". The hostname is used only for that comparison, and stored only if you turn the option on. - Access to the sites you visit — the cat has to be drawn on the page you are looking at, and the key counter has to run wherever your keyboard focus is. Used for those two things only.
Data sharing and sale
There is none. No data is collected, so there is nothing to share, sell, or transfer, and no third party has access to anything.
Your copy, and deleting it
The Study has a Keeping it section that saves everything to a JSON file you own, and restores from one. Keep a copy: removing the extension from Chrome deletes its storage along with it, and nothing syncs between machines.
Children
Marlowe is suitable for all ages and does not collect personal information from anyone, including children.
Changes
Any update to this policy is published at this same address with a new date above. A change to what the extension reads or stores would ship as a new version with its own review.
