Window Cat — Privacy Policy

Last updated: 23 September 2026

Window Cat collects nothing and sends nothing anywhere.

That is the whole policy. The rest of this page explains what that means in practice, and every claim in it is one you can check for yourself from your own browser, without taking our word for anything.

What we collect

Nothing. There is no account, no identifier, no profile and no telemetry.

What we send

Nothing. The extension makes no network requests of any kind. Every cat is drawn in code as SVG, every sound is synthesised in code with the Web Audio API, and there are no images, fonts, audio files, analytics scripts or third-party libraries loaded from anywhere. You can confirm this yourself: open DevTools, go to the Network tab, and use the extension for as long as you like.

What we store, and where

Two things, both on your own computer:

• Your settings — which cat you chose, how many cats you keep, how often you want visits, quiet hours, blocked sites, size, colours, sound. These use Chrome's storage.sync, so they follow your own Chrome profile if you have Chrome sync switched on. That is between you and Google; it never passes through us.
• A record of the extension's own activity — how many visits you have had, how many times you have fed the cats, when the last visit and the last treat happened, and the times of visits in the past hour, which is how the hourly limit is enforced. These use storage.local and never leave the device.

Neither includes anything about which sites you visit, or anything about you.

Page access

The extension asks for access to the pages you visit so it can draw a cat on top of them. It uses that access for exactly two things: adding its own element to the page, and reading the size of the window to decide where the cat should stand.

It does not read the text of pages, does not touch form fields, does not look at what you type, and does not record which sites you visit.

One clarification, because it sounds worse than it is: while a page is open, the extension keeps a single number in memory — the time you last pressed a key. Not which key, not how many, just a timestamp. It exists so a cat never interrupts you mid-sentence. It is never written to storage, never leaves the page, and is discarded the moment the tab closes.

Data sharing and sale

There is no data, so there is nothing to share or sell. We do not, and could not.

Children

The extension collects no data from anyone, of any age.

Changes

If this ever changes, the change will appear here and in the extension's listing before it ships. The commitment above is a design constraint, not a preference: the code has no network permission at all, so sending data would require a new permission that you would have to approve.

Where this is published

This policy is served at https://window-cat.pages.dev/privacy-policy.html and is generated from the copy in the extension's own source tree, so the two cannot disagree.
