Privacy Policy
Last updated: August 24, 2026
Mochi Cat ("the Extension") is developed as a privacy-first, zero-telemetry browser extension. Your privacy is not a setting; it is the core architectural principle of this software.
1. Zero Data Collection
- No Personal Data: Mochi does not collect, transmit, store, or sell any personally identifiable information (such as your name, email, IP address, or location).
- No Browsing Activity Tracking: Mochi does not track, log, or transmit URLs, page contents, reading habits, keystrokes, or mouse movements.
- No Analytics or Telemetry: Mochi contains no third-party tracking scripts, analytics SDKs, advertising libraries, or telemetry beacons.
- Zero Outbound Network Requests: The extension makes zero network requests. It operates 100% offline. All sprites, scripts, and localization catalogues are bundled directly within the extension package.
2. Data Storage on Your Device
Mochi uses chrome.storage.local exclusively to store your preferences on
your local machine:
- The name you chose for your cat
- Your selected coat / breed
- The liveliness (energy) preference
- Your language preference (Turkish, English, or Automatic)
- A list of hostnames you have explicitly muted or allowed
- A timestamp for the Snooze timer
- Whether the cat is switched on at all, which is what the toolbar's master switch and the keyboard shortcut both write
- Whether you have finished the one-time welcome introduction, so that it is never shown to you twice
That list is exhaustive: it is every field the extension writes. Google's User Data policy counts data as "handled" even when it never leaves the machine, so an incomplete list here would be a false statement rather than a tidy one.
None of this information ever leaves your device. It is stored in
storage.local, not storage.sync — it is not synced across
Google accounts or sent to any remote server.
3. Permissions Justification
Mochi requests the minimum permissions required to function:
| Permission | Purpose |
|---|---|
storage |
To save your cat's name, coat, energy, and site preferences locally on your computer. |
activeTab |
To read the hostname of the page you are looking at, so the popup's "show on this site" switch knows which site it is toggling. Granted only at the moment you click the toolbar icon; nothing runs in the background because of it. |
Content script accesshttp://*/*, https://*/* |
Not a host permission — host_permissions is empty. The content
script's own match pattern is what lets it detect text line bounding boxes and
render the cat on the pages you browse, because the cat has to live on the page you
are reading. It never transmits page data. |
4. Children's Privacy
Mochi does not collect information from anyone, including children under the age of 13.
