0Tokens

About

0Tokens shows your Claude.ai usage at a glance, right in your browser toolbar.

It reads your current usage percentage from the Claude usage page and displays
it as a badge on the toolbar icon, so you always know how much of your limit is
left without opening a tab and checking manually.

Key features:
- Live usage badge on the toolbar icon
- Automatic background updates on a regular interval, so the badge stays current
- Optional notification when your usage reaches a threshold you set
- Lightweight, with a simple popup for details

Privacy first:
0Tokens runs entirely inside your browser. It reads only your usage percentage
from the Claude usage page and stores your settings locally. It does not collect,
transmit, sell, or share any data. There are no servers, no analytics, and no
tracking. Your conversations are never read, copied, or sent anywhere.

Permissions:
- Access to claude.ai: read the usage value shown on your usage page
- Tabs: refresh the usage page in the background to keep the badge current
- Storage: save your settings locally
- Alarms: schedule periodic background checks
- Notifications: alert you when usage reaches your threshold
