API Rate Limiter - Privacy Policy

Last updated: March 28, 2026

Overview

API Rate Limiter is a Chrome extension that simulates API rate limiting by intercepting fetch and XMLHttpRequest calls and returning configurable error responses. Your privacy is important, and this extension is designed to keep all data local to your browser.

Data Collection

API Rate Limiter does not collect, store, transmit, or share any data externally. Specifically:

• No personal information is collected.
• No browsing history is recorded.
• No request URLs or data leave your browser.
• No analytics or tracking scripts are used.
• No cookies are set by the extension.
• No data is sent to external servers.

How It Works

API Rate Limiter uses a content script to intercept fetch() and XMLHttpRequest calls on web pages. When a request matches a user-defined URL pattern and the rate limit is exceeded, the extension returns a simulated error response instead of making the actual network request. Rate-limit rules, request counts, and a request log are stored temporarily in chrome.storage.local on your device. Log data is pruned to the most recent 500 entries.

Permissions

The extension requests the following permissions:

• storage — Used for storing rate-limit rules, request counts, and the request log locally on your device.
• activeTab — Required for the popup to identify the currently active tab and display relevant request data.

Third-Party Services

API Rate Limiter does not use any third-party services, APIs, or SDKs.

Changes to This Policy

If this privacy policy is updated, the changes will be posted here with a revised date. The extension will continue to operate on the principle of zero external data collection.
