ClipMemo stores all clipboard data exclusively in your browser's local storage (browser.storage.local). This data never leaves your device. ClipMemo does not collect, transmit, or share any personal data, clipboard content, or usage statistics with any third party or external server. No analytics, no telemetry, no accounts. The extension requires the <all_urls> permission solely to inject a minimal content script for reading clipboard content — a technical requirement of the Firefox clipboard API. No page content is ever read, stored, or transmitted. You can export or delete your history at any time from the extension's Settings panel.
