GPT Local Speed Booster runs locally in your browser.

The extension reads ChatGPT conversation responses on chatgpt.com and chat.openai.com only to reduce rendering lag in long conversations. It locally trims older visible messages before rendering and lets users load previous messages when needed.

The extension may store settings, loaded-message state, scroll restoration state, and local cache data using Firefox extension storage and browser storage such as sessionStorage, localStorage, and IndexedDB.

The extension does not collect, transmit, sell, share, or monetize personal data.

The extension does not send conversation content, analytics, telemetry, identifiers, or personal data to the developer or third-party servers.

All processing happens locally on the user's device.
