Short version

No conversation exfiltration

LightSession does not send conversation text, prompts, responses, or usage events anywhere. It only trims rendered DOM nodes locally to keep long ChatGPT threads responsive.

Privacy details

Overview

LightSession exists to reduce ChatGPT UI lag by trimming old DOM nodes after long sessions.

It only needs the permissions required to run on ChatGPT pages and store your local preferences.

Permissions Explained

  • storage saves settings such as enabled state and message-count thresholds locally.
  • Host permissions for chat.openai.com and chatgpt.com allow the content script to run only on ChatGPT pages where trimming is needed.

Local Storage Only

Settings are stored in browser.storage.local.

  • No remote sync service.
  • No server-side profile.
  • No external visibility into your extension state.

Conversation Privacy

LightSession only trims what the browser renders. It does not rewrite or delete your actual conversation on OpenAI's servers.

  • It does not send prompt text or replies to us.
  • It does not persist conversation content externally.
  • Refreshing the page restores the full thread from the normal ChatGPT source.

What we do not do

✓ We do not read and upload your ChatGPT conversations.
✓ We do not send analytics or telemetry to third-party services.
✓ We do not inject ads, trackers, or sponsored UI.
✓ We do not require account creation.
✓ We do not sell data because nothing is collected server-side.

Changes

If this policy changes, this page will be updated. Given the product direction, significant privacy changes are unlikely.
