# Updating Your App Permissions

To ensure Threadly can send messages to your channels (including private ones) and track reactions and clicks, it needs specific permissions.

If you see this banner at the top of your app, it indicates Threadly may be unable to properly send messages for you.

To resolve this, click **Update Permissions** in the banner — or re-authorize by visiting [How to Install Threadly](/threadly/getting-started/how-to-install-threadly.md). This takes a few seconds and won’t affect your existing messages, groups, or workflows.

**Threadly respects your privacy: Your channel content (other than Threadly messages for analytics and tracking) is never saved on Threadly’s servers.**
