Privacy Policy — Star for Claude

Last updated: 2026-05-22

This extension is designed with a single rule: your data never leaves your browser.

What the extension does

Star for Claude adds a star button to every message in a Claude.ai conversation. When you star a message, the extension stores a small record locally so it can show the star in a side panel and scroll you back to that message later.

What is stored

For each starred message, the following is saved:

Field	Example	Purpose
Conversation ID	e4f7a2b1-...	Knowing which chat the star belongs to
Message index	57	Locating the message position in the chat
Text snippet	first ~120 characters of the message	Showing a label in the panel and re-finding the message if its index shifts
Role	user or assistant	Coloring/labeling the panel entry
Timestamp	1716370847123	Ordering stars

Nothing else from your conversation, your Claude account, or your browser is read or stored.

Where it is stored

The extension uses Chrome’s built-in storage APIs. You choose one of two modes from the panel’s settings (⚙):

• This device only (default) — chrome.storage.local. Data lives in this browser profile only.
• Sync across devices — chrome.storage.sync. Chrome synchronizes the data across browsers signed into the same Google account. Sync is operated by Google as part of Chrome itself; this extension only uses the standard API.

In both modes, no server operated by the extension developer is involved.

What the extension does NOT do

• Does not send data to any external server, analytics provider, or third party.
• Does not read or store messages other than the ones you explicitly star.
• Does not access cookies, authentication tokens, or any other claude.ai browser data.
• Does not collect telemetry, crash reports, or usage statistics.
• Does not sell or share data.

Permissions

The extension requests two things:

• storage — required to save your stars.
• Host permission for https://claude.ai/* — required to inject the star button and side panel into Claude.ai.

It does not request any other permissions, including no broad host permissions, no tabs permission, no scripting permission.

Deleting your data

Several built-in ways:

• One star: click the × on the entry in the side panel.
• All stars in the current conversation: click the trash icon in the side panel header (two-click confirmation).
• All stars in every conversation, in both storage modes: open the panel’s ⚙ settings → “Delete stars in every conversation”.
• Or use Chrome’s own controls: chrome://settings/cookies/detail?site=claude.ai for local storage, and Chrome sync controls for synced storage.

Uninstalling the extension does not automatically wipe data already written to chrome.storage. To remove it, use the in-app delete buttons before uninstalling, or use Chrome’s per-extension data controls.

Changes to this policy

If this policy ever changes, the updated version will be published at the same URL with a new “Last updated” date. Material changes will also be noted in the extension’s release notes.
