Is Clipboard History Manager - Secure, Fast, and Open Source Safe? — Extension Safety Profile

This clipboard manager requests access to read and write your clipboard (clipboardRead, clipboardWrite), store large amounts of local data (storage, unlimitedStorage), and interact with the current tab (activeTab, scripting) — typically to insert saved clippings into web forms or text fields. It can also add items to the right-click menu and present a side panel. For a productivity tool that offers history and quick paste, this set of permissions is generally expected, though the combination of clipboard access and the ability to modify page content means the extension has considerable reach into the data you copy and the pages you visit.

Users of any clipboard manager should understand that its core function grants it visibility into sensitive information like passwords, codes, or personal notes placed on the clipboard. Since this extension also declares it collects personally identifiable information, reviewing the privacy policy and using a tool that does not need to sync data externally (if possible) are sensible steps. Open-source claims can allow community auditing, which adds trust, but verifying the published source code matches the installed version remains important.

In the fact sheet, Maintenance & Ownership scored perfectly, indicating the extension is actively maintained and recently updated — a strong sign of developer commitment. The weakest area was Publisher & Identity (60/100), suggesting limited transparency about the company or individual behind the tool. While not a red flag on its own, this lower score may give a careful user pause to check the developer’s background and the authenticity of the open-source repository before granting broad clipboard access.
