Is Sticky Notes App safe?

Adds a local side-panel workspace for sticky notes, to-do lists, tags, and task checkboxes.

This extension lets you create and organize digital memos in the browser side panel, with colored notes, multiple tags, drag-and-drop organization, task checkboxes, subtasks, shortcuts, and one-click copy. The store description says notes are stored locally in the browser, with no cloud sync or account creation, and includes a blur mode for hiding note content on screen.
