Is Cluing - Shareable Notes on Web Pages safe?

Low risk

Cluing registers the URL and title of each page you visit and uploads per-paragraph reading activity to its servers.

On every page, the extension creates a document record with the page address and title, then tracks which paragraphs you view, how long you dwell on them, and how often you copy or click them. Paragraph text is sent as hashes rather than raw text, and the data is uploaded to Cluing's API about once a minute.
