Is Day One safe?

Clean risk

Day One sends entry metadata and signed-in user identifiers to pixel.wp.com after saves.

When you save an entry, the extension sends the selected page title, URL, and selected text to Day One's API. It also records save events to pixel.wp.com with the Day One user ID when signed in, subscription level, journal and entry IDs, tag count, timestamp, and browser locale/platform fields.

Where it sends data
