To be transparent: the extension reads your LinkedIn data the way your browser would, which LinkedIn’s terms don’t formally allow. Safeguards greatly reduce the risk, without removing it entirely:
- an adjustable pace (Careful, Measured recommended, Sustained) with hourly and daily quotas;
- random pauses, a time window and optional weekends;
- an automatic 2-hour pause if LinkedIn pushes back;
- no message sent without your click, one at a time.
Everything is set in Settings → LinkedIn, with a sync log.
