Your Mac keeps a record of where you've been: every download and the site it came from, every Wi-Fi network it has joined, everyone you've emailed, where your photos were taken. Clearing your history and private browsing don't touch it. TrailSift checks more than 30 of these places, explains each one, and clears what you choose after showing exactly what will go. Nothing leaves your Mac, the audit script is open source, and Pro is a one-off payment, not a subscription. In five languages.
