Why we built a spam filter you can actually train
The filters built into Gmail and Outlook learn from everyone at once — and you can't steer them. Blockjay keeps a filter trained only on your corrections, so it fits how you actually use email. Here's the thinking behind that choice, and why “your filter, not a shared one” is the whole point.

We never delete your mail. Here's how we mean it.
Plenty of tools say they “clean” your inbox and quietly bin things. Blockjay only ever moves mail — spam goes to a private quarantine, saved in full and restorable in one tap. The filter deletes nothing; only you do. This is the trust contract the product is built around.
