What the videos cover
Your own exposure, and how to shrink it.
Free and public tools, shown working, so you can check what's out there about you and do something about it.
01
Data brokers and people-search sites
What they list about you, and how to ask them to take it down.
02
Leaks and breaches
Checking whether an email or password turned up in a breach, and what to change if it did.
03
Public information
What anyone can already find, and where it comes from.
04
Privacy settings and tools
Settings, apps and services that make you harder to track.
The rule: look yourself up.
Use these tools on yourself, or with someone's permission. Using them to stalk, harass or track a person can be a crime, and it's the opposite of what the account is for. The full terms are on the terms and privacy page.

Hook, proof, handoff.
Every video is built the same way, in the same order.
Step 2
The proofThe tool, working, on screen.
A screen recording shows the tool doing the thing, and what to look for in the results.
Step 3
The handoffName and link. Your turn.
The tool's name and where to get it, so you can try it yourself instead of taking anyone's word for it.
Sponsors
Put your tool in a video.
The account covers data brokers, exposed personal information, and privacy tools. VPNs, data removal services, password managers and tools like them fit here.
Paid posts are labeled as paid, with Instagram's paid partnership label or #ad, and affiliate links are marked. You see the draft before it goes up, but the video says what the tool actually does. Only tools that would be worth showing for free get a sponsored spot. How sponsorships work.
