Hardware wallet makers have leaked customer data more than once. Almost everyone who has bought Bitcoin or a hardware wallet with ID has a name and address sitting in a database somewhere, and many of those databases have leaked.
Leaked data cannot be pulled back. So the goal is twofold: make sure a leak can never lead anyone to your Bitcoin, and shrink how much of your personal information is out there. Here is how we think about it.
1. Distribute your digital assets geographically
If everything you own sits in one drawer, one break in is enough. Spread your hardware wallets and backups across several secure locations, such as a safe deposit box, a home safe, your attorney and trusted family.
The rule that makes this work: everything stored in any location is encrypted. Then a compromised location reveals nothing useful on its own. This is what the Citadel Vault is built for. Your Vault Key is split across Vault Cards, so no single card, place or person can open your vault alone, while your heirs can still recover everything.
2. Remove your home address from the internet
Your home address is the most dangerous detail in a leak, because it links your name to where your hardware and backups are. It tends to show up on people search sites, in phone and address directories, and in search results. Each one has to be dealt with separately, and what is possible depends on where you live.
3. Check and remove your data from data brokers
Data brokers collect and sell names, addresses, phone numbers and relatives. That is how a leaked customer list turns into a front door. Some governments now offer ways to opt out from many brokers at once, and paid services exist, but handing a removal service your full details puts them with one more company. Brokers also re-list people, so this is a habit, not a one time job.
4. Hide what cannot be deleted
Some records, such as property records, are public by law. Search engines offer ways to hide personal details from their results, which keeps them away from most people who look you up.
5. Stop adding to the trail
The best leak is the one that never happens. Keep Bitcoin purchases and deliveries separate from your home address and your everyday identity, protect your credit, and talk about Bitcoin as little as possible, online and offline.
Where to start
Every situation is different: where you live, what you hold and who might be looking. Our Protecting Yourself After a Data Leak service walks through each of these steps with you, one on one, and members of the Bitcoin Citadel community share what has worked for them.
