- Local, Encrypted Storage: All your data is stored locally on your PC and encrypted using the Windows Data Protection API (DPAPI) tied to your Windows user account.

What should I do if LeakCheck finds my password in a data breach?
If a breach is detected, it means attackers may use your password for automated login attempts (credential stuffing). You should immediately change that password on all services where it is used. Enable two-factor authentication (2FA) wherever possible.
What should I do if my email address is found in a leak?
Check which specific service was breached. Change your password for that service and any other site where you reused it. Be extra vigilant regarding phishing emails, as your address is now public.
Are there limits to how many emails I can check?
Yes. For the Professional Edition, you are allowed up to 10 requests per minute and a maximum of 50 requests per day. Password checks, however, are unlimited.
Is it safe to store my passwords in LeakCheck?
Yes. Passwords and email addresses are stored exclusively on your local hard drive and are securely encrypted using Windows DPAPI, preventing unauthorized access.

I’m always weary about these login credential checkers… do they submit our credentials to some online database of leaked credentials and search for a match (which if they do is in itself a crazy security risk, they could be building a database of submitted valid credentials…) or do they download the entire database of millions of leaked credentials to a local sequestered database and that is searched locally and your precious credentials and the search results are never uploaded to any internet service? I’m always wary of obfuscating credentials with hashes as there are programs out there to do rainbow cracks of hashes so they can reverse hashes into what was hashed to try and protect it… it’s all down to the probability of the service you are using being surreptitiously malicious.
