The privacy of our user's personal information is very important to us and we've protected this information through the dedicated design efforts of our security team.
Databases containing sensitive user data aren't accessible from our site. They're encrypted and can't be decrypted without access to multiple highly secured systems. Access is strictly controlled and monitored.
All documents uploaded to our website are watermarked. This means that in the unlikely scenario our security systems are breached, your documents will not be re-usable elsewhere.
The most likely scenario for leakage of personal data would be user-specific, rather than a breach of the database as a whole — that is, if someone gained access to your personal login credentials due to the account not being properly secured.
Even if an account is compromised though, the viewable information is very limited.
