✋ A Message to Users

KOSH was created with one goal in mind: to give you absolute control over your sensitive data while keeping it protected.

I understand the importance of privacy and security in today's digital and dangerous world. That's why KOSH never stores your data on external servers, never collects usage data, and never requires internet access. Your vault is yours alone.

I built KOSH because i believed there should be a simple, trustworthy solution for personal data management that doesn't compromise on security or ease of use. No source files stored, even if some day the actual security standard encyption gets breached there are more than enought additional layers of unreversible algorythms to still make everything unreadable.

Thank you for trusting KOSH with your sensitive information.
