About this app
HimitsuBako is a secure digital safe for your most important information, including passwords, private notes, photos, PDFs, videos, and essential files.
Cloud services are convenient.
But when it comes to truly private information, convenience alone is not enough.
HimitsuBako is designed with zero-knowledge principles and end-to-end encryption, E2EE, so your secrets stay under your control.
Your data is encrypted before it is stored, and even the service operator cannot view its contents.
Instead of relying only on trust, HimitsuBako protects your information with mathematics and technology.
What you store is not just data.
It may be a private note you do not want anyone to see.
A photo you never want to lose.
An important password.
A sensitive file related to your family, work, or personal life.
HimitsuBako brings these important pieces of information together in one secure place, making them easier to protect and manage.
Key features:
・Securely store passwords and private notes
・Keep photos, PDFs, videos, and important files in one place
・Use across smartphones, tablets, and computers
・Privacy-first protection based on zero-knowledge design
・End-to-end encryption for user-controlled security
・Simple and intuitive everyday use
HimitsuBako helps you protect what truly matters — simply, securely, and privately.
Your secrets belong to you.
