Apps by MerKuri.

MerKuri Let Us Begin extends its practice into software: focused applications that carry the same discipline we bring to enterprise consulting — privacy by design, deliberate simplicity, and tools that respect the people who use them.

Free Apps

Fully functional, free to download, and free of ads, analytics and tracking — now and always.

DocsPers

Private vault for your phone

Version 1.0 · Free · iOS 17+ and Android

DocsPers is a private vault for your phone. It keeps your sensitive PDFs, pictures and other files encrypted on your device and in your own private Cloud. The developer cannot see your files.

Files, their names, your notes and your folder names are encrypted on the device before they are saved or synced. The key lives in your private Cloud Keychain, so your files follow you to every smart phone and smart device you sign in to — and only yours.

On-device encryption for every file, name, note and folder
Keys held in your own private Cloud Keychain — never on our servers
Locked with Face ID or your smart phone passcode
Encrypted backups you can store anywhere
Ready-made Suggested Folders: IDs, Cards, Medical, Taxes
Free, with no ads, no analytics and no tracking
