CryptaCloud keeps your files private and still lets you search inside them — without trusting the cloud provider.
The Problem: Cloud storage is convenient, but privacy becomes a concern when you must trust a provider with your files. Many services can store your data safely, but the provider may still be able to access it.
The Solution: We built a desktop app that protects your files before they leave your device, while still allowing you to search inside encrypted files.
The Outcome: The cloud acts like a dumb storage: it only stores random encrypted file names. Inside the app, you see the real file names and can search the content to quickly find the right file.
Two common choices — and why CryptaCloud exists.
If the provider can read the files or manage access, they can access your data whenever they want.
Encrypting by yourself protects privacy, but it usually makes searching inside files very hard or impossible.
The cloud stores data but cannot understand it.
Search happens in the app without exposing your query to the cloud.
The app checks files before opening them and rejects anything suspicious.
A simple desktop app that non-technical users can use easily.
All sensitive operations happen on the user’s device first — then encrypted data is uploaded to the cloud.
The app prepares files locally (protects them, verifies them, and manages everything before uploading).
The app keeps a local index that helps you search file content privately — without sending your search to the cloud.
The cloud stores encrypted files and encrypted backups only — no keys, no logic, no searching.
The system was tested end-to-end to confirm privacy, safe storage behavior, and private search inside the app.

CryptaCloud follows a zero-trust idea: the cloud is only a storage space. The user keeps control using a desktop app that protects files before upload, and still allows private searching inside files inside the app.
