What is Zero Knowledge software?

Zero Knowledge software is designed in such way that developers of such software do not have access to user's data.

Your files are encrypted on your devices with special Key created from your password. This Key or your Master Password is never sent to our servers, so the only person who can decrypt and see your files is YOU.

What is Master Password?

Your Master Password is being used to encrypt your files. If you loose your Master Password your data can not be recovered. Your Master Password is never sent from your device, so it can not be reset by us. Write it down.

How does Cloud Backup works?

You can setup Google Drive backup and we will use it to upload your encrypted files. Nudex will ask for limited permissions and be able to access only files created by Nudex.

How does Sharing work?

You can choose to share your files with your partner and it will be done in a secure way by using Public Key cryptography.

Each File is encrypted with it's own File Key. Each user has own Public and Private keys pair (RSA 2048). To share the photo, your device will request Public RSA key of your partner, encrypt your File Key with it and send it back to your partner along with Encrypted File.

Your partner will decrypt your File Key with own Private RSA key and be able to decrypt and see your shared file.

We utilize Google Drive to deliver the actual encrypted files to your partner.
