Technology

PrivateStorage relies on Open Source technologies.

As firm believers in the protection of our users’ privacy, we offer a private, secure and end-to-end encrypted solution to give you full control over your data. We design for privacy and security as a baseline for PrivateStorage, so that you as an individual—not us, or third parties—determine who can access your data on the storage service.

Security by Design

What PrivateStorage means by “security” is something different from what most companies do. Utilizing end-to-end encryption and accountless authentication, we at PrivateStorage never have the ability to read or modify your data. This makes it easier for us to maintain the security of your data, and to keep our users anonymous. This is what we call Security by Design.

Client-Side Encryption

PrivateStorage automatically encrypts any folders being stored on the PrivateStorage cloud, even before leaving your device. This ensures the confidentiality and integrity of your data. We cannot read your data, only see its encrypted form. Only you, and whoever you choose to share them with, has access to the encryption keys to be able to read the data.
Decentralized Storage

Decentralization and redundancy

The PrivateStorage client app encodes your uploads into multiple, unique chunks of cipher (encrypted) text, then spreads those chunks (called shares) out among our servers on the PrivateStorage grid. Extra shares are created and saved on multiple servers for data parity. In the event of data loss or corruption, these parity shares can reconstruct the data with minimal performance impact.
Accountless Authentication

Accountless Authentication

As we don’t ask you to sign up for an account, accessing your securely stored data with PrivateStorage is done through the use of special codes, known as capabilities, stored locally on your device.
Invite Codes

Invite Codes

PrivateStorage uses a short combination of numbers and words to allow folder access (e.g., 9-hamburger-chairlift, 1-forever-alone) By knowing and using the same shared "invite code," any two devices can quickly and easily establish a secure connection through which folders can be securely transmitted.

Commitment to Open Source Technologies

PrivateStorage is built on a commitment to transparency and open source technology. By using technology that is publicly reviewable, we maintain our value of transparency and allow for our users to know exactly what happens to their data.

Tahoe-LAFS

Tahoe-LAFS is an open source decentralized cloud storage system. PrivateStorage uses it to encrypt and distribute your data across multiple servers on its storage grid. In the unlikely event our servers fail or are taken over by an attacker, the entire file store continues to function correctly, preserving your privacy and security.

Gridsync

Provides an easy-to-use interface that allows for the user to seamlessly access their stored data on the most popular platforms through PrivateStorage.

Magic Wormhole

Magic Wormhole makes it possible to easily, quickly, and securely transfer credentials from one computer to another, with short, human‑pronounceable "invite codes".

A file-syncing utility that automatically makes a folder and its contents look the same on two different computers via Tahoe-LAFS.

Your Data, Your Control

Data Leases

Pay only for the space you actively use

Unlike other cloud storage providers, we feel you should not have to pay for storage space you are not actively using. In our system, you pay for the specific amount of space you use and for a set time span. If you wish to use more storage space, or use it longer, you simply use more of your PrivateStorage Credits.
Pay with anonymous tokens

Pay with anonymous tokens

PrivateStorage Credits work to control access to the storage service, while also maintaining our users’ anonymity. By detaching a user’s online activity from an 'account’ or any specific payment methods, we make sure we do not know your identity.

Safe, Secure, Redundant, Recoverable

Should you lose access to your computer, then you can restore access to your data from another device, provided you have the Recovery Key. Your personal Recovery Key is a brief text file that contains only enough information to allow you to regain a connection to the storage grid and access any previously stored folders. It is critical to create a Recovery Key as soon as you start using PrivateStorage.
