Speakapp never knows who you are, who you're talking to, or the contents of your messages. The Speakapp app does not collect or share your information. Your privacy and security are important to us.

The main cryptographic algorithms used in sealing for messaging, supported data and metadata protection. Speakapp encrypts messages locally on a client device before sending messages. Speakapp combines multiple cryptographic techniques, starting with Elliptic curve cryptography — key exchange algorithm ECDH over Curve25519, Signature, RSA, AES256-GCM.V2

Keys are a form of identity and the backbone of Speakapp. They always come in pairs, a public key and a private key. You will never be asked for a phone number, email address, or bank account when generating a Speakapp account.

We use Zero knowledge encryption — In Speakapp, your data is stored in your device (e2ee files), in the cloud, or both. End-to-end encryption works because anyone can send you a message using your public key, but only you can decrypt it using your private key. We aim to help you become the owner of your data. This means that nobody, even us, is able to peek into your files without your permission.

Speakapp never uses third party services for managing and storing public and private keys. Remember! If you lose your private key, you will never be able to restore access to your account. So backup your private keys somewhere safe, offline!

Decentralized identifiers (DIDs) are a way to identify yourself on the internet without using a central authority, like a government or a company. Think of it like a digital passport that you control, rather than one that's issued to you by someone else.

Onion routing is the privacy-enhancing technique used on The Onion Router (Tor) network. This technique encapsulates the data traveling the computer network in multiple layers of encryption, resembling layers of an onion.

The encrypted data passes through a series of nodes (onion relays and servers), making it difficult for unauthorized parties to trace the source or the final destination of the message or access its content.

The Lightning Network is a second layer for Bitcoin that uses micropayment channels to scale the blockchain’s capability and handle transactions more fast and more efficiently.
