Features :
1. Software Freedom – Prav is Free Software or Swatantra software (please click on this hyperlink to read more). Users have the freedom to run, study, modify, share and share the modified versions. The source code of Prav app is accessible to users so that they can get it checked with the help of any programmer. Every car owner has the freedom of access to the engine of the car by opening its bonnet. Similar to the accessibility of engine of a car, Source code is like the engine of a software.

2. Software Privacy – Unlike watsapp, no personal data is collected or stolen in Prav app. XMPP means Extensible Messaging and Presence Protocol. It is an communication protocol designed for instant messaging (IM), presence information, and contact list maintenance. It provides OMEMO encryption for chats which runs on asymmetric cryptography algorithms. Practical applications of asymmetic cryptography include e-commerce based payments, chips payment based debit and credit cards, digital currencies, computer passwords, and military communication done by armies, communication done by journalists.
3. Cyber-security – Asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key. Key pairs are generated with cryptographic algorithms based on mathematical problems termed one-way functions. Security of public-key cryptography depends on keeping the private key secret; the public key can be openly distributed without compromising security. Prav App will generate a cryptographic key pair and private key will be stored on the device and public key will be shared with contacts so they can use the public key to send encrypted messages and these can be decrypted only with the secret key present on your device. This also means if you lose your device, the messages can never be decrypted (but if you want to save messages, you will be able create backups and store them separately).
4. No vendor lock-in – Prav App is convenient without vendor lock-in. Many mainstream messaging apps allow you to talk only to people who use the same app, other apps which provide choice have many manual steps and people complain they are inconvenient. Most popular messaging apps require users to download the same app and have account on the same service. Prav is interoperable with other XMPP services, which means you can switch providers and still talk to your contacts. For example, SIM cards are interoperable. If you switch from Airtel to Vodafone, you will still be able to make calls with your contacts. Similar thing is not possible with popular apps like WhatsApp, Telegram, Signal etc. If you uninstall the app, you lose all your contacts.
5. No lock in – You are not locked into our service. You can move out of our service without losing any of your contacts. We don’t stop users to talk to users from other XMPP services.
