You may read, run, modify and distribute the code. If you modify it and offer it as a network service, you must offer the modified source to its users. If that does not suit you, the commercial licence exists.
The name "PRISMA" and its logo belong to PRISM Creations Ltd.; the licence does not grant trademark rights. If you distribute a modified version, use a different name and logo so nobody confuses it with the official app.
