Can I use `&#169; 2019 My Name` in a application created by me without registering for official copyright in India?

<blockquote>
<p>Ques: Is it necessary to register a work to claim copyright?</p>
<p>Ans: No.
Acquisition of copyright is automatic and it does not require any
formality. Copyright comes into existence as soon as a work is created
and no formality is required to be completed for acquiring copyright.
However, certificate of registration of copyright and the entries made
therein serve as prima facie evidence in a court of law with reference
to dispute relating to ownership of copyright.</p>

<p>Do I need any legal document to display that copyright or just that the work is created by me it is sufficient?</p>

<p>In all <a href="https://en.wikipedia.org/wiki/Berne_Convention" rel="nofollow noreferrer">Berne Convention</a> countries (which includes India, the US, the UK, and almost every other country in the world) copyright is automatic, and does not need to be registered in any way. In any such country, the creator may (and is advised to) include a copyright notice such as "Copyright © YYYY by Author" (where YYYY is the year of creation, and "Author" the name under which the author claims copyright). Such a notice is not required, but may avoid any defense of "innocent" or unknowing infringement, and will be evidence of who claims copyright. Registration with any national authority is not required to obtain the basic protections of copyright, but my give additional rights or protections. For example  in the US, registration can be required to obtain statutory damages, and for works by US nationals, is required before any infringement suit is filed. I don't know what benefits it gives in India.</p>
