Any public disclosure of your product (which could be as simple as a demo to potential investors not under NDA or a YouTube video), &quot;publications&quot; including web pages, and &quot;offers to sell&quot; which may include advertising. Announcing the name of your product probably is not a problem, but a splash page that describes how it works or on boarding users could make your idea public.  The details can get tricky.<p>If you think you might want a patent, don&#x27;t hesitate to talk to a patent lawyer to make sure you are not waiving your rights, otherwise you&#x27;ll regret it. You can always choose not to spend money on the patent application but make that decision after you know what you are doing.
