Can I use GPL3 code and keep a web app proprietary

Question

I have a proprietary web application that I host. If I added 3rd party code to it (in the form of a Python module) that is licensed under the GPL3 do I have to licence my app under GPL3 too? My understanding was that under GPL2 you didn't have to release your code if it was SaaS , but under GPL3 you do. Is my understanding correct?

Answer 1

If you're referring to the "TiVo" clause it only applies to code embedded in a device you sell.

Answer 2

I think you're thinking of the Affero GPL 3 not the regular GPL 3.

But with licencing you should read them all carefully and make your own mind up, not take other people's advice.
