By the way, is the text entered sent to any servers? Not that it matters to me much when it comes to poems, but as someone who cares about privacy, I have to ask. :D
Regardless, this looks awesome and useful!
To answer your question: all of the "computation" is done client-side, but depending on which features you use, the client might ask the server for data at a word level (like "give me all the rhymes of 'trust'" or "how many syllables are in 'privacy'"), so I guess in a sense your text can be sent to the servers, but never in an aggregated way.
Also, as someone who also cares about privacy, I can tell you:
- I don't keep any server logs - The only tracking I do (to get traffic numbers) is self-hosted and uses Fathom[1] (which respects privacy in a variety of ways) - I jump through a fair number of hoops to prevent the other third-party tools (Bugsnag[2] and Appzi[3]) from collecting personally identifiable information
While the details of the above might change at some point (I may eventually add some basic server logging, for example), the spirit will not. I don't want to collect any data that I don't absolutely need.
Hope that's helpful!
