Looking for a no-code app builder that doesn't train on my project data?

I’m in North Dakota and I’ve been using a no-code app builder to put together a small internal tool for a volunteer group I help with. The convenience is great, but I’ve started wondering what happens to the project data and prompts I feed into these platforms. I keep hearing different things about whether AI-assisted builders retain or train on what users submit, and the privacy policies I’ve skimmed are not exactly clear to me.

I’m now considering switching to something else, but I don’t want to trade one data-handling problem for another. My main concern is finding a builder where I can reasonably understand and control what’s stored and whether my inputs get used for model improvement. I don’t need anything fancy, just something workable for a small project.

For those who’ve looked into this more than I have, what do you check first in a tool’s terms before committing? Are there options that stand out on data handling, or is this mostly unavoidable with AI builders right now?
