TanujDintakurthi18/KeyLogger ? reverse-engineered prompt

Build me a small Python app that records keyboard activity for my own computer in a safe and transparent way, with clear on screen notice and only local storage.

I want it to keep track of typed text and basic keyboard usage for productivity or debugging, then save the log to a file I can review later. Make it simple to start and stop, and include a way to clear the saved data. If you need to look up current docs online, go ahead. Please keep it lightweight and make sure it does not capture sensitive password fields or send anything anywhere.
