Which search and AI services reliably discard logs? It's my understanding that if you configure your Google account correctly, logged-in searches will be discarded. However, I'm less certain about whether Google retains data for non-logged-in queries which allows for aggregation by IP address, etc. Then there's DuckDuckGo, which at least the way it's advertised, implies that they discard search strings. Their "duck.ai" service stores prompt history locally, but they claim it's not retained on their machines, nor used for training by the various AI providers that duck.ai connects to[1]. In contrast, ChatGPT by default uses non-logged-in interactions to train their model[2].
