How long prompts and outputs are kept by default, in the provider's words. Where pages differ: legal or privacy page first, then help or trust pages, then developer docs, with the other in conflicts. A page that's only less specific isn't a conflict: the more specific statement is the value.

Exceptions: Grounding with Google Search: stores prompts, contextual information, and generated output for thirty (30) days; no way to disable
The main case with different retention, in the provider's words: first a model carved out of the general promise, then a feature, then a case such as flagged content. Pages rank as for Default retention; between pages of equal rank, the one naming the models. One passage only, so others may exist.
Google stores prompts, contextual information, and generated output for thirty (30) days for the purposes of creating grounded results and search suggestions. This stored information may be used for debugging and testing of systems that support grounding. There is no way to disable the storage of this information if you use Grounding with Google Search.
