As an application developer, how can i guarantee that the data that I am reading is not stale? I am not able to find the answer to this in the documentation.
Do chainlink data-feeds have specific guarantees about returning new data within N-Blocks?

I interpret your question as asking about data "freshness". "Each Chainlink Price Feed runs on a specific blockchain network and regularly updates with fresh data based on predefined parameters. " ref
Also take a look at timestamps on retrieved answers
Example ETH/USD feed parameters - note "Last Update" parameters (link)
