A focused reading path

Purpose, boundaries, and restraint.

Explore how to give collection a clear purpose, limit event properties, and make decisions about the entire data lifecycle. These articles connect privacy-minded planning with event specifications that developers can actually test.

Privacy-first: where to begin

Read the guides below in the order that fits your question. Each article includes a relevant primary reference, an original worked approach, and links to the next useful concept. Keep sample illustrations separate from actual site observations as you apply the ideas.

Ask what the decision needs before adding another field or identifier.

Test the boundary

Make the chosen permission rule visible in the implementation tests.

Review what remains

Document access, exports, retention, and the retirement of unused events.
