What “privacy-safe” analytics actually means in an app
It is not a marketing label — it is a set of collection choices you can explain to a regulator and a user.
Privacy-safe analytics starts with purpose. If you cannot name the product decision an event supports, it should not ship.
Minimisation is more than deleting email fields. Device IDs, precise location, and free-text inputs can re-identify people when combined. Treat quasi-identifiers with the same caution as direct PII.
Aggregation thresholds matter. A cohort of three people in a rural postcode is not anonymous. Set floors before you publish dashboards.
Consent is not a substitute for good design. Collect less by default; ask clearly when you need more.
Document the pipeline. When legal asks “where does this field go?”, a one-page data map is worth more than a long policy PDF.
