The document discusses best practices for secure data management and privacy. It recommends that companies: 1. Design opt-ins that require explicit user permission rather than pre-checked boxes and consider micro-consent. 2. Respect user rights to modify, correct, erase and update personal data. 3. Take a preventative rather than remedial approach to privacy by designing it into products and services from the start.

If I pull data from an API, do I really
need all the fields of data that I could
get, or do I narrow it for the specific
purpose of this product?
When thinking about geolocation data–
do I really need it? And if I do capture
geolocation data, what are the risks
associated with that?

12. Minimize collected data

13. Reduce sensitivity of data
Aggregate and statistically anonymise data or extract the features of
interest before sharing
e.g. use age group instead of age

14. Cultivate transparency and honesty
Be open and clear about how you protect and use private data

15. Protect whole data lifecycle with End-to-End security
