New submitter isaaccs writes "I'm a mobile developer at a startup. My experience is in building user-facing applications, but in this case, a component of an app I'm building involves observing and collecting certain pieces of user information and then storing them in a web service. This is for purposes of analysis and ultimately functionality, not persistence. This would include some obvious items like names and e-mail addresses, and some less obvious items involving user behavior. We aim to be completely transparent and honest about what it is we're collecting by way of our privacy disclosure. I'm an experienced developer, and I'm aware of a handful of considerations (e.g., the need to hash personal identifiers stored remotely), but I've seen quite a few startups caught with their pants down on security/privacy of what they've collected — and I'd like to avoid it to the degree reasonably possible given we can't afford to hire an expert on the topic. I'm seeking input from the community on best-practices for data collection and the remote storage of personal (not social security numbers, but names and birthdays) information. How would you like information collected about you to be stored? If you could write your own privacy policy, what would it contain? To be clear, I'm not requesting stack or infrastructural recommendations."
