What data does your app keep on it's users?
I am new to programming apps and I am wondering what are your apps storing on the users? Example being Pokemon go was taking photos of the inside of peoples homes to get all details of users location, plus what it looks like inside their home and all their products they buy.
But what do smaller developers track on their users that could be beneficial for you/me as a developer?
I only track information on (traceable) users for which they have explicitly given me their consent (ranging from personal information to location tracks). Besides that I keep some general records for SEO optimization, but this cannot be tracked back to users.
The information you keep on users should be relevant to the problem you're solving. As such I have no problem getting users to consent on location tracking, but only use this information for the use case which I have laid out to them. I currently don't have the resources to expand operations beyond that anyway.
Do not underestimate the liability such information brings with it. As such I try to get rid of information as soon as possible. Sometimes that's after years for legal reasons, while in other situations that's as soon as an realtime algorithm is done processing the data.
Creating CRUD screens is easy. Handling data responsibly and effectively is the hard part.
Where can I learn about proper data handling? Do you have a certain website or course I could look at
In Europe we do have the GDPR laws which provide a reasonable framework for data processing requirements from a legal point of view. If you manage to comply with that I think you are already acting far more responsible and ethical than most parties.
As my philosophy on data processing has formed over years of practice I don't really have any other resources readily available.
