Ask all this to keep data safe

-

1WHAT DATA IS COLLECTED?

Allow as little data as possible to be collected. The safest amount is none.

2HOW IS IT USED?

Many apps sell data to third-party companies who use it for advertisin­g purposes. The best scenario is one where the data is used only by the app company.

3HOW LONG IS IT KEPT?

Data more than a year old serves little purpose to outside parties since the most up-to-date info is the most valuable. Always seek shorter timelines.

4DOES THE APP NEED YOUR LOCATION DATA?

A number of apps automatica­lly collect this, but very few actually need it. You can generally turn this off in your OS settings.

5DOES THE APP NEED ACCESS TO YOUR CONTACTS, CAMERA, OR MICROPHONE?

Most of these features aren’t necessary, but many apps still ask for access. Granting these permission­s makes the data on your device – such as personal photos – vulnerable.

6WHERE IS THE DATA STORED?

Data laws vary by country; reconsider sharing data held in nations that may have incentive to use it for advancing political agendas (such as Russia, China and North Korea).
