More on Date & Time questions

Time questions display a time picker. The time collected is the time selected, no timezone data is attached to it. This means if you select 17.34, it will be saved as 17.34 no matter what timezone you are currently located at. This is done on purpose. For a timezone dependent timestamp, we automatically add a "Created At" timestamp with timezone offset to each entry when saved.

These "Created At" timestamps get downloaded with the rest of the data from the web application. More on downloading data.

Date questions behave exactly ike time questions.

More on Location questions

Location of the user device can be acquired adding a location question. The user needs to actually tap on the "Update Location" button to get the location data stored. Basically tapping that button gives the app the consent to store the user location. It cannot be done automatically for this very reason (privacy issues). If you ever used Facebook or Instagram, you might have noticed they use the same approach, as when adding a post the location needs to be added separately. Moreover a location question cannot be required: a user might not want to answer that, or the device might lack GPS capabilities (for example a cheap Android tablet).
