Ionic Camera Temporary Cache storage

I have created an app where you can send pictures with other data (a lead for a sales agent). When the device is offline it will store the lead and the temporary location of the image in a list of unsent leads (localstorage).

My question is: How long are the images stored in the cache location at Android an iOS? When the app is started a few days later and it has connection and it tries to send the old photos, will they still be there?

(I know that in Android an user can manually clear cache)

For Android the location is: file:///storage/emulated/0/Android/data/nl.app_id/cache/
