Privacy
Privacy was core part of PostMaster's development. Your data is safe with you, and only you. Your data is not, and never will be, gathered/collected, stored, sold, advertised, or even seen or interacted with by PostMaster.
Even tracking is designed to be private. Tracking is loaded through Apple's Safari web browser in-app. Safari stops digital tracking, so your information is safe with you.
To check a courier's Privacy Policy, please check their website. PostMaster is not responsible for their Privacy Policies.
For information on how Apple's keeps your data in iCloud and Safari safe, please see apple.com/privacy/ and apple.com/safari/
