Hello
i am developing an apple wallet coupon/store card integration and as each pass will hold sensitive data (tokens referencing access to the monetary amount) i am concerned of the security implications of having a passkit-pass in ios stored as well as in icloud.
Documentation is scarce if the pass is also stored on apple servers. It seems to be stored at least temporarily for synching with other devices of the same icloud user.
Can you give details to the kind of data, encryption, duration of persistence of the pass data on centralized apple servers?
Best Regards
Wallet stores passes in CloudKit. This is end-to-end encrypted, so is private to the user. You can read more about CloudKit storage in the Platform Security Guide.
