When using push notifications, there is a transfer of data to the providers of the operating system used by your terminal device (in the case of iOS to Apple or in the case of Android to Google), so that this data is processed outside the scope of the GDPR, in particular in the USA.
When using the translation function, there is a transfer of data to Microsoft, where it also cannot be ruled out that this data will be processed outside the scope of the GDPR, in particular in the USA.
We would like to point out that in the USA in particular there is no level of data protection comparable to the GDPR and it cannot be ruled out that US authorities and secret services may access the data. In addition, there are no or only very limited legal protection options against these accesses and other data protection violations in the USA.
There is no EU Commission adequacy decision for the USA. Standard data protection clauses have been agreed with the providers from the USA, which you can view here.
