There’s a whole concept of records management in enterprises that manages the disposal of data. It’s far more complex than just purge dates as there’s often regulatory requirements and legal discovery issues so <2% of data is actually disposed due to perceived risk.

For personal data, the concept would be simpler but still has requirements like say tax records need to be kept 7 years.

Maybe park the data with the regulator as leaving it in your hands longer than you need it is asking for trouble.
