No Spruce that is true. But It is a legitimate need to keep certain details for e,g, tax and accounts. And you can modify the record so that it reads minimally ...
So that Mr and Mrs Jones, 99 Station Rd Anytown
Can become what you like within legitimate reason to maintain accounts/tax records
Title: None
House number ??
Address line 1 Station Rd
Address line 2 Removed under GDPR request
Address line 3 Minimal details retained for HMRC Accountancy purposes
Initially I had thought about Mr & Mrs Anonymous but I like your suggestion better.
For the moment we will leave things as they are. I know all of my customer's names as I ask all new ones their names, but sometimes need to look on the system as a prompt. The computer between my ears used to be good at retaining info, but unfortunately it doesn't work well any more.
We don't talk about our customers to others and we don't share info. On occassion I have warned other cleaners off customers who want cleans and don't pay, but that about all.
If someone broke into the van during the day and stole our PDA with Pocket George on it, then the only info on there that could be worth anything to is a fellow windie.
