Of course I will keep your date of birth, your birth time and birthplace on file. This will come in handy every time you have a question. But just one message from you and I will remove it, not a problem. I am the only one who has access to your data and will do everything to ensure that it is placed in a secure environment.
Of course I will not sell your data, I wouldn’t even know to whom. The tax administration over here in The Netherlands wants me to fill in your address on the invoice that I will send to you. Although nowadays everyone uses email or What’s App, but alright….. Every five years I will remove all addresses on my files. If you would like me to remove your address at an earlier point: again, one message from you and I will delete it straight away.
