No, no. They say it can take up to 30 days, yes.
But that’s not the correct wording. It legally needs to be done under 30 days (well, one calendar month), if you’re a EU citizen.
If they do not, I highly encourage you to contact your country’s data regulator and complain about it.
Well, just a heads up, I might have wrote total bullshit (sorry about that!).
I tried to find a reference to the “one calendar month” rule in the EU’s legalese, but I didn’t find anything.
What I found is that depending on your country, the data regulator might require services to give you your data in 30 days or less, but this might not be the case everywhere in the EU. The relevant legal article for this can be found here: https://gdpr-info.eu/art-15-gdpr/
I am not a lawyer anyway, so your best bet would be to message an organization that fights for personal data protection to ask them about your rights in your home country.
Sorry about the confusion once again, as I might have been wrong!
