Phone numbers can be used to identify a person in many cases so storing phone numbers are potentially covered under GDPR. Your real problem with asking any GDPR question is that there is no to very limited case law (settled, public law suits) so it is hard to be sure about anything. Compound that with different interpretations in different countries and you have a big bag of who knows.
The question might be better as:
1. Can they catch you?
2. Will they try to catch you if they can?
3. If caught, what can they do to you?
4. Will they try to do something to you if they can?
I think the answer will be different in different countries and circumstance.
