Hi @NStojkovski,
As far as I know it’s not possible to prepopulate the Country/Region field based on IP country. The website visitors would have to manually select this.
Regarding your question on consent, it’s either on or off. The GPDR options cannot be displayed dynamically. Keep in mind that there is no such thing as a general GDPR consent. Depending on the country, it’s required to capture the consent into processing a contact’s personal data and the consent into communicating with a contact (this is what HubSpot’s subscriptions are referring to).
You could consider displaying different forms on different language versions of the same landing page. If that’s not possible, I would recommend following the strictest guidelines on your form. I can’t advise on what those would be (see disclaimer below) but usually, consent into communication cannot be required and must be a separate checkbox, consent into data processing can be another checkbox or implicit within the consent notice.
(This post does not constitute legal advice. When in doubt, always discuss with a legal professional.)
Let me know if you have any follow-up questions.
Hope this helps!
