Dopustite PostHogu i HubSpotu upotrebu analitičkih kolačića i pohrane u pregledniku za prepoznavanje posjetitelja koji se vraćaju i bolje razumijevanje posjeta i upita.

Dopustite Googleu, Meti i LinkedInu mjerenje rezultata kampanja i prikazivanje relevantnih oglasa. Ako je statistika omogućena, HubSpot također može koristiti oglasne značajke. Podaci o upitima i kupnjama mogu se dijeliti s oglasnim platformama.

Ovi izbori ne upravljaju praćenjem korištenja i pogrešaka u usluzi za prijavljene korisnike ni zapisima o upitima i naplati na poslužitelju. Pojedinosti su u našim pravilima privatnosti. Pravila privatnosti
