+rights-intro-point-4-unbranded = Alle relevante privatlivspolitikker for dette produkt bør være oplistet her.
+rights-intro-point-5 = Nogle { -brand-short-name } funktioner gør brug af webbaserede informationstjenester, men vi kan ikke garantere at de er 100% korrekte eller fejlfrie.

Vi kan dog ikke garantere at denne information er fyldestgørende eller fejlfri. Eksempelvis kan Safe Browsing-tjenesten ikke altid identificere risikofyldte websteder og kan tillige fejlagtigt blokere for sikre websteder. Ved positionsbevidst browsing vil positioner returneret af vores tjenesteudbydere kun være omtrentlige og vi garanterer ikke for præcisionen.
+rights-webservices-term-2 = { -vendor-short-name } kan afslutte eller ændre tjenesten når de ønsker dette.
+rights-webservices-term-3 = Det står dig frit for at bruge de i { -brand-short-name } medfølgende tjenester og { -vendor-short-name } giver dig rettighed til dette. { -vendor-short-name } og dets licensholdere forbeholder sig alle andre rettigheder vedrørende disse tjenester.

+rights-safebrowsing = <strong>SafeBrowsing: </strong>Deaktivering af Safe Browsing funktionen er ikke anbefalet da det kan resultere i at du besøger usikre websteder. Hvis du ønsker at deaktivere denne funktion fuldstændigt, kan dette gøres ved følgene trin:

Vi kan dog ikke garantere at denne information er fyldestgørende eller fejlfri. Eksempelvis kan Safe Browsing-tjenesten ikke altid identificere risikofyldte websteder og kan tillige fejlagtigt blokere for sikre websteder. Ved positionsbevidst browsing vil positioner returneret af vores tjenesteudbydere kun være omtrentlige og vi garanterer ikke for præcisionen.
+rights-webservices-term-2 = { -vendor-short-name } kan afslutte eller ændre tjenesten når de ønsker dette.
+rights-webservices-term-3 = Det står dig frit for at bruge de i { -brand-short-name } medfølgende tjenester og { -vendor-short-name } giver dig rettighed til dette. { -vendor-short-name } og dets licensholdere forbeholder sig alle andre rettigheder vedrørende disse tjenester.

+rights-webservices-term-6 = { -vendor-short-name } må fra tid til anden opdatere disse vilkår efter behov. Disse vilkår må ikke ændres eller annulleres uden skriftlig aftale med { -vendor-short-name }.
+rights-webservices-term-7 = Disse vilkår styres af loven i Californien, U.S.A., dets conflict of law provisioner.
