The Google fonts used by document360 are currently integrated directly from the Google servers (https://fonts.googleapis.com/).
Therefore, in order to comply with the requirements of the DSGVO (General Data Protection Regulation) / GDPR (General Data Protection Regulation), the consent of the users must be obtained before use.
As a simple solution, the Google Fonts used by document360 should be hosted on the document360 servers (https://cdn.document360.io/).
Obtaining the consent of the user would then no longer be necessary.
Alternatively, such a consent functionality could be provided by document360 (as they integrate the fonts directly from Google).
