Any creator is welcome to use our service free of charge, but keep in mind this is an unofficial integration.
For everything to work smoothly, our service needs to receive frequent pledge updates from the creator, since only the creator has access to those details.
We recommend each creator to implement or host the updating mechanism themselves, because doing so requires full access to their pixivFANBOX account. Other than that the role assignment will be completely managed by us according to the information we receive.
If you want to try our service for yourself, you can start by logging in.
Disclaimer
FanSync is in no way affiliated with pixiv or pixivFANBOX, but we plan to support our service for as long as possible in the hope that it is useful to our users.
