FAQ
What Patreon tier do I need?
Any PRO-level tier on patreon.com/4kfilmdb unlocks full access. Check the membership page for current pricing.
Does my 4KFilmDb account email need to match Patreon?
No · use any email for your 4KFilmDb account. The verification form links your Patreon username to your account manually, so they don't need to match.
How long does activation take?
Within 24 hours of submitting the verification form. You'll receive an email confirmation once PRO is active on your account.
Does PRO cover all 4KFilmDb tools?
Yes · one membership unlocks PRO metrics across Streaming Reference, UHD Reference and My Library. Same sign-in everywhere.
What happens if I cancel Patreon?
PRO access continues until the end of your current billing period, then reverts to free. Your account and data are never deleted.
Is there a free trial?
No formal trial, but the free tier gives you full access to all verdicts, filters and the disc score database. PRO adds the raw measurements behind the verdicts.
