Device fingerprint
For fraud prevention we generate a hash from non-sensitive browser characteristics (canvas, fonts, screen resolution, language). This hash helps us detect duplicate accounts and bot abuse. Without it we cannot operate the offerwall and payout features safely, so this falls under necessary processing.
