Epic uses automated systems, including machine learning, to detect fraudulent purchases, account theft, and other unauthorized activity across its games and storefront. This is disclosed in Epic's privacy policy but the specific systems used are not publicly described in detail.

Epic's privacy policy, updated November 2025, states the company uses information "to detect and prevent fraud, cheating, hacking, account theft, misuse, and other unauthorized activities." The policy also confirms that Epic trains "machine learning technologies to detect and moderate illegal, harmful, toxic, and fraudulent conduct and content," and lists "anti-cheat and fraud prevention technology providers" among its service partners. Beyond these disclosures, Epic has not published details of how its fraud systems work. Consumers most commonly encounter outcomes of this system when virtual currency is revoked following disputed payment chargebacks.
