You only have one year from the time something goes wrong with Duolingo to file any legal claim — after that, you permanently lose your right to pursue that claim.
If Duolingo harms you — through a data breach, unauthorized charge, or other issue — you must file any legal claim within one year or you permanently lose your right to seek any remedy, which is shorter than the default period under most state laws.

REGULATORY FRAMEWORK: Contractual limitation periods engage state contract law across all US jurisdictions and may conflict with the discovery rule under various state consumer protection statutes (e.g., California UCL, which has a four-year limitation period under Cal. Bus. & Prof. Code §17208). Some states prohibit contractual shortening of statutes of limitations in consumer contracts. GDPR Art. 82 limitation periods for EU data subjects may not be contractually shortened.
