In Japanese, 規約 (きやく (kiyaku)) is typically associated with "agreement, rules, stipulations, terms of service" (Syllabus Level: N2) and represents Formal rules or regulations, especially for organizations, clubs, or online services.
On the other hand, 約定 (やくてい (yakutei)) maps to "agreement, contract, stipulation (often formal, especially in finance/law)" (Syllabus Level: N1) and represents A formal term for a promise or agreement, often in legal or financial contexts.. A literal translation of "agreement" can often sound unnatural to native Japanese speakers if mixed up!
