# LeapYear

**Canonical:** https://apis.io/providers/leapyear/  
**APIs profiled:** 1

LeapYear Technologies built an enterprise platform for differentially private analytics and machine learning, letting organizations run statistics, SQL-style queries, feature engineering, and supervised and unsupervised model training against their most sensitive data while a mathematically provable privacy guarantee bounds what any single record can leak. The product shipped as a self-hosted server, LeapYear Core, driven by a first-party Python client library that exposes databases, tables, views, users, groups, permissions, privacy profiles, and per-database privacy budgets as programmable resources. Snowflake announced its intent to acquire LeapYear in February 2023 and closed the acquisition for $62.0 million in cash, folding the differential privacy technology and team into the Snowflake Data Cloud clean-room capabilities. The standalone company surface is now retired: leapyear.io no longer answers on HTTPS. The surviving public developer surface is the hosted LeapYear Python client reference for version 4.1.1.
