leak-check is a personal information breach detection service that checks whether user data appears in widely distributed internet datasets.
The tool addresses the problem of individuals not knowing whether their personal information has been compromised in data breaches. It provides an interface to query whether personal data exists in leaked datasets circulating online. The service operates on a principle of privacy protection: it does not log query records, does not provide additional information beyond confirmation of presence in leaked data, and emphasizes the user's right to know the status of their data.
The project uses SQLite as its database backend but does not provide data copies; users can substitute any database system they prefer. The tool is designed for individuals concerned about their data exposure in publicly distributed breach datasets. Development setup is facilitated through an installation script for quick environment configuration.
The project maintains an active issue tracking system on its repository for bug reports and feedback, indicating responsiveness to user-reported problems and feature requests.
