Yes. The project doesn't ship a copy of leaked data — you can plug in any database you like, and the project itself defaults to SQLite.Does it include any leak data out of the box?No — it only provides the checking logic and storage layer (SQLite by default). You have to source, load, and maintain the actual leaked-data set yourself.
