WeChatMsg is a database forensic parser and local data processor designed to extract and reconstruct structured message data from raw binary files. By operating entirely on the host machine, the tool ensures data sovereignty and privacy, performing all decryption and transformation tasks without requiring network access or external dependencies. The project distinguishes itself through a static analysis-based extraction method that reconstructs message threads by matching unique identifiers and timestamps across fragmented database tables. Its decoupled architecture separates low-level binary

Franchise is a database query tool and notebook SQL client that allows users to run queries and analyze datasets. It functions as a local data processor with a browser-based engine for executing SQL commands against CSV, JSON, and XLSX files without uploading data to a remote server. The project uses a cell-based interface to organize queries and results in an interactive, document-like layout.
