Because LocalPDF operates entirely offline and does not sync to the cloud, there is no remote "account data" for us to delete. If you want to completely erase all data associated with LocalPDF, you just need to delete the local files on your Mac.
In the LocalPDF app sidebar, right-click on any document and select "Delete." This will immediately purge the document's text extraction, generated vector embeddings, and all chat history associated with that document from your local SQLite database.
If you wish to completely wipe all LocalPDF data, including all settings, databases, vectors, and cached documents, securely empty the following directory from your Mac:
If you also wish to delete the downloaded AI foundational models used by LocalPDF, you can cleanly remove them using your Mac's built in storage manager under the System Settings > Storage > Developer or NaturalLanguage models section.
