Uploaded financial file contents are processed in volatile memory and are not intentionally stored as persistent file records.

Account ledgers such as email address, password hash, subscription state, quota usage, and conversion history are stored securely so the service can authenticate users and maintain account access.

If AI-assisted PDF extraction is enabled, extracted text may be sent to the configured model provider for the absolute sole purpose of completing the computational conversion request.
