Yomizaka is in development: only the accounts our team creates can sign in. A document you upload is kept in Yomizaka's database (Toronto, Canada), visible to your account alone. When you ask for a check, the document — its text, or the PDF file — is sent to Orazaka, Krizaka's analysis engine, over HTTPS, and the result is kept with the run's id. Nothing is sold, shared or used to train a model. Deleting a document deletes its file, its text and its analyses. To ask a question or have your data removed, use the contact form.
