LispPad is a sandboxed application, i.e. it only has access to data authorized by the user. Independent of such authorizations, the LispPad application itself neither collects nor transmits any personal data. Documents written by the user with LispPad are only saved in places selected by the user. Files generated by programs executed by LispPad are only saved in places determined by the program and authorized by the user. Individual application settings are stored as user settings on the device of the user, but might get backed up or synced by the operation system.
