Currently the Kagi Translate Android app has a feature to delete past history, but no feature to disable saving history entirely. For certain use cases I think it would be better to support disabling history entirely. For example, when using Kagi Translate frequently in trips to foreign countries, the translate history can be a way of retracing the actual trip of the user.
A setting should be added to Kagi Translate app's settings page to disable history. It would be a toggle so that the user could easily toggle on and off translation history at will. Additionally, when turning off history, a dialog could ask whether the user also intends to clear the currently saved history.
