PRIVACY Before the first question, KnowItOwl! explains what data is processed and asks for permission.

Permission can be withdrawn at any time from Settings, which stops new AI questions on both iPhone and Apple Watch until it is allowed again. Message content and stored audio are encrypted on the device before they are saved to Firebase. See the privacy policy for retention and service-provider details.
