Privacy Policy
Last updated 19 September 2026
Comark is an iPad annotation tool that pairs with a Mac or Windows companion over your local network. This policy explains exactly what the app does with your data. It is short because Comark collects very little.
What stays on your device
Screenshots, annotations, footer notes, history, your interface language and your speech-provider choice are stored only on your iPad. We operate no account system and no server that receives your content. Uninstalling the app removes this data.
Screenshots and the local network
When you capture a screen, the image travels directly between your iPad and your own computer over your local network, encrypted in transit. It never passes through our servers.
Voice notes and speech recognition
Voice annotation records audio only while you are actively dictating. Where that audio goes depends on the provider you select in Settings:
- Apple Speech Recognition (the default): audio is handled by Apple's system framework under Apple's own privacy terms. Comark does not receive or retain it.
- A third-party provider you configure (Alibaba Bailian, Volcengine, or any OpenAI-compatible service): audio is sent directly from your iPad to that provider using the API key you entered, and is subject to that provider's privacy policy. Comark is not an intermediary and keeps no copy.
Recordings are not saved after transcription. API keys you enter are stored in the iOS Keychain on your device and are never transmitted anywhere except to the provider they belong to.
Purchases
Comark Pro is sold through Apple's In-App Purchase. Apple processes the payment and tells the app only whether your access is active. We never see your payment details.
Tracking and analytics
Comark contains no analytics, no advertising, and no tracking of any kind. Nothing about your usage is reported to us or to third parties.
Children
Comark is a productivity tool intended for general audiences and does not knowingly collect information from children.
