Helios Monitor privacy policy

Helios Monitor does not collect, sell or share personal data. Nothing leaves your device. The app has no account, no sign-in, no analytics, no advertising, no tracking and no third-party code. The picture, sound and recordings stay on your iPad.

Your USB HDMI capture card shows up to iPadOS as a camera, so the app asks for Camera access to show its picture. It asks for Microphone access to meter and record the sound that comes through the card, or the device microphone if you choose it. The picture and sound are shown and measured on the device and are never sent anywhere.

Recordings are saved in the app's own folder on your device (Files › Helios Monitor › Recordings). They are never uploaded to Colormetric Labs or anyone else. You choose when to share one or save it to Photos.

Deleting a recording deletes it. Deleting the app deletes all recordings that are still in its folder.

LUTs you import are copied into the app's folder on your device. Your monitor settings are saved on the device. None of this leaves the device.

The app writes a log of what it sees: capture devices, video formats, frame and audio counts, and recording events. It contains no pictures, no sound and nothing about you. It stays on your device (Files › Helios Monitor › Logs) and leaves it only if you share it yourself, for example to send it to us when something doesn't work.

The app contains no third-party code: no advertising, analytics, crash-reporting or tracking SDKs. It is built only on Apple's own frameworks. It shows no ads and does not track you across apps or websites.

The free trial starts when you start it in the app, through the App Store. Its start date comes from Apple. To notice if the device clock is moved back, the app keeps a small record on your device: that start date and the latest time it has seen. It is stored in the device keychain and never leaves the device. It contains nothing about you.

Because it is in the keychain, this one record stays if you delete the app. Everything else is deleted with the app.

The free trial and Helios Monitor Lifetime are handled by Apple through the App Store. Apple takes the payment, and we never see your payment details, name or Apple Account. The app checks with Apple (StoreKit) which purchases are owned. This is the only time the app uses the network.

Camera, to show the picture from your capture card. Microphone, to meter and record the sound. Add Photos Only, to save a recording to Photos when you choose Save to Photos. With this access the app can add videos; it cannot read your library.

Links in the app open pages on this website, such as the Helios Monitor page and this policy. Colormetric Labs makes Helios Monitor, so these are our own pages, not advertising, and the app sends nothing about you when you open one. In your browser, this website's Privacy policy and cookie choices apply instead of this one.

Helios Monitor is not directed at children, and it collects no personal data from anyone, children included. Purchases go through Apple, so Ask to Buy and Screen Time controls apply.

Questions about privacy: support@colormetriclabs.com. If this policy changes, the new version and its date appear on this page. See also the Helios Monitor page.
