Privacy Policy
Last updated: 11 October 2026
Ductly doesn't collect any personal data. There are no accounts, no analytics, no advertising and no tracking, and the developer has no server that your information could be sent to.
What Ductly stores, and where
- Your units' settings (names, Home and Away addresses, zone names and refresh interval) are stored on your device.
- Each unit's PIN is stored in your device's Keychain.
- Your Apple Watch receives the same settings and PINs directly from your iPhone using Apple's Watch Connectivity, so the Watch app can work.
Deleting a unit in Ductly, or deleting the app, removes this information from your device.
Who Ductly talks to
Ductly only connects to the SkyFi unit addresses that you enter. These are usually your unit on your home network, or a remote address that you set up yourself (such as dynamic DNS or a reverse proxy). That traffic goes directly between your device and your air conditioner.
SkyFi units only support plain HTTP, so traffic to an Away address on the internet, including the unit's PIN, isn't encrypted unless you put HTTPS in front of it with your own reverse proxy. Ductly warns you about this when you enter such an address.
Purchases
Ductly Pro is bought through the App Store. Apple handles payment, and the developer doesn't receive your payment details. Ductly only checks with the App Store whether Pro has been purchased.
Crash reports
If you choose to share analytics with app developers in your device's settings, Apple may provide the developer with anonymous crash reports. These don't identify you.
Children
Ductly doesn't knowingly collect information from anyone, including children.
Changes
If this policy changes, the updated version will be posted on this page with a new date.
