Privacy policy
SkyTimer was built with privacy in mind. None of your identifiable information is shared with us through the app.
SkyTimer and your data
Here's how your data is used.
No identifiable user information is shared
By design, you don't create an account with SkyTimer, and your use of the app is completely anonymous. You need to sign in to the App Store with your Apple ID to download the app, but Apple does not provide us with that information. Apple does provide us with general trends about the app (number of downloads, regions users are in, and so on), but there is no way for us to identify a specific user with that information.
Your GPS location isn't tracked
When you create a trip in SkyTimer and use GPS to detect your location, that information stays on your device. SkyTimer determines the airport you're at by checking your GPS location against a worldwide airport database stored on your device. Your GPS location is never sent to a server.
Your trip data isn't stored on our servers
When you complete a trip, its data is saved on your device and then synced to your iCloud account. That lets another device tied to your iCloud account (an Apple Watch, for example) receive and sync that data. None of that information is available to us, and it is securely stored on Apple's servers.
Even a SkyTimer Plus subscription purchase is anonymous
When you subscribe to SkyTimer Plus, Apple manages and stores all of your payment information. We're not provided with any information about your method of payment, and that data isn't stored on our servers.
To grant you access to SkyTimer Plus, SkyTimer sets an anonymous Subscription ID unique to your Apple account. When you subscribe, that Subscription ID is passed to Apple, and Apple then notifies us that the Subscription ID has an active subscription. That ID is stored on our servers so we can reauthorize your SkyTimer Plus subscription (if you get a new phone or watch, for example), but we can never tie it back to your contact information or email. Over time, Apple continues to notify us of your subscription status using that Subscription ID.
For customer support, your Subscription ID is available in the SkyTimer iPhone app under Settings › About SkyTimer › SkyTimer Plus. We may ask you for that ID to help troubleshoot an issue, and that is the only time we would be able to tie your Subscription ID back to you.
You can choose to share anonymous crash reports
Apple provides us with crash reports for SkyTimer, but only from users who have opted in to share that data. That information is still anonymous and is used only to improve the app and fix bugs.
We won't share your email address
If you sign up for our mailing list, we'll have your email address and will store it securely. We'll never share it with another company, except the email service provider we use to send you our emails. We'll certainly never share your email address or contact information with anyone else.
Bottom line
We've purposefully created very few opportunities for you to give us information about yourself. Any information we do receive from you will not be sold or rented to others. If your information needs to be shared with service providers (for email distribution, for example), we make sure those partners have rigorous information protection policies in place.
