Sunstead has no accounts, no login and no servers of our own. We cannot see who you are, and we do not want to.
If you grant location access, Sunstead uses your coordinates to work out the sunset time, the compass bearing of the setting sun, golden hour and blue hour, and which mapped city is nearest. All of that is calculated on your device. Your location is not stored on any server we control, because we do not operate one.
There is one exception you should know about. To show you tonight's sky forecast, the app sends your latitude and longitude to Open-Meteo, a weather data service, to retrieve cloud cover for your area. This request includes your coordinates and your time zone. It includes no name, no email, no device identifier and no advertising ID, and it is not tied to any profile. Open-Meteo handles that request under its own privacy policy.
You can decline location access. The app still works — you can browse mapped cities and their alignment dates without it.
Sunstead records a small number of anonymous events so we can tell which parts of the app are useful and where people get stuck. These are processed by PostHog on servers in the United States.
| What is sent | What is not sent |
|---|---|
|
A random ID generated on first launch Which screen was shown Whether a permission was granted or declined Answers to onboarding questions App version and operating system |
Your coordinates or any location City, spot or place names Your name, email or phone number Your device ID or advertising ID Anything you could be identified by |
The random ID identifies an installation, not a person. It is not derived from anything about you or your device, it is not shared with anyone, and deleting the app destroys it permanently. Reinstalling produces a new one that cannot be connected to the old one.
If you switch on alerts, they are scheduled and delivered by your own device. Alignment dates are already stored in the app, so nothing needs to be sent anywhere to remind you about them. We do not operate a push server and we never receive a record of what you were alerted about.
Subscriptions are sold and processed by Apple through the App Store. Apple tells the app whether an active subscription exists. We never see your payment details, card number or billing address. Apple's handling of that information is covered by Apple's Privacy Policy.
Saved spots, your alert preferences, your onboarding answers and your subscription status are kept locally on your phone. Deleting the app removes all of it.
Sunstead is not directed at children under 13, and we do not knowingly collect information from them. Since we collect no personal information from anyone, we hold none belonging to a child.
Depending on where you live, you may have the right to access, correct or delete personal information held about you. In practice we hold none: there is no account to look up and nothing that identifies you. If you want the anonymous usage events from your installation deleted, email us from the support page and we will remove them — you will need to send us the random ID, which the app can show you.
If this policy changes in a way that affects what we collect, we will update the date at the top of this page and describe the change here.
