SunArch Pro: free trial and cancellation

SunArch Pro is an auto-renewable subscription (weekly or monthly). When a free trial is offered, you are charged only after it ends. To cancel, go to Settings → [your name] → Subscriptions → SunArch at least 24 hours before the trial or period ends. Deleting the app doesn't cancel the subscription.

Restore purchases

On a new iPhone, or after reinstalling, open the subscription screen in SunArch and tap Restore purchases, signed in with the same Apple Account.

Location

SunArch needs your location to calculate the sun where you are. If you denied it, go to Settings → Privacy & Security → Location Services → SunArch → While Using the App.

Compass, Sun AR and Facade AR

The overlays use the iPhone compass. If the drawing doesn't line up with the real sun, move the iPhone in a figure-eight to calibrate it, stay away from metal and magnets, or use Align with the sun in Sun AR.

iCloud sync

Saved solar sites sync through your private iCloud. Check that you are signed in to iCloud and that SunArch is turned on in Settings → [your name] → iCloud.

About the numbers

Sun positions come from NOAA's solar equations. Solar energy figures are estimates from the PVEducation clear-sky model and NASA POWER climate averages, labeled as estimates in the app. They are not a substitute for a professional project.
