Tell us what went wrong. We will help.
Support for Chalkline, Daypart, Carshoots, and every other Lumen iPhone app is available by email.
Contact support
Include the app name, your iOS version, what you expected, and what appeared instead. Do not send passwords, payment details, or private source material.
Purchases and subscriptions
Use Restore Purchases on the app's purchase screen if an active Apple subscription is not recognized. You can manage or cancel subscriptions in iPhone Settings under your Apple Account. Billing is handled by Apple; we cannot view your payment card.
AI requests
If a generation fails, try again on a stable connection. Failed requests are not counted against the in-app allowance. For requests involving a photograph, recording, or document, the app shows what will be sent before upload.
Privacy
Read the Lumen Apps Privacy Policy. For Apple's standard subscription terms, read the Terms of Use.
