I cannot select photos or open the camera.
Open iPhone Settings, choose Apps → NAILU, and check photo and camera permissions. If access is limited to selected photos, add the photo you want to use. Restart the app if needed.
AI generation is stuck or shows an error.
Check your internet connection, wait for any current request to finish, and update or restart the app. Try a bright, sharp hand photo. If the problem continues, email the error, time, device, iOS and app version.
How do I cancel my subscription?
On iPhone, open Settings → your name → Subscriptions → NAILU, then cancel the subscription. Deleting the app or account does not cancel billing. Check the purchase screen for renewal and trial conditions.
How do I restore a purchase or request a refund?
Use the Apple Account used for the purchase, and use Restore Purchases in the app if available. Contact support if access is missing. App Store refunds can be requested at reportaproblem.apple.com and are subject to Apple’s review.
How can I delete my account and data?
Open the app’s Settings or Account section and use the deletion option if available. Otherwise email privacy@nailu.jp with “NAILU account deletion”, the app name and your registered email or username. After identity verification, we process deletion and confirm by email. Deletion is permanent. Save any images first and cancel subscriptions separately. Never send your password.
