Tell us the affected screen and reproduction steps. Do not send original pet or child photos, sticker files, payment credentials, or sensitive information.
This document reflects the services and platform behavior currently provided.
Before you contact us
Include iOS or Apps-in-Toss, device model, operating system, app version, affected screen, and steps. If a screenshot is essential, redact names, photos, order numbers, and other personal information first.
Photo and sticker issues
Check photo permission and free storage, then try another photo. If automatic cutout fails, use the manual editor. The original photo is not needed in your support email.
Ads and privacy choices
On iOS, check the network and consent state if an ad does not load. The privacy-choice form can be reopened in Settings. If an ad appears after purchase, try Restore Purchases first.
Purchases, restore, and refunds
Apple or the platform that actually sold the item handles payment and refunds. Never send card information or account passwords. Send only the restore result and the error state shown by the app.
Data deletion and support records
Delete local data from app Settings. Images exported to Photos or another location must be deleted separately.
Ordinary support enquiries are kept for one year after closure. Purchase, refund, or dispute records are kept for three years unless law requires longer. Email hello@mmche.studio to request access, correction, or deletion.
