Common questions
Quick Solutions for Common Issues
App crashes or will not open
Update the app to the latest version via the App Store or Google Play. If the issue persists, please email us your device model, OS version, and the steps to reproduce the crash.
Restoring purchases
Open the app's Settings menu and tap "Restore Purchases," ensuring you are signed into the store account used for the original purchase.
Canceling a subscription
Subscriptions are managed directly by Apple or Google, not CS Group. You can cancel your subscription through your App Store or Google Play account settings. Note: Deleting the app does not automatically cancel your subscription.
In-app purchase refunds
Refund requests are processed directly by Apple or Google according to their respective store policies. CS Group cannot issue direct refunds for store transactions.
Managing personalized ads
You can adjust ad preferences in your device's system privacy settings. For users in the EEA, UK, and Switzerland, ad settings can also be updated directly within the app.
Account and data deletion
Please follow the instructions on our Data Deletion Request page, or email us with the app name and your registered account details.
Marketplace storefront orders
Please contact us directly through Amazon, Etsy, or Walmart buyer messaging to ensure coverage under the platform's buyer protection policies. Email us directly only if the marketplace cannot resolve your request.
