Per-app legal pages

Privacy and terms are written per product so permissions and data practices match what each app actually does.

How do I contact support?

Email [email protected] or visit our Support page. Include the app name, device model, iOS or Android version, and a short description of the issue.

Where are Privacy Policy and Terms?

Each app page links to its own Privacy Policy and Terms of Use. You can also start from our Legal centre.

How do subscriptions and refunds work?

Apple or Google is the seller of record depending on the store. Manage or cancel subscriptions in App Store subscriptions or Google Play Payments & subscriptions. Refund requests within each store’s windows follow that store’s policy; after that, contact us with your order details.

How can I request data deletion?

See our Data deletion page. Uninstalling an app removes local data on the device. Email us for any server-side or account-related deletion requests.
