Not medical advice

Subscriptions and purchases

Sipcurve Pro is available as a yearly subscription with a free trial or as a one-time lifetime purchase. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. You can manage or cancel subscriptions in your device settings. Any unused portion of a free trial is forfeited when you purchase a subscription.

Your data

Your data is stored on your device. You are responsible for backups, for example by exporting a CSV file from Settings.

Changes

We may update the app and these terms. Continued use after an update means you accept the updated terms.
