PRICING FAQ
Does the trial auto-charge?
Pro’s first subscription includes a 7-day free trial. Cancel in iOS Settings during the trial and pay nothing; billing starts only after it ends.
How do I cancel?
iOS Settings → Apple ID → Subscriptions, anytime. Features stay active until the paid period ends.
Will Free stay free?
Yes. 3 addresses, push alerts and Time Sensitive critical alerts (once you allow them in iOS settings) are the product baseline — never paywalled.
