CalcHub is a fully free application. There are no registration forms, in-app purchases, hidden premiums, or subscriptions required. Should in-app purchases or subscription options be added in future updates, all payments, billing, and refund requests will be managed strictly and securely through Apple Media Services billing platforms in compliance with App Store rules.
Your privacy is important. To clear all historical inputs and answers, open the Scientific Calculator, tap the clock history icon on the top right, scroll to the bottom of the list sheet, and tap the red "Clear History" button. This permanently deletes the SwiftData database logs from your device.
No. CalcHub runs entirely offline. All calculations and history entries are saved locally in standard iOS secure app directories. We do not transmit or back up any metrics to cloud servers.
