Effective August 15, 2026
CasCalc collects nothing. It has no accounts, no analytics, no advertising, and makes no network requests. Everything you enter stays on your device.
None. CasCalc does not collect, store, or transmit any personal information. There is no sign-up, no login, and no way for us to identify you or link any activity to you.
CasCalc saves your work locally so it is there when you come back:
This is written to your device's own storage and is never sent anywhere. It may be included in your personal iPhone backup, because that backup covers app data generally — that backup belongs to you and is governed by Apple's terms, not ours. Deleting CasCalc removes all of it.
CasCalc makes no network requests of its own. It performs every calculation on your device and works fully offline. If you tap the support email address, iOS opens your mail app with a new message — nothing is sent unless you send it yourself.
There are none. CasCalc contains no analytics frameworks, no advertising SDKs, no crash reporters, and no tracking of any kind. It does not request or use the advertising identifier, and it does not track you across apps or websites.
CasCalc is safe for users of any age. Because it collects no data at all, it collects no data from children.
CasCalc is a one-time purchase with no in-app purchases or subscriptions. Your payment is handled entirely by Apple; we never see your payment details. Apple may give us anonymous, aggregated sales and download figures, which cannot identify individual users.
If this policy changes, the revised version will be posted on this page with a new effective date.
