Privacy Policy
Last updated 11 November 2026
Calcwise is a financial calculator. Every calculation happens on your iPhone or iPad. The amounts, rates and names you type never leave your device. Calcwise has no account and shows no ads.
Anonymous usage counts
Calcwise counts how the app is used with TelemetryDeck (TelemetryDeck GmbH, Germany), so we can see which calculators people use and what to improve. A count says things like "a loan calculator was opened", "a schedule was viewed" or "the currency was changed to INR", together with the app version, device model, iOS version, language, region and text-size setting.
A count never contains an amount, rate, result, name, search text or anything you typed. Each device is identified only by a random value that TelemetryDeck hashes twice, so it can't be traced back to you. Counts are not linked to you, not used for advertising and not shared with anyone else.
Crash reports
If the App Store or TestFlight version of Calcwise crashes or stops responding, it sends a crash report to Sentry (Functional Software, Inc.), so the problem can be found and fixed. A report contains the technical details of the crash: the app version, the code that was running, the device model, iOS version, free memory and similar device state, and a random install identifier.
A report does not contain your name, email, the amounts or names you typed, screenshots or a recording of the screen. IP addresses are not stored. Reports are not linked to you, not used for advertising and not shared with anyone else.
What is stored on your device
- What you last typed in each calculator, so it is there when you come back.
- Your favourites and settings (currency, country schemes, decimals, theme).
This stays on the device and is not synced to iCloud. Deleting the app deletes it.
What Calcwise does not do
- No account or sign-in.
- No advertising and no tracking across apps or websites.
- No access to your contacts, photos, location, camera or microphone.
- No saving or uploading of calculations.
Children
Calcwise is a general-audience calculator. It collects no personal information from anyone, including children.
Changes
If this policy changes, the new version will be posted here with a new date.
