Get Help

Email support@dynocalc.com. Include the calculator or feature name, your device, and the steps that caused the problem. Remove personal or financial details from screenshots before sending them.

Close and reopen the app, then check the App Store for an update. If the problem continues, restart your device and send a support request with your iPhone model, iOS version, and a description of where the app stops responding.

Send us the calculator name, the inputs you entered, the result you received, and the result you expected. Remove names, account numbers, and other sensitive information. DynoCalc results are estimates, so confirm important financial, tax, legal, medical, and safety decisions with a qualified professional or official source.

Check your internet connection and reopen the calculator. Live tools may show cached or fallback data when a data provider is delayed or unavailable. Check the status and update time shown in the calculator, then contact us if it remains stale.

Open DynoCalc Settings and choose Restore Purchases. Make sure you are signed in with the Apple Account used for the original purchase. Apple processes App Store billing, so DynoCalc support cannot view or change your payment information.

Confirm that iCloud sync is enabled in DynoCalc and that both devices use the same Apple Account. Keep both devices connected to the internet and allow time for iCloud to sync. If the data still does not appear, contact us before deleting or reinstalling the app.

DynoCalc processes calculator inputs on your device or in your browser. DynoCalc does not intentionally send calculator input values as analytics events. Read the Privacy Policy for details about analytics, advertising, and contact requests.

Send a support request with the page URL, your browser and device, and the steps that caused the issue. Tell us what you expected to see and what appeared instead.
