Frequently asked questions

Is GlassCalc Pro a subscription?

No. Pro is a one-time purchase that you keep forever, and it works with Family Sharing. There are no subscriptions and no ads. Features that are free today stay free.

How do I restore my purchase?

Open Settings in GlassCalc and tap “Restore Purchases”. Make sure you are signed in with the same Apple Account you used to buy Pro.

How do I edit a calculation in my history?

Tap a number or operator in the tape above the keypad, change it and confirm. Every later line that uses the result recalculates. You can undo the whole change in one step.

Why does the app use a comma as the decimal separator?

Number formats follow your region in iOS Settings, not the app language. You can override the decimal and grouping separators in GlassCalc Settings.

Where do exchange rates come from?

Reference rates from the European Central Bank and a second public source for other currencies. The app includes a snapshot of these rates, so it works offline, and the converter shows the date of the rates. Rates are for reference only; banks and exchange offices use their own rates, so you can also enter a custom rate. Sources are listed in Settings › About.

How do I turn off usage statistics?

In GlassCalc Settings, turn off “Share anonymous usage statistics”. See the privacy policy for details.

How do I delete my data?

Delete individual entries with a swipe, or clear a page. Deleting the app removes all data on the device.
