Help with Calculator 365
Answers about calculator modes, history, Pro features and your privacy choices.
Where do I find the different calculators?
Open the mode selector in the app. In addition to the standard calculator, there are views for scientific functions, finance, units and time spans. Each extended mode includes three free successful calculation chains per local day. Opening a mode does not use an allowance. Active Pro removes this daily limit; some existing users may retain a one-time bonus from earlier free uses.
What does AC do, and where is history?
AC resets the current calculation. Saved calculations remain in history. There you can reuse a result and delete individual entries or clear the entire history.
Why can I see only part of my history?
The free view shows the latest entries. Pro unlocks the full history view and additional export and copy functions. The app limits the total number stored; history is not a permanent archive.
What happens when I share or copy?
The app passes the selected calculation or exported history to the clipboard or to the app you choose. Check the content before sharing it. The receiving application is responsible for its subsequent processing.
Which Pro offers are planned?
The app is configured for a yearly subscription and a one-time Lifetime purchase. Only the features, prices, periods and renewal terms shown by the relevant store and its confirmation dialog at purchase time are binding. This website does not yet promise public purchase availability.
How do I restore an existing purchase?
Use the restore function in the Pro area with the same store account used for the purchase. The relevant store must be reachable. Apple and Google Play purchases are checked through their respective stores; transfer between stores is not promised. If a purchase is not recognised, send the app version and error message by email to our support team, without payment details.
How do I cancel a subscription?
Manage and cancel the subscription in the subscription settings of the Apple or Google Play account used to purchase it. Deleting the app does not cancel a subscription. A one-time Lifetime purchase has no recurring subscription renewal.
Do I have to watch advertising videos?
Advertising videos are an optional way to obtain additional Smart Input uses. Banners and automatically displayed full-screen ads are disabled in the reviewed app configuration. Video availability depends, among other things, on your privacy choices, connection and advertising provider.
Where can I change advertising privacy choices?
When Google's consent management requires or makes a new choice available, an advertising privacy entry appears under About in the app settings. You can reopen the dialog there. An advertising choice does not replace any required iOS tracking permission or separate consent for other analytics.
Does the calculator work offline?
Calculations and access to locally stored settings and history do not themselves require a network connection. Store purchases, restoration, advertising videos and opening external help pages require a connection.
How can I remove saved data?
Delete individual calculations or clear history in the app. Other settings and usage counters are held in local app storage. Operating-system backups can also contain data; manage them through your device settings. Uninstalling neither cancels store subscriptions nor automatically deletes records held by stores or external providers.
A result seems unexpected. What should I check?
Check the selected mode, brackets, signs, percentage basis, rounding and the angle unit for trigonometric calculations. Independently verify important results. Financial and tax calculations are calculation aids and do not replace individual professional advice.
