How do I save calculations in Nexus Calc?
After performing a calculation, tap the "Save" button and give it a custom name. You can then
access all saved calculations from the history tab and even use them as variables in new
expressions.
How do I use saved calculations in new expressions?
Simply type the name of your saved calculation in a new expression. For example, if you saved
"monthly_expenses" as 1500, you can create a new calculation with "salary - monthly_expenses" to
calculate your remaining balance.
Are my calculations synced across devices?
Yes! When you sign in with your account, all your calculations are automatically synced across
all your devices. You can access them from your phone, tablet, or any other device where you're
signed in.
How accurate are the currency conversion rates?
Our currency converter uses real-time rates from Open Exchange Rates, which are updated hourly.
This ensures you always have the most current and accurate conversion rates available.
Can I use Nexus Calc offline?
Yes! All calculator functions work offline. Currency conversion requires an internet connection,
but all other features including unit conversion and calculation history work perfectly without
internet.
How do I delete my account and data?
You can delete your account from the app settings. This will permanently remove all your data
including saved calculations and sync history. Please note that this action cannot be undone.
What authentication methods are supported?
Nexus Calc supports multiple authentication methods including anonymous login, email/password,
Google Sign-In, and Apple Sign-In (on iOS). Choose the method that works best for you.
Is my data secure and private?
Absolutely! We use Firebase's secure infrastructure with end-to-end encryption. Your data is
only accessible to you, and we never share or sell your personal information or calculations.
