Numera — questions & support

If your question is not here, the contact page reaches me directly.

Is Numera free?

Yes, completely — no ads, no in-app purchases, no subscription.

Does it work offline?

Yes. Everything except fetching new currency rates runs on device. Rates are cached and refresh the next time you are online; the rate date is shown so you always know how current they are.

Where do the rates come from?

The European Central Bank, via the Frankfurter API. No identifiers are sent with the request.

Is there an iPad or Android version?

Not currently. Numera is designed for iPhone, and I would rather keep one version good than three versions adequate.

How do I report a bug?

Through the contact page. Tell me your iPhone model and iOS version if you can — it usually halves the time to a fix.

What data does Numera collect?

None. See the privacy policy for the full detail — it is short.
