Using liveCalc

Updated: 3 October 2026

Calculation results

liveCalc is a general calculation and note-taking tool. Input mistakes, rounding, unit choices or software errors can affect results. Independently verify important results, especially before using them for safety-critical, financial, medical, legal or technical decisions.

Currencies

Currency conversions require an explicit exchange-rate formula. On request, liveCalc downloads dated reference rates from the European Central Bank (ECB) and stores them for offline use. When inserted into a notebook, the rate, date and source are recorded; later updates do not change that formula. ECB reference rates are informational, not executable transaction rates. Check the rate date and use your own rate when needed.

Documents and backups

You are responsible for backing up important notebooks. Export them before deleting the app or resetting a device.
