Contact us (for parents and guardians)

Email: support@ccode.fi. We aim to reply within five business days in Finnish or English. Please have a parent or guardian send support messages and do not include personal details about a child. Include your device model, operating system version, and app version.

FAQ: selecting tables and sibling profiles

On the Play tab, you can select one or more multiplication tables (1–10) to practise at a time. On the Skills tab, siblings can create separate local player profiles with a nickname and animal avatar so stars, rewards, and mastery maps stay separate for each child.

FAQ: offline use and sound effects

Helmi runs completely on the device without an internet connection. Sound effects can be muted or unmuted from the top bar or the Skills tab, and the setting is saved locally on the device.

FAQ: resetting and deleting data

All player profiles, stars, rewards, and practice history are stored only on your own phone or tablet. You can reset a player's progress on the Skills tab or delete all data by uninstalling the app from the device.
