Terms of Use — Solfun

The service

Solfun is a music-reading learning app published by Shadowlink Digital. It is free for children, funded by advertising, with two paid options.

"No ads"

One-time, non-consumable purchase: it removes ads for good, on every device linked to the same App Store or Google Play account. Use "Restore purchases" on a new device.

Teacher subscription

Auto-renewing subscription, monthly or yearly. Payment is charged to your App Store or Google Play account at confirmation of purchase.

The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. Your account is charged for renewal within the 24 hours before the end of the period.

You manage and cancel the subscription from your store account settings. Any unused portion of a free trial is forfeited when you subscribe.

If the subscription ends, your classes and your students' stars are kept on the device; managing them resumes as soon as you subscribe again.

Your data

Data is stored on your device. Remember to export a backup: we cannot recover erased data or a lost device.

Liability

The educational content is provided as is, as a learning aid. It does not replace the teacher.
