Support the Rechenkiste

Free – and it stays that way

The Rechenkiste is a project by PixelDevIO, run by me, Daniel Fiebich. All worksheets, templates and answers are free, without sign-up, without adverts and without tracking. That will not change – not even for everyone who gives nothing.

What your support means

With a coffee you say thank you and show me that the Rechenkiste is needed. That helps me keep at it and keep developing it.

Buy me a coffee

Via Ko-fi you can give an amount of your choice once – also with PayPal. Thank you!

Support via Ko-fi

Support is voluntary and nothing is given in return. It is not a tax-deductible donation, because PixelDevIO is not a charity. The payment goes through ko-fi.com; their privacy policy applies there. The Rechenkiste itself loads nothing from Ko-fi unless you click the button.

Freiwillige Schullizenz

Auch Schulen können die Rechenkiste grundsätzlich kostenfrei nutzen. Mit einer freiwilligen Förderlizenz personalisieren sie ihre Materialien mit Schulname und Logo und unterstützen zugleich meine Arbeit an der Rechenkiste und weiteren Projekten.

A big help even without money
