Everything local about the teacher area stays free forever — a PIN-protected class, homework, recital notes, CSV export, archive. Only ONE thing is paid: connecting several devices through the server.
Try it for free, before anyone pays
"Bring class online" works from the start, even without an ordered licence — children and parents can join, the remote overview runs. Klavissimo never hard-cuts a class; it generously stays usable until the licence is entered, and after it ends.
€49 per teacher for 12 months — buy or order in the browser only
As an individual teacher, you buy the licence on the pricing page with "Buy class licence" (payment via Stripe). The redemption code arrives by email right after payment, the invoice in a second email. For a school or several teachers there is the order form (school/institution, invoice address, number of teachers, your email, optional contact person and message) opens your own mail program on submit, with a prefilled message to hallo@klavissimo.app — no form server, no data stored on the website. The button live-updates the total (number × €49, incl. 20% Austrian VAT); the site promises the licence and invoice will reach your school office within two working days.
Redeeming — the code from your email
The code email after buying online, or the invoice email after an order, brings a redeem code in the format "KLS-XXXX-XXXX-XXXX-XXXX". In the teacher area, in the class overview, you enter it in the "Redeem code" field — right after that, the line "Licence until {date}" appears, no detour through Klaus. Prerequisite: the class must already be online, otherwise there is nothing server-side for the licence to attach to. A guest or substitute without full class rights cannot redeem the code.
One code for all your classes
The licence is per teacher. When you redeem the code in one class, it also covers your other classes that are already online on this device. If you bring another class online later, enter the same code there once more. Submitting the same code twice is not an error; nothing happens twice. If the code already belongs to another teacher, the app reports "This code is already redeemed." There is no automatic renewal: the licence runs for 12 months; after that you buy or order again and get a new code.
Good to know:
"Only connecting several devices is paid, deliberately kept well under school-budget thresholds." Neither setting up a class locally nor trying out the connection requires a licence.
Your data:
A lost code can't be shown again — we never store it in plain text, only a hash. Write to us and the operator issues a new code; the old one is invalidated in the process.

It describes features that are not part of this app. Everything the app can do is open to you without any setup.
