Continuity commitment
Last updated: 2 August 2026
The question this answers. "We are paying for a year. What happens if a supplier of yours fails — or if you stop?" It is a fair question to ask a small provider, and it deserves a written answer rather than reassurance.
If a supplier of ours fails
The games keep working. They are static pages that run entirely in the browser; they do not call a server to play. Concretely:
- Our measurement provider fails — anonymous usage statistics stop being collected. No effect on play, on assignments or on licences.
- Our payment provider fails — new licences cannot be bought until it is replaced. Existing licence keys continue to work; they are validated without contacting a server.
- Our advertising provider fails — no effect on paid or educational use, which is advertising-free by design.
If we discontinue the service
- At least 90 days' notice, sent to the contact address on the licence and published on all three sites. Ninety days is chosen so that no school is left without notice in the middle of a term.
- Proportional refund of the unused part of any paid licence period.
- The written material stays available. The guides, lesson plans, handbooks and rubrics are released under a free licence (Creative Commons Attribution–ShareAlike 4.0), so that work built on them does not disappear with us. They are already maintained in a public repository.
What this does not cover
We do not commit to transferring the games' source code or brand. The commitment is about continuity of the material you and your students rely on, and about not leaving a paid customer stranded mid-term.
Relationship to the Terms of Use
Where the general Terms of Use reserve the right to discontinue the service at any time, this commitment takes precedence for paid licences, together with the service level commitment.
