Terms of Service

1. Accepting the terms

By using Schackappen you accept these terms of service. If you do not accept the terms, you should not use the app.

2. Who may use the app?

Schackappen is aimed at:

• Schools and education
• Chess clubs and associations
• Families and individuals

Students log in with a class code from their teacher. Children under 13 should use the app with a parent or teacher present.

3. Cost

Schackappen is a subscription service. Schools and associations pay a flat monthly price with an unlimited number of students; families pay a lower monthly price. New customers get a free 30-day trial with no commitment, and you can cancel at any time. Current prices are on our pricing page.

4. How the app may be used

You may:

• Use the app for personal and educational purposes
• Share the link to the app freely
• Install the app on your devices

You may not:

• Copy, modify or distribute the app's code without permission
• Use the app to create a competing service
• Exploit any security flaws or attempt to hack the app
• Resell, rent out or sub-license access to the app without an agreement with us

5. Intellectual property

All design, code and original content in Schackappen is owned by the developer. Some components come from third parties and are used under their respective licences:

• The chess pieces (the cburnett set) — Creative Commons CC BY-SA 3.0, via Wikimedia Commons.
• The chess library chess.js v0.10.3 © Jeff Hlywa — licensed under BSD 2-Clause.
• The chess engine Stockfish — licensed under GNU GPL v3.
• The typefaces Crimson Pro and Inter — SIL Open Font License.

6. Limitation of liability

Schackappen is provided "as is". We make no guarantees that:

• The app is always available without interruption
• The content is entirely free of errors
• The app is fit for a specific purpose

The developer is not liable for any damages arising from use of the app, directly or indirectly.

7. Data and privacy

See our separate Privacy Policy for how data is handled. In short: we apply data minimisation and store data within the EU — for students we only store first name and avatar.

8. Changes to the terms

We may update these terms if needed. Significant changes will be announced on the start page. Continued use after changes means you accept the new terms.

9. Cancellation

You can cancel your subscription at any time; it then does not renew after the current billing period. We may change or stop offering the service, and will give reasonable notice if we do.

10. Applicable law

These terms are governed by Swedish law. Disputes are to be resolved primarily through dialogue; failing that, by a Swedish court.
