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 Schackappen.

2. Who may use Schackappen?

Schackappen is aimed at:

• Schools and education
• Chess clubs and associations

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

3. Cost

Schackappen is a subscription service for schools and associations: a flat price for an unlimited number of students, billed once a year. New customers get a free 14-day trial with no commitment. The subscription renews one year at a time, and we remind you in good time before each renewal. You can cancel at any time — access then runs to the end of the current period. Current prices are on our pricing page.

4. How Schackappen may be used

You may:

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

You may not:

• Copy, modify or distribute Schackappen's code without permission
• Use Schackappen to create a competing service
• Exploit any security flaws or attempt to hack Schackappen
• Resell, rent out or sub-license access to Schackappen 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:

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

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

7. Data and privacy

See our separate Privacy Policy and our data processing agreement (DPA) 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

The subscription renews automatically one year at a time. We remind you in good time before each renewal so it never happens unexpectedly. You can cancel at any time; the subscription then does not renew and access runs to the end of 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.
