20. Consumer Rights

Nothing in these Terms limits rights that cannot be waived under applicable consumer protection law.

If a term conflicts with mandatory consumer law, the mandatory law controls.

21. Governing Law

Unless mandatory law in your country provides otherwise, these Terms are governed by the laws of Israel, without regard to conflict-of-law rules.

If MathbookLM is operated by a US entity or another registered entity, this section should be updated to match that entity’s governing law.

22. Dispute Resolution

22.1 Informal Resolution

Before filing a legal claim, you agree to contact legal@mathbooklm.com with:

• your name and account email;
• a description of the dispute;
• the relief requested.

We will attempt to resolve the dispute informally within 30 days.

For users outside jurisdictions with mandatory local venue rights, disputes will be brought in the competent courts of Israel.

EU, UK, Israeli, and other consumers may have the right to bring claims in their local courts where mandatory law provides.

22.3 Arbitration for US Users

For users in the United States only, and where enforceable, disputes may be resolved through binding individual arbitration if MathbookLM publishes an arbitration procedure or incorporates one into these Terms.

No class actions or representative proceedings are permitted to the extent allowed by law.

If arbitration is not enforceable, disputes may proceed in court.

We may update these Terms from time to time.

For material changes, we will provide notice through the Service, by email, or by another reasonable method.

If required by law, we will request consent.

Continued use after changes become effective means you accept the updated Terms.

25. Severability

If any provision is found invalid or unenforceable, the remaining provisions remain in effect.

26. Assignment

You may not assign these Terms without our written consent.

We may assign these Terms in connection with a merger, acquisition, financing, reorganization, sale of assets, or operation of law.
