By creating an account or using 1calculator (the “Service”), you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.

You are responsible for your account and for keeping your credentials secure. You must provide accurate information and be old enough to form a binding contract in your jurisdiction.
3. Your content & licence
You retain ownership of the calculators and content you create. By publishing publicly, you grant 1calculator a worldwide, non-exclusive, royalty-free licence to host, display, distribute and promote that content as part of operating the Service (including the public library and embeds). You are responsible for ensuring you have the rights to anything you publish.
4. Acceptable use
Do not use the Service to publish unlawful, harmful, deceptive, infringing or spam content, to attempt to break security or formulas, or to misuse other people’s data. We may remove content and suspend accounts that breach these Terms.
5. Calculators are not professional advice
Calculators on the Service are provided “as is” for general information. They are not financial, medical, legal, engineering or other professional advice. Verify important results independently; we are not liable for decisions made based on a calculator’s output.
6. Intellectual property
The 1calculator name, brand and software are owned by us. These Terms do not grant you rights to our trademarks.

You may stop using the Service at any time and delete your account from your settings. We may suspend or terminate access for breach of these Terms.
8. Disclaimers & liability
To the maximum extent permitted by law, the Service is provided without warranties, and we are not liable for indirect or consequential losses. Nothing in these Terms limits liability that cannot be limited by law.
9. Changes
We may update these Terms; material changes will be reflected by the “last updated” date. Continued use after changes means you accept them.
