Terms of Service

These Terms of Service ("Terms") govern your use of Ekuation ("Ekuation", "we", "us", "our") and the calculator tools, AI features, and related services we provide (the "Service"). By using Ekuation, you agree to these Terms.

The short version: use our calculators for good, don't abuse the service, and remember that calculator results are for informational purposes only — not professional advice.

Ekuation is a free online calculator platform. We provide calculators for finance, health, mathematics, and everyday life, along with optional features like saved profiles and AI-powered explanations.

You do not need an account to use our calculators. If you choose to create one:

• You are responsible for keeping your login credentials secure.
• You must provide accurate information when signing up.
• You may delete your account at any time from your account settings.

We may suspend or terminate accounts that violate these Terms.

You agree not to:

• Use the Service for any unlawful purpose.
• Attempt to disrupt, overload, or interfere with the Service.
• Scrape or bulk-download content from the Service without our permission.
• Use automated tools to access the Service in a way that exceeds reasonable usage.
• Submit harmful content, spam, or malicious code through any feature that accepts user input (such as the AI chat).

Our calculators are tools for informational and educational purposes only. Results should not be treated as professional advice. Specifically:

• Health calculators (BMI, calories, etc.) are not a substitute for medical advice. Always consult a healthcare professional for health decisions.
• Finance calculators (loans, mortgages, taxes, etc.) are not a substitute for financial, tax, or legal advice. Consult a qualified professional for financial decisions.
• Math calculators are provided as learning aids. Always verify critical calculations independently.

We do our best to ensure accuracy, but we make no guarantees that results are error-free.

Some calculators include an optional AI chat that explains results. AI responses are generated by a language model and may contain errors. Do not rely on AI responses as authoritative advice.

If you save calculator profiles (age, weight, preferences, etc.), that data is stored securely and used solely to improve your experience. See our Privacy Policy for full details on how we handle your data.

All content on Ekuation — including text, graphics, calculator logic, code, and design — is owned by us or our licensors and is protected by copyright and other intellectual property laws.

You may use the Service for personal, non-commercial purposes. You may not reproduce, distribute, or create derivative works from our content without our written permission.

Ekuation may display advertisements provided by third-party ad networks. We are not responsible for the content of those ads. Interacting with an ad is at your own risk and subject to the advertiser's terms.

We aim to keep Ekuation available and reliable, but we do not guarantee uninterrupted access. We may modify, suspend, or discontinue any part of the Service at any time without notice.

We may also update these Terms from time to time. When we do, we will update the date at the top. Continued use of the Service after changes means you accept the updated Terms.

To the maximum extent permitted by law:

• The Service is provided "as is" and "as available" without warranties of any kind, whether express or implied.
• We are not liable for any damages arising from your use of (or inability to use) the Service, including but not limited to decisions made based on calculator results or AI responses.
• Our total liability to you for any claim related to the Service shall not exceed the amount you paid us in the twelve months preceding the claim (which, for a free service, is zero).

These Terms are governed by the laws of France, without regard to conflict of law principles. Any disputes shall be resolved exclusively in the courts of France.
