Terms and Conditions

These terms cover the basics of using Numifylab. It's a small site run by one person, and these terms are written to be actually readable rather than padded out with boilerplate you'll skim past. By using this site, you're agreeing to what's below.

1. What Numifylab is

Numifylab is a free collection of online calculators and developer tools. There's no account system, no paid tier, and nothing you need to sign up for. You use a tool, you get a result, that's the whole interaction.

2. Using the site

You're welcome to use any calculator on this site for personal, academic, or professional purposes. Please don't:

• Attempt to scrape, copy, or republish the site's content or code wholesale as your own
• Try to disrupt the site's operation (automated abuse, excessive scraping, attempts to break the tools)
• Use the site for anything illegal under the laws that apply to you

3. Accuracy of results

Verify any result independently before relying on it for a financial, medical, academic, legal, or otherwise consequential decision, and talk to a qualified professional where that's appropriate. This is covered in more detail in the Privacy Policy.

4. No warranty

Numifylab is provided "as is," without warranty of any kind, express or implied. I don't guarantee the site will be available at all times, free of errors, or uninterrupted — it's maintained by one person, and things occasionally break or go down for maintenance.

5. Limitation of liability

To the fullest extent permitted by law, Numifylab and its operator aren't liable for any loss, damage, or consequence — direct or indirect — arising from your use of, or inability to use, this site or any calculator on it.

6. Advertising

This site is supported by advertising through Google AdSense. Ads are served by Google and its partners, not chosen individually by Numifylab, and their presence doesn't constitute an endorsement of any advertiser or product. See the Privacy Policy for how AdSense uses cookies.

7. Intellectual property

The design, code, written explanations, and branding of Numifylab belong to its operator. You're welcome to link to any page on this site freely. If you'd like to use content from this site elsewhere beyond a simple link, reach out via the contact page first.

8. Changes to these terms

These terms may be updated occasionally — for new features, legal requirements, or just clearer wording. The "Last updated" date at the top will always reflect the most recent revision. Continuing to use the site after a change means you accept the updated terms.

9. Contact

Questions about these terms are welcome any time via the contact page.
