Terms of use

Last updated: October 3, 2026

The short version

Every question on Fourtile is free. The answers are estimates based on the numbers you type. They are not financial, tax or legal advice.

Who we are

Fourtile is run by Diyar Saadullah. The full contact details are on the Privacy page, and you can write to hello@fourtilehq.com anytime.

Using the calculators

  • They are free, with no account and no sign-up.
  • Each answer comes from the numbers you type and the simple rules shown on its page, for example a fixed rate and the same payment every month. Real life can differ: rates change, fees apply, payments vary.
  • The answers are estimates to help you plan. They are not financial, tax or legal advice. For a loan, taxes or a big decision, talk to a professional where you live.

No guarantee

We check our calculations carefully and fix any mistake as soon as we know about it. The site is provided as it is: we cannot promise that the site is always available, free of errors, or right for your situation. If you find a mistake, please tell us at hello@fourtilehq.com.

Liability

Use the answers as a guide, not as a promise. As far as the law allows, Fourtile is not liable for decisions you make, or losses you have, based on them. Nothing here limits liability where the law does not allow it, for example for intent or gross negligence.

Fair use

Use the site for your own needs. Do not try to break it, overload it or copy it as a whole. You are welcome to share links to it and your own results.

Name and content

The Fourtile name, logo, texts and design belong to Fourtile.

Links to other sites

Our links to YouTube and Pinterest lead to services we do not control. Their own terms apply there.

Changes

If these terms change, the date at the top changes with it. No silent edits.

Your rights as a consumer

Nothing in these terms takes away the rights you have as a consumer under the law of the country where you live.

Law

These terms are governed by Swiss law. If you live in another country, you keep the protection of its mandatory consumer laws.
