Terms of use

About these terms

These terms apply when you use iframecheck.com ("iframecheck"). When you use the site, you accept these terms. If you do not accept them, do not use the site.

Dobroslav Radosavljevič, a private person in the Czech Republic, runs iframecheck. In these terms, "we" and "us" mean Dobroslav Radosavljevič. Email: business@dobroslavlabs.com

The privacy policy tells you what happens to your personal data.

What iframecheck is

iframecheck is a free tool that tells you if a page can be shown in an iframe on another site.

You enter a URL. Our server requests that URL once and reads the response headers. It stops before it reads the page body, and it follows up to 5 redirects. Then iframecheck shows a verdict (embeddable, partial, blocked or unreachable), the headers and the fixes. Your browser also loads the page in a preview.

The site also has a responsive preview, a sandbox playground, an embed code tool, a bulk check for up to 100 URLs in one run, and guides. There is no public API.

We can add, change or remove any tool, page or feature, and we can stop the site.

Results can be wrong

A result is our best effort. It shows what our server got from the page at the time of the check. Your visitors can get a different answer, for example because:

• the site sends different headers to different regions
• the site sends different headers when you are logged in, or when you have its cookies
• a firewall or bot protection, such as Cloudflare, answers our server in a different way than a real browser
• the site changed its headers after the check

Our server cannot reach private networks or pages that need a login. For those pages, the result can be "unreachable" or wrong.

Test the page in a real browser on your own site before you depend on the result.

iframecheck is not security advice. A page that can be embedded is not always safe to embed, and a header that allows embedding can open your site to clickjacking. Clickjacking is an attack where a site shows your page in a hidden frame and tricks people into clicking on it. Decide for yourself which headers are right for your site.

If you find an error, please tell us. We fix errors when we find them.

Guides and code snippets

The guides, the fixes and the code snippets on iframecheck are provided as they are. Server software, hosts and frameworks change, and a snippet can be out of date.

Test each change on a test site before you put it in production. You are responsible for the changes that you make to your own site.

You may copy the code snippets into your own projects, free of charge.

Pages that you test

The preview, the responsive preview and the sandbox playground load the page that you test directly in your browser. That page is not part of iframecheck. We do not control it and are not responsible for it. It can run its own scripts inside the frame, and its own terms and privacy policy apply.

Only test URLs that you trust.

How you may use iframecheck

You may:

• use the tools to check pages, including pages of other sites, in normal use
• share links to iframecheck pages
• quote short parts of the guides, with a link to the page
• use iframecheck with search engines, AI assistants and other crawlers that follow our robots.txt

You may not, without our written permission:

• use iframecheck to probe systems that you are not allowed to test
• use iframecheck to attack a site, or to send a lot of traffic to it
• send automated or bulk checks with scripts or bots. Use the bulk check, which allows 100 URLs in one run.
• copy all or a large part of the site, or copy small parts again and again, to republish it or to build a service that competes with iframecheck
• study or reverse-engineer the check service to use it against other sites
• try to go around the limits of the check service, for example the block on private networks or the rate limit
• send so many requests that the site gets slow or stops
• go around our robots.txt or our security measures
• show iframecheck as your own work
• use iframecheck for anything that breaks the law

If you break these terms, we can block your access.

The text, the design and the code of iframecheck belong to us. These terms do not take away a right that the law gives you, for example the right to quote.

To ask for permission, write to us.

Names and other sites

Names and trademarks

Names and trademarks of other companies and products, for example of hosts and frameworks in the guides, belong to their owners. We use them only to name those products. Their use does not mean that the owner supports or works with iframecheck.

Links to other sites

iframecheck links to other sites, for example to documentation. We do not control them and are not responsible for them. Their own terms and privacy policies apply.

Suggestions and reports

When you send us a suggestion, a correction or other text, you let us use it free of charge to fix and improve iframecheck. We decide what we publish.

Do not send secrets or personal data of other people.

Warranty and liability

No warranty

We try to give correct results and to keep the site available. We do not promise that a result, a guide or a code snippet is complete, correct or current, or that the site always works.

Liability

iframecheck is free. We are not liable for a loss that comes from your use of iframecheck, its results, its guides or its code snippets. For example, we are not liable for a decision that you make from a result, for a change that you make to your site, for what a page does in the preview, or for a time when the site does not work.

This section does not limit liability that Czech law does not let us limit. This includes harm to life or health, and harm that we cause on purpose or by gross negligence (Section 2898 of the Czech Civil Code). It also does not limit your rights as a consumer.

Law and courts

Czech law applies to these terms. If you are a consumer, you also keep the protection of the mandatory rules of the law of the country where you live.

The Czech courts decide disputes. If you are a consumer, you can also go to the courts of the country where you live.

Changes and other points

We can change these terms. When they change, the "Last updated" date at the top changes too. The new terms apply from that date, and only to use of the site after that date.

If a court finds that a part of these terms is not valid, the other parts stay valid. If we do not act on a breach, we can still act on it later. These terms and the privacy policy are the full agreement about your use of iframecheck.
