Terms of Service

These terms apply when you use calderkit.com and the tools, plugins and services offered under the Calderkit name. In these terms, “Calderkit”, “we” and “us” mean the operator of Calderkit, and “you” means the person or organisation using our products.

1. Accepting these terms

By using a Calderkit product or buying a paid plan, you agree to these terms. If you use a product on behalf of an organisation, you confirm that you may accept these terms for it.

2. Orders and payment

Our order process is conducted by our online reseller, Dodo Payments, which is the Merchant of Record for all our orders. Dodo Payments takes the payment, issues the invoice, charges and pays any sales tax or VAT, and handles billing questions. When you buy, you also accept the terms shown at checkout.

Prices are shown on each product page before you buy. The final amount, including any tax that applies where you live, is shown at checkout.

3. Licences and plans

  • One-time purchases give you a licence to use the version you bought, plus any updates included for the period stated on the product page.
  • Subscriptions renew automatically at the end of each billing period until you cancel. You can cancel at any time from the link in your receipt email. After you cancel, you keep access until the end of the period you have paid for.
  • Usage packs (for example, a number of pages or conversions) are used up as you process files and expire after the period stated on the product page.

Licences are for you or your organisation. You may not resell, rent or share licence keys or account access outside your organisation.

4. Free tools and free plans

Some tools and plans are free. We may change their limits or stop offering them. Free plugins published in the WordPress.org directory are licensed under the GPL, and that licence applies to their code.

5. Your files and content

You keep all rights to the files and content you process with our tools. Tools that run in your browser process your files on your own device and do not send them to us. Tools that process files on our servers use them only to produce the result you asked for and delete them afterwards, as described on each product page and in our privacy policy.

You are responsible for having the right to process the files you use with our tools.

6. Acceptable use

Do not use our products to break the law, to infringe anyone's rights, to interfere with our systems or other users, or to get around usage limits or licence checks. We may suspend access that breaks these rules.

7. Results and professional advice

Our tools automate technical work. They do not give legal, accessibility-compliance, educational or other professional advice. Automated checks and fixes can miss problems or make mistakes, so review the results before you rely on them. Where a tool lists items that need human review, those items are your responsibility.

8. Availability and changes

We work to keep our products available and working, but we do not promise that they will be uninterrupted or error-free. We may improve, change or retire features. If we retire a paid product, we will tell active subscribers in advance and refund any prepaid period we can no longer provide.

9. Warranty

Apart from the promises in these terms and the rights you have under consumer law, our products are provided “as is”, without warranties of any kind.

10. Liability

To the extent the law allows, we are not liable for indirect or consequential losses, such as lost profits, lost data or business interruption. Our total liability for any claim is limited to the amount you paid us for the product concerned in the 12 months before the claim. Nothing in these terms limits liability that cannot be limited by law, or takes away rights you have as a consumer.

11. Ending your use

You can stop using our products at any time. We may end or suspend your access if you seriously or repeatedly break these terms. Sections 5, 7, 9 and 10 continue to apply after your use ends.

12. Changes to these terms

We may update these terms. The date at the top shows the latest version. If a change materially affects paid subscribers, we will tell them by email before it takes effect.
