Terms of Use
Last updated 1 November 2026
These terms apply when you use Casla Tools at tools.casla.app (the "service"). The service is provided by Casla Agency Limited ("Casla", "we", "us"). By using the service you agree to these terms. If you don't agree, please don't use it.
Using the service
Casla Tools is a set of browser-based utilities for previewing, converting and tidying content. Some tools are open to everyone; others (marked with a padlock) need a free account. You must provide accurate sign-in details and keep your password safe. You must be at least 18 years old to use the service, and by using it you confirm that you are. If you are under 18, you may not create an account or use the service.
Your content
Anything you paste, upload or generate with the service ("your content") stays yours. We don't claim any ownership of it. You are responsible for making sure you have the right to process any content you put into the service, including personal data about other people.
Most tools run entirely in your browser and your content never reaches our servers. For the AI-powered tools (such as Tidying up names, Structuring locations, Does this email match? and Transcribe audio), the content you submit is sent to third-party AI providers in order to produce the result. See our Privacy Policy for details.
Acceptable use
- Don't use the service for anything unlawful, harmful or fraudulent.
- Don't upload malware or try to break into, overload or disrupt the service.
- Don't resell or repackage the service without our written permission.
- Don't use the service in a way that infringes anyone else's rights.
We may suspend or remove accounts that breach these rules.
Availability and changes
The service is provided "as is" and "as available". We aim to keep it running well, but we don't promise it will be uninterrupted or error-free, and we may add, change, suspend or remove tools at any time. We may update these terms from time to time; continued use of the service after a change means you accept the updated terms.
Guidance and reference information
Some tools give general guidance, such as the B2B email rules by country (last updated November 2026). This reflects Casla's understanding at the time and is a guide only. It is not legal advice and may be incomplete, out of date or wrong. You use it at your own discretion and remain responsible for making sure your email outreach and other activity comply with the law. Casla accepts no responsibility for any breach of the rules or any decision you make based on this information.
Liability
The service is free and provided without warranties of any kind. To the fullest extent permitted by law, Casla accepts no liability for any loss or damage arising from your use of the service or your content, including lost data, lost profits or business interruption. Nothing in these terms excludes liability that cannot be excluded under English law.
Governing law
These terms are governed by the laws of England and Wales, and the courts of England and Wales have exclusive jurisdiction over any dispute arising from them.
