Terms of use

Last updated 10 November 2026

The short version: use zhttp on traffic you're allowed to inspect. It comes as it is, and you're responsible for how you use it.

Who we are

These terms are between you and Yoghurt Digital Ltd ("we", "us"), registered in England and Wales, company number 13295779, with its registered office at 86–90 Paul Street, London EC2A 4NE. They cover this website and the zhttp desktop app and command-line engine ("zhttp"). By downloading or using zhttp, you agree to them.

Using zhttp

You may use zhttp to inspect, debug and test the traffic of apps, devices and accounts that you own, or that you have permission to test. You must not use it to:

• intercept or change anyone else's traffic without their permission;
• get into systems, accounts or data you aren't authorised to access;
• break the law, or harm other people or the services you connect to;
• collect other people's personal information without a lawful basis.

You're responsible for how you use zhttp and for the data you capture with it.

Your licence

zhttp belongs to Yoghurt Digital Ltd. We give you a personal, non-exclusive licence to install and use it under these terms. You may not sell, rent, sublicense or redistribute zhttp, or remove its copyright notices.

Certificates and security

zhttp creates a certificate authority on your computer. Installing it on a device lets zhttp decrypt that device's traffic. Keep its private key private, and remove the certificate from a device when you've finished with it.

No warranty

zhttp is provided "as is". We work to keep it reliable, but we don't promise that it will be free of faults, suit every purpose or work with every app and server.

Our liability

As far as the law allows, we aren't liable for any loss of data, profit or business, or for any indirect or consequential loss, that comes from using zhttp or this website. Nothing in these terms limits liability that can't be limited by law, such as for death or personal injury caused by negligence, or for fraud. If you're a consumer, you also have legal rights that these terms don't affect.

This website

The content of this website belongs to Yoghurt Digital Ltd. You may link to it and share it, but not copy it to pass it off as your own.

Changes to these terms

We may update these terms. When we do, we'll change the date at the top. If you keep using zhttp after an update, the new terms apply.

Law

These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction.
