C the Signs is registered as a Class 1 device with the Medicines & Healthcare products Regulatory Agency (MHRA). Therefore, we operate under the Medical Devices Directive and report any patient safety concerns directly to the MHRA. You may report any incident to us or directly to the MHRA through the Yellow Card Scheme.

The tool uses the National Institute for Health and Care Excellence (NICE) Cancer: recognition and referral (NG12) guideline. We are also currently part of the NICE endorsement programme. We have registered with NICE for updates to the guideline and will make any necessary changes to the tool.

The tool is updated with each guideline update. We aim to do this within 2 business days (but this is limited by the publishing protocol of the AppStore). We will aim to receive an advanced copy of any guideline changes so we can make sure these updates coincide with the release. However, if there are urgent and unforeseen changes required, we can give immediate messages via push notifications as well as through direct email.
