Data Processing Terms

Version 1, effective 19 October 2026

These terms form part of our AI Assistant Terms. They cover the personal data in the chats and calls your AI assistant handles. For that data you are the controller and Altrensa Limited (company number 17512604) is your processor, as described in Article 28 of the UK GDPR.

2. What we do

We will:

  • process your personal data only on your documented instructions, which are the AI Assistant Terms, your plan and the set-up we agree with you, unless the law requires otherwise, in which case we tell you first where we can;
  • make sure anyone who can access the data is bound by confidentiality;
  • keep the data secure, including encryption in transit, access limited to the people who run your assistant, and two-factor sign-in on our supplier accounts;
  • tell you without undue delay, and in any event within 48 hours, after becoming aware of a personal data breach affecting your data;
  • help you respond to requests from people exercising their data rights, and with your security, breach and impact assessment duties;
  • delete or return your data when the service ends, as set out in clause 7.4 of the AI Assistant Terms;
  • give you the information you need to show these terms are being met, and allow a reasonable audit on 30 days' notice, no more than once a year unless there has been a breach.

3. Sub-processors

You give us general permission to use the sub-processors below. Each one is bound by data protection terms that protect your data at least as well as these.

We will tell you by email at least 30 days before we add or replace a sub-processor. If you object on reasonable data protection grounds, you can end your service before the change applies, without a notice period.

4. Transfers outside the UK

Where a sub-processor processes personal data outside the UK, the transfer is covered by UK adequacy regulations, including the UK Extension to the EU-US Data Privacy Framework where the supplier is certified, or by the ICO's International Data Transfer Agreement or UK Addendum in that supplier's data processing terms.

5. Your part

You make sure you have a lawful basis for the data your assistant handles, and a special category condition where callers share health details. You tell callers and visitors about the assistant in your own privacy notice. Your instructions to us must be lawful.
