What we collect, why we collect it, and the choices you have.
Last updated: 6 October 2025
This website is operated by Deepstack Technologies Ltd, a company registered in England and Wales under company number 16765109, with its registered office at 128 City Road, London, United Kingdom, EC1V 2NX. In this policy, "we", "us" and "our" refer to that company. We are the data controller for personal information collected through this website.
You can reach us about anything in this policy at hello@deepstacktechnologies.com.
We collect only what you choose to send us. We do not run advertising or analytics on this site, and we do not build visitor profiles.
Information you give us. When you submit the contact form, we collect:
If you email us directly instead, we receive whatever your message contains.
Information collected automatically. Our hosting provider keeps standard server logs, which typically record IP addresses, browser type, pages requested and timestamps. The third-party services described in section 4 also receive your IP address when their content loads.
Cookies. This website sets no cookies of its own. One third-party service does set cookies on our contact page. See our Cookie Policy for the detail.
Our lawful basis. Under the UK GDPR we rely on our legitimate interests (Article 6(1)(f)) for each of the above: responding to a business enquiry you chose to send us, keeping accurate records of our business correspondence, and protecting our website and our inbox from automated abuse. We consider these interests are not overridden by your rights and freedoms, because you choose what to send us and you can ask us to erase it at any time.
If we ever send you marketing, we will rely on your consent, and every message will include a way to unsubscribe.
We do not sell your personal information, and we do not share it for advertising.
Running this site involves a small number of outside services. Each receives only what is described below.
We are based in the United Kingdom. Some of the providers listed above process personal data outside the UK, including in the United States.
Where that happens, we rely on the transfer mechanisms recognised under UK law: the UK's adequacy regulations where they apply, including the UK Extension to the EU–US Data Privacy Framework for recipients certified under it, or the UK International Data Transfer Agreement or the UK Addendum to the EU Standard Contractual Clauses. You can ask us which mechanism applies to a particular provider.
We keep enquiry correspondence for one month after our last contact with you, unless we go on to work together. Where we do work together, your information is retained for the life of that relationship and for five years afterwards, so that we can meet our legal, tax and accounting obligations and deal with any claim arising from the work.
Server logs are retained for one year.
Under the UK GDPR you have the right to ask us for a copy of the information we hold about you, to correct it if it is wrong, to have it erased, to restrict how we use it, or to receive it in a portable format. Because we rely on legitimate interests, you also have the right to object to our use of your information at any time. Where we rely on your consent, you may withdraw it at any time.
To exercise any of these, email hello@deepstacktechnologies.com. We will respond within 30 days, and exercising these rights is free.
If you are unhappy with how we have handled your information, you can complain to the Information Commissioner's Office, the UK supervisory authority, at ico.org.uk. We would appreciate the chance to address your concern first.
This site is served over HTTPS, and form submissions are transmitted over an encrypted connection. No method of transmission or storage is completely secure, so we cannot guarantee absolute security, but we take reasonable steps to protect the information you send us.
This site is intended for business users. We do not knowingly collect personal information from children under 16. If you believe a child has sent us personal information, contact us and we will delete it.
If we change this policy we will update the date at the top of this page. Significant changes will be made clear on this page.
Questions about this policy can be sent to hello@deepstacktechnologies.com or through our contact page.
