Who we are
This website is run by Advertain Ltd, a company registered in England and Wales (company number 17477004), whose registered office is at 12 Old Bond Street, Mayfair, London W1S 4PW ("Advertain", "we", "us").
We are the controller of the personal information described in this policy. If you have any questions about it, or want to use any of your rights, email us at hello@advertain.com or write to us at our registered office.
Information we collect
We collect the following kinds of personal information:
- Enquiries. When you use a contact form on our website, we collect your name, company, email address and whatever you tell us about your project.
- Correspondence. When you email, call or message us, we keep a record of those conversations and the contact details you share.
- Business contacts. We keep work contact details (such as name, job title, company and work email) for people at brands and agencies we work with, are speaking to, or think may be interested in our services. We get these from you, from introductions, or from public business sources such as company websites and LinkedIn.
- Clients and suppliers. When we work with you, we hold the contact, billing and project information needed to deliver and get paid for the work.
- Client portals. If we share a private proposal page with you, we collect the name, choices and notes you submit on it.
- Technical information. When you visit the site, your IP address, browser and device information are processed by our hosting and security providers so the site can load and stay protected from spam and abuse.
We do not use analytics or advertising tracking on this website, and we do not knowingly collect information from children.
How we use your information and our legal basis
Under UK data protection law we must have a lawful basis for each use of your information. We rely on:
| What we do | Lawful basis |
|---|---|
| Reply to enquiries and arrange calls | Legitimate interests in responding to people who contact us, and taking steps at your request before entering into a contract |
| Deliver services to clients and manage the relationship | Performance of a contract |
| Send invoices, keep accounts and meet tax and company law duties | Legal obligation |
| Contact people at businesses about our services (business to business) | Legitimate interests in growing our business. You can opt out at any time |
| Keep the website secure and working | Legitimate interests in protecting our site and visitors |
| Send you a newsletter or marketing to a personal email address | Consent, which you can withdraw at any time |
Who we share it with
We do not sell your personal information. We share it only with service providers who help us run the business, under contracts that require them to protect it:
- Webflow, which hosts this website and stores form submissions
- Cloudflare, which provides security, spam protection and file delivery for the site
- Google, which provides our email, documents and calendars (Google Workspace), and the fonts and map shown on the site
- Our accountants, bank, lawyers and other professional advisers
- Trusted production and community management partners, only where needed to deliver work you have asked us for
We may also share information where the law requires it, or with a buyer if our business is ever sold.
International transfers
Some of our providers, including Webflow, Cloudflare and Google, process information in the United States and other countries outside the UK. Where they do, we rely on protections recognised under UK law, such as the UK Extension to the EU US Data Privacy Framework or the UK International Data Transfer Addendum to standard contractual clauses.
How long we keep it
- Enquiries that do not lead to work: up to 2 years after our last contact
- Business contacts: for as long as there is a reasonable business reason to stay in touch, and removed promptly if you ask us to stop contacting you
- Client, contract and financial records: 6 years after the end of the financial year they relate to, to meet UK tax and company law requirements

Security
We use reputable providers, secure connections, access controls and two step verification on our business accounts to protect your information. No system is completely secure, but we work to keep the risk as low as possible.
