What we collect

When you send a project enquiry, we collect the details you enter: your first and last name, work email address, company and the type of enquiry. Depending on what you choose to share, we may also collect your job title, phone number, country, preferred contact method, how you heard about us, the services you are interested in, your project stage, a description of the work, budget range, target timing, a link to supporting documents and whether you would like a non-disclosure agreement. We record your consent to be contacted, the page the enquiry was sent from, and the date and time.

To prevent spam, the server keeps a one-way hash of your network address and browser for up to ten minutes. It is not linked to your enquiry and cannot be used to identify you.

If you email us directly, we receive your email address and whatever you include in your message.

Why we use it

We use enquiry information only to review and reply to your enquiry and to discuss a possible engagement. We do not use it for marketing unless you separately agree, and we never sell it.

Where it is stored and who processes it

Enquiries are stored in the website’s administration system, which only authorized staff can access. A notification with the enquiry reference, the selected service and your message is sent by email to the team that replies. The website is hosted by GoDaddy, which processes the data on our behalf as our hosting provider.

How long we keep it

We keep enquiries for as long as we need them to reply and to manage any resulting discussion or engagement. Enquiries that do not lead to further contact are deleted within 24 months.

Your rights

You can ask us to show, correct or delete the information we hold about you, or object to how we use it. Email david@hanoitechnology.com and we will reply within 30 days.
