This site collects nothing.
Not a qualified nothing. There are no cookies, no analytics, no tag managers, no advertising pixels, no embedded fonts from anyone else's server, and no form on this site that posts data anywhere.
The website
- No cookies. The site sets none, so there is no cookie banner to dismiss.
- No analytics. We do not run a visitor analytics product and we do not know who reads this.
- No third-party resources. Typefaces, stylesheets, scripts and images are all served from this domain. Nothing calls out to another company as you read.
- The enquiry form does not submit. It assembles what you typed into a message and hands it to your own email program. If you close that message, nothing has left your computer.
- Server logs. Our hosting provider keeps ordinary request logs, including IP addresses, for operational and security purposes. We do not analyse them and do not combine them with anything else.
If you write to us
Email you send reaches an ordinary business mailbox. We keep correspondence for as long as it is commercially and legally necessary — typically the life of the engagement plus the limitation period that applies to the work — and then we delete it. We do not add you to a mailing list, because we do not have one.
Client information
Material you give us under an engagement — alignments, geotechnical reports, drill records, tender documents, incident files — is treated as confidential, is not used for any other client, and is not used in our own marketing. That is why the project descriptions on this site name the ground and the method but never the operator. Where you have your own non-disclosure agreement, we sign yours.
Your rights
Canadian privacy law gives you the right to ask what personal information we hold about you, to have it corrected, and to ask us to delete it. Write to enquiries@techhdd.com and we will deal with it.
