Privacy notice
Last updated 13 November 2026. This notice covers the Construction OS research surveys and optional pilot contact list.
Who is responsible
GDA Consulting Ltd, registered in England and Wales, company 16925441. Registered office: 71–75 Shelton Street, London WC2H 9JQ. Contact contact@gdatech.co.uk for questions or privacy requests.
What we collect and why
We collect the name, email, business profile and answers you enter, your selected offer, separate contact preferences, submission time, campaign tags in the page URL and whether you started an available demo video. We use this to evaluate demand, avoid counting the same business twice and shape the pilot. Please do not include your customers’ personal information or confidential job details.
Our basis for research and keeping the service secure is our legitimate interest in understanding business needs and preventing abuse. Pilot and product marketing emails require your optional consent. A requested workflow conversation is handled separately, to respond to your request. You can submit feedback without either contact option. We do not take payments or make automated decisions with legal or similarly significant effects.
Hosting and access
Cloudflare provides website delivery, security and D1 database storage. GDA Consulting Ltd reviews responses privately. Cloudflare processes technical request information, including IP addresses, for delivery and abuse prevention; IP addresses are not included in our survey response records. We do not sell your information or upload your survey answers to advertising platforms.
Cloudflare operates internationally; processing may occur outside the UK or Canada. Its published Data Processing Addendum describes transfer arrangements, including standard contractual clauses and the UK Addendum. Contact us for more information about the safeguards relevant to this service.
Retention
Research responses are reviewed within six months of submission and deleted or anonymised when no longer needed for the pilot evaluation. Contact details for optional updates are kept while you remain interested in the pilot, subject to a review after twelve months without engagement. If you unsubscribe, we stop marketing and retain only the minimum record needed to respect your choice. Backups may retain earlier records until their normal expiry.
Your choices and rights
Email contact@gdatech.co.uk to request access, correction or deletion; object to research processing; request restriction or portability where applicable; or withdraw marketing consent. Withdrawal does not affect processing already carried out. You can unsubscribe using the same address, whether or not an email has yet been sent.
You may raise a concern with us or complain to the UK Information Commissioner’s Office. Canadian respondents may also contact the Office of the Privacy Commissioner of Canada or their applicable provincial privacy regulator.
Cookies and advertising
This survey does not install advertising pixels or analytics cookies. Responses are kept in memory while you fill the form and are sent only when you submit. Technical security measures may be used by the hosting provider. Campaign tags allow us to associate a submitted response with an ad or link; we do not send your free-text answers or email to an advertising platform. Any future advertising tracking will be described here before it is enabled.
