Enquiries and contact
We use the information you send to handle your enquiry, reply and, when requested, prepare a service proposal. Contacting us does not subscribe you to a newsletter or authorise advertising.
The form prepares a draft in your email application. The name, company, email and message you enter stay in your browser until you choose to send them from that application. They are not sent through FormSubmit or stored in a form database. If you have no email application configured, write directly to info@threesefficiency.com. Avoid including sensitive information or unnecessary information about other people.
Legal basis and retention
Requests for information or quotations about our services are processed to take steps at the request of the individual before entering a contract. Other enquiries are handled on the basis of our legitimate interest in responding to communications, taking the sender's rights into account. You may object to processing based on that interest.
We retain correspondence while needed to handle the enquiry and follow-up. Afterwards, only information needed to meet legal obligations or address potential liabilities is retained for the applicable periods. If a contractual relationship is established, its specific retention obligations apply.
Service providers and browsing
Email is received through IONOS. The website is hosted using OpenAI Sites and Cloudflare infrastructure. Hosting, security and email services may process technical data such as IP address, date, browser and information needed to deliver pages or messages. The website application does not incorporate Google Analytics or advertising pixels.
These providers may use international infrastructure. Their policies describe their processing and transfer mechanisms; you may ask Threes for information about safeguards applicable to your data. See OpenAI, Cloudflare and IONOS. We do not sell enquiry data.
Your rights
You may request access, rectification, erasure, restriction, objection and, where applicable, portability by emailing info@threesefficiency.com. Where consent is the basis for processing, you may withdraw it without affecting the lawfulness of earlier processing. You may lodge a complaint with the Spanish Data Protection Agency.
We do not use enquiries for automated decisions with legal effects or automated commercial profiling.
