Privacy Policy
MultiWindows' privacy and personal data protection policy.
Privacy Policy
Your privacy matters to us. This policy explains how MultiWindows collects, uses and protects your personal data.
1. Data controller
MultiWindows is the entity responsible for processing the personal data collected through this website and its contact and quote forms.
2. Data we collect
We collect the data you provide voluntarily — such as name, email, phone, location and your project details — when you request a quote, contact us or use the support assistant. The website also stores functional preferences in your browser (such as your chosen language), which do not identify you.
3. Purpose of processing
We use your data to respond to quote and contact requests, provide technical support, manage the commercial relationship and improve our services and website. We do not use your data for purposes incompatible with these.
The legal basis for processing is your consent (given when you submit the forms) and the performance of pre-contractual steps taken at your request, under Article 6 of the GDPR.
4. Data sharing
We do not sell your personal data. Data may only be shared with service providers necessary to run the business (for example, installation and after-sales support) and where required by law.
5. Data retention
We retain your data only for as long as necessary for the purposes described and to comply with applicable legal obligations.
6. Your rights
Under the GDPR, you have the right to access, rectify, erase, restrict or object to the processing of your data, as well as the right to data portability. To exercise these rights, contact us using the details below.
7. Cookies
This website only uses strictly functional cookies and local storage — for example, to remember your language preference. We do not use advertising or traffic-analysis cookies. You can manage or clear this data in your browser settings. If the quote form is provided through an external service (HubSpot), that service is only loaded if you accepted cookies in the notice shown on your first visit.
