TILED ROOF SPECIALISTS
Your data and photos
How the roof designer, roof plan and email quote request handle the information you enter.
Opening and editing your roof photo
Your chosen photo is opened in your browser. Converting a HEIC or HEIF photo to JPG also happens on your device. In the manual roof designer, the photo, roof selection and colour choices stay in the page’s memory. They are not sent to an AI service.
Before adding a photo to a quote request, the browser creates a smaller JPG copy without the original EXIF metadata, such as location data. Details visible in the photo remain visible. Choose only photos needed for your roofing enquiry that you are entitled to use. Downloading a roof impression saves a labelled image on your device; you decide whether to share it.
Taking a photo to your quote request
Only when you choose the designer’s action to request a quote with this photo do we temporarily place a reduced copy of your original photo and, if you created one, your labelled roof impression in your browser’s tab storage. This lets the quote form display them. This step does not send anything to us.
The transfer is available for up to 30 minutes and is removed from temporary storage after the quote form loads it. Closing the browser tab also clears this tab storage. You can review and remove transferred photos before sending. Without this transfer, refreshing or leaving the designer clears the photo and markings. Refreshing or leaving the quote form clears your entries and selected photos.
Automatic roof recognition
The upload area shows whether automatic recognition is available. The automatic-recognition checkbox and the explanation about OpenAI appear before you choose a photo. If the option is checked and you then choose a photo, your browser sends a reduced JPG copy through our server to OpenAI to identify roof areas and exclusions. The longest side is at most 1280 pixels. The original filename and EXIF metadata, such as location data, are not sent. Details visible in the photo remain visible.
Uncheck the option before choosing your photo to select the roof manually; that upload does not send a photo to the AI service. Manual adjustment remains available if recognition is unavailable or unsuccessful. Choosing to run automatic recognition again sends another reduced copy. Trying colours, adjusting the selection and downloading happen in your browser.
For recognition, we do not persist the photo or recognition response on our server, in our own database or in a photo folder. We request that OpenAI not store the response for later retrieval (store: false). This does not exclude processing in OpenAI’s security and abuse-monitoring logs. See the OpenAI API data controls.
Quote request and roof plan
Your name, email address, town, optional phone number, roof wishes and selected photos stay on this page while you complete the form. Photos are optional. You can add up to five photos, each original no larger than 15 MB, and see them again when reviewing your request.
Only after you select the final send action are your details and attached JPG copies sent over the secure website connection and emailed to info@dakdekkers247.nl. The email also identifies this website, the page where your request started and the form page, so we can identify the relevant product or topic. Search terms, browsing history and advertising data are not included.
Sending uses a necessary session cookie and temporary security counters to limit misuse and duplicate submissions. These counters contain no form content or photos and expire within 24 hours. Requests and photos are not stored in a website database or a public photo folder. The email and attachments are processed by the mail provider and kept in the receiving mailbox.
Downloading your roof plan creates a local text file with your entries, wishes and checklist, but no photos. Downloading alone does not send a request and does not require contact details. Save any download you want to keep before leaving the page. If you choose a WhatsApp link, that service’s privacy terms apply.
Hosting and external links
The hosting provider delivers the website, example images and photo software and may process technical connection and security data. No advertising or analytics trackers have been added to this site’s code. Temporary tab storage for your chosen photo transfer is described above. External manufacturer and information websites have their own privacy policies.
