1. Who we are (the data controller)
The entity legally responsible for your data is:
BuildWind srlRue Bara 173-177
1070 Brussels, Belgium
VAT number: BE0687548074
Email: [email protected]
2. What data we collect and our legal reasons
Under the general data protection regulation (GDPR), we must have a valid legal reason to process your information.
Location data: we collect your precise device location to provide real-time environmental data (wind, air quality, heat, and noise) for your exact surroundings and to help you plan safe routes.
Legal reason: your explicit consent. You can withdraw this consent at any time in your device settings.
Account information: We collect your name, surname, and email address to create and manage your user account, save your preferences, and send you relevant environmental alerts.
Legal reason: Contractual necessity. We need this information to provide the core services you requested when signing up.
3. How long we keep your data
Location data: we process your location in real-time to fetch environmental data and we store your location history only as long as necessary to provide saved route features, after which it is deleted.
Account information: we keep your profile data as long as you maintain an active account. If you choose to delete your account, your personal data will be permanently erased from our active systems.
4. Cookies and this website
Sections 1 to 3 describe the data behind our products. This section is about the website www.clara.city itself.
Cookies: the website uses one cookie, and only if you log in to a CLARA-web account. It is called clara_session and it holds nothing but a random identifier that tells our server you are logged in. It expires 30 days after you log in, or straight away when you log out. Scripts running in the page cannot read it, and it travels only over an encrypted connection.
No tracking: we use no analytics, no advertising and no tracking cookies, on any page. If you do not log in, the website stores nothing on your device. The login cookie is strictly necessary for a service you asked for, so European ePrivacy rules do not require your consent for it, and that is why you see no cookie banner. If we ever add anything beyond that, we will ask you first and update this page.
Hosting and what the pages load: the site is hosted by Cloudflare, and the icons and the styling library come from Cloudflare's public file service. The fonts are served from our own site, so no request goes to Google. Cloudflare sees the technical data any web server sees, your IP address among it, and acts as our processor.
The contact form: the name, email address and message you type are sent to us by email through Resend, our mail provider, and stay in our mailbox so we can answer you. We store them nowhere else. The form is protected by Cloudflare Turnstile, a check that tells a person apart from a script. It receives your IP address for that check and sets no cookie.
The Ask CLARA assistant: what you type is sent to Anthropic, which provides the language model that writes the answers. We keep no record of the conversation. If the assistant cannot answer, it can pass your question, along with the email address you give it, to our team by email through Resend. The same anti-spam check applies.
Legal reason: our legitimate interest in running a website that works and stays free of spam, and in replying to the people who write to us. For the login cookie, contractual necessity: your account cannot work without it.
5. Sharing your data
We do not sell your personal data. We only share your information with trusted third-party technical providers (such as secure cloud hosting servers) that are necessary to make the app work. These providers act as data processors on our behalf and are legally bound to protect your data and use it only according to our strict instructions.
6. Your rights
Under European law, you have the right to:
- Access a copy of the personal data we hold about you.
- Correct any inaccurate or incomplete information.
- Request the deletion of your data (the right to be forgotten). You can delete your account and data directly within the app settings, or by contacting us.
- Restrict or object to how we process your information.
- Download your data in a standard digital format (data portability).
- To exercise any of these rights, please email us at [email protected].
