Politique de confidentialité

This site is operated in compliance with the revised Swiss Federal Act on Data Protection (revFADP / nLPD / revDSG), in force since 1 September 2023.

Data we collect

When you request a quote we collect: first name, last name, email, phone, address, coordinates of the building, your roof's solar potential summary, bill range, project timeline and ownership status. We also store a one-way hash of your IP address and your browser's user-agent string for fraud prevention.

Purpose

Your data is used to prepare non-binding solar quotes from certified installers in your region and to contact you about them. Your contact details are forwarded only to the installers we select for your file, and only after your explicit consent.

Retention

Roof analysis cache entries are retained for up to 30 days and may be deleted at any time on request.

Your rights

Under the revFADP you have the right to access, correct or delete your personal data. Send any request to info@helvesolar.ch and we will respond within 30 days.

Third-party services

Address autocomplete and mapping are powered by swisstopo (api3.geo.admin.ch, wmts.geo.admin.ch). Solar data is provided by the Swiss Federal Office of Energy (Sonnendach). No tracking cookies, no advertising pixels.
