Website content is prepared carefully, but technical, factual or typographical errors cannot be excluded completely. Information on yield, savings, incentives, tariffs, payback and mining is indicative unless expressly guaranteed in writing.

Text, images, graphics, calculation logic and design are protected by copyright unless stated otherwise. Prior permission is required for reuse.

1. Controller and scope

PHT Energietechnik GmbH, Churerstrasse 158, 8808 Pfäffikon SZ, Switzerland, is responsible for processing personal data on this website. Privacy contact: info@pht-energie.ch. This notice applies to pht-energie.ch and contacts initiated through it.

2. Data processed and purposes

We process the identity, contact, building, energy, project and communication data you provide, including photographs sent voluntarily. Purposes include responding, assessing projects, advising, quoting, designing, performing contracts, installing, maintaining, invoicing, supporting customers, security and legal compliance. Processing is based on pre-contractual or contractual necessity, overriding private interests, legal obligations or - where expressly requested - consent.

3. Contact form, email and telephone

The contact form sends your details to PHT by email; the message is not additionally stored in a website database. Required fields are marked with * in the form; usually these are name, telephone number, details of your project and confirmation that you have acknowledged this notice. Optional details such as email address or town can be left out. Without the required details we cannot process the enquiry reliably.

4. Hosting, log data and abuse prevention

The website and email service are provided through Hostinger International Limited, 61 Lordou Vironos Street, 6023 Larnaca, Cyprus. A visit processes technical data needed to deliver and protect the site, including IP address, date and time, requested URL, referrer, browser, operating system and status code. PHT provides for deletion or anonymisation of server logs within 30 days unless a security incident or legal duty requires longer retention. To limit abusive form submissions, the IP address is hashed and used for a 15-minute review window; expired entries are removed on the next form request.

5. Google Analytics, Google Ads and consent

Google Analytics 4 and Google Ads are loaded only after you consent in the privacy banner. They measure website use and advertising effectiveness, including page views, confirmed form enquiries, and phone or WhatsApp clicks. A click is not a confirmed enquiry. IP address, device and browser information, referrer and visited pages may be transmitted to Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland, and affiliates including Google LLC in the USA. Google may use cookies or similar storage. Our tracking implementation does not send form contents, names, email addresses or phone numbers to Google. Google Ads receives a random enquiry ID to prevent duplicate conversions. Google Signals and personalised advertising signals are disabled in our implementation. Without consent, the Google tag is not loaded and no conversion is sent.

6. Local storage and changing your choice

Your Analytics and Ads choice is stored locally as pht_measurement_consent_v2 for up to 180 days. You can change it at any time using Privacy settings in the footer. After withdrawal and reload, the services are no longer loaded; earlier processing is unaffected. Anonymous enquiry IDs are stored for the browser session to prevent duplicate measurements. The server temporarily retains anonymous sending receipts without contact details so retries do not send the same enquiry repeatedly. Receipts are valid for 24 hours; expired files are cleaned up during later requests.

7. WhatsApp

WhatsApp is included only as an external link. You leave our website only when you click it. WhatsApp Ireland Limited and Meta group companies then process information such as your telephone number, communications, device data and message content; processing may occur outside Switzerland. Email and telephone are equivalent contact alternatives without WhatsApp.

8. Recipients, processors and international transfers

Access is limited to staff and service providers who need it for the stated purpose. For quotations and projects, data may be disclosed to manufacturers, suppliers, subcontractors, grid operators, authorities, financing or leasing partners and IT, hosting and email providers. Processing takes place mainly in Switzerland and the European Economic Area. Where data is transferred to a country without a recognised adequate level of protection, we use recognised safeguards such as standard contractual clauses where required or rely on a statutory exception.

9. Retention

Non-binding enquiries are generally retained for up to 24 months after contact ends. Contract, project, warranty, accounting and tax records are normally retained for 10 years in line with legal duties. Project photographs are used only for documentation and agreed purposes; publication for advertising requires a separate release. Longer retention is possible where claims exist, proceedings are pending or a legal duty applies. Google and WhatsApp additionally determine retention in their systems under their linked policies and account settings.

10. Your rights and security

Under applicable law you may request access, delivery or portability, correction and deletion, object to processing and withdraw consent by writing to info@pht-energie.ch. Proof of identity may be required. You may also contact the Swiss Federal Data Protection and Information Commissioner. We use appropriate technical and organisational safeguards but cannot guarantee absolute security for Internet transmissions. Swiss data protection law applies; additional rules may apply to targeted offerings in the EEA. Updated: 15 August 2026.

The full terms cover design, advice, supply, installation, commissioning, maintenance and optimisation. For contracts from 15 August 2026, the binding version is the German PDF dated 15 August 2026; this English summary aids understanding.
