2. Data we collect and why

Contact enquiries

When you submit the contact form or send us an email, we process your name, email address, company name (if provided) and the content of your message. We use this data solely to respond to your enquiry and, where relevant, to establish a client relationship. Legal basis: Art. 31(1) nFADP — processing is necessary to take steps at your request prior to entering into a contract, or for our legitimate interest in handling business enquiries.

Server logs

Our web infrastructure automatically records standard access logs: IP address, browser type and version, pages visited, date and time of access, and HTTP status codes. Logs are retained for a maximum of 30 days for security and troubleshooting purposes, then deleted. We do not use this data to identify individuals. Legal basis: legitimate interest in operating a secure website.

No analytics, no cookies

We do not use Google Analytics, Meta Pixel, or any third-party tracking tools. We do not set non-essential cookies. No consent banner is required.

3. Sharing of data

We do not sell, rent or trade personal data. We share data only where necessary:

  • Cloudflare (infrastructure / CDN) — processes request metadata to deliver the website. Cloudflare is EU/US Privacy Framework certified.
  • Professional advisors — lawyers, auditors and insurers where required for compliance purposes, under confidentiality obligations.
  • Regulatory authorities — where we are legally obliged to disclose information (e.g. FINMA, SFTA, anti-money-laundering supervisory bodies).

4. International transfers

The website is hosted on Cloudflare's global network. Data may be processed in the EU/EEA or US. Cloudflare operates under standard contractual clauses and the EU/US Data Privacy Framework, providing adequate safeguards under Art. 16 nFADP.

5. Retention

Client and contractual data is retained for 10 years following the end of a mandate, as required by Swiss commercial law (Art. 958f OR). Enquiry data from non-clients is deleted after 12 months if no mandate is established. Server logs: 30 days.

6. Your rights

Under the nFADP you have the right to:

  • Access — obtain a copy of the personal data we hold about you.
  • Rectification — correct inaccurate data.
  • Erasure — request deletion, subject to statutory retention obligations.
  • Restriction — limit processing in certain circumstances.
  • Portability — receive data in a machine-readable format where processing is automated.
  • Objection — object to processing based on legitimate interest.

To exercise any right, contact us at info@accounting-zug.com. We respond within 30 days. If you believe we have processed your data unlawfully, you may lodge a complaint with the Swiss Federal Data Protection and Information Commissioner (FDPIC): edoeb.admin.ch.

7. Security

The website is served exclusively over HTTPS with HSTS enforced. We apply industry-standard technical and organisational security measures to protect data against unauthorised access, loss or destruction.

8. Changes to this policy

We may update this policy from time to time. The date at the top of this page reflects the last revision. Continued use of this website after an update constitutes acceptance of the revised policy.
