What we collect, and why

This website does not use cookies, analytics or tracking tools, and does not load content from other websites. Our fonts are stored on this website.

When you email us or use the contact form, we process your name, email address, organisation (if given) and anything you choose to tell us, in order to reply to you and, if we work together, to prepare and carry out the engagement.

Our hosting provider automatically records technical data when you visit the website (such as IP address, browser type, date and time of access) in order to deliver it securely. We do not use this data to identify you.

Who we share it with

We use Netlify, Inc. to host this website and to receive contact form messages, and Google Workspace (Google) for email and documents. These providers may process data in the United States. Both are certified under the Swiss-U.S. Data Privacy Framework, which the Swiss Federal Council recognises as providing an adequate level of data protection. We do not sell personal data or share it for marketing.

How long we keep it

We keep correspondence only as long as needed for the purpose for which it was sent. Engagement and accounting records are kept for as long as Swiss law requires, generally ten years. Our hosting provider keeps technical logs for a limited period only.

Your rights

Under the Swiss Federal Act on Data Protection, and where it applies the EU General Data Protection Regulation, you may ask to access, correct or delete your personal data, or object to its processing. Write to hello@tsela-advisory.com. You may also contact the Swiss Federal Data Protection and Information Commissioner (FDPIC).
