Privacy Policy

Last updated: 8 November 2026

Who is responsible

This website is run by Rhyline, Sebastián Ahumada Álvarez, Basel, Switzerland.

This policy explains which personal data we collect through this website, why we collect it and what rights you have. It follows the Swiss Federal Act on Data Protection (FADP). Where the EU General Data Protection Regulation (GDPR) applies to you, you also have the rights it gives you.

When you visit the website

Our hosting provider, Hostinger, automatically records technical information when you visit, such as your IP address, the date and time, the pages you open and your browser type. This is needed to deliver the website and keep it secure. We do not use these records to identify you.

We do not use analytics, advertising or social media tracking tools on this website.

Cookies

The website does not use cookies to track visitors. Technical cookies may be set if you log in to the website administration.

When you contact us

If you use the contact form or write to us, we process the details you send: your name, company, email address, phone number, the topic you choose and your message. We use them only to reply to your enquiry and, if you ask for one, to prepare a proposal. The form sends your message to us by email.

We keep enquiries for as long as we need them to deal with your request and any follow-up, and then delete them, unless the law requires us to keep them longer.

When you book a meeting

You can book a meeting with us through Cal.com, a scheduling service run by Cal.com, Inc. in the USA. The booking window loads from Cal.com only when you click a “Book a meeting” link. Until then, your browser does not contact Cal.com. When you book, Cal.com processes the details you enter: your name, email address and company, your address if you choose a meeting in person, your notes and the time you pick. It sends a confirmation to you and to us. If you choose Zoom or Google Meet, the meeting link is created through that service.

We use these details only to hold the meeting and prepare for it. Cal.com may store the data in the USA and may set technical cookies of its own inside the booking window. Where data leaves Switzerland, we rely on the safeguards the law requires, such as standard contractual clauses.

AI on this website: the Lab and Ask Rhyline

On the Lab page you can try AI solutions, and on our other pages you can ask the Ask Rhyline assistant about our services. Both run on the Rhyline AI system, which uses Claude, an AI model provided by Anthropic. When you run an example, ask one of the assistants something or analyse an email you paste in, the text involved is sent to Anthropic so that Claude can produce the answer. If you paste a table, Claude receives its column names, a short summary of each column (including some of its values) and the figures it asks for, not the whole table. For the built-in examples this is invented sample data only. For everything else it is whatever you type or paste, so please leave out names, phone numbers, addresses and other personal or confidential details, or replace them with made-up ones.

In the Lab, we do not store what you type or paste, and we do not keep the answers.

Ask Rhyline conversations are kept so that we can improve the assistant: for each question you send, we store the question, the answer, the page you were on and the time. We keep them for 90 days and then delete them automatically. We do not store your IP address or other details about your device with them, and only we can read them. The conversation shown in your chat window is also kept in your own browser for the current visit (session storage) and disappears when you close the tab. If you would like a conversation deleted sooner, contact us and tell us roughly when it took place and what you asked.

To prevent misuse and keep costs under control, we count the number of requests per day, and we keep a short-lived code derived from your IP address (not the address itself) for at most ten minutes, to limit how many requests one visitor can make.

Under its commercial terms, Anthropic does not use this data to train its models and deletes it after a limited period, normally within 30 days, unless it is needed to investigate misuse. Anthropic may process the data in the USA and other countries. Where that happens, we rely on the safeguards the law requires, such as standard contractual clauses.

Who receives your data

We do not sell your data or pass it on for marketing. It is processed by the service providers that run this website and our email: our hosting provider (Hostinger), our email provider (Google), for the AI features on this website Anthropic and, when you book a meeting, Cal.com (and Zoom or Google if you choose one of them for the call). These providers may process data outside Switzerland, for example in the EU or the USA. Where that happens, we rely on the safeguards the law requires, such as standard contractual clauses.

Fonts and images

Fonts and images are served from our own server. Your browser does not contact Google Fonts or other external services to display them.

Your rights

You can ask us at any time which personal data we hold about you, and ask us to correct or delete it, or object to its use. Write to us through the contact form or at the email address above. If you think we have not handled your data correctly, you can contact the Swiss Federal Data Protection and Information Commissioner (FDPIC).

Changes to this policy

We may update this policy when the website or the law changes. The current version is always published on this page.
