Privacy policy

We only collect personal data (name, email, phone number, the content of your message) if you send it to us: by writing to us, calling us, subscribing to the newsletter or sending us a job application. Providing it is optional, but without it we cannot reply to you.

We only use it to reply to you, to send you the newsletter if you asked for it, or to process your application. We never sell it or pass it on to third parties.

We rely on your consent for the newsletter, on our pre-contractual exchanges for project enquiries and applications, and on our legitimate interest for other messages.

We keep this data for 2 years after our last exchange, until you unsubscribe from the newsletter, and for 6 months after the end of a recruitment process. Documents related to an engagement are kept for 10 years, as required by Swiss law.

We use Fathom Analytics (Conva Ventures Inc., Canada) to measure traffic on the site, based on our legitimate interest in improving it. Fathom does not set any cookies and does not keep any data that could identify you: your IP address is anonymised immediately and the statistics (pages viewed, referrer, device type, country) are only ever aggregated.

A cookie is a small file stored on your device when you visit a site. Apart from the one that remembers your choice in the cookie banner, we only set cookies with your consent.

With your consent, we use Contentsquare (formerly Hotjar, Content Square SAS, France) to anonymously analyse how the site is browsed (clicks, scrolling) and improve its usability. Its cookies are kept for up to one year and the data collected is deleted after 365 days.

You can accept or decline these cookies in the banner, then change your mind at any time via the “Manage cookies” link at the bottom of the page. Declining them does not prevent you from browsing the site.

Your data is only accessible to the twks team and to the technical providers that run the site: our host Infomaniak (Switzerland), Fathom, Contentsquare and our newsletter tool Mailchimp (Intuit Inc., United States). They are bound by a data processing agreement.

This data may be processed in Switzerland, in the European Union (notably in Ireland) and in Canada, countries recognised as offering an adequate level of protection. When a provider processes it in the United States (notably Mailchimp), the transfer is governed by the European Commission's standard contractual clauses or by the Data Privacy Framework.

You can ask at any time to access your data, have it corrected or deleted, restrict its use, object to its processing, receive it in a common format or withdraw your consent. Simply write to hello@twks.ch; we reply within 30 days.

If you believe your rights have not been respected, you can contact the Federal Data Protection and Information Commissioner (FDPIC) in Switzerland, or the data protection authority of your country of residence in the EU (in France, the CNIL).

We may change this policy, for example if we add a tool to the site. The version published here is the authoritative one.
