This privacy notice explains how Olthos (“we”, “us”) processes personal data in connection with the website olthos.ch and related private training and coaching enquiries. It is prepared under the Swiss Federal Act on Data Protection (nFADP / revDSG). Where the EU General Data Protection Regulation (GDPR) also applies (for example to visitors in the EEA/UK), we apply equivalent standards.

  • Enquiry datayou submit via the consultation form: name, email address, phone number (optional), location (optional), preferred contact method, and the content of your message (including training objectives or other information you choose to share).
  • Communication datafrom emails, calls or messages exchanged when we respond to an enquiry or deliver services.
  • Client and coaching dataneeded to plan and deliver personal training or nutrition coaching (for example goals, schedule preferences, session notes), if you become a client.
  • Technical datasuch as IP address, browser and device information, pages visited, referrer, and timestamps, generated when you use the website.
  • Cookie and similar technology dataas described in ourCookie Policy.

Please do not submit more sensitive information than needed for your enquiry. If you voluntarily include health-related details (for example injuries, medical conditions or body composition goals), we treat that information with particular care and use it only to assess and respond to your request or to deliver agreed coaching.

3. Purposes and legal grounds

We process personal data for the following purposes:

  • to operate, secure and improve the website;
  • to receive and respond to consultation and contact enquiries;
  • to prepare, conclude and perform coaching or training agreements;
  • to manage client relationships, scheduling and related administration;
  • to comply with legal obligations (for example accounting or tax requirements where applicable);
  • to establish, exercise or defend legal claims;
  • to manage cookie preferences and measure or improve site use where allowed under cookie consent rules.

Under Swiss law, processing is justified in particular by:

  • your consent (for example optional form fields, non-essential cookies, or marketing if you opt in);
  • the conclusion or performance of a contract with you, or pre-contractual steps at your request;
  • an overriding private interest (for example website security, fraud prevention, efficient business communication);
  • a legal obligation, where applicable.

Where GDPR applies, the corresponding bases are typically Art. 6(1)(a) consent, Art. 6(1)(b) contract / pre-contractual steps, Art. 6(1)(c) legal obligation, and Art. 6(1)(f) legitimate interests. Health-related details you volunteer may also rely on your consent or on necessity for health/fitness services you request, as applicable.

4. Where data comes from

Most data comes directly from you (forms, emails, calls, sessions). Technical and cookie data are collected automatically when you visit the site, subject to your cookie choices.

5. Recipients and processors

We do not sell personal data. Data may be accessed by João Oliveira / Olthos and, where necessary, by trusted service providers acting on our instructions, such as:

  • website hosting and infrastructure providers;
  • content management and form software (including WordPress and Fluent Forms);
  • cookie consent and compliance tooling (including Complianz);
  • email or communication providers used to reply to enquiries;
  • professional advisers (legal, accounting) when required.

These parties process data only as needed to provide their services and under appropriate confidentiality and data-protection arrangements.

6. Disclosure abroad

Our primary operations are in Switzerland. Some providers may process data in other countries, including the EU/EEA or further afield. Where personal data is transferred to a country without an adequate level of protection recognised by Swiss authorities, we use appropriate safeguards (for example standard contractual clauses) or rely on another lawful transfer mechanism, unless an exception under the nFADP applies.

7. Retention

We keep personal data only as long as needed for the purposes above:

  • Website enquiries:typically for the time needed to handle your request and for a reasonable follow-up period (usually up to 24 months after the last relevant contact), unless a longer retention is required or justified.
  • Client records:for the duration of the coaching relationship and thereafter as needed for administration, accounting, or legal claims (often several years under Swiss commercial practice).
  • Technical logs:for short periods needed for security and operation, unless a longer period is required to investigate incidents.
  • Cookies:according to the periods set out in theCookie Policy.

When retention is no longer necessary, we delete or anonymise the data.

8. Cookies and similar technologies

We use cookies and similar technologies as described in our Cookie Policy (EU). Essential cookies are needed for the site to function. Non-essential cookies (for example analytics or marketing) are used only with your consent where required. You can change or withdraw cookie consent via the cookie settings provided on the site.

9. Your rights

Subject to the conditions of the nFADP (and GDPR where applicable), you may request:

  • information about whether we process your personal data and access to it;
  • correction of inaccurate data;
  • deletion of data;
  • restriction of or objection to certain processing;
  • withdrawal of consent for the future, where processing is based on consent;
  • data portability / delivery of data, where provided by applicable law.

To exercise these rights, contact us via the contact form. We may need to verify your identity before responding. You also have the right to lodge a complaint with the Swiss Federal Data Protection and Information Commissioner (FDPIC / EDÖB). If GDPR applies to you, you may additionally complain to your local supervisory authority.

We take appropriate technical and organisational measures to protect personal data against unauthorised access, loss, alteration or disclosure. No online transmission or storage can be guaranteed fully secure; please use the website and email carefully.

11. Children

The website and private coaching services are directed at adults. We do not knowingly collect personal data from children for marketing or online services. If you believe a child has provided us with personal data, please contact us so we can delete it where appropriate.

12. No automated individual decisions

We do not use fully automated decision-making that produces legal or similarly significant effects for you based solely on automated processing.
