Cookie Policy

Last updated: 5 August 2026

This Cookie Policy explains how Nanotam (RDI Cordier, St-Prex, Vaud, Switzerland) (“we”, “us”, “our”) uses cookies and similar technologies on our websites, landing pages and, where applicable, in our applications (the “Service”).

It should be read together with our Privacy Policy, which describes how we process personal data more broadly under the Swiss Federal Act on Data Protection (FADP), the EU GDPR where it applies, and related ePrivacy rules.

1. What are cookies and similar technologies?

Cookies are small text files stored on your device when you visit a website. We also use similar technologies such as pixels, tags, local/session storage, SDKs, scripts and device/browser identifiers (together, “cookies” in this Policy).

Cookies may be:

• Session cookies — deleted when you close your browser; or
• Persistent cookies — stored for a defined period or until you delete them;
• First-party — set by Nanotam; or
• Third-party — set by our partners (for example analytics providers).

2. How we use cookies

We use cookies to:

• operate and secure the Service (login/session, load balancing, fraud prevention);
• remember preferences and consent choices;
• measure traffic, performance and engagement in detail (pages viewed, events, funnels, acquisitions, device/tech data);
• understand product usage and improve features, content and campaigns;
• attribute visits to marketing channels and, where enabled, support advertising / remarketing;
• diagnose errors and monitor availability.

3. Categories of cookies

3.1 Strictly necessary

Required for the Service to function (security, network management, load balancing, consent storage, essential account/session features). These do not require consent. Without them, parts of the Service may not work.

3.2 Preferences / functional

Remember choices such as language, UI settings or previously entered information to improve your experience. Where required by law, we place these only after you consent.

3.3 Analytics & performance

Help us understand how visitors and users interact with the Service — including page views, clicks, scrolls, session duration, referral sources, approximate location derived from IP, device/browser type, and custom events we define for product analytics. We use these insights to improve Nanotam and our communications.

These cookies are used on the basis of your consent where required (in particular for visitors in the EU/EEA/UK and where Swiss rules or best practice require it). You can refuse or withdraw consent at any time without affecting access to core content, though we will have less visibility into usage.

3.4 Marketing & advertising

Used to measure campaign effectiveness and, if enabled, to deliver or personalise ads on our sites or third-party platforms (including remarketing audiences). Placed only with your consent where required.

4. Google Analytics and other analytics tools

We may use Google Analytics (including Google Analytics 4) and/or comparable analytics products (for example product-analytics or error-monitoring tools) to collect and analyse usage information.

When Google Analytics is enabled:

• Google may set cookies and process identifiers, device/browser data, on-site events and approximate location;
• we configure Analytics to support privacy controls available to us (such as IP anonymisation / redaction options, data-retention settings, and Google Consent Mode where implemented);
• Google acts as a service provider / processor for Analytics data we collect for our purposes, under Google’s terms and our configuration;
• data may be processed on servers outside Switzerland / the EEA (including in the United States). International transfers are covered by appropriate safeguards described in our Privacy Policy (for example Standard Contractual Clauses and any applicable transfer frameworks);
• Analytics is loaded for non-essential measurement only after consent, where consent is required.

Learn more in Google’s Privacy Policy and Google Analytics data protection information. You may also use Google’s browser opt-out add-on where available, in addition to our consent controls.

We may use additional analytics, tag-management, A/B testing or monitoring tools that collect similar categories of data. Where those tools are non-essential, they are subject to the same consent approach.

5. Examples of cookies we may use

The exact cookies can change as we improve the Service. Typical examples include:

• Consent / preference cookies — store your cookie choices (necessary for compliance);
• Session / security cookies — keep you signed in or protect forms;
• Google Analytics cookies (e.g. identifiers such as _ga, _ga_*) — distinguish users/sessions and measure events (analytics; consent where required);
• Marketing / ads cookies — from advertising or social platforms if campaigns are active (consent where required).

A current list may also be shown in our cookie banner or preference centre when available.

6. Legal bases

• Strictly necessary cookies — our legitimate interest in operating a secure, functional Service, and/or necessity to provide a service you request;
• Analytics, functional (non-essential) and marketing cookies — your consent, where required by applicable law. You may withdraw consent at any time.

Where cookies involve personal data, our Privacy Policy applies, including your rights of access, erasure, objection and complaint to a supervisory authority (e.g. the Swiss FDPIC or an EU DPA such as the CNIL).

7. Managing your preferences

You can control cookies by:

• Our cookie banner / preference centre — accept, refuse or customise non-essential categories on first visit (or when consent is reset);
• Browser settings — block or delete cookies (see your browser help pages). Blocking all cookies may break necessary features;
• Device / OS permissions — for in-app tracking or identifiers, where applicable;
• Google Analytics opt-out — browser add-on or Google account ad settings, where relevant.

Withdrawing consent does not affect the lawfulness of processing based on consent before withdrawal. Strictly necessary cookies will continue to operate.

8. Retention

Cookie lifetimes vary: session cookies expire when you close the browser; persistent cookies last from a few days up to 24 months (or longer if a specific tool requires it and this is disclosed in the preference centre). Analytics retention in our Google Analytics property is configured in line with our operational needs and privacy settings.

9. Do Not Track / Global Privacy Control

Browser “Do Not Track” signals are not consistently standardised. Where we implement a consent framework, your choices in our banner / preference centre (and any legally recognised opt-out signals we support) take priority.

10. Changes

We may update this Cookie Policy when our tools or legal requirements change. The “Last updated” date will be revised accordingly. Significant changes may also be highlighted in the Service or cookie banner.
