Cookies

Last updated: 31 March 2026.

1. Data controller

The controller is the entity identified in the site footer (legal name, address, VAT, e-mail). To exercise your personal data rights, use the contacts in the privacy notice.

2. What cookies and similar technologies are

Cookies are small text files that websites send to your device and store for retransmission on later visits. First-party cookies are set by the site you visit; third-party cookies are set by other domains (e.g. service providers).

This site may also use browser mechanisms such as localStorage to store preferences without sending them to the server. For transparency, they are listed together with cookies in the table below.

3. Types of cookies (classification)

• Strictly necessary / technical: required for the site to work or to carry out a user request (e.g. storing a cookie choice where the law treats it as strictly necessary).
• Functionality: improve usability (e.g. light/dark theme).
• Analytics, marketing or profiling: require consent unless implemented in a strictly anonymous form exempt under applicable guidance; none are active in the published code today.

4. Technologies actually used on this site

The site uses browser localStorage and a cookie banner that records your choice. The published site code does not add first-party analytics or advertising tools.

If an embedded booking calendar is enabled (e.g. via configuration that loads an external service in an iframe), your browser may receive cookies or similar technologies from that provider’s domain. In that case, review the provider’s notice as well and, where appropriate, give consent through the banner (e.g. “Accept all” before using booking) or controls offered by the provider.

Name / key	Type	Purpose	Duration
synapse-cookie-consent	localStorage (first party)	Stores the banner choice: all (accept all, including for any future optional categories) or essential (essential only). Prevents the banner from showing on every visit.	Persistent until you clear site data or the key is changed by the controller
synapse-theme	localStorage (first party)	Stores light/dark theme preference for consistency across pages.	Persistent until you clear site data

5. Legal basis

For technologies strictly necessary to operate the site and to record your cookie choice (where treated as strictly necessary under applicable guidance), the legal bases are pre-contractual measures at your request and/or the controller’s legitimate interests in running the site securely and compliantly, as further described in the privacy notice. Any non-essential categories introduced later will rely on consent where required, collected through the banner or another appropriate mechanism.

6. Managing or withdrawing preferences

• Browser settings: clear site data / local storage for this origin and reload — the cookie banner will appear again.
• Browser help: use your vendor’s documentation (Chrome, Firefox, Safari, Edge, etc.) to block or delete cookies and manage per-site storage.
• “Essential only” button: stores essential so optional tools are not enabled later without fresh consent.

7. Third-party cookies

In addition to the first-party technologies listed in the table, third-party cookies or equivalents may appear when you use embedded external services (e.g. a Cal.com / Calendly-style scheduling widget). Those tools are managed by their providers; purpose, cookie types and opt-out are described in their notices. We do not add separate third-party advertising or analytics scripts beyond what the scheduler provider may set when the embed is configured.

8. Your rights and further information

For rights of access, rectification, erasure, restriction, objection, portability and complaints to a supervisory authority, see the privacy notice.
