What data we collect and why

We collect the minimum personal data necessary to operate this site.

  • Email enquiries: when you write to us at info@syntrociety.com or hello@syfers.eu, we receive your email address and the content of your message. We use this only to respond to your enquiry. Legal basis: legitimate interest (Article 6(1)(f) GDPR).
  • Analytics: we use Plausible Analytics, a privacy-first analytics service hosted in the European Union. Plausible does not use cookies, does not store IP addresses, and does not track individuals across sites. It provides anonymised, aggregated data about page visits. Legal basis: legitimate interest (Article 6(1)(f) GDPR). No consent required.
  • Hosting: the site is hosted on Vercel. Vercel processes server request data (including IP addresses) as part of normal site operation. See Vercel’s privacy policy at vercel.com/legal/privacy-policy.

What we do not collect

syfers.eu does not use cookies. There is no tracking, no advertising, no user accounts, no newsletter subscription, and no payment processing on this site.

Data retention

Email enquiries are retained as long as the correspondence is relevant, and deleted when it is no longer needed. We do not retain enquiries beyond two years.

Plausible Analytics data is anonymised and aggregated at collection. No individual data is retained.
