What cookies we use (if any) and how to control them.
Pronix is a static website. We do not use tracking cookies or advertising cookies. For aggregate visit statistics, our self-hosted Matomo instance sets two small first-party cookies — DNT is honored server-side, the IP is /16-anonymized. Alongside that there are two strictly-necessary technical cookies for language preference and theme.
| Cookie | Purpose | Lifetime |
|---|---|---|
| Language preference | Remembers your chosen UI language between visits | Up to 1 year |
| Theme (light/dark) | Remembers your chosen color theme | Up to 1 year |
_pk_id.3.* | Matomo visitor ID (first-party, no personal identifier) | ~13 months |
_pk_ses.3.* | Matomo session cookie (first-party) | 30 minutes |
All of these are first-party, set only by this site, and contain no personal identifier. The first two are technically necessary. The Matomo cookies rely on legitimate interest (GDPR Art. 6 (1) f) — since DNT is honored server-side, the IP is anonymized, and there is no cross-site reach, the setup is minimally invasive and, by common supervisory-authority practice, does not require prior consent.
The site loads no third-party scripts that could set cookies on their own behalf. No CDN-hosted analytics, no embedded videos from tracking platforms, no chat widgets.
Matomo cookies are only set if your browser does not send the
Do-Not-Track header. DNT enabled → no tracking, no Matomo
cookies. If you want to opt out anyway: block the Matomo
domain (stats.pronix.info) in your browser, or delete the
cookies manually — every browser offers controls for this
under “Settings → Privacy” or equivalent.
We may update this policy. The lastmod date at the top of the
file reflects the most recent change. Material changes will be
noted prominently on the site for a reasonable period.
