Privacy policy

Who we are

carbsperhour.com is operated by Thomas Neumann (full postal address on the Impressum page). The site is a free, informational fueling calculator. There are no accounts, no payments, and no commercial transactions in v1.

What we collect

• Session cookie (PHPSESSID). Strictly necessary. Expires when you close your browser. The session exists solely to hold a CSRF token that prevents forged form submissions (e.g. when saving a short-link plan). It is not used for tracking, advertising, or any cross-site activity.
• Saved plans (optional). If you click "Save short link" on the calculator, your calculator inputs (duration, target g/h, ratio, ingredient selection, carriers, sodium, water) are stored in our database against a random token. No IP address, email, or other personal identifier is stored alongside the plan.
• Server logs. Standard request logs capture IP address, User-Agent, request path and timestamp. Retention is roughly 30 days. Legal basis: Art. 6(1)(f) GDPR — legitimate interest in operating and securing the service.
• Browser localStorage. Your theme preference (cph_theme) and any gel reference price / ingredient cost overrides you edit on the calculator are stored in your browser. This data never leaves your device.

What we don't collect

No analytics. No Google services. No third-party trackers (no Plausible, no Matomo, no PostHog, no Umami, no Facebook pixel). No advertising cookies. No accounts. No email collection in v1. No payment data.

Third parties

• Hosting: Hetzner Cloud GmbH, Gunzenhausen, Germany. Covered by a data-processing agreement (AVV) under Art. 28 GDPR.
• Email delivery: not active in v1. When a contact form or transactional email is added, the SMTP provider will be disclosed here.

Cookies

The only cookie this site sets is PHPSESSID, which is strictly necessary per § 25 (2) TTDSG and does not require consent. No consent banner is shown because there is nothing optional to consent to.
