Privacy policy

Last updated: November 8, 2026

Faster5K ("we") is operated by Daniel Gnecco. This policy explains what we collect on faster5k.com and why.

Calculators

Every calculator and chart runs in your browser. The times and paces you enter are not sent to us. We do record an anonymous event saying which calculator was used (see Analytics).

Analytics

We use PostHog (US cloud) to understand which pages and tools are useful. Our setup is deliberately minimal:

• No cookies and no localStorage. A random ID is kept in your browser's session storage and disappears when you close the tab.
• We record page views (URL, referrer, screen width), which tool was used and whether a sign-up form was submitted. We never send the email address or the times you type into a calculator to analytics.
• We don't create user profiles, and we don't use analytics for advertising.
• If your browser sends a Global Privacy Control or Do Not Track signal, we don't load analytics at all.

PostHog, like any web service, receives your IP address when your browser connects to it. We don't use it to identify you.

Email sign-ups

Our email list isn't connected yet, so the sign-up and waitlist forms don't currently store anything. When we connect an email provider, we'll update this policy to name it. We'll only use your email to send what you signed up for, every email will include an unsubscribe link, and we'll never sell your address.

Hosting

The site is hosted on Cloudflare, which processes standard request data (such as IP address and browser type) to deliver and protect the site.

Links to other sites

We link to other websites and apps, including the App Store. Their privacy policies apply when you visit them.

Children

This site is intended for adults. We don't knowingly collect personal information from children under 13 (or under 16 in the EEA/UK).

Your rights

Depending on where you live (for example, under GDPR or CCPA), you may have the right to access, correct or delete personal data. Email hello@faster5k.com and we'll respond within 30 days.

Changes

If we change this policy, we'll update the date above.
