Privacy Policy & Zero-Telemetry Guarantee

1. Fastfetch CLI Software: Zero-Telemetry Guarantee

When you install and execute the fastfetch command-line utility on your computer (Linux, macOS, Windows, FreeBSD, Android, etc.):

• No Data Collection: Fastfetch queries local kernel interfaces (sysfs, procfs, sysctl, IOKit, Win32 registry, WMI) strictly in memory. None of your hardware specifications, usernames, hostnames, IP addresses, or disk serial numbers are ever recorded to external storage or sent over the network.
• No Phone-Home or Analytics: The binary contains zero tracking libraries, zero crash report uploaders, zero telemetry beacons, and zero automatic update checkers.
• Air-Gapped Operation: Fastfetch executes 100% offline without requiring internet access. The only network-related modules (e.g. publicip or weather) are disabled by default and will only make an outbound request if explicitly added to your configuration file by you.

2. Website Data Handling (https://fastfetch.dev)

The website https://fastfetch.dev is designed as a static, privacy-first technical resource:

• No Tracking Cookies: We do not use marketing cookies, tracking pixels, or cross-site fingerprinting scripts.
• No Third-Party Advertising: There are zero commercial advertising networks, ad trackers, or sponsored retargeting tags on this website.
• Standard Server Logs: Like all web servers, standard HTTP access logs (IP address, user agent, requested URL, and timestamp) may be temporarily processed by edge Content Delivery Networks (e.g. Cloudflare / GitHub / Vercel) strictly for DDoS mitigation, caching, and server security. These logs are not sold, leased, or linked to individual personal identities.
• Local Storage Usage: Any preferences saved in your browser (such as your active shell tab or config generator presets) are stored strictly inside your browser's local storage and are never uploaded to any remote server.

3. AI Agent & Crawler Accessibility

In accordance with emerging Agentic Web (AX) standards, https://fastfetch.dev publishes public machine-readable indexes (llms.txt, AGENTS.md, and sitemap.xml) and implements HTTP content negotiation per acceptmarkdown.com specifications (serving clean text/markdown representations via Vary: Accept headers). Automated AI coding assistants and search crawlers are permitted to index and query these resources subject to our published robots.txt policy.

4. Open Source Transparency & Source Auditing

Because Fastfetch is 100% open source under the MIT License, every line of C source code is publicly auditable. You can verify our zero-telemetry claims directly by inspecting the upstream repository at github.com/fastfetch-cli/fastfetch.
