Privacy

Short version

Prompt Enhancer is a desktop app for macOS, Windows and Linux that runs entirely on your device. We don't have a server that sees your prompts. We don't have user accounts. We don't track you.

What stays on your device

• Your selected text and the enhanced output — OS credential store + local SQLite, never uploaded.
• Your Anthropic API key (BYOK mode) — macOS Keychain, Windows Credential Manager, or libsecret/GNOME Keyring on Linux.
• Your preset choices and settings — local UserDefaults / Tauri store.

What is sent off your device

BYOK mode (default): your prompt goes directly to api.anthropic.com over TLS. We're not in the loop. Anthropic's privacy policy applies.

Managed mode (Lifetime Pro): your prompt goes to our Cloudflare Worker proxy at api.promptenhancer.online, which forwards it to Anthropic. We log only: timestamp, prompt length (tokens), and your license key. We do not log the prompt content. Logs retained 30 days for abuse detection.

Website analytics

This marketing site uses Vercel Analytics — privacy-friendly, no cookies, no cross-site tracking, no personal identifiers. Aggregate page views only.

Updates

The app checks github.com/promptenhancer/releases for new versions — Sparkle on macOS, Tauri updater on Windows/Linux. Standard HTTPS request, no telemetry payload attached.
