Privacy

Last updated: 2 Jul, 2026

Overview

FPS Logger ("the App") is a macOS developer tool created by Stewie Alexander. This privacy policy explains how the App handles data. The App is a sandboxed application distributed via the Mac App Store.

Data Collected

Analytics (Opt-In)

If you opt in to analytics, the following data is sent to a private Google Sheets endpoint each time you test an app with the HUD:

Timestamp
App version
Device model (display name and terminal format)
Operating system version of the tested device
Wireless state (display name and terminal format)
App name tested (display name and terminal format)
App icon URL (fetched from Apple's iTunes Search API)
HUD metric preset used (e.g. Default, Custom, Full)
Whether the App is the free or paid version

No name, email, or other identifying information is included, and the data is not linked to your identity. Analytics collection is opt-in and can be disabled at any time in the App's settings.

App Reports (Optional, User-Initiated)

When you submit a report via the right-click context menu, the following data is sent to the same private Google Sheets endpoint:

App version
Report type (one of: Report Wrong Icon, Report Wrong Name, Report: Not a Game, Report: Metal HUD Supported, Report: Metal HUD Unsupported)
App name (display name and terminal format)
App icon URL
Suggested name (only when submitting a "Report Wrong Name" report)

These reports are submitted only when you explicitly choose to send one.

Support Requests (Optional, User-Initiated)

When you use the in-app Contact Support form, the following is sent to Formspree, a third-party form-handling service, and delivered to the developer by email:

The email address you enter
The message you write
System info: app version, build type, macOS version, and the selected device's model, OS, and connection state
Session logs (only if you leave "Attach session logs" enabled) — up to ~30 KB, which may include names of apps you tested and your Mac's hardware details

This is sent only when you fill in the form and tap Send. Formspree processes the submission under its own privacy policy.

Local Storage

The following data is stored locally on your Mac in the App's sandbox container at ~/Library/Containers/com.stewie.metalhud/Data/Library/Application Support/com.stewie.metalhud/data.json and is never transmitted.

Connected device identifiers, names, and models
Command history (including HUD settings used per session)
Custom app name mappings
App preferences (hidden/pinned apps, window geometry, etc.)
Mac hardware information (model name, chip, memory, macOS version) logged once at launch

App icons are cached locally in ~/Library/Caches/com.stewie.metalhud/icons/.

iCloud Storage

Your saved performance sessions — performance_sessions.json and the individual per-session .fpslog recordings in the PerformanceSessions/ folder — are stored in your iCloud Drive "FPS Logger" folder when iCloud is available on your Mac. This means Apple syncs these files to your own iCloud account and across your signed-in devices. This data stays within your personal iCloud account and is never sent to the developer or any third party. If iCloud is unavailable, these files are kept locally in the App's sandbox container instead.

Data Not Collected

The App does not collect:

Personal information such as your name, phone number, or account credentials. (The App does not collect your email address unless you voluntarily provide it in the Contact Support form — see Support Requests above.)
Location data
Advertising or tracking data

Network Usage

The App makes network requests solely to:

Fetch app icons from Apple's iTunes Search API
Transmit analytics data (opt-in only) to a private Google Sheets endpoint
Transmit user-submitted app reports to a private Google Sheets endpoint
Transmit support-form submissions (email, message, system info, and optional logs) to Formspree when you contact support

No data is shared with third-party advertisers or data brokers.
