The short version
fadr collects zero user data. It has no analytics, no telemetry, no crash reporters, no advertising SDKs, and no network code. It does not know your name, your email, or that you exist at all. Your settings live on your Mac and never leave it.
If you want the detail, the rest of this page explains every nook and cranny.
What the app does on your device
fadr listens for touch events on your trackpad using Apple's public Multi-Touch framework. It needs Accessibility permission to do this. Every touch event is processed locally and then immediately discarded. Nothing is logged to disk, nothing is aggregated, nothing is uploaded.
What is stored on your Mac
Your preferences live in a standard macOS plist file at:
~/Library/Preferences/llc.valid.fadr.plist
This file contains:
- The action assigned to each trackpad edge
- Your sensitivity and haptic preferences
- A list of your per-app profiles
- Launch-at-login and menu-bar-icon toggles
That's the entire database. No identifiers, no timestamps, no usage counts.
Network activity
The app does not contain an HTTP client. The only time fadr touches the network is when you manually check for updates via the Preferences window, which calls a single static JSON file on our server to see whether a newer version exists. That request includes no identifying information beyond what any HTTP request carries (your IP address and the user-agent string), and we do not log it.
Purchases and licensing
Purchases are handled by Lemon Squeezy, our merchant of record. When you buy fadr, Lemon Squeezy processes your payment and sends you a license key by email. We receive the email address attached to the purchase so we can deliver support, but we do not send marketing to it and we do not share it with anyone. Lemon Squeezy's own privacy policy applies to the checkout experience.
Your license key
When you enter your license key in the app, it is validated against a stateless endpoint that returns a yes/no. We log nothing about this check. The key itself is stored in the macOS Keychain.
Email support
If you email us at hello@fadr.app, your message is stored in our email provider for as long as the conversation is active, then archived. We never share the content of a support email with anyone outside the company.
Children's privacy
fadr is a trackpad utility and not directed at children. Because we collect no data from anyone, we collect none from children either.
Changes to this policy
If we ever change how fadr handles data - for example, adding an opt-in telemetry flag in a future release - we will update this page and note the change in the release notes for that version. We will never switch data collection on by default.
