Network Atlas Privacy Policy

Network Atlas is a network discovery application for macOS developed by Zarware. This privacy policy explains how Network Atlas handles your information and is specific to this application only.

The Short Version

Network Atlas is designed with privacy in mind. The app operates primarily on your device. The only data transmitted externally is MAC addresses, which are sent to our server solely to identify device manufacturers. We do not collect, store, or sell your personal information.

1. Information We Collect

Information Transmitted to Our Servers

Data Type	What It Is	Why We Collect It
MAC Addresses	Hardware identifiers of network devices	To identify device manufacturer/vendor

How it works

When Network Atlas discovers a device on your network, it may send that device's MAC address to our API (zarware.com/api/mac-lookup/) to look up the manufacturer name (e.g., "Apple", "Samsung", "Dell"). This helps you identify devices on your network.

What We DO NOT Collect

Your name, email, or contact information
Your IP address or location
Device names or hostnames
Network passwords or credentials
Browsing history or app usage data
Any other personal information

Information Stored Locally on Your Device

The following data is stored only on your Mac and is never transmitted to our servers:

Data Type	Purpose	Storage Location
Discovered device information	Display network devices	App memory (cleared on quit)
Custom device names	Your labels for devices	macOS UserDefaults
App preferences	Scanner settings	macOS UserDefaults

2. How We Use Information

MAC Address Lookups

Purpose: Identify the manufacturer of network devices
Process: MAC address is sent via HTTPS to our API, manufacturer name is returned
Retention: We do not store MAC addresses. Lookups are transient and processed in real-time
No Logging: Our API does not log or retain the MAC addresses it receives

Local Data

All other data discovered by Network Atlas (IP addresses, hostnames, services, ports) remains on your device and is never transmitted externally.

Third-Party Services

Network Atlas uses one external service:

Service	Data Shared	Purpose
Zarware MAC Lookup API	MAC addresses only	Device manufacturer identification

What We Do NOT Do

No advertising networks — We do not use any advertising SDKs
No analytics platforms — We do not use analytics or tracking tools
No data brokers — We do not sell or share data with data brokers
No third-party tracking — We do not track you across apps or websites

4. Data Retention

Data Type	Retention Period
MAC addresses sent to our API	Not retained — processed in real-time only
Discovered network data	Cleared when app quits
Custom device names	Until you delete them or uninstall the app
App preferences	Until you reset them or uninstall the app

5. Data Security

We implement appropriate security measures to protect data transmission:

HTTPS/TLS encryption for all API communications
No sensitive data storage on our servers
Local data protection via macOS security features (sandboxing, Keychain)

6. Your Rights and Choices

Control Your Data

Action	How To
Delete custom device names	Remove in app or delete via app preferences
Clear all local data	Uninstall Network Atlas
Opt out of MAC lookups	Disable network scanning features
