Privacy Policy for WiFi Checkup
Effective Date: October 24, 2026
WiFi Checkup (“the App,” “we,” “our,” or “us”) helps users understand their Wi-Fi and internet connections, diagnose performance issues, and find practical ways to improve connectivity.
We respect your privacy and aim to minimize the information processed when you use the App.
1. Information We Process
WiFi Checkup processes certain technical information to evaluate your network connection and provide diagnostic results.
Depending on the features you use, this information may include:
• Internet connection type (Wi-Fi or cellular)
• Local IP address, router address, and network configuration
• Router identification information, where available
• Network performance measurements, including download speed, upload speed, latency, and packet loss
• DNS lookup performance
• Information about devices detected on your local network, such as device names and network addresses, when available
• Diagnostic results, room labels, and previous network checks
• Information needed to compare Wi-Fi and cellular performance
This information is used to perform the diagnostic functions you request.
WiFi Checkup does not require you to create an account to use its core diagnostic features.
2. Local Data Storage
The App saves diagnostic history on your device so you can:
• Review previous network checks
• Compare network performance over time
• Identify recurring connection problems
• Compare results across different rooms
• Evaluate whether troubleshooting steps improved your connection
Diagnostic history is stored locally on your device.
The App does not require you to upload your saved diagnostic history to a WiFi Checkup account.
You may be able to remove saved diagnostic information through the App's available history controls. Removing the App generally removes its locally stored app data, subject to iOS backup and restore behavior.
3. Internet Speed Tests and Third-Party Services
To measure internet performance, WiFi Checkup communicates with external network testing services.
Cloudflare
The App uses Cloudflare services for internet speed and connectivity measurements.
When tests are performed, Cloudflare may receive technical connection information, including your public IP address, according to Cloudflare's applicable privacy practices.

Measurement Lab (M-Lab)
The App also supports optional Measurement Lab speed tests.
M-Lab testing is not enabled by default. If you select this service, test measurements and your public IP address may be included in publicly available M-Lab measurement data.
Please review M-Lab's privacy practices before enabling this option:

WiFi Checkup does not control how these independent services process information they receive.
4. Local Network Access
WiFi Checkup may request permission to access your local network.
This permission supports functionality such as identifying your router, evaluating communication with it, and discovering compatible devices on your local network.
You can manage this permission in your iPhone's Settings.
If you deny access, some diagnostic functions may be limited.
5. Cellular Network Diagnostics
When using cellular diagnostics or Wi-Fi-versus-cellular comparison features, the App may measure connection performance over your cellular network.
Speed tests can consume mobile data. The App provides controls and limitations intended to reduce unnecessary data usage.
WiFi Checkup does not require access to your cellular carrier account credentials.
6. Diagnostic Reports and Sharing
WiFi Checkup allows you to generate and share diagnostic information, including reports.
Reports may contain technical network measurements, router details, and other diagnostic information.
Sharing is initiated by you using the available sharing features.
Before sharing a report, review its contents to ensure you are comfortable disclosing the included information.
Any information you share with another person or service is subject to that recipient's privacy practices.
7. How Information Is Used
The App processes network information to:
• Diagnose potential connectivity and performance problems
• Explain diagnostic findings in understandable language
• Recommend troubleshooting steps
• Compare current and previous network measurements
• Evaluate application and gaming connection performance
• Generate diagnostic reports requested by users
The App does not need your contacts, photos, or precise GPS location to perform its documented core diagnostic features.
8. Data Sharing and External Connections
WiFi Checkup communicates with external network endpoints as necessary to perform user-requested connectivity checks.
These services may observe connection metadata, including public IP addresses, as part of normal internet communications.
Locally stored diagnostic history is not automatically shared with other WiFi Checkup users.
We do not sell locally stored diagnostic history.
9. Data Retention
Diagnostic records stored locally remain on your device until removed through available app functionality, app deletion, or device-level data management.
External measurement services may retain information according to their own data-retention policies.
10. Security
We use iOS platform capabilities and established network protocols to support the App's operation.
However, no device, network connection, or electronic storage system can be guaranteed completely secure.
Users should avoid sharing diagnostic reports containing sensitive network details with untrusted recipients.
11. Children's Privacy
WiFi Checkup is a general-purpose network utility and is not specifically directed toward children.
The App's core functions do not require users to provide their name, email address, or account registration information.
If you believe personal information has been collected inappropriately, please contact us using the information below.
12. Your Privacy Choices
You can:
• Control Local Network access through iOS Settings
• Choose whether to use optional M-Lab testing
• Control whether cellular speed testing is performed
• Choose whether to export or share diagnostic reports
• Remove locally stored app data by deleting the App, subject to device backup behavior
13. Changes to This Privacy Policy
We may update this Privacy Policy to reflect changes to App functionality, third-party services, or legal requirements.
Any updated version will be published at the Privacy Policy URL with a revised effective date.
