WiFi Heatmap Privacy Policy
Last updated: 28 October 2026
WiFi Heatmap is made by Kiwilytics. This policy explains what the app does with your information. The short version: WiFi Heatmap doesn't collect any personal data. Your scans stay on your phone.
What WiFi Heatmap doesn't do
- No account or sign-in.
- No analytics, advertising or tracking of any kind.
- No third-party code that collects data.
- We never see your scans, your location or anything about you.
What stays on your phone
- Scans and places. Readings, scores, the names you give places and where each reading was taken in the room are stored on your iPhone only. Scans you don't save as a place are deleted after 30 days. Deleting a place or the app removes them. If you back up your iPhone to iCloud or a computer, Apple includes them in that backup like any other app data.
- Settings. If you type in your router's address, it's saved on your phone.
Camera
WiFi Heatmap uses the camera through Apple's ARKit to track where you walk, so each reading can be pinned to the right spot in the room. Camera images are processed on your phone as you scan. They're never saved or sent anywhere.
Network tests
To measure your connection, WiFi Heatmap sends test traffic:
- To your Wi-Fi router, over your local network, to tell weak Wi-Fi apart from slow internet. This is why iPhone asks for Local Network access.
- To 1.1.1.1, Cloudflare's public internet address, to measure latency (how long a reply takes).
- To our speed test server, which runs on Cloudflare. It sends and receives blank test data to measure download and upload speed. When the app opens, it also asks this server whether its version is still supported, sending only the version number.
Like any server on the internet, these services see your IP address while answering a test. Our speed test server doesn't store or log anything about you. Cloudflare's handling of network traffic is covered by Cloudflare's privacy policy.
Mobile data
Scans can measure your cellular connection. Streaming tests download small test files over cellular, up to about 30 MB per minute of walking, and WiFi Heatmap asks before each streaming walk that does this. On cellular, Test Speed Here downloads and uploads up to about 60 MB per test, and WiFi Heatmap asks before the first one in each walk. Your carrier may count this toward your data plan.
Children
WiFi Heatmap doesn't collect personal data from anyone, including children.
Changes
If this policy changes, we'll update this page and the date at the top.
