Introduction
Thank you for using SignalMap (“the App”). SignalMap uses your iPhone’s LiDAR and camera to scan your home’s floor plan and maps the Wi‑Fi signal quality in each area as you walk around.
We value your privacy. This policy explains how the App handles your information.
Data Collection and Use
We explicitly state: This App does not collect, store, or share any of your personal information with any third parties.
- On-device processing: All scanning and analysis happen entirely on your device. The floor plan generated from LiDAR/camera and the resulting signal heatmap are processed locally and are never uploaded to us or anyone else.
- Network measurements: To estimate Wi‑Fi quality, the App measures the connection (latency, jitter, packet loss) between your device and your own router/gateway on the local network. These measurements are performed on your device and stay on your device. The App does not capture or transmit the contents of your network traffic.
- Wi‑Fi network name (SSID/BSSID): With your permission, the App reads the name and identifier of the Wi‑Fi network you are currently connected to, solely to label nodes on the heatmap. This information is used locally and is not transmitted.
- Local storage: Your scan history is saved only in your device’s local storage so you can review past results. You can delete any record at any time within the App.
- No backend services: There is no developer-operated server. We have no access to your floor plans, scans, network data, or usage.
- No analytics or tracking: The App contains no third-party analytics, advertising, or tracking SDKs, and does not track you across apps or websites.
Permissions
The App requests the following permissions, each used only for the stated purpose:
- Camera — required by Apple’s RoomPlan/ARKit to scan rooms with LiDAR and build the floor plan.
- Local Network — to measure connection quality to your router/gateway.
- Location (While Using the App) — required by iOS in order to read the name (SSID) of the Wi‑Fi network you are connected to, used to label the heatmap. The App does not use your location for any other purpose and does not store or share it.
Purchases
Optional “Pro” features are offered through in-app purchases and subscriptions processed by Apple via the App Store. Payments are handled entirely by Apple under its own terms and privacy policy; we do not receive or store your payment information. Subscription status is verified through Apple’s StoreKit.
Children’s Privacy
The App is not directed at children and does not knowingly collect any information from anyone.
Changes to This Privacy Policy
Although we do not currently collect any data, we will update this privacy policy if the App’s functionality changes significantly in the future (for example, introducing features that require cloud support). Any changes will be posted on this page with an updated “Last Updated” date.
If you have any questions about this privacy policy or concerns about the security of the App, please contact us at:
