Privacy Policy

Last updated: February 18, 2026

Lawn Measure ("we", "our", or "the app") is a free web application that helps homeowners measure their lawn area using GPS and calculate lawn care product needs. Your privacy is important to us. This policy explains what data we collect, how we use it, and your rights.

1. Information We Collect

Location Data (GPS)

When you use the measurement feature, the app requests access to your device's GPS to record your walking path. This location data is used solely to calculate the perimeter and area of your lawn.

GPS coordinates are processed entirely on your device.
Location data is never transmitted to our servers or any third party.
Saved measurements are stored locally in your browser's localStorage.

Locally Stored Data

The app stores the following data locally on your device using browser localStorage:

Saved lawn measurements (name, area, perimeter, GPS coordinates)
Your preferred unit system (metric or imperial)

This data never leaves your device. You can delete it at any time by clearing your browser data or by using the delete function within the app.

2. Third-Party Services

Google AdSense

We use Google AdSense to display advertisements. Google may use cookies and web beacons to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your browsing activity.

You can opt out of personalized advertising by visiting Google Ads Settings.
You can opt out of third-party vendor cookies at aboutads.info.

For more information, please review Google's Privacy Policy.

Leaflet / OpenStreetMap

The app uses the Leaflet mapping library with OpenStreetMap tiles to display maps. When a map is shown, your browser loads map tiles from OpenStreetMap servers. Please refer to OpenStreetMap's privacy policy for details.

3. Cookies

Lawn Measure itself does not set cookies. However, third-party advertising services (Google AdSense) may place cookies on your device. You can manage cookie preferences through your browser settings.

4. Data Security

Since all measurement data is stored locally on your device, it is protected by your device's own security measures. We do not operate servers that store your personal data.

5. Children's Privacy

Lawn Measure is not directed at children under 13. We do not knowingly collect personal information from children. The app is a general-purpose utility tool intended for homeowners and lawn care professionals.

6. Your Rights

You have the right to:

Access your data at any time (it is stored locally on your device)
Delete your data by clearing browser storage or using the in-app delete feature
Export your data using the app's JSON export feature
Opt out of personalized ads through Google's ad settings

7. Changes to This Policy

We may update this privacy policy from time to time. Any changes will be posted on this page with an updated revision date. Continued use of the app constitutes acceptance of the revised policy.
