Privacy Policy

At LawnIndex, we take your privacy seriously. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application. The app does not require you to create an account or provide an email address. It signs you in with an anonymous identifier so your scans and preferences stay with you on your device.

4. Data Storage and Security

We implement industry-standard security measures to protect your data:

• All data is encrypted in transit using SSL/TLS.
• Database information is encrypted at rest.
• Uploaded photos are stored in secure, private cloud storage accessible only through authenticated requests.
• Access to your data is restricted to authorized personnel only.
• We do not sell, rent, or share your personal information with third parties for advertising, marketing, or data brokerage purposes.
• We do not use your data to build advertising profiles or for targeted advertising.

5. Your Privacy Rights

The app signs you in with an anonymous, device-scoped identifier and does not collect your name or email address. Because your data is not linked to your real-world identity, we are not able to look up, export, or selectively delete one person's data on request. You retain the following controls:

• Withdraw Consent: Stop using our services at any time.
• Revoke Permissions: Disable camera or photo library access at any time through your device's Settings app.

6. Data Retention

We retain your information for as long as needed to provide the service, including your scan history and stored lawn photos. Because the app uses an anonymous, device-scoped identifier, this data is not associated with your name or email. We may retain information where required for legal compliance.

7. Children's Privacy

Our app is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13. If we discover that a child under 13 has provided us with personal information, we will delete it immediately.

8. Camera and Photo Library Access

Our app requests access to your device camera and photo library for the following purposes:

• Capturing photos of your lawn for analysis.
• Selecting existing lawn photos from your library for analysis.

Photos are only uploaded when you choose to start a scan. Uploaded photos are stored securely in our cloud storage to support your scan history. You can deny camera or photo access and still use other app features.

9. Location Information

If you choose to share your region or ZIP code, we use it to tailor recommendations (climate, grass type compatibility, seasonal timing), including sending the approximate coordinates of your ZIP code to Open-Meteo to retrieve your local weather forecast. We do not collect precise device location.

10. Data Breach Notification

In the event of a data breach that compromises your personal information, we will notify affected users promptly in accordance with applicable laws. Because the app does not collect an email address, notice will be posted within the app and on our website, and will include the nature of the breach, the data affected, and steps we are taking in response.

11. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Effective Date" at the top. Continued use of the app after changes constitutes acceptance of the updated policy.

12. International Users

Your information may be transferred to and processed in countries other than your own. By using our app, you consent to the transfer of your information to the United States and other countries where our service providers operate.
