Privacy Policy

Last updated: March 21, 2026

1. Introduction

BigRENDER LLC ("we", "us", or "our") operates the Locus Guide mobile application and website (collectively, the "Service"). This Privacy Policy explains how we collect, use, disclose, and safeguard your personal data when you use our Service.

By using Locus Guide, you agree to the collection and use of information in accordance with this policy. If you do not agree, please do not use the Service.

2. Data We Collect

2.1 Account Data

When you create an account, we collect:

  • Email address (via Firebase Authentication)
  • Display name (if provided)
  • A pseudonymous user identifier (we do not use your email as a primary key)

2.2 Usage Data

We automatically collect limited technical data to ensure the Service functions correctly:

  • Device type and operating system version
  • App version
  • Tour progress and completion status
  • Language preferences

2.3 Location Data

Locus Guide uses your device's GPS to provide audio tours that play automatically as you walk. Location data is processed locally on your device to trigger audio playback and is not transmitted to our servers or stored remotely. You can revoke location permissions at any time through your device settings.

2.4 Data We Do Not Collect

We do not collect or store:

  • Precise location history on our servers
  • Contacts, photos, or other personal files
  • Financial or payment information (purchases are handled entirely by Apple App Store or Google Play)
  • Advertising identifiers

3. How We Use Your Data

We use the data we collect for the following purposes:

  • To provide and maintain the Service (account management, tour delivery)
  • To save your tour progress so you can resume where you left off
  • To deliver content in your preferred language
  • To improve the Service (aggregated, non-identifying usage statistics)
  • To communicate important service updates

4. Cookies and Local Storage

Our website uses only essential cookies required for authentication and session management. We do not use advertising, analytics, or tracking cookies.

The mobile application uses local device storage to cache tour content for offline use. This data remains on your device and is not shared.

5. Third-Party Services

We use the following third-party services:

5.1 Firebase Authentication (Google)

We use Firebase Authentication to manage user sign-in. Firebase may collect device identifiers and IP addresses as described in Firebase's Privacy Policy.

5.2 OpenStreetMap

Map tiles displayed in the app and on our website are provided by OpenStreetMap contributors. When maps load, your device connects to tile servers, which may log IP addresses. See the OpenStreetMap Privacy Policy for details.

5.3 Apple App Store / Google Play

If you download the app or make purchases, those transactions are governed by the respective store's privacy policies. We do not receive or store your payment information.

6. Data Sharing and Disclosure

We do not sell, rent, or trade your personal data. We may share data only in these limited circumstances:

  • Service providers: Third-party services listed in Section 5, solely to operate the Service
  • Legal requirements: When required by applicable law, regulation, or legal process
  • Safety: To protect the rights, safety, or property of BigRENDER LLC, our users, or the public

7. Data Retention

We retain your account data for as long as your account is active. Usage data is retained in aggregated, non-identifying form. If you delete your account, your personal data is permanently removed within 30 days, except where retention is required by law.

8. Data Security

We implement industry-standard security measures to protect your data, including encrypted connections (TLS/SSL), secure server infrastructure, and access controls. However, no method of transmission over the Internet is 100% secure, and we cannot guarantee absolute security.
