Privacy Policy for FogIndex

Last Updated: February 23, 2026

Introduction

FogIndex ("FogIndex," "we," "us," or "our") operates the FogIndex web application and related services. This Privacy Policy explains what information we collect, how we use it, when we share it, and your choices.

Scope

This Privacy Policy applies to information processed through FogIndex websites, applications, APIs, emails, and related services.

Information We Collect

1) Account and Identity Data

When you create or use an account, we may collect:

• Name/display name
• Email address
• Authentication provider and account identifiers (managed through Firebase Authentication)
• Account metadata such as creation time and verification status

2) Subscription and Billing Metadata

If you use paid features or trials, we may store:

• Plan name, subscription status, trial dates, forecast/location limits
• Stripe customer/subscription metadata (for example customer ID, price ID, billing interval)

Payment card details are processed directly by Stripe and are not stored by FogIndex.

3) Location and Forecast Configuration Data

To provide forecasts, we store:

• Saved location information (name, coordinates, timezone, terrain preferences)
• Alert thresholds and notification preferences
• Location-level settings (for example active/inactive and digest inclusion)

If you choose "Use Current Location," your browser may share precise location with us, subject to your device/browser permissions.

4) Notifications and Feedback Data

We collect and process:

• Notification preferences (for example alerts enabled, digest enabled, quiet hours)
• Email notification data needed to deliver alerts, digests, and feedback prompts
• Feedback responses submitted through one-click email links (including response type, click time, and optional user-agent string)
• If you use Field Check-In in the app, we may collect optional browser geolocation (with your permission) to rank nearby locations and record proximity metadata with your response

5) Technical and Usage Data

We may collect:

• Basic request/log metadata for security, reliability, debugging, and abuse prevention
• Rate-limit counters tied to your account for protected endpoints
• Product analytics events (for example sign-up/sign-in, location actions, page usage) via Google Analytics when enabled
• Essential cookies or browser storage used for session/authentication behavior and beta-access gating

Sources of Information

We collect information directly from you, automatically from your use of the Service, and from integrated providers.

How We Use Information

Data Security

We use reasonable technical and organizational safeguards designed to protect information. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.
