Privacy Policy

1. Introduction

SFBayWeather ("we," "us," or "our") provides a weather exploration tool for San Francisco Bay Area. This Privacy Policy explains how we collect, use, and protect information when you use our website.

2. Information We Collect

a. Location Data

If you grant permission, we access your device's geolocation to show weather near you. This data is processed in your browser and is not stored on our servers.

b. Analytics Data

We use Vercel Analytics to collect anonymous usage data including page views, referrers, browser type, and device type. This data does not include personal identifiers. See Vercel's Analytics Privacy Policy for details.

c. Error Reporting

We use Sentry to collect error reports when something goes wrong. These reports may include technical details such as browser version, operating system, and the URL where the error occurred. Sentry does not collect personal information. See Sentry's Privacy Policy for details.

d. Log Data

Our hosting provider (Vercel) may collect standard server logs including IP addresses, request timestamps, and URLs accessed. This is standard for all web services.

e. Feedback and Messages

When you use the contact form, send feedback, report a problem with a forecast, or rate an article, we store what you send in our own database, along with the page you sent it from. A forecast report also stores the weather values that page was showing. Your name and email address are optional. We use an email address only to ask about what you sent and, if you tick the box, to send you occasional email updates about new forecasts and features. Every update email includes a way to unsubscribe.

f. Browser Storage

The site keeps a random ID and your article ratings in your browser's local storage, so the same browser can't rate an article twice. The ID is not linked to your name or email, and it leaves your browser only when you send feedback or a rating. Clearing your browser's site data removes it.

3. How We Use Information

We use collected information to:

• Display weather data and comfort scores for destinations near you
• Understand aggregate usage patterns to improve the site
• Diagnose and fix technical issues
• Monitor site performance and availability
• Read messages and feedback you send us

4. Cookies and Tracking

We do not use advertising cookies or tracking pixels. Vercel Analytics uses a privacy-friendly approach that does not require cookies. Sentry may use minimal session data to group error reports. The random ID described in section 2f is kept in local storage, not in a cookie, and is never used for advertising.

5. Third-Party Services

We rely on the following third-party services:

• Vercel — Hosting and analytics
• Sentry — Error monitoring
• Neon — Database for messages and feedback you send
• Slack — Internal notifications when you send a message
• National Weather Service (NWS) — Weather forecast data
• Open-Meteo — Current weather and forecast data
• OpenStreetMap — Map tiles
• NOAA — Historical climate data, satellite imagery, and radar imagery

Each service has its own privacy policy. We do not sell or share your data with any third party for advertising purposes.

6. Data Retention

Analytics data is retained according to Vercel's standard retention policies. Error reports in Sentry are retained for 90 days. Messages, feedback and ratings you send are kept until we delete them or you ask us to. Submissions our filters mark as spam are deleted after 30 days. We do not maintain any user accounts.

7. Children's Privacy

Our service is not directed to children under 13. We do not knowingly collect information from children under 13.

8. Your Rights

Depending on your jurisdiction, you may have the right to access, correct, or delete personal data. The only personal data we hold is what you choose to send us, such as an email address in a message. To see it, correct it, delete it, or stop email updates, send a request through our contact form and include the email address you used.

9. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be reflected by updating the "Last updated" date at the top of this page.
