Privacy Policy

What this project is

Fair Lawn Apps is a community project that pulls publicly available information from fairlawn.org and other public sources, then presents it in a more accessible format. It covers the Community Center gym schedule, library programs, Memorial Pool hours, local alerts, Farmers Market status, and theater events.

This is not an official Borough of Fair Lawn project. It is independently maintained by a Fair Lawn resident.

What gets collected

Push notification subscriptions

When you enable notifications for any app, your browser generates a push subscription endpoint (a URL). This is stored on Cloudflare Workers KV so notifications can be delivered to your device.

• The subscription endpoint is generated by your browser, not by Fair Lawn Apps
• No name, email, phone number, or other personal identifier is collected
• Your notification preferences (which alerts to receive, digest schedule, etc.) are stored alongside the subscription
• Subscriptions persist until you unsubscribe or your browser endpoint expires

Anonymous passkeys (cross-device sync)

If you choose to sync your notification preferences across devices, an anonymous passkey is created using WebAuthn. This is entirely optional.

• No username or email is required
• The passkey credential is stored in your device's secure enclave (never sent to the server)
• The server stores: an anonymous user ID, a session token, and a passkey credential ID
• An anonymous account password is generated automatically and is never shown to you
• This data is stored in a Cloudflare D1 database

Local storage on your device

Fair Lawn Apps stores some preferences directly on your device using your browser's localStorage. This data never leaves your device.

• Push subscription endpoint reference
• Notification preferences
• Calendar provider preference
• Alert watch list
• PWA install banner state
• No personally identifiable information is stored in localStorage

Analytics

Fair Lawn Apps uses Umami, a privacy-focused analytics tool.

• No cookies are used for analytics
• No personal data is collected
• Only page views and basic events are recorded
• No cross-site tracking
• Umami is GDPR and CCPA compliant by design

Feedback submissions

If you send feedback through the feedback page, your message, category, and a hash of your IP address are stored for up to 90 days. If you include your email, it is stored alongside your message for follow-up only — never shared or used for marketing.

Ephemeral data

Some features involve temporary data that expires automatically.

• Alert watches: If you "watch" an active alert (like a water advisory), that watch record expires after 30 days
• Session data: Login sessions for passkey sync expire per standard timeouts

What is NOT collected

• Names, email addresses, or phone numbers
• Location data
• Browsing history
• Cookies for tracking purposes
• Data from other apps on your device
• Data about children (this app is not directed at children)

Where data is stored

Server-side data is stored on Cloudflare infrastructure:

• Workers KV: Push subscriptions and alert watches
• D1 Database: Anonymous passkey accounts and sessions

No data is sold, shared with advertisers, or transferred to other third parties.

Data scraped from public sources

Fair Lawn Apps automatically reads publicly available information from fairlawn.org, the BCCLS library calendar, and similar public sources every 3 hours. No login credentials or private data is accessed. Only information that is already publicly visible on these websites is collected and reformatted.

Your rights

Under the New Jersey Data Privacy Act (effective January 15, 2025) and general best practice, you have the right to:

• Access what data is associated with your subscription
• Delete your data at any time
• Opt out of any data collection (data is never sold, so the "opt out of sale" right is satisfied by default)

To exercise any of these rights:

• To delete push subscriptions: Turn off notifications in any app, or visit Settings to manage all apps at once
• To delete passkey data: The anonymous account can be deleted through the Settings page
• To clear local data: Clear your browser's site data for fairlawn.paragbaxi.com
• For any other requests: Send us feedback

Children's privacy (COPPA)

Fair Lawn Apps is a general-purpose community information tool for Fair Lawn residents. It is not directed at children under 13. No personal information is knowingly collected from children. Push notifications deliver general community information (schedules, alerts) and are not personalized to any individual.

Changes to this policy

If this privacy policy changes, the updated version will be posted here with a new "last updated" date. Since no email addresses are collected, there is no way to send update notices. Checking back periodically is recommended.
