Privacy Policy

Last updated: May 15, 2026

LyneGuide ("we", "us") is a nightlife app that surfaces real-time and predicted line waits at bars, clubs, and restaurants. This page explains what data we collect, why we collect it, and how to remove it.

What we collect

• Account. Email address (Firebase Authentication) and an optional unique display name you choose.
• Location. Approximate location when the app is open (sorts nearby venues, distance), and optional background geofence crossings (prompts you to report a wait when you arrive). Location stays on your device until you submit a queue report; once you submit, the coordinates of that submission are stored alongside it so we can validate proximity.
• Queue reports + venue affinity. Each time you tell the app you are in a line we store the venue id, the timestamp, a coarse location snapshot, and a per-venue affinity score derived from dwell time and explicit thumbs-up / thumbs-down votes.
• User-generated content. Vibe reactions (emoji) you tap on a venue and venues you suggest adding. Vibe reactions are anonymized in the public aggregate.
• Diagnostics. When the app crashes, Firebase Crashlytics records a stack trace, the device model, OS version, and a hashed user id. We use this only to fix bugs.

What we do not collect

• We do not sell your data to third parties.
• We do not store the contents of your phone's address book or your location history outside of queue reports you submit.
• We do not show third-party advertising banners. The only third-party commercial relationships are optional rideshare buttons (Uber, Lyft) that, if approved, may include an affiliate code so LyneGuide earns a small commission. Tapping a rideshare button hands you off to that app and we do not share your account info with the rideshare partner.

Who sees your data

• You. Everything you create is readable by you.
• Other LyneGuide users. Aggregated, anonymized vibe and wait data shows up on venue pages. Individual report content does not.
• LyneGuide operators. Engineers on the team access production data only to diagnose crashes, respond to support email, or review moderation reports.

How long we keep data

Queue reports are kept for analytics. Crash diagnostics are retained for up to 90 days.

How to delete your data

Open the LyneGuide app → Profile → Danger Zone → Delete My Account. This permanently removes your account, favorites, reports, and display-name claim, then deletes your Firebase Auth record. If you cannot access the app, email matthewkpapas2@gmail.com from the address tied to your account and we will delete it within 30 days.

Children

LyneGuide is not intended for users under 17. We do not knowingly collect data from anyone under 17. If you believe a minor has registered, email us and we will remove the account.

Changes to this policy

If we make material changes, we will update the "Last updated" date at the top of this page. We will also surface a short in-app notice when the change affects what we collect.
