Privacy Policy for LineZ
Effective Date: February 24, 2026
I. Information We Collect: LineZ ("we," "our," or "us") collects the minimum amount of data necessary to calculate accurate wait times and venue capacity.
Location & Hardware Sensor Data: To verify venue presence and estimate crowd density, we collect your device’s precise geolocation (GPS), localized magnetic field data (magnetometer), altitude data (barometer), and environmental noise levels (microphone). Microphone data is processed locally to measure ambient decibel levels only; no audio is ever recorded, transmitted, or stored.
User-Generated Content (UGC): We collect photos, text, and manual wait-time reports that you actively submit to the platform.
Account Information: We collect basic authentication data to manage your account and points balance.
II. Dynamic Data Deletion Policy: To protect user privacy and ensure data relevance, LineZ operates on a strictly ephemeral database tied to individual venue operating hours.
Photos & Visual Content: All live photos and user-generated posts are permanently deleted from our active servers exactly at the closing time of the specific venue tagged in the post (e.g., if a venue closes at 3:00 AM, all daily content associated with that venue is wiped at 3:00 AM).
Wait Times: Live wait-time data is not stored historically. It is instantly overwritten the moment a new user submits an updated report for that specific venue.
We do not maintain historical location tracking logs of our users.
III. How We Use Your Information: We use your data exclusively to operate the LineZ app, calculate real-time venue wait times, verify user locations to prevent spam, and maintain the integrity of our leaderboard system. We do not sell your personal data to third-party data brokers.
IV. Third-Party Services: We utilize Supabase for user authentication and backend data storage, as well as mapping APIs to provide location context. These services operate under their respective privacy policies and are utilized strictly for the core functionality of the LineZ application.
V. Contact Us: For questions regarding this privacy policy or your data, contact us at: linezapplication@gmail.com.
