Privacy Policy
Last updated: 2026-10-30
This policy explains how the Reflex app (“Phản Xạ”, “the app”), operated by lucifer, handles information when you play on the web or as a Discord Activity.
1. Summary
Reflex does not require an account, does not collect your name, email or contact details, uses no analytics or advertising tools, and does not sell or share personal data with anyone.
2. Data stored on your device
To remember your progress, the app stores some data in your browser/device storage (localStorage or app storage). This data is not sent to our servers:
• Your game results (mode, difficulty, score, time played), experience points (XP) and level.
• Your chosen language.
• Your calibrated audio latency.
• Whether background music is on or off.
You can delete your results with the “Clear data” button on the Stats screen, or remove everything by clearing site data in your browser/Discord settings.
3. Playing inside Discord
When you open Reflex as a Discord Activity, the app only uses the Discord Embedded App SDK to tell Discord the game is ready. Reflex does not request access to your Discord account (no OAuth2) and does not receive your username, friends list, messages or server information.
Discord relays Reflex through its own systems. Discord’s handling of your data is governed by the Discord Privacy Policy (https://discord.com/privacy).
4. Infrastructure provider
The app is hosted on Cloudflare. As with any website, loading the app sends technical information (such as IP address, browser type and time of access) to Cloudflare’s servers. We do not use this information to identify you. Cloudflare processes it under its own policy (https://www.cloudflare.com/privacypolicy/).
5. Children
Reflex does not knowingly collect personal data from anyone, including children. When playing in Discord, you must meet the minimum age required by Discord’s Terms.
6. Changes to this policy
We may update this policy as the app changes, and will update the date at the top of this page. If a change significantly affects how data is handled, we will announce it in the app.
7. Contact
