Facet Duels
Privacy Policy
Effective 11 November 2026
The short version
Facet Duels has no ads and no analytics. Playing against the AI or on one phone sends nothing to us. Playing online sends your moves and a random id the app makes to our match server, which keeps them while the match lasts and then deletes them. Signing in is optional; if you do, we keep your account's id and your matches until you delete the account. Our server never receives your name or email.
Who we are
Facet Duels is published by burgundygames, a brand of DigitalBurgundy, a sole proprietorship registered in the Philippines and owned by Alvin Joseph Arzadon. DigitalBurgundy is responsible for the personal data described in this policy. You can reach us any time at support@burgundysoft.io. This policy covers the Facet Duels app on iOS and Android. Facet, our single-player game, has its own policy.
Playing on your phone
Matches against the AI, pass-and-play and the Daily Duel run entirely on your device. Your progress, cards and settings are stored there and are not sent to us. Deleting the app deletes them.
Playing online
Online matches are played through a match server we run. The first time you play online, the app makes a random id (22 characters, not derived from anything about you or your device) and keeps it on your phone. For each match, our server receives and keeps that id, the cards you chose, your moves, and a token that lets your phone rejoin if the connection drops.
A live match is deleted from the server 10 minutes after it ends, or when it's abandoned. A match played on your own time is deleted 24 hours after it was opened if nobody joined, and otherwise 7 days after it ends, so you can see the result. The server also counts, minute by minute, how many people are playing, so we know when to open a public queue; those counts contain no ids, rooms or connections.
The server doesn't log connections or keep your IP address. Connections reach it through Cloudflare, which passes them on without giving our host your address.
Notifications
If you allow notifications, the app gives our server a push id (a Firebase installation id) for each match you play on your own time. It's kept with that match, and used only to tell you it's your turn, that your turn is about to run out, or how the match ended. Google's Firebase Cloud Messaging delivers them, through Apple's push service on iOS. Turning match notifications off in the app's settings takes the push id back from every match.
The Duel Hour reminder is scheduled on your phone; nothing is sent to us for it.
Accounts (optional)
You can sign in with Apple, or with Google, so your online matches follow you to a new phone. You never need to: everything in the app works without it.
Sign-in is handled by Google's Firebase Authentication. Our server receives proof of who signed in and keeps three things: your account's id (a random string Firebase assigns), the random player id it plays as, and the matches you're playing on your own time. It never receives your name or email.
Firebase keeps the sign-in account itself. If you sign in with Google, that includes the email address, name and profile photo your Google account shares; with Apple, we ask Apple for neither your name nor your email. Google may also log the IP address of a sign-in to protect against abuse, under its own policy.
We keep the account until you delete it. Signing out keeps it, so you can sign in again later.
Deleting your account
In the app, open Settings → Account → Delete account. That deletes the account from our server and from Firebase straight away. If you no longer have the app, ask us to delete it.
Matches still in progress carry on until they end and are then deleted as above; they hold your random player id, not your account.
Who else handles data
These companies handle data on our behalf, or directly when you use the parts of the game they power:
| Service | Receives | Used for |
|---|---|---|
| Railway | Everything our match server keeps, described above | Hosting the match server |
| Cloudflare | Your connection to the match server, including your IP address while it's open | Passing the connection on; it isn't stored for us |
| Google Firebase | Push ids and the text of each notification; your sign-in account if you have one; device model, language, OS and app version from the Firebase SDK | Delivering notifications and signing in |
| Apple Game Center / Google Play Games | Your player ID and the scores you submit | Leaderboards, only if you are signed in |
We don't sell data, share it with advertisers, or use it to track you across other apps.
Children
Facet Duels is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has signed in, contact us at support@burgundysoft.io and we will delete the account.
Your choices
You can play without going online, play online without signing in, turn match notifications off, sign out of Game Center or Play Games, or delete your account. Uninstalling the app removes everything stored on your phone; matches already on our server are deleted on the schedule above.
Changes to this policy
If the app starts collecting something new, this page changes before that version ships, and the effective date at the top changes with it.
