Privacy policy
Last updated: October 27, 2026
1. About this policy
AUX ("we," "our," or "us") is a free stock market game for music in the AUX app for iPhone, available on the App Store. It is scored in percentages only and involves no money. This policy explains what information the AUX app and the AUX game service collect, how we use it, who we share it with, and how you can delete it.
2. The short version
- We collect what we need to run your account and the game.
- AUX has no ads and no third-party analytics or advertising SDKs. We do not track you across other companies' apps or websites, and we do not sell your personal information or share it for advertising.
- You can delete your account and game data at any time in the app: Portfolio → your profile → Settings → Delete account.
3. Information we collect
Account information
- Email address: used to sign you in (with one-time codes sent by email) and to contact you about your account. If you sign in with Apple and choose "Hide My Email," we receive an Apple relay address instead of your real one.
- Name (optional): if you sign in with Apple or Google, that provider may share your name with us, and we store it with your account.
- Username: the public name shown to other players on the leaderboards, in leagues and on your profile.
- Identifiers: the user ID we assign to your account and the account ID of the sign-in provider you use (Apple or Google).
Gameplay data
The albums in your portfolio and the swaps you queue, with their times; your portfolio's daily percentage moves and your leaderboard and league ranks after each daily update; the leagues you create or join, with the names you give them; the daily updates you have seen; the reports you send; and the players you have blocked.
Push notification tokens
If you allow notifications, we store your device's push token and platform so we can send game notifications, such as your portfolio's daily move. You can turn notifications off at any time in your device settings or in the app's Settings.
Usage events
The app sends us first-party events about how you use AUX (for example, opening the app, viewing an album or swapping one into your portfolio), with a timestamp and your account ID. We collect these ourselves to run and improve the game. They are not sent to any third-party analytics or advertising service.
Technical data
Like any online service, our servers and hosting providers receive technical request data such as your IP address, device and operating-system type, and request times. We keep it in logs for security and troubleshooting.
What we don't collect
We do not collect your precise location, contacts, photos, health or financial information, or payment details (AUX has no purchases and no money of any kind). We do not use your device's advertising identifier, and the app does not use your camera or microphone.
4. How we use information
- To create and secure your account and sign you in
- To run the game: your portfolio, swaps, album prices, daily updates, leaderboards and leagues
- To send the notifications you have allowed
- To prevent cheating, abuse and fraud (for example, playing one league with several accounts)
- To understand how the game is played and improve it, using our first-party usage events
- To respond to your support requests
- To comply with the law and enforce our Terms
5. What other players can see
Other players see your username, your ranks and your gains as percentages on the leaderboards and in leagues you share with them. Your profile shows them your albums with each one's move since you added it, when you started playing, and your public leagues (private ones only to players in them too). Album prices move only with streaming data, never with what players pick. A share image shows only what you choose to post: your username, your albums' covers and their percentage moves. If you block a player, or they block you, you are shown to each other without a name. Your email address and any name from your sign-in provider are never shown to other players.
6. Who we share information with
We share information only with service providers that process it on our behalf to run AUX, and only as needed for that:
- Supabase: authentication and the game database
- Our cloud hosting providers: run the servers that operate the game
- Our email delivery provider: sends your sign-in codes
- Apple and Google: when you choose to sign in with them. Push notifications are delivered through Expo's push notification service and Apple's push service.
- Music catalog services: to show cover art and play short song previews, the app loads images and audio from third-party music services. These requests contain no account information, but like any web request they reveal your device's IP address to that service.
We may also disclose information if the law requires it, to protect the rights, safety or security of our users or the service, or as part of a merger, acquisition or sale of assets.
We do not sell your personal information, we do not share it for cross-context behavioral advertising, and we do not use it to track you across other companies' apps or websites.
7. Where your data is stored
Your data is stored with Supabase and on the infrastructure that runs the game, which may be located in the United States or other countries whose data-protection laws differ from yours. Where the law requires it, we use appropriate safeguards for these transfers.
8. Keeping and deleting your data
We keep your account and game data for as long as your account exists.
Delete your account in the app: go to Portfolio → your profile → Settings → Delete account. This permanently erases your account and its game data: your profile, your portfolio and its history, swaps, league memberships and results, blocks and push tokens. Deletion takes effect immediately in our live systems. Copies that remain in encrypted backups and logs are removed as those roll over, typically within 30 days. You can also ask us to delete your account by emailing support@playaux.com.
We may keep aggregated or de-identified information that can no longer be linked to you, and information we are legally required to keep.
9. Your rights and choices
- Correct: email us to change your username
- Delete: delete your account in the app at any time (see above)
- Notifications: turn them off in the app's Settings or in your device settings
- Access, correction, portability and objection: depending on where you live (for example, under the GDPR, UK GDPR or California law), you may have these and other rights. Email support@playaux.com and we will respond as the law requires. We will not discriminate against you for exercising them.
10. Children
AUX is intended for adults and is not directed to children. You must be at least 18 years old (or the age of majority where you live) to use it. If you believe a child has given us personal information, contact support@playaux.com and we will delete it.
11. Security
We encrypt data in transit, use access controls, and rely on providers with strong security practices. No system is perfectly secure, so we cannot guarantee absolute security.
12. Changes to this policy
If we change this policy, we will update the "Last updated" date above, and for material changes we will let you know in the app or by email before they take effect.
