How Cortex handles your data
Cortex is a brain-training game app. This page explains, plainly, what we collect, why, who can see it, and how to get it deleted.
1. Information we collect
We collect only what's needed to run the app. Specifically:
| Category | What, and when |
|---|---|
| Account basics | Email address and a display name. If you sign up with email/password, your password is stored as a salted hash by our authentication service โ we never see or store it in plain text. |
| Google Sign-In | If you choose "Continue with Google," we receive your Google account's email, name, and profile photo from Google to create or match your Cortex account. We don't receive your Google password, contacts, or anything outside that basic profile. |
| Profile photo | Either pulled from Google at first sign-in, or one you upload yourself from your device's photo library via Edit Profile. You can replace it at any time. |
| Gameplay data | Scores, accuracy, completion time, and category for every session you play, plus the streaks, XP, level, daily-challenge history, and Peak Brain Score / Brain Age figures we calculate from that history. |
| Social data | If you use Friends, we store friend requests/connections and friend challenge results. If you appear on a leaderboard, your rank is computed from your scores. |
| Device & diagnostics | Standard technical data your device sends any server it talks to (like IP address, at the network level) to keep the connection working. We do not run any analytics, advertising, or crash-reporting SDK inside the app, so nothing beyond that is collected. |
2. How we use it
- To create and secure your account, and let you log back in.
- To run the actual game mechanics: scoring, streaks, XP/leveling, daily challenges, and the Peak Brain Score / Brain Age calculations shown on your Progress screen.
- To power Leaderboard, Friends, and friend challenges.
- To send you local reminder notifications (e.g. streak reminders) โ these are scheduled on your own device, not delivered through a third-party push service.
- To respond when you email us for support or a data request.
We do not use your data to train third-party AI models, and we do not sell or rent it to advertisers or data brokers.
4. Third-party services we use
| Service | What it's for |
|---|---|
| Google Sign-In | Optional authentication method. When you use it, Google's own privacy policy governs the sign-in exchange itself. |
That's the only external service in the data path. No ad network, no analytics SDK, no third-party crash reporter is integrated into Cortex.
5. Where your data lives
Cortex runs on infrastructure we operate ourselves rather than a large third-party backend-as-a-service vendor. Your account and gameplay data are stored in a database we control, reached over an encrypted (HTTPS) connection. We don't hand your data off to a third party for storage or processing beyond the Google Sign-In exchange described above.
6. Retention & deletion
We keep your account and gameplay history for as long as your account is active, so your streaks, stats, and progress stay intact between sessions.
You can delete your account yourself, any time, from Profile โ Delete account in the app. Deleting is immediate and permanent โ it removes your profile, gameplay history, streaks, friends, and leaderboard entries, and can't be undone. If you'd rather not use the in-app flow, email admin@hubiez.com from the address on your account and we'll delete it for you.
7. Notifications
Reminder notifications (like streak reminders) are scheduled locally on your device โ we don't route them through a third-party push provider. You can turn them off at any time in your device's system notification settings for Cortex.
8. Children's privacy
Cortex is not directed at children under 13, and we don't knowingly collect personal information from anyone under 13. If you're a parent or guardian and believe your child has created an account or provided us information, contact admin@hubiez.com and we'll remove it.
9. Your choices
- Edit or replace your profile info โ name, username, and photo โ any time from Edit Profile.
- Sign out from Profile โ Sign out, which also clears any linked Google session on that device.
- Turn off notifications in your device's system settings.
- Delete your account yourself from Profile โ Delete account, or request a copy of your data by emailing admin@hubiez.com.
10. Security
Passwords are stored as salted hashes, not plain text. Traffic between the app and our servers is encrypted in transit. No method of storage or transmission is 100% secure, so while we work to protect your information, we can't guarantee absolute security.
11. Changes to this policy
If Cortex's features change in a way that changes what we collect or how we use it โ for example, adding real paid subscriptions or a new integration โ we'll update this page and change the effective date at the top.
