Numina Privacy Policy
Numina is made by ByteXio LLC. This policy describes what Numina does with information, and it is deliberately short because the app is designed to need very little of it.
The short version
- Numina has no accounts. There is nothing to sign up for.
- Numina has no servers of ours. The app never sends your play data, your answers, or anything about you to ByteXio.
- Numina contains no analytics, advertising, or tracking SDKs, and does not use Apple's advertising identifier or ask for tracking permission.
- Everything you do in Numina — your progress, streaks, ratings, session history, and Deep Sky conversations — is stored on your device.
What is stored on your device
Your player profile: constellation ratings, resonance, streaks, session history, daily play summaries, Deep Sky transcripts you choose to keep as Moments, and your settings. This lives in the app's private storage on your iPhone, iPad, or Apple Watch. Deleting the app deletes it.
Optional iCloud sync
If you turn on Settings → iCloud sync, your profile is stored in the iCloud key-value store attached to your own Apple ID, so it follows you between your iPhone and iPad. This goes to Apple's iCloud, under your account, protected by Apple's iCloud security. ByteXio has no access to it. It is off by default, and turning it off stops further sync.
Apple Watch
Play on Apple Watch is exchanged with the paired iPhone using Apple's WatchConnectivity, directly between your two devices. It does not pass through any server of ours.
Deep Sky and on-device intelligence
Deep Sky conversations run entirely on your device:
- Apple Intelligence, where available, runs on device using Apple's Foundation Models framework.
- The built-in Starlight guide is used on every other device. It needs no download and no network at all.
Puzzle content, answers, and scoring are always decided by Numina's own engine on your device — never by a model.
Duels
Nearby duels connect two devices directly, over your local network or Apple's device-to-device wireless link. When you open Duel, Numina asks iOS for Local Network permission so it can find players near you. The only things shared are the display name you choose, your level, and the moves of the race (answers, timing, and score). They go only to the player you are duelling, never to ByteXio, and are not stored by anyone but the two devices. Head-to-head records are kept on your device.
Online duels use Apple's Game Center to find an opponent or invite a friend, and to carry the race between the two devices. Online, other players see your Game Center name (not your nearby Duel name), and the only messages that can be exchanged are the race itself and a fixed set of reaction emoji. That traffic is handled by Apple under Apple's Game Center terms; ByteXio does not receive it.
Game Center
If you turn on Game Center, Numina reports your Today's Math score, lifetime resonance, and best streak to Apple's Game Center leaderboards. This is handled by Apple under Apple's Game Center terms. It is off by default.
Notifications
Streak, Deep Signal, and comeback reminders are local notifications scheduled on your device. No push service is involved and nothing is sent anywhere to deliver them.
Purchases
Numina Pro is sold by Apple through the App Store, as an annual or monthly subscription or a one-time Lifetime purchase. Apple handles payment, trials, renewals and refunds; ByteXio never sees your payment details or your Apple Account. The app asks the App Store on your device which plan you own, and nothing about it is sent to us. Purchases are tied to your Apple Account and can be restored from Settings → Restore purchases.
Children
Numina does not knowingly collect personal information from anyone, including children, because it does not collect personal information.
Changes
If this policy changes, the new version will be published at the same address and the effective date above will be updated.
