Privacy Policy
Effective 12 October 2026 · Last updated 12 October 2026
Spark Grid never asks who you are, and never tracks you.
- No account, no sign-up, no email address.
- No ads and no tracking across apps or websites.
- We use Firebase Analytics and Firebase Crashlytics to analyse and improve the game.
- Your progress stays on your iPhone.
- Game Center is optional and run by Apple.
Who we are
Spark Grid: Neon Circuits ("Spark Grid", "the game") is made by SparkGrid ("we", "us"). This policy explains what happens to your information when you play the game on iPhone.
Information we collect
We don't ask for your name, email, phone number, contacts, photos, or precise location, and the game has no account system. We never sell your information.
The only information that leaves your iPhone is the analytics and crash data described below, plus Game Center data if you choose to use it.
What stays on your device
To remember your game, Spark Grid saves the following only on your iPhone:
- Level progress, stars, best moves and best times
- Daily puzzle results and your streak
- Settings such as sound, haptics and colour-blind mode
- Which tutorials you have already seen
This data is never sent to us. You can erase it any time with Settings → Reset progress inside the game, or by deleting the app.
Analytics and crash reports
We use Firebase Analytics and Firebase Crashlytics, services provided by Google, to analyse how the game is used, fix crashes and improve the game. This data is not linked to your identity and is not used for advertising or tracking. Google processes it under the Google Privacy Policy.
Game Center
Spark Grid can show leaderboards and achievements through Apple's Game Center. Using Game Center is optional, and the game works fully without it.
If you sign in to Game Center, your scores and achievements are sent to Apple and may be visible to other players, depending on your Game Center settings. Apple handles this data under the Apple Privacy Policy. We don't receive your Apple Account email or your contacts. You can manage or turn off Game Center in iPhone Settings → Game Center.
Sharing your results
When you tap Share after a puzzle, the game creates a short text (for example your level, stars and time) and opens the standard iOS share sheet. You choose where it goes. We never see what you share or who you share it with.
Ads and tracking
Spark Grid contains no advertising and does not track you across other apps or websites. It does not use Apple's advertising identifier and never asks for tracking permission. Apart from Game Center, Firebase Analytics and Crashlytics, the game does not connect to the internet, and every puzzle works offline.
Children
Spark Grid is suitable for all ages. We do not knowingly collect personal information from children.
Your rights
Wherever you live, you may have rights over your personal data, such as accessing or deleting it. For any request or question, contact us at the address below.
Changes to this policy
If the game changes in a way that affects your privacy, we will update this page and the "Last updated" date before that version is released. If a future version ever collects any data, this policy will say exactly what and why before it does.

Common questions
How do I play?
Tap a tile to rotate it. Connect every bulb to a power source of the same colour. Red and blue power must never touch, except on a bridge. Open Settings → How to play to replay the tutorial.
A level looks impossible. Is it broken?
Every puzzle is built to be solvable. Try a hint, or reset the level. If you're sure something is wrong, email us the level number (or the Daily date) and we'll check it.
I reinstalled the game and my progress is gone.
Progress is saved only on your iPhone, so deleting the app also deletes your progress. Game Center scores and achievements stay in your Game Center account.
Game Center leaderboards don't show up.
Make sure you're signed in under iPhone Settings → Game Center, then reopen the game. You can also connect from the game's Settings screen.
How do I reset my progress?
Open the game's Settings and tap Reset progress. This can't be undone.
