Spark Privacy Policy
Spark is made by Cyber Phoenix Ltd ("we", "us"). This policy explains what happens to your information when you use the Spark app and this website. The short version: your training data stays on your phone.
What stays on your device
Your goals, placement results, skill scores, game history, streaks, reminder times and anything you write in Park It are stored only on your phone. We do not receive them unless you choose to back them up (see below). You never need an account to play. If you delete the app, this data is deleted from the phone with it.
Optional account and backup
You can sign in with Apple, Google or an email code to back up your progress and restore it on a new phone. If you do, we store your email address, your name if your sign-in provider shares it, which sign-in method you used, and your backed-up progress (skill scores, game history, streaks and settings). We use it only to provide the backup and to link your Spark Plus purchase to you. You can delete your account and its data in the app at any time.
Purchases
Subscriptions are handled by Apple through the App Store. We use RevenueCat, a subscription service, to check whether you have Spark Plus. RevenueCat receives an anonymous app user ID, your purchase receipts and basic device information (such as country, app version and operating system). It does not receive your name, email address or payment card details, and it does not receive your training data. See RevenueCat's privacy policy.
Notifications
If you turn on reminders, they are scheduled on your phone. We do not run a notification server and do not see when you play.
No ads, no tracking
Spark shows no ads, contains no advertising SDKs and does not track you across other apps or websites. We do not sell or share personal data.
This website
sparkadhd.app is hosted by Cloudflare, which processes standard request data (such as IP address and browser type) to deliver and protect the site. We do not use advertising cookies on this site.
Children
Spark is built mainly for adults. Anyone can use it, and because training data stays on the device unless an adult chooses to sign in, we do not knowingly collect personal information from children. A parent or guardian should set up any purchase for a child.
Your rights
Under UK GDPR and similar laws you can ask what personal data we hold about you and ask us to delete it. Because we hold almost none, most requests are answered by deleting the app. For purchase records, Apple and RevenueCat hold them; email us and we will help.
