# Privacy Policy

Last updated 11 November 2026

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. There is no Spark account to create. If you delete the app, this data is deleted with it.

## Purchases

Subscriptions and the lifetime purchase 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](https://www.revenuecat.com/privacy).

## 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 and there is no account, 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.

## Contact

Cyber Phoenix Ltd, United Kingdom. Email [support@sparkadhd.app](mailto:support@sparkadhd.app).

## Changes

If we change this policy we will update the date above. Material changes will also be noted in the app's release notes.
