Privacy policy

Last updated: November 14, 2026

Prisma is a color-mixing game for iOS and Android. This policy explains what data it uses, why, and what you can do about it. In short: there are no accounts, your progress stays on your phone, and the only data that leaves it is what the purchase and the ads need.

Who is responsible

Fernando Medina, developer of Prisma. For any question about your data: fermedev1989@gmail.com.

What stays on your phone

Your progress (levels, Codex, streak, achievements, Sparks and cosmetics), your settings and the name you choose for the league are stored only on the phone. Prisma has no server of its own and sends them nowhere. Today the league is also worked out on the phone.

  • Notifications: they are local, to remind you of your streak. The phone itself schedules them and they go through no server. They are only requested once you complete the second day of a streak.
  • Motion: the Zen nebula reads the accelerometer to move the lights. That data is neither stored nor sent.
  • No analytics: Prisma uses no analytics or tracking tools of its own.

Purchases: RevenueCat

"Remove ads" is the only purchase. Apple or Google charge it with your store account; Prisma never sees your payment details. To validate the purchase, restore it on another phone and learn about a refund, the app uses RevenueCat, which receives an anonymous identifier it creates for each installation, the store's purchase receipts and technical details of the request (app version, operating system and store country). It does not receive your name or email.

Ads: Google AdMob

Prisma is supported by ads from Google AdMob. To show and measure them and to prevent fraud, Google receives device identifiers (on Android, the advertising ID), your IP address, device information, how you interact with ads, and diagnostic data. You can read how Google uses information from apps that use its services and adjust your preferences in My Ad Center.

  • On iOS the app does not ask for tracking permission (App Tracking Transparency), so it does not use Apple's advertising identifier (IDFA).
  • In the European Economic Area, the United Kingdom and Switzerland the app asks for your consent with Google's form before the first ad. If you do not give it, ads are not personalized. To choose again, clear the app's data or reinstall it and it asks again, or write to us.
  • "Remove ads" removes the mandatory ads. Rewarded ads stay available, but you only see them when you ask for them.

Legal bases

If you are in the European Union or the United Kingdom: the purchase is processed to perform our contract with you; personalized ads, with your consent; non-personalized ads, fraud prevention and site security, on the legitimate interest of supporting and protecting the game.

Children

Prisma is not directed at children and is not part of the stores' kids programs. If you believe a child has given us data, write to us and we will delete it.

How long data is kept

What is on the phone, until you erase it or uninstall the app. RevenueCat and the store keep purchase records for as long as they are needed to restore the purchase and for accounting obligations. Ad data, according to Google's policy.

Your rights

You can ask to access, correct or delete your data, object to or restrict its use, and complain to the data protection authority in your country. To erase what is on the phone, use Profile → Settings → Erase my progress or uninstall the app. Because there are no accounts, for what RevenueCat or Google hold, write to fermedev1989@gmail.com; we may ask for the store order number to find the purchase.

International transfers

Google, RevenueCat and Cloudflare process data in the United States and other countries, under the safeguards they offer (such as the European Union's standard contractual clauses).

This website

This website uses no cookies or analytics, and its fonts are served from the site itself. It is hosted by Cloudflare, which processes each visit's IP address to deliver and protect the pages.

Changes

If Prisma starts using data in a new way (for example, an online league), this page is updated beforehand and the date above changes.
