Sereniton (styled SERENITŌN in the app) is published by Brownberg LLC. The plain spelling “Sereniton” is the product's legal and store name.

Last updated: August 28, 2026

The short version

The current Sereniton build has no accounts, login, analytics, advertising, in-app purchases, or application servers. The app does not request Internet access and does not transmit player data.

Progress and preferences live in one settings file on your own device. They are deleted when you uninstall the app.

What the app stores locally

• scenes unlocked and variant progress
• mechanic tutorials already shown
• headphones mode and gentle-vibration preference
• reduced-motion and first-run preferences
• inactive development fields reserved for a possible future subscription

The development subscription fields are not proof of a purchase and have no production entitlement authority. They are not transmitted.

Data collection and sharing

The current app does not collect or share personal data. It contains no live advertising, billing, analytics, account, upload, or cloud-storage SDK.

If advertising, billing, analytics, or another network service is added, this policy and the store Data Safety declaration will be updated from the final SDK-bearing binary before that version is released.

Permissions

• Vibrate: optional gentle haptic pulses during play. It can be turned off in the menu.
• Internet: not requested by the current Android build.

Use of AI

Sereniton's artwork and music are procedurally generated by software, and AI tools assisted development. No AI system runs inside the app and no player data is sent to an AI service.

Children

Sereniton is suitable for a general audience and is not directed primarily at children. The current build contains no advertising or behavioral tracking.

Your choices

• Turn headphones mode, vibration, or reduced motion on or off in the menu.
• Delete all locally stored game data by uninstalling the app.
