Privacy Policy

Last updated 7 September 2026

This policy is for the Android app ONE (com.zenkaiapps.one). ONE is a sit timer. You dump a thought, sit with it, and park the rest for later.

What we store

ONE keeps your dumps, parked thoughts, sit timer, and noise preference on this device only. There is no account and no server of ours. We do not see your thoughts.

• Thought text you type
• The later list
• The active sit (length, remaining time, paused or playing)
• Whether brown noise is on

Android may also include that local data in your Google backup if device backup is on. Uninstalling ONE or clearing the app’s storage in Android settings wipes it.

What we do not collect

We do not ask for your name, email, or location. We do not run our own analytics. We do not sell your data. We do not send your thoughts to anyone.

Advertising

ONE is meant to be supported by ads. When ads are on, they are served by Google AdMob. Google may use an advertising ID, IP address, and device information to show ads. That is Google’s processing, not ours. Your thoughts are not sent to AdMob.

Google’s policy: policies.google.com/privacy

Notifications and audio

During a sit, ONE can show a lock-screen player and keep brown noise playing. That uses notification and foreground-service permissions. Those controls are for the timer. They are not used to track you.

Children

ONE is not directed at children under 13.

Your choices

• Clear parked thoughts inside the app
• Clear ONE’s storage in Android settings
• Uninstall the app
• Limit ad personalization in your Google account / Ads settings

Changes

If this policy changes, we will update this page and the date above. The same summary also lives on the Privacy screen inside ONE.
