Your practice is yours.

Koe Na Win ("the app") is built so that your personal practice stays personal. This policy explains, plainly, what information the app stores, what it never collects, and the one optional feature — sign-in — that involves a third-party service.

Summary

• Your practice progress (attempts, days, rounds, and settings) is stored only on your device.
• Koe Na Win does not use analytics, advertising, or tracking SDKs of any kind.
• Signing in is entirely optional and never required to use the app.
• We do not sell or share your information with data brokers or advertisers.

Information stored on your device

Koe Na Win saves your practice record — start dates, attempts, days completed, round and bead counts, and your language and vibration preferences — in local storage on your phone. This information never leaves your device unless you choose to sign in (see below), and it is not visible to us. If you delete the app, this information is deleted with it.

Optional account sign-in

Settings offers an optional sign-in with Apple or Google, provided through Supabase, our authentication service. This is independent from your local practice progress, which is saved and works fully whether or not you sign in.

If you choose to sign in:

• Apple or Google shares basic identity information (such as your email address and a unique identifier) with our authentication provider, Supabase, to create your session.
• Your sign-in session is kept securely on your device using the operating system's secure credential storage, and is used only to recognize your account.
• We do not request or store your Apple or Google password.
• You can sign out at any time from Settings, which removes your session from the device.

Apple's and Google's own privacy policies govern the information they share when you choose to sign in with them.

What we don't do

• We don't include advertising or ad-tracking SDKs.
• We don't include behavioral analytics or usage-tracking SDKs.
• We don't access your contacts, photos, location, or microphone.
• We don't sell, rent, or trade your information.

Motion sensor access

If you choose Shake mode for counting, the app reads your device's motion sensor to detect a shake. This data is processed only on your device, in real time, to count a bead — it is never recorded or transmitted anywhere.

Children's privacy

Koe Na Win is not directed at children and does not knowingly collect information from children. The app's optional sign-in uses standard Apple and Google account flows, which apply their own age requirements.

Data deletion

Because your practice progress lives only on your device, deleting the app removes it completely. If you've signed in and would like your account deleted from our authentication provider, contact us at the address below and we will process your request promptly.

Changes to this policy

If this policy changes, we'll update the date at the top of this page. Continued use of the app after a change means you accept the updated policy.
