The fine print.

What ScreenBill is

ScreenBill shows you a daily "bill" for your phone usage, built from the usage data on your own device. The numbers are measured by Android and may differ slightly from other tools. The bill, the slabs, the roast and the certificates are for information and entertainment. They are not medical, psychological or financial advice, and the "charges" on a bill are not real money.

By installing or using the app you agree to these terms. If you do not agree, please do not use the app.

Using the app

• You need an Android device running Android 9 or newer, and you must grant usage access for the app to work.
• Don't reverse-engineer, resell or abuse the app or its servers, including the shared key the app uses to talk to our server.
• We may update, change or discontinue features. We will try to give notice of changes that matter, but we can't promise every version works forever.

Pro, skins and other purchases

ScreenBill Pro (subscription or lifetime) and bill skins are sold through Google Play and are subject to Google Play's terms. Prices are shown in Google Play before you buy. Subscriptions renew automatically until cancelled in your Google Play subscriptions; cancelling stops future renewals but does not refund the current period. Refunds are handled under Google Play's refund policy; if you have a problem with a purchase, contact us and we will help where we can.

Purchased items are tied to the Google account you bought them with. Reinstalling the app on a device signed into that account restores them.

Pre-registration reward

If you pre-register for ScreenBill on Google Play before its release, you receive the Japanese bill skin at no charge as a pre-registration reward. The reward is delivered through Google Play to the Google account that pre-registered, when you install the app after release, and it unlocks automatically in the app. It has no cash value, cannot be exchanged, transferred or refunded, and is limited to one per Google account. It does not include ScreenBill Pro or any other paid feature.

Your data

How the app handles data is described in the privacy policy. Your usage data stays on your device; you are responsible for anything you choose to share from the app, such as a bill image you send to others.

Warranty and liability

The app is provided "as is", without warranties of any kind. We do not guarantee that measurements are complete or exact, that notifications arrive at the exact minute, or that the app is free of errors. To the fullest extent permitted by law, Studio Mono is not liable for any indirect, incidental or consequential damages arising from use of the app, and our total liability for any claim is limited to the amount you paid for the app in the twelve months before the claim.

Changes and contact

We may update these terms; the current version is always on this page with the date above. Continued use after a change means you accept it. Questions go to studiomono.dev@gmail.com.
