Privacy Policy · Tsumiki Launcher

CloudEx Inc. ("we", "us", or "our") operates the "Tsumiki Launcher" app (the "Service"). This Privacy Policy explains what information we collect, how we use it, and the choices available to you. By using the Service, you are deemed to have agreed to the practices described in this Policy.

1. Our Core Principle

Tsumiki Launcher is a home screen app (launcher) for Android. It lets you arrange apps, folders, and widgets on your home screen, find and open your apps from the app drawer and the search box, and assign actions to gestures. Your home screen, the app drawer, search, and gestures all run entirely on your device. There is no account and no sign-up, and the app contains no advertising SDK and no analytics SDK. We never collect, upload, or transmit to our servers any of the following:

The apps on your device, your home layout, or how often you open each app
The contents of your notifications
Your screen time
The contents of your screen or of other apps
What you type in the search box

The only information that leaves your device is the minimal information described in Section 3.1 (crash reports and communication with Google Play and our content server), and what you choose to send yourself — such as a web search you start from the search box, or a backup file you export.

2. Notification Access, Usage Access, and the Accessibility Service

Some features need special access that you grant in your device's system settings. Tsumiki Launcher asks for each one only when you turn on the feature that needs it; everything else works without them.

Notification access (notification dots): Used only to count how many notifications each app has, so that a dot (or, with Premium, the number) can be shown on the app's icon. The contents of your notifications are neither stored nor sent.
Usage access (screen time): Used only to show "today's screen time" on the Minimal home screen. The time is calculated on your device for this display only, and is neither stored nor sent.
Accessibility service (AccessibilityService API): Used only to carry out the gesture actions you choose — turning off the screen, opening recent apps, the power menu, taking a screenshot, and opening the notifications or quick settings. The service does not read the contents of your screen (it cannot retrieve window content and receives no accessibility events), and it does not collect any personal information. Before opening the system settings, the app explains this and asks for your consent. You can turn the service off at any time in your device's accessibility settings.
The list of your apps: To show the apps you can open on your home screen and in the app drawer, the app gets the list of apps that can be opened from a launcher. It does not use the permission to see all installed apps (QUERY_ALL_PACKAGES). This list is used only on your device.
Voice search: The microphone button in the search box opens your device's own voice input. Tsumiki Launcher does not use the microphone and never receives the audio.

3. Information We Collect

3.1 Information Collected Automatically

Crash reports: Via Firebase Crashlytics. When the app crashes, a report containing the stack trace, device model, OS version, app version, and an identifier for this installation of the app is sent to Google. Crash reports do not include information that identifies you personally.
Purchase information: To verify and restore your one-time "Premium" purchase, the app checks your purchases with Google Play. Payment is completed on Google Play, and we never receive any payment information such as credit card numbers.
In-app reviews and in-app updates: The app may show Google Play's rating dialog, or offer to install an update without leaving the app. Both are handled by Google Play.
List of our other apps: To show our other apps, the app downloads their names, descriptions, and icons from our content server (static files hosted on Cloudflare Pages). The request contains no personal data from the app. As with any request to a web server, the server receives your device's IP address as part of the connection. Tapping an app in the list opens its page on Google Play.

3.2 Information Stored Only on Your Device

The following is stored only in the app's storage on your device and is never sent to us.

Home layout: Where your apps, folders, and widgets are placed on each page and in the dock.
Settings and customizations: Appearance, app drawer, gesture, and Minimal settings, the names and icons you change for apps, and the apps you hide.
Launch counts: How many times you open each app, kept only to sort apps by how often you use them.
Daily copies of your layout: Before your home layout is changed for the first time each day, a copy of it is saved so that you can go back to it. Copies from the last 7 days are kept, and older ones are deleted automatically.
Backup files: When you export a backup, the file is saved only to the location you choose. Importing reads only the file you select.
Android backup: If backup is turned on in your device settings, Android may include your home layout and settings in the backup it saves to your own Google account, and may copy them to a new phone when you transfer your data. This is handled by Android; we have no access to it.
When you uninstall: Uninstalling the app or clearing its data deletes everything above from your device. Backup files you exported remain where you saved them until you delete them.

3.3 Information We Explicitly Do Not Collect

Your name, email address, phone number, or contacts (the app has no account or sign-up)
Your location
Your photos and videos, or anything captured by the camera or microphone
The contents of your notifications
The contents of your screen or of other apps
The list of apps on your device, how you use them, or your screen time
What you type in the search box, or the websites you visit

3.4 Permissions and Access the App Uses and Their Purposes

Tsumiki Launcher uses the following permissions and access only for the stated purposes. Notification access, usage access, and the accessibility service are requested only when you turn on the feature that needs them.

Notification access (notification listener) — Requested only when you turn on notification dots. Counts the notifications each app has. Their contents are neither stored nor sent.
Usage access (PACKAGE_USAGE_STATS) — Requested only when you show today's screen time on the Minimal home screen. The result is neither stored nor sent.
Accessibility service (AccessibilityService API) — Requested only when you use a gesture to turn off the screen, open recent apps, the power menu, take a screenshot, or open the notifications or quick settings. It does not read the contents of your screen and does not collect personal information.
Visibility of other apps (package queries) — Used to show the apps you can open from the home screen, and to find the widgets and icon packs you can choose. The app does not use QUERY_ALL_PACKAGES.
Request to uninstall apps (REQUEST_DELETE_PACKAGES) — Used only when you choose "Uninstall" for an app. Android asks you to confirm before anything is removed.
Expand the status bar (EXPAND_STATUS_BAR) — Lets a swipe gesture pull down the notifications or quick settings. It does not read your notifications.
Internet (INTERNET) — Used only for crash reports, Google Play purchase verification, in-app reviews and in-app updates, downloading the list of our other apps, and showing this privacy policy in the app. The home screen and the app drawer do not require an internet connection.

4. How We Use Information

The limited information we collect is used only for the following purposes:

Operating and maintaining the Service
Verifying and restoring your Premium purchase
Diagnosing and fixing crashes
Responding to support inquiries
Complying with applicable laws

5. Third-Party Services

Tsumiki Launcher uses the following third-party services. Each service has its own privacy policy.

Firebase Crashlytics (Google LLC) — crash diagnostic data
Google Play Billing (Google LLC) — the one-time Premium purchase; payment is completed on Google Play, and we never receive your payment information
Google Play In-App Review and In-App Updates (Google LLC) — let you rate the app and install updates without leaving it; handled by Google Play
Cloudflare Pages (Cloudflare, Inc.) — hosts the static list of our other apps

When you choose to search the web or the Play Store from the search box, the app passes the words you typed to your device's search app (or to Google Search in your browser if there is none) or to the Google Play Store app. The search is then handled by that service under its own privacy policy, and we do not receive it.

Tsumiki Launcher contains no advertising SDK and does not share your data with advertising networks.

6. Data Retention

Crash reports: retained for 90 days, then deleted.
Support emails: retained for 12 months after the last reply, then deleted (except where legally required).
Your home layout, settings, and launch counts on your device: kept until you change or delete them, uninstall the app, or clear the app's data. Daily copies of your layout are kept for 7 days and then deleted automatically.

7. International Data Transfers

We are based in Japan. The infrastructure used for crash diagnostics and for hosting the list of our other apps may be located in various countries. When you use the Service, the minimal information described above may be processed outside your country of residence under standard contractual safeguards.

8. Your Rights

Depending on where you reside (e.g., the EEA, UK, California, Japan), you may have the right to request access to, correction of, or deletion of the limited information we hold. You can:

Turn off notification dots, screen time, or gesture actions in the app at any time, and withdraw notification access, usage access, or the accessibility service in your device settings at any time
Uninstall the app or clear its data to erase the home layout, settings, and launch counts stored on your device
Contact us at the address below to make a request regarding the information we hold

9. Children's Privacy

Tsumiki Launcher is not directed to children under the age of 13 (or the minimum age applicable in your region). If we inadvertently collect information from such a child, we will delete it promptly upon being contacted.

10. Changes to This Policy

This Privacy Policy may be updated from time to time. The latest version is always published at this URL together with its effective date. We will also notify you within the app of significant changes as appropriate.
