CloudEx Inc. ("we", "us", or "our") operates the "Edge Lighting Pro" 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
Edge Lighting Pro lets you know about notifications and incoming calls by lighting up the edges of your screen. While you are using your phone, the light is drawn over other apps; when the screen is off or locked, the app turns the screen on and lights up the edges of a black screen. Deciding whether to light up and drawing the light both happen entirely on your device. The app does not read the contents of your notifications — their text, title, or sender — and nothing about your notifications or calls is sent to us. There is no account and no sign-up. Specifically, we do not have access to any of the following:
- The contents of your notifications (text, title, sender, images, and the like)
- Your phone numbers, call history, or contacts
- Which apps notified you and when (the light history stays on your device)
- The apps installed on your device, or the apps and colors you choose in the app
2. Notifications, Calls, and the Light
- Notification access: To know when to light up, the app uses Android's notification access (a notification listener). From each new notification it looks only at: that a notification arrived (and, later, that it was removed), which app it came from (the app's package name), whether it makes a sound (its importance, and whether Do Not Disturb lets it through), what kind of notification it is (ongoing notifications, group summaries, media playback, and the like are ignored), and whether it is an incoming call (the notification's category and call type). It does not read the text, title, or sender of any notification. None of this leaves your device.
- Incoming calls: Calls are detected from your calling app's incoming-call notification. If you also allow the optional phone permission, the app checks only whether the phone is ringing (the call state), so that the call light and flash start reliably. It does not read phone numbers, your call history, or your contacts.
- The camera light: Flash on call and flash on notifications (Premium) blink your phone's flashlight. The app switches the flashlight on and off without opening the camera: it does not use the camera permission and never takes photos or videos.
- Proximity sensor: Before turning on a screen that is off, the app briefly checks the proximity sensor to tell whether your phone is in a pocket or a bag. The reading is used only for that decision and is not saved.
- Device state: To decide whether to light up, the app checks on the spot whether the screen is on or locked, the battery level and whether it is charging, the ringer mode, whether a call or an alarm is in progress, and the time (for quiet hours). These are not saved or sent.
- Your list of apps: Screens such as "Apps that light up" show the names and icons of the apps on your device that appear in your launcher, so that you can choose them. The list is shown only on your device and is never sent anywhere.
3. Information We Collect
3.1 Information Collected Automatically
- Crash reports: Via Firebase Crashlytics. When the app crashes, a crash report is sent containing the stack trace, device model, OS version, app version, and a Firebase installation ID (a random identifier for this installation of the app). It does not include the contents of your notifications, your light history, or your settings. The app does not use Firebase Analytics or any other usage analytics.
- Purchase information: To unlock and restore the one-time "Premium" purchase, the app asks Google Play whether your Google account has bought it. We never receive any payment information such as credit card numbers.
- List of our other apps: To show our other apps, the app downloads their names, descriptions, and images 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 You Send Us
- Support emails: If you choose "Contact us" in the app, your mail app opens with the app's name in the subject and your device model, Android version, and app version in the body, to help us look into your question. You can see and edit all of it before sending, and nothing is sent unless you send the email yourself. We receive your email address and whatever you write.
3.3 Information Stored Only on Your Device
- Light history: For each notification the app looked at, the time, the app's package name, and whether it lit up (or the reason it did not) are kept on your device, newest first, up to 200 entries; older entries are removed automatically. It is there to help you find out why something did not light up, and you can erase it at any time with "Clear history". It is excluded from Android backups and from device-to-device transfers.
- App settings: How the light looks, the apps you choose, per-app colors (an app's package name and its color), the conditions that keep the light off, and whether you have bought Premium are stored on your device.
- Android backup: If backup is turned on in your device settings, Android may include the app's settings in the backup it saves to your own Google account (Google Drive), and may copy them to a new phone when you transfer your data directly. The light history is always excluded. This is handled by Android under your Google account's backup settings; we have no access to it.
- When you uninstall: Uninstalling the app or clearing its data deletes the light history and the settings stored on your device.
3.4 Information We Explicitly Do Not Collect
- The contents of your notifications (text, title, sender, images, and the like)
- Phone numbers, call history, or contacts
- Your location
- Photos, videos, sound, or anything from the camera or microphone
- Your name, email address, or phone number (the app has no account or sign-up), except what you include when you email us
- A history of the websites you visit, or the contents of your screen or of other apps
3.5 Permissions the App Requests and Their Purposes
Edge Lighting Pro uses the following permissions and special access only for the stated purposes. It does not use an accessibility service, and it does not request the location, microphone, camera, contacts, or storage permissions.
- Notification access (notification listener) — The core function: knowing that a notification or an incoming call has arrived, as described in Section 2. You grant it in the system settings and can turn it off there at any time; while it is off, the app does not light up for notifications.
- Display over other apps (SYSTEM_ALERT_WINDOW) — Draws the light on the edges of the screen over other apps, and lets the app show the light on the lock screen. The light lets touches pass through, so it never gets in the way of what you are doing. It does not read any screen content.
- Phone (READ_PHONE_STATE, optional) — Checks only whether the phone is ringing, so that the call light and flash start reliably. It is requested only on the Calls tab (for example, when you turn on Flash on call), and the app works without it. Phone numbers, call history, and contacts are not read.
- Prevent phone from sleeping (WAKE_LOCK) — Keeps the phone awake while the flashlight blinks and while you test the light with the screen off, so that they finish properly.
- Run at startup (RECEIVE_BOOT_COMPLETED) — After your phone restarts or the app is updated, asks Android to reconnect the notification listener so that the light keeps working.
- Google Play billing (com.android.vending.BILLING) — Buying and restoring Premium through Google Play.
- Internet and network state (INTERNET / ACCESS_NETWORK_STATE) — Used only for crash reports, Google Play purchases, in-app reviews and in-app updates, downloading the list of our other apps, and showing this privacy policy in the app. The edge light itself does not need an internet connection, and the contents of your notifications are never sent.
4. How We Use Information
The limited information we collect is used only for the following purposes:
- Operating and maintaining the Service
- Unlocking and restoring your Premium purchase
- Diagnosing and fixing crashes
- Responding to support inquiries
- Complying with applicable laws
5. Third-Party Services
Edge Lighting Pro uses the following third-party services. Each service has its own privacy policy.
- Firebase Crashlytics (Google LLC) — crash reports
- Google Play Billing (Google LLC) — buying and restoring the one-time Premium purchase; payment is completed on Google Play, and we never receive your payment details
- 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
Edge Lighting Pro does not sell your data and does not share it 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).
- The light history on your device: the latest 200 entries are kept, and older ones are removed automatically. You can clear it at any time, and it is deleted when you uninstall the app or clear its data.
- The settings on your device: kept until you uninstall the app or clear its data. Any copy in your Android backup follows your Google account's backup settings.
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:
- Erase the light history at any time with "Clear history", or uninstall the app or clear its data to erase the light history and settings stored on your device
- Turn off notification access or "Display over other apps", or withdraw the phone permission, in your device settings at any time
- Contact us at the address below to make a request regarding the information we hold
9. Children's Privacy
Edge Lighting Pro 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.
