Privacy Policy¶
Effective Date: September 2026
Thank you for using LED Flow (the "App"), provided by Androxus ("we," "us," or "our"). This Privacy Policy explains what the App collects, what it does not, and what you can control.
Overview¶
LED Flow shows ads and uses Firebase to understand app usage, purchases and crashes. It does not collect the message you scroll or your message history.
The short version:
- Your scrolling message and your message history stay on your device. They are never sent to us
- The App shows ads in the free version; buying Pro removes them
- Firebase Analytics is active by default in the published App; there is currently no in-app toggle to turn it off
- No accounts, no sign-in, and we operate no server of our own
- Your style choices, settings and message history stay on your device
What leaves your device¶
| What | When | Where it goes | Can you stop it |
|---|---|---|---|
| Advertising and device data | Ads shown in the free version | Google AdMob | Buy Pro to remove ads entirely |
| App usage events (listed below) | Always, in the published App | Firebase Analytics | No in-app toggle currently |
| Crash reports | When the App crashes or logs a handled error | Firebase Crashlytics | No |
| Purchase confirmation | When you buy or restore Pro | Google Play Billing | Required to purchase |
Nothing on this list includes the text you scroll or your message history.
Advertising¶
The App shows ads from Google AdMob in five places: an app open ad when you return to the App, a banner on the main screen, a banner when a free user backs out of the main screen, a native ad in the corner of the full-screen LED display, and an interstitial (full-screen) ad after you close that display.
Buying LED Flow Pro removes every ad.
Consent. Where required by Google, such as in the EEA and UK, the App shows Google's User Messaging Platform (UMP) consent form on first launch. The Mobile Ads SDK is initialised, and ads may already be requested, at app startup independently of when or how you respond to that form. There is currently no in-app option to review or change your consent choice afterwards; you can manage ad personalisation for your Google account from Google's own Ads Settings.
When an ad is shown, AdMob may receive your advertising ID, device and app information, IP address and your interactions with the ad, and may use them to personalise advertising. See the Google Privacy Policy and how Google uses data from partner apps.
Analytics¶
The App uses Firebase Analytics, and it is active by default in the published version of the App; there is currently no in-app toggle to turn it off. It records these events and nothing else:
| Event | Meaning |
|---|---|
feedback_card_shown |
The in-app "are you enjoying LED Flow" card was shown |
upgrade_card_shown |
The Pro upgrade card was shown |
interstitial_ad_shown |
A full-screen ad was shown |
support_screen_open |
The upgrade screen was opened |
purchase_button_tapped |
You tapped a purchase button |
purchased_successfully |
A purchase completed |
purchase_acknowledged_later |
A purchase was confirmed with Google Play after the fact |
invalid_purchase_signature |
A purchase receipt failed verification |
grace_period_over / inside_grace_period |
Whether a lapsed subscription's grace period has ended |
new_uuid_generated / old_uuid_used |
A random identifier used to request one ad banner was created or reused |
That is the complete list. There is no event for the message you type, for opening the app, or for your Look & Feel choices. Firebase also derives standard information such as an app instance identifier, device model, operating system version and approximate country from your IP address.
Crash reporting¶
The App uses Firebase Crashlytics to record crashes and handled errors. A crash report contains the stack trace, device model, operating system version and app state at the time. It does not contain your scrolling message or history.
Crash reporting is not currently exposed as a user-facing toggle. If you would prefer not to send crash reports, contact us.
Remote configuration¶
The App uses Firebase Remote Config to fetch a small number of feature flags, refreshed at most about once an hour, and sends no personal information.
Purchases¶
If you buy LED Flow Pro, whether as a yearly subscription, a monthly subscription, or a one-time lifetime purchase, the transaction is handled entirely by Google Play. We never see or receive your payment details. The App verifies your entitlement with Play when it starts. See the Google Play Privacy Policy.
Permissions¶
| Permission | What it's used for | What happens to the data |
|---|---|---|
| Internet | Loading ads, Firebase traffic described above, and checking your Google Play purchase | See the table at the top |
| Notifications (Android 13+) | Asked during setup, for possible future battery or charging alerts | The App does not currently post any notifications |
| Wake lock | Declared by the App | Not currently used by any App code |
| Receive boot completed / app updated | Lets the App know when your device restarts or the App is updated | The App does not currently take any action on these events |
| Advertising ID | Added automatically by Google's ad SDK, not declared by the App itself | Used by AdMob to personalise and measure ads, see Advertising above |
What's stored on your device¶
LED Flow stores the following only on your device:
- The message you're currently scrolling
- Your last 100 messages (History), until you delete them or uninstall the App
- Your style choices: font, text colour, background colour, dot pattern, size, gap, speed, direction and effects
- Settings: theme, language, double-tap-to-exit, dim timeout and burn-in protection
- Temporary GIF files created when you share a banner, removed from your device automatically
None of this is uploaded to us.
Data we do not collect¶
To be explicit, LED Flow does not collect, store off device, or transmit to us:
- Your scrolling message or message history
- Your photos, files or contacts — the App does not request access to any of them
- Your precise location
- Your screen content or other apps' notifications — the App has no accessibility service and no notification-reading component
- Your name, email address or any account identity
