Waste Tools (hereinafter referred to as "the App") is developed and operated by the developer (hereinafter referred to as "we", "us", or "our"). We are committed to protecting your privacy and handling your personal information with transparency and care. This Privacy Policy explains how we collect, use, store, and share information about you when you use our App, and the rights you have regarding your information.
Please read this Privacy Policy carefully before using the App. By tapping "I Agree" and continuing to use the App, you confirm that you have read, understood, and agreed to this Privacy Policy.
Legal Basis: Where required by law (including the GDPR and UK GDPR), we rely on your consent as the legal basis for processing device identifiers, usage data, and advertising-related data for analytics and personalized advertising. We obtain this consent through an in-app consent mechanism before such processing begins. For the operation, security, and core functionality of the App, we rely on our legitimate interests, which we have balanced against your rights and freedoms.
The HarmonyOS version currently does not use advertising services, initialize advertising SDKs, request advertising consent, or display rewarded, app-open, or native feed ads. Accordingly, the HarmonyOS version does not process device identifiers, network information, or ad loading, impression, click, or reward interaction data for advertising services.
On HarmonyOS, the App processes camera, microphone, location, and sensor information only when you actively use the relevant tools and grant the required system permissions. With your consent, system services may collect anonymous usage and crash information to improve stability. The HarmonyOS privacy settings do not display advertising-consent or ad-consent withdrawal options.
On iOS, consent to advertising services and consent to personalized advertising are separate. Personalized advertising is optional and off by default. If you do not select it, the App does not request Apple's system tracking permission for personalized advertising.
If you choose personalized advertising, the App requests Apple's App Tracking Transparency (ATT) permission before the first advertising SDK initialization. An advertising service may use the IDFA only when you both select personalized advertising and authorize tracking in Apple's system prompt, for personalized delivery, measurement, or attribution.
If you decline, restrict, or later withdraw system tracking authorization, or do not select personalized advertising in the App, the App does not use the IDFA for personalized ads. Advertising services may still show non-personalized or contextual ads and may process IP address, device model, OS version, network data, and other SDK-required technical data for ad delivery, frequency control, fraud prevention, and security.
You can stop future ad requests and clear cached ads in Settings → Privacy Policy → Withdraw ad consent. You can also change system tracking authorization in iOS Settings → Privacy & Security → Tracking. Withdrawal does not affect the App's core tools, but may affect ad relevance and fill.
| Information Type | Specific Fields | Purpose |
|---|---|---|
| Device and online identifiers | App-instance identifiers, device identifiers, advertising identifiers where available; on iOS, IDFA is used for personalized advertising only when you select it and authorize ATT | Analytics, advertising delivery, frequency capping, fraud prevention, and security |
| Device and app information | Device model, OS version, language, app version, app state, and screen characteristics | Compatibility, performance, diagnostics, and advertising adaptation |
| Network and advertising interaction data | IP address, network information, consent choice, ad load/impression/click/reward events | Consent management, ad requests, measurement, billing, frequency control, and fraud prevention |
| Information Type | Specific Content | Purpose |
|---|---|---|
| Launch Data | App launch time, launch count | To calculate Daily Active Users (DAU) and Monthly Active Users (MAU) |
| Feature Usage Data | Tool open counts, session duration | To understand user preferences and optimize product experience |
| Diagnostics | Crash-related device state, stack traces, and diagnostic information | To identify and fix stability issues |
| Information Type | Description |
|---|---|
| Approximate or Precise Location | Only when you actively use automatic location in the Local Weather tool or the Altitude Measurement tool, and grant the system permission, the App reads your current coordinates, city, and altitude-related information to show your city and calculate altitude. This information is used locally for the relevant function only, is not used for continuous background location, and precise location is not provided to third-party SDKs. |
| Information Type | Use, Purpose, and Method |
|---|---|
| Availability and real-time values of specific sensors | Only while you actively use functions such as the level, compass, shake interactions, dice, flashlight, or altitude measurement, the App checks whether the device supports specific sensors, such as the accelerometer, rotation vector, or barometer, and reads orientation, direction, shaking, or air-pressure values to provide the relevant function. This information is processed in real time on the device only, is not uploaded or shared with third parties, stops being monitored after you leave the relevant function, and is not collected continuously in the background. |
| Information or Permission | Use, Purpose, and Method |
|---|---|
| Camera | Only when you actively use measurement, mirror, beauty, QR-code scanning, or Pomodoro interactions, and grant the system permission, the App accesses the camera feed for live preview, recognition, or local processing. The feed is not uploaded unless you actively save or share it through the system. |
| Microphone | Only when you actively use decibel, sound, or blowing-interaction functions, and grant the system permission, the App captures sound for real-time volume analysis, voice effects, or interactions. Audio is processed on the device by default. Only when you actively use the system sharing feature is the audio you select provided to the system share target. |
| Images generated in the App | Only when you tap "Save to Photos" does the App write a photo taken, edited, or generated in the App to the system photo library. On Android 9 and below, the App requests write access to external storage to complete that action. The App does not read photos, videos, or other files already in your photo library or shared storage. |
| Notifications and exact alarms | Only when you use the Pomodoro timer, and grant the system permission where required, the App sends a local completion reminder and schedules a local alarm. They are not used for advertising notifications. |
This page applies only to the App's global data path. The following SDKs are initialized or asked to process data only after the corresponding in-app choice; Google consent messages may also be shown where required by law.
