Version: 1.0
Welcome to Wherex (Chinese name: 问处; hereinafter “the App” or “we”). This Privacy Policy explains how WLinger (website: undefined) collects, uses, stores, and protects information when you use the App.
Please read this policy carefully before using the App. By downloading, installing, or using the App, you acknowledge that you understand and agree to this policy. If you do not agree, please stop using the App and uninstall it.
1. Product positioning and core commitment
Wherex is a local-first personal inventory management app:
- Item names, photos, categories, locations, notes, backup files, and similar data you enter are stored only on your device by default (SQLite database and the app’s private directories). We do not upload this content to our servers.
- The App does not currently offer user account registration or cloud sync.
In this policy, “collection” mainly refers to device information, anonymous usage statistics, and diagnostic data processed to improve the product, display ads, and maintain stability—not your item content.
2. Information we collect
2.1 Information you provide (stored locally only)
| Type | Examples | Uploaded? |
|---|---|---|
| Item and organization data | Name, description, category, location, expiry | No |
| Media | Item photos (local app storage) | No |
| Backup files | ZIP exports you create | No (you keep them) |
| App settings | Theme, reminder thresholds, analytics toggle, etc. | No (on device) |
2.2 Anonymous usage statistics (optional; can be turned off)
To improve the product, when you enable Settings → Help improve Wherex, we may collect data through Firebase Analytics:
| Type | Examples | Notes |
|---|---|---|
| Usage events | Opening a screen, adding an item, exporting a backup | No item names, search terms, or photo paths |
| Event parameters | Whether a photo was added, whether expiry was set, item count ranges | Aggregated metadata only |
| App information | App version, operating system | For version and platform breakdown |
You may turn off this collection at any time under Settings → Privacy & improvement → Help improve Wherex. After you turn it off, we stop collecting new usage events via Firebase Analytics (existing anonymized aggregate data may be retained per Google’s policies; see below).
2.3 Diagnostics and crash information
To keep the App stable, we may collect through Firebase Crashlytics:
- Crash stack traces, error types, app version, device model, and OS version
- Does not include your item names, photos, or backup contents
Crash reporting is separate from the “Help improve Wherex” toggle. Turning off usage statistics does not disable crash reporting.
2.4 Advertising-related data
The App displays ads through Google AdMob (app open, banner, etc.). Ad services may collect:
Device advertising identifiers (e.g., Android Advertising ID, iOS IDFA—only if you authorize tracking)
IP address (for ad delivery and fraud prevention)
Ad interaction data (impressions, clicks, etc.)
Users in the European Economic Area (EEA) and similar regions may see the Google User Messaging Platform (UMP) consent flow.
iOS users may see the App Tracking Transparency (ATT) prompt.
You can manage ad tracking and personalization through system settings or consent dialogs. Ad data processing is governed by Google’s policies. See undefined.
2.5 What we do not collect
- Item names, full notes, or search keywords
- Item photos or backup ZIP contents
- Specific names of your categories or locations
- Precise GPS location
- Contacts, SMS, or call logs
3. How we use information
| Purpose | Legal basis / context |
|---|---|
| Core inventory features | Providing the service; data processed on your device |
| Anonymous usage statistics and product improvement | Your consent (withdrawable anytime) |
| Crash analysis and bug fixes | Legitimate interest / service quality |
| Displaying ads and measuring ad performance | Your consent (UMP/ATT, etc.) and Google’s terms |
4. Third-party SDKs and services
The App integrates the following third-party services:
| Service | Provider | Purpose | Privacy information |
|---|---|---|---|
| Firebase Analytics | Anonymous usage statistics | undefined | |
| Firebase Crashlytics | Crash reporting | Same as above | |
| Google AdMob | Advertising | undefined | |
| Google UMP | Privacy consent (EEA, etc.) | Same as above |
Third parties may process data outside your country (e.g., the United States or the European Union). We aim to minimize data collection and disclose this processing in this policy.
5. Storage and security
- Local data: Stored in the app sandbox on your device. Uninstalling the App removes the local database and photos unless you have backed them up elsewhere.
- Transmitted data: Statistics and crash data are sent to Google over HTTPS.
- Retention: Retention on Firebase/Google systems follows their product policies (Analytics events are often retained for about 2–14 months, configurable). We cannot delete anonymized remote statistics tied to a specific individual.
We use reasonable technical measures to protect data in transit but cannot guarantee absolute security. Please safeguard your device and backup files.
6. Your rights and choices
Depending on applicable law (including the Personal Information Protection Law of the People’s Republic of China where applicable), you may have the following rights:
| Right | How to exercise it |
|---|---|
| Know and decide | Read this policy; use the in-app toggle for usage statistics |
| Opt out of anonymous statistics | Settings → Help improve Wherex → Off |
| Manage ad tracking | iOS: Settings → Privacy → Tracking; Android: reset advertising ID; UMP consent options |
| Access / delete local data | Edit or delete items in the App; export data, then uninstall if desired |
| Complaints and inquiries | Email us at the address below |
We will respond within a reasonable period (within 15 business days where not otherwise required by law). We may not be able to delete specific remote records that are anonymized and not reasonably linkable to you; we will explain why when that applies.
7. Children
The App is intended for users aged 18 or older, or use under a guardian’s consent and supervision. We do not knowingly collect personal information from children. If you are a guardian and believe we have processed a child’s information without consent, please contact us to request deletion.
8. Changes to this policy
We may update this policy from time to time. Material changes will be communicated through in-app notice, website announcement, or similar means. Continued use after an update means you accept the revised policy. Please review periodically:
