Privacy Policy
Last updated: 12 June 2026
This privacy policy describes how powerapps.ai ("we", "us", "our") handles information when you use our mobile applications on Android or iOS (each, an "App").
1. Who we are
Developer: powerapps.ai
Contact e-mail: leovu2022@gmail.com
We are the data controller for the limited data our Apps collect. Google (Firebase, AdMob, Play Billing, ML Kit, and cloud AI services where used), Apple (App Store billing), and similar platform providers act as data processors on our behalf for the services they provide.
2. What stays on your device
Depending on which App you use, these activities typically happen on your phone or tablet and are not uploaded to our servers:
- Storing photos, documents, workout progress, meal logs, vocabulary entries, and other content you create or import.
- Running on-device recognition, translation, or other processing using platform libraries (for example Google ML Kit) where the App supports it.
- Downloading language packs, models, or other resources directly from the platform provider and keeping them on your device.
- Rendering results and saving exports locally.
We do not operate backend servers that receive or store your photos, documents, workout body images, vocabulary library, or similar personal content.
3. Information we do collect
3.1 Anonymous usage analytics — Firebase Analytics
We use Google Firebase Analytics to understand which features are used and to improve our Apps. Firebase Analytics may automatically collect:
| Data | Purpose | Linked to identity? |
|---|---|---|
| App events (screen views, feature taps) | Improve UX | No |
| Approximate location (country / region, derived from IP) | Aggregate analytics | No |
| Advertising ID (Android AAID / iOS IDFA where available) | Audience analytics | Pseudonymous |
| Device & OS info (model, OS version, language, time zone) | Bucket analytics | No |
| App version, installer source | Release health | No |
| Crash & ANR signals | Stability monitoring | No |
We do not set custom user IDs, we do not track precise GPS location, and we do not collect contacts, microphone audio, or the content of your photos or documents through analytics.
3.2 Crash and stability reports — Firebase Crashlytics
When an App crashes or hangs, Crashlytics may send a stack trace and minimal device state (model, OS version, app version, free memory, foreground/background state, locale). Crashlytics does not collect personally identifiable information unless the App explicitly attaches it — we never attach any.
3.3 Advertising — Google AdMob
Some of our Apps display ads served by Google AdMob. To request and tailor those ads, AdMob may collect:
| Data | Purpose |
|---|---|
| Advertising ID (AAID / IDFA) | Ad personalisation and frequency capping |
| Approximate location (country / region, from IP) | Regional ad targeting |
| Device & OS info | Ad fill compatibility |
| Ad interaction events (impressions, clicks) | Billing & fraud detection |
Google is the data controller for AdMob ad-serving data; their policy applies: https://policies.google.com/technologies/ads.
Where local law requires it (for example in the European Economic Area or United Kingdom), an App may show Google's User Messaging Platform (UMP) consent form and expose a "Manage privacy choices" entry in Settings so you can change your consent at any time.
You can also reset or opt out of personalised advertising in your device settings:
- Android: Settings → Google → Ads → Delete or reset advertising ID.
- iOS: Settings → Privacy & Security → Tracking, or limit ad tracking in Privacy settings.
The App will continue to work; ads may simply be less relevant.
3.4 Cloud AI features
Some Apps offer optional AI-powered features (for example word explanations, workout plan generation, or similar assistance). When you use those features, the App may send the minimum text or prompts required to fulfil your request to a cloud AI provider (such as Google Gemini). We do not use that content to build advertising profiles, and we do not store it on our own servers.
3.5 In-app purchases and subscriptions
If you buy a premium upgrade or subscription, payment is processed by Google Play Billing (Android) or the Apple App Store (iOS). We never see your card details. The store sends us only a purchase receipt or token, which we verify on your device to unlock features.
4. Permissions
Our Apps request only the permissions needed for the features you use. Common examples include:
| Permission | Why |
|---|---|
INTERNET | Ads, analytics, subscriptions, cloud AI features, and downloading on-device models |
ACCESS_NETWORK_STATE | Avoid unnecessary network calls when you are offline |
| Camera or photo library access | Capture or import images when a feature requires it |
| Notifications (if offered) | Optional reminders you choose to enable |
We do not request broad background location, contacts, calendar, or microphone access unless a specific feature clearly needs it and you grant permission.
5. Children
Our Apps are not directed to children under 13. We do not knowingly process data from children. If you believe a child has used one of our Apps, contact us and we will assist.
6. Where data is processed
Firebase, AdMob, Play Billing, App Store, ML Kit, and cloud AI services process data in regions where their providers operate, including the European Economic Area, the United Kingdom, the United States, and other countries, subject to their data protection terms (Firebase data processing terms).
7. How long we keep data
- Firebase Analytics: default 14-month retention, then aggregated.
- Crashlytics: default 90 days for individual crash reports.
- AdMob: per Google's ad data policies.
- Content on your device: until you delete it or uninstall the App.
We do not retain user content on our own servers.
8. Your rights
Depending on where you live (GDPR, CCPA, etc.) you may have rights to:
- request access to the data we hold about you,
- request deletion,
- object to processing for advertising,
- withdraw consent.
To exercise any of these rights, e-mail us at the address above. You can also:
- Delete or reset your advertising ID in device settings.
- Uninstall the App, which stops data collection from your device immediately.
- Use in-app Settings to manage ad consent where available (EEA/UK).
9. Security
Network traffic from our Apps uses HTTPS. Platform-provided downloads (such as on-device models) are verified by the provider's infrastructure. We do not store your personal content on our own servers.
10. Changes to this policy
We will update this page when our data practices change and update the "Last updated" date at the top. Substantial changes may also be noted in an App's release notes.
