2. Who We Are
Phywiz is an Android application designed to provide educational and utility features related to physics and problem solving.
3. Types of Personal Data Collected
The App may process the following categories of personal data:
- Trackers and identifiers: cookie-equivalent mobile SDK identifiers, advertising IDs (such as Google Advertising ID), and analytics identifiers.
- Usage Data: interactions with app features, session times, screens visited, events, and preferences.
- Device and technical information: device model, operating system, app version, language, IP-derived region, and network status.
- Crash and performance data: stack traces, diagnostics, performance timings, and error telemetry.
- Information you provide directly: support requests, feedback, and communication content.
- Device permissions data: where enabled by you, data available through permissions such as microphone access for relevant in-app features.
We aim to collect only information reasonably necessary for clearly stated purposes and to minimize unnecessary data processing.
4. Purposes of Processing and Associated Services
We process personal data for the following purposes:
- App operation: delivering requested features, maintaining service continuity, and troubleshooting.
- Analytics: understanding aggregate feature usage to improve content, user experience, and reliability.
- Advertising: displaying ads, managing ad frequency, and measuring advertising performance.
- Security: preventing abuse, unauthorized access, and harmful activity.
- Support: responding to questions, support requests, and legal/privacy communications.
- Legal compliance: meeting legal obligations and responding to lawful requests.
Third-party tools used for these purposes may include:
- Google AdMob (advertising)
- Firebase Analytics (analytics)
- Firebase Crashlytics (crash reporting)
- Google Play Services and hosting/infrastructure providers
5. Legal Bases for Processing (GDPR/Equivalent Standards)
Depending on your location and applicable law, we rely on one or more of the following legal bases:
| Processing Activity | Legal Basis | Simple Explanation |
|---|---|---|
| Providing requested app services | Performance of a contract | We need certain data to deliver the app functionality you ask for. |
| Analytics, security monitoring, and product improvement | Legitimate interests | We use proportionate data to keep the App secure and improve quality. |
| Advertising personalization and certain tracking activities | Consent (where required) | In regions requiring consent, we process this data only after receiving your permission. |
| Regulatory reporting and lawful disclosure | Legal obligation | We process or disclose data when legally required. |
6. Permissions and Device Access
The App may request Android permissions only when needed for specific features. Permission prompts are shown by your device at runtime.
- Microphone permission (if enabled by feature): used only for audio-dependent functionality you choose to activate.
- Other runtime permissions: requested only when relevant to a specific action initiated by you.
You can manage or revoke permissions at any time in device settings. Some features may not function correctly if permissions are disabled.
7. Third-Party Services and Information on Opt-Out
Third-party providers may process personal data under their own privacy terms and legal frameworks.
For interest-based advertising, you can manage or opt out through resources such as:
- YourOnlineChoices: https://www.youronlinechoices.com/
- Digital Advertising Alliance (DAA): https://optout.aboutads.info/
- Network Advertising Initiative (NAI): https://optout.networkadvertising.org/
- Android ad personalization settings on your device.
9. Retention Periods
We keep data only as long as needed for the purpose collected, unless a longer period is required by law.
| Data Category | Typical Retention Logic |
|---|---|
| Technical logs and diagnostics | Usually retained for short operational windows (for example, 30-180 days), unless needed for security investigations. |
| Analytics and usage events | Retained for trend analysis and product improvement, then aggregated, anonymized, or deleted according to provider tools. |
| Support communications | Kept while a request is active and for a reasonable follow-up period, unless legal obligations require longer retention. |
| Advertising-related identifiers | Retained in line with ad partner settings, consent choices, and applicable legal requirements. |
10. Mode and Place of Processing
Data is processed using appropriate technical and organizational safeguards to prevent unauthorized access, disclosure, alteration, or destruction.
Processing may occur at the Data Controller's offices and at the offices of service providers involved in app operations.
