DevMate Privacy Policy (Android Global)

Effective date: July 5, 2026 Version: 2.0.0 Platform: Android Distribution region: overseas/global channels Developer: Beijing Chenghan Bowen Education Technology Co., Ltd. Contact: contact@chenghanbowen.com

1. Scope

This Policy applies to DevMate for Android distributed through overseas/global channels and related deeplink testing, command lookup, device information, memos, schedule/alarm reminders, developer tools, feedback, legal page, analytics, advertising, and support services.

2. Information We Process

• URLs, JSON, text, timestamps, colors, QR code content, commands, memos, schedules, reminder times, and reminder rules that you enter or generate. Unless you actively submit, share, or use an online feature, tool input is generally processed locally.
• Device information tool results. The app does not read Android ID as a general startup identifier; only when you actively open the Device Info tool does the app read Android ID through Android system APIs to display or copy it locally.
• QR/barcode content in the camera view when you actively scan, feedback content, contact details, screenshots or image attachments, and legal page parameters.
• After you consent, Firebase installation or instance identifiers, Google Advertising ID where allowed by system and Google policies, device/app information, network status, IP address, page/tap/crash events, ad impression/click/close events, consent state, and first-party promotion events.

3. Region-Specific SDKs and Services

• Firebase Analytics / Firebase Crashlytics: used only after privacy consent for basic analytics, crash diagnostics, and service stability.
• Google Mobile Ads / AdMob: used only after privacy consent and when ad configuration is enabled for ad requests, impressions, measurement, frequency control, and invalid-traffic prevention.
• Google User Messaging Platform: used in applicable regions to present advertising, privacy, or consent controls and to record consent state.
• First-party promotion center: used for our own app promotions, operating slots, impressions, clicks, and redirect statistics.

Third-party SDKs or services work only after you agree to this Privacy Policy, grant any required system permission, and enable the relevant feature or ad configuration.

4. Permissions and System Capabilities

DevMate Android Global may use network access, network state, camera, notifications, exact alarm, boot-completed broadcast, legacy storage/media selection, system file picker, clipboard write, WebView, Google Advertising ID, and advertising-consent related system capabilities. Restart recovery is used only while valid schedule/alarm reminders exist and is no longer used for reminder recovery after all valid reminders are deleted or disabled.

5. Your Rights

We do not sell your personal information. You can manage permissions and personalized-ad preferences in Android or Google settings, or contact contact@chenghanbowen.com to request access, correction, deletion, or withdrawal of consent. If this Policy differs from a feature-specific notice, the notice that better protects user rights will apply.
