Tiday Privacy Policy (Android China)
Version 2.3.1. Effective date: 2026-10-19. Applies to the android / cn release.
Platform: Android Distribution region: mainland China channels Developer: Beijing Chenghan Bowen Education Technology Co., Ltd. Contact: contact@chenghanbowen.com
1. Scope
This Policy applies to Tiday for Android distributed through mainland China channels and related schedule management, calendar, memos, local reminders, feedback, legal page, analytics, advertising, first-party promotion, and support services.
2. Basic Service Mode
You may choose Basic Service first. In Basic Service mode, the app does not initialize analytics or advertising SDKs, request ads, enable personalized ad recommendations, or report to the first-party promotion center, while local schedules, calendar, memos, and basic browsing remain available.
3. Information We Process
- Schedule titles, notes, reminder times, repeat rules, ringtone or reminder settings, calendar preferences, memo content, and local restoration state. These items are mainly processed locally unless you actively submit feedback, share, or use an online service.
- Feedback content, contact details, screenshots or image attachments, app version, device model, system version, channel, installation instance ID, and legal page parameters.
- After you consent, Android ID, OAID/GUID, device/app information, network status, IP address, page/tap/crash events, ad impression/click/close events, and first-party promotion impression, click, and redirect events.
4. Region-Specific SDKs and Services
- Umeng mobile analytics: used only after privacy consent for basic analytics, channel analysis, and diagnostics.
- GroMore / Pangle advertising SDK: used only after privacy consent and when ad configuration is enabled for ad requests, impressions, clicks, frequency control, measurement, and anti-fraud.
- First-party promotion center: used for our own app promotions, operating slots, impressions, clicks, and redirect statistics.
- Android WebView, system file picker, system alarm, and notification capabilities: used for legal/page display, feedback attachments, and local reminders.
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.
5. Permissions and Opt-Out
Tiday Android China may use network access, network state, notifications, exact alarm, boot-completed broadcast, legacy storage/media selection, the system file picker, WebView, and advertising-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. You can limit personalized ad recommendations in app settings and manage notification, alarm, and reminder permissions in system settings.
System broadcasts and reminder restoration
To restore local reminders that you actively configured, the app may receive five system broadcasts: device boot completed (android.intent.action.BOOT_COMPLETED), system time changed (android.intent.action.TIME_SET), time zone changed (android.intent.action.TIMEZONE_CHANGED), this app's package replaced (android.intent.action.MY_PACKAGE_REPLACED), and the exact-alarm permission state changed (android.app.action.SCHEDULE_EXACT_ALARM_PERMISSION_STATE_CHANGED). These broadcasts may wake the app in the background (self-start), but only to re-register the local reminders you configured after boot or the relevant system-state change. They are not used to open a foreground page, for promotional re-engagement, or to launch or trigger the launch of another app.
The receiver is enabled only after you have consented to this Policy and while a valid local reminder exists on the device. Before consent, after consent is withdrawn, or when no valid local reminder exists, the receiver remains disabled. This feature only re-registers this app's local reminders and does not send reminder content to any third party.
6. Your Rights
We do not sell your personal information. You can manage permissions in Android 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.
Children's Personal Information Protection Rules
This is a standalone children's personal information section within this Privacy Policy. “Child” means a minor under 14. Tiday is a general schedule tool and is not specifically directed to children.
When the app is first opened or asks for privacy consent again, if the user may be under 14, a guardian should read this section and this Policy first and decide whether to consent. Before guardian consent, you may continue to use Basic Services that do not depend on that consent. Processing that needs separate consent or an active request occurs only when its stated conditions are met. We do not ask children to provide a birthday, age, identity document, or similar information for routine use.
Current processing facts for this platform:
- Local content: Schedule titles, notes, reminder times, repeat rules, ringtone or reminder settings, calendar preferences, and clipboard content that you actively copy or paste continue to be processed mainly on the device for schedules, memos, reminders, and text input. The three platforms currently provide no account registration or sign-in.
- Active feedback, installation, device, and SDK data: When you actively submit feedback, feedback content, contact details, screenshots or image attachments, app version, channel, device maker/model, OS version, and installation ID are used for issue submission, diagnosis, and response. Android Umeng analytics, GroMore/Pangle advertising, and first-party promotion continue to use the Android ID, OAID/GUID, device/network/IP data, sensor list, app events, ad events, and promotion events described in the relevant sections of this Policy.
The retention period, storage location, sharing scope, and handling by third-party services for children's information are described in the corresponding storage, sharing, and third-party service sections of this Policy. When a guardian makes a request, we handle it under this Policy and applicable law; previously submitted feedback or saved data is not automatically deleted.
A guardian may contact contact@chenghanbowen.com to request access to, correction or deletion of children's personal information, or withdrawal of the related consent. To prevent impersonation, we perform only necessary and proportionate verification for an application. If we discover that children's personal information was processed without guardian consent, we will stop the related processing and delete or anonymize it as required by applicable law.
Privacy Choices and Withdrawal
Use the app's Privacy Choices/Privacy Management entry in Settings to review the current state or choose again. If you previously consented, confirm “Withdraw Privacy Consent” before switching to Basic Services; canceling that confirmation leaves the existing choice unchanged. Resuming the relevant optional features requires your explicit consent and does not replay prior ad requests or impressions.
Withdrawal cancels current ad preparation and pending presentation, stops new advertising requests, and disables optional analytics and diagnostics controlled by the app. Basic features that do not depend on that consent remain available. SDK base instances, system diagnostics, or vendor-automatic behavior may still exist or run; this does not mean all SDKs automatically stop and does not guarantee zero SDK activity before consent. Withdrawal does not affect processing already lawfully completed or automatically delete submitted feedback or previously saved data. Deletion requests use the existing contact and handling procedures.
The app's main privacy choice is separate from system permissions and personalized-ad settings. Limiting personalization neither withdraws main privacy consent nor means ads process no information. This CN shell does not add the Global Google/Firebase/AdMob/UMP route. Any ATT system authorization that actually applies on iOS does not replace the app's main privacy choice.
