Sync notification time info to calendar automatically
About this app
⚠️ Note: This app is designed specifically for Simplified Chinese environment and only supports Chinese time expression parsing.
Automatically create calendar events from notifications received from work and social apps by parsing Chinese time expressions.
Features:
• Automatically recognizes Chinese time expressions in notifications (e.g., "明天下午3点" = tomorrow 3pm, "周五晚上8点" = Friday 8pm) • Supports rich Chinese relative time parsing ("3天后" = in 3 days, "1个半小时后" = in 1.5 hours) • Supports fuzzy time expressions ("今晚" = tonight, "下午" = afternoon, "周末" = weekend) • Customizable keyword filters and app whitelist • Multiple calendar selection support • Fully offline, no internet permission required • Privacy-respecting, data never leaves your device
Use Cases (Chinese social/work apps):
• WeChat/QQ group notifications: "明天下午3点开会" (meeting tomorrow 3pm) • Work notifications: "周五晚上8点项目汇报" (project report Friday 8pm) • Social plans: "下周二一起吃饭" (dinner together next Tuesday)
Permissions:
• Calendar access: Read and create calendar events • Notification access: Read system notifications to extract time information • Foreground service: Keep service running in background • Exact alarm: Used for crash recovery mechanism • Query packages: Used for app picker to display installed apps
This app contains no ads, tracking, or data collection.
Target audience: Chinese-speaking users who use Chinese messaging and social apps.
Note: Github Release version uses private signing, although both are built automatically by Actions, the signatures of the two packages are different.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be top.stevezmt.calsync is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 0.2.0-rev2-foss is the last build before it. Android will not install an older version code over a newer one, so you must uninstall CalSync - Notification Calendar Sync first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of CalSync - Notification Calendar Sync, and a listing is removed when the evidence for it stops holding up.
