Operator: Huanzhi Tech
Grid Diary is an offline-first, modular 3x3 reflective journaling application crafted by Huanzhi Tech. We believe your thoughts and daily memoirs belong solely to you.
1. Zero Cloud Uploads & Local Journaling
Grid Diary operates strictly on-device. Your thoughts, logs, and photos never leave your device.
- Local Storage: Grid entries, mood tags, habit checkboxes, expense entries, and attached photos are stored exclusively in your device’s private sandbox database.
- No Mandatory Account: Start journaling immediately without registering an account. Zero risk of remote database breaches.
- Zero Tracking: We include no analytics or behavioral tracking SDKs.
2. Permissions
| Permission | Usage Timing | Purpose | Network Upload |
|---|---|---|---|
| Photo Library (Read) | When you insert pictures into diary grids | Read user-chosen images locally | No (Local only) |
| Local Notifications | When you enable daily journaling reminders | Dispatch on-device reminder alerts | No (On-device timer) |
3. Export & Permanent Data Purge
- Open Export: Export all entries to open formats (Markdown / JSON) at any time.
- Permanent Purge: Clearing app storage in device settings or uninstalling Grid Diary permanently erases all journal records from physical storage.
