HeartNote Diary

Keep your journal on your device. Capture text, photos, audio, video, files, and drawings—then revisit them with tags, four timeline views, and local backups.

HeartNote is an offline-first private journaling app focused on privacy, security, and a calm writing experience.

Your entries, photos, audio, video, files, and doodles are stored locally on your device by default. No account is required, and your data is not forced into the cloud.

HeartNote helps you capture everyday life in richer ways. In addition to plain text, you can write with images, image groups, video, audio, files, and doodles. The editor supports mixed media layouts, flexible block reordering, and Markdown text, so writing feels natural and expressive.

HeartNote also helps you organize and revisit your memories with:

Timeline and calendar views Notebooks, tags, weather, and mood metadata Search and filters Media library for browsing attachments On This Day, trends, and review insights Time Capsule reminders for future reflection For privacy and protection, HeartNote supports app lock, PIN, biometric unlock, and local backup and restore, so your journal stays under your control.

This version also adds:

Multi-year diary Notebook-based journal export Direct journal creation from a selected calendar date Export a single entry as a shareable journal card If you want a journaling app that stays private, works offline, and supports rich content, HeartNote is built for long-term personal use.
