What a private journal needs
End-to-end encryption for anything that leaves your device. Entries should be encrypted before upload, with keys the company never holds. If the service can show your entries in a web dashboard after a password reset, it can read them.
Local storage that works offline. Journaling happens at night, on trains, and in places without signal. The app should open and save entries with no connection.
An exit you can read. A journal is a decades-long record. If the only readable copy lives inside one app's database, the journal lasts as long as that app does. Plain text files avoid that problem.
memrynote: a daily journal as encrypted Markdown
memrynote stores one journal entry per day as a plain Markdown file in your vault, beside your notes and tasks. Each entry can start from your own templates and prompts, and a side panel shows the schedule, tasks, and linked notes for that date. Highlights and revisit reminders bring past entries back when they are relevant.
Entries never need to leave your device. If you sync, each one is encrypted on your machine with XChaCha20-Poly1305 and the server stores only ciphertext. No company account is needed to journal locally, and local use is free.
Because entries are Markdown files, your journal opens in any text editor and survives any app, including memrynote. You can bring an existing journal with you: memrynote imports Apple Journal, Markdown folders, and other note apps.
memrynote runs on macOS, Windows, and Linux today. Mobile apps are planned, so if you journal mainly on your phone, check the roadmap first.
Journal next to your day
Keeping the journal in the same vault as tasks and notes means an evening entry can see what you actually did that day, without copying anything between apps.
How other journaling apps compare
Day One encrypts new journals end to end by default and has apps for iPhone, iPad, Android, Mac, and the web; syncing across devices is part of its paid plans. Apple Journal is built into Apple devices and syncs through iCloud. Standard Notes offers Daily Notebooks for journaling on its paid Productivity plan, inside its encrypted note storage.
All three keep entries in their own app storage, with exports available. If you want entries as plain files on your own disk, or a journal that runs natively on Windows and Linux, memrynote is the option that does both.
| App | Where entries live | Platforms |
|---|---|---|
| memrynote | Plain Markdown files you own | macOS, Windows, Linux |
| Day One | Its own app storage | iPhone, iPad, Android, Mac, web |
| Apple Journal | Its own app storage | Apple devices |
| Standard Notes | Encrypted app storage | Web, desktop, mobile |
Start with the format
Features change every year; the storage format of your journal is what decides whether you can read it later. Choose an app that encrypts what it uploads and keeps the original as plain text you control. Then pick the prompts and rituals that make you write.
