I sat in the cafe for a while and finally understood the thing that had been hanging over me. No need to explain it yet...

I left myself one small decision: explain less this month, sleep a little more. Some thoughts are better saved quietly...

The diary key stays with me. Entries are encrypted first, then sent away.

Use cases

For writing that should stay personal

Murmur is not a public feed or a collaborative document. It is a private diary space for thoughts that need to be written down, but do not need to be explained to anyone else.

Mood Journal

Track emotional changes, pressure points, and recovery patterns in a place you can revisit over time.

Daily Reflection

Keep the decisions, ideas, and small reminders that mattered today in your own long-term record.

Private Notes

Save content that does not belong in public notes, protected by a diary key and a local privacy lock.

Core features

Built for long-term journaling

Fast Capture

Open and write immediately, whether it is a passing thought, a mood shift, or a daily review.

Diary Key

Your entries are encrypted with a diary key. If you forget it, old entries cannot be recovered.

Privacy Lock

Add a 4-digit local lock that protects access when you leave the app.

Multiple Devices

Sign in with the same account and enter the correct diary key to view your history.

Privacy first

Plain text never leaves your device

Murmur has a simple design goal: support, developers, and servers should not be able to read your diary. The app syncs encrypted content only, and your diary key is never uploaded.

FAQ

About Murmur private diary

What is Murmur for?

Murmur is for private diary entries, mood notes, life fragments, daily reflections, and thoughts you want to keep personal instead of publishing or sharing.

Why does Murmur use local encryption?

Your diary entries are encrypted on your device with your diary key before they sync to the cloud. The server stores encrypted content, not readable plain text.

Can old entries be recovered if I forget my diary key?

No. The diary key is not uploaded to the server, so forgotten keys cannot be used to recover already encrypted entries. This prevents the server or developers from bypassing your key.

Do I need to download a native app?

No. Murmur opens in the browser and can be installed as a PWA on supported desktop and mobile browsers.
