Web app

An online diary you can open from any browser

Purple Diary is an online diary that lives in your browser. Open the web app, sign in, and start writing with nothing to download. The same private journal then syncs to your phone, tablet, and computer, so where you write never decides where you can read.

Write from any browser, nothing to install

The Purple Diary web app lives at diary.colorhub.online. Open it in Chrome, Safari, Firefox, or Edge, sign in, and you are writing. There is no installer, no setup wizard, and no waiting for an update to download. That makes it the quickest way to start an online diary, and a handy fallback when you are on a device where you cannot, or would rather not, install anything.

The web version is a real editor, not a stripped-down note box. You get the same comfortable writing space, with your past entries, moods, and tags right there. Start a thought at your desk in the browser, and it is waiting on your phone by the time you are on the train home.

The same diary, in sync everywhere

An online diary is most useful when it is not only online. Purple Diary syncs your entries across iPhone, iPad, Apple Watch, Mac, Android, Wear OS, Windows, and the web. Write in the browser today, add a few lines from your phone tomorrow, and review the week on your Mac at the weekend. It is one journal that follows you, not separate copies you have to keep matching up by hand. If you want the full picture, the cross-platform diary app page covers how every device fits together.

Privacy still holds online

Writing in a browser should not mean giving up the things that make a diary safe to keep. Purple Diary shows no ads, does not sell your data, and does not read or reuse the content of your entries for anything other than running the app for you. On the mobile and desktop apps, the app lock with a PIN and biometric unlock keeps your journal closed until it is really you opening it, and that same private journal is the one you reach through the web. Your online diary is a place to be honest, not a profile for someone else to mine.

When a web diary is the right tool

There are days when the browser is simply the only practical door to your journal. A few examples where the online diary earns its place:

• A work computer. You may not be allowed to install apps, but you can still open a browser tab on a break and write a few private lines.
• A borrowed or shared machine. Sign in, write, and sign out again without leaving an app behind on someone else's device.
• A new or reset device. Before you reinstall anything, you can reach your whole diary from the web and pick up exactly where you left off.
• A big writing session. Some people just prefer a full keyboard and a wide screen for longer entries, and the web app makes that easy.

Purple Diary is rated 4.5 stars by more than 500 people across its apps, and the option to open the same journal anywhere is part of why it fits so many routines. If you prefer an installed app on your main device, the digital diary app page walks through the native versions.
