DailyTxT is an encrypted Diary Web-App to write down your stories of the day and to find them again easily. It is written in Python Flask (Backend) and Vue.JS (Frontend) and meant to be run by Docker - supports AMD64 and ARM64.

You should definitely take a quick look at How to Use to see all the hidden features.

New features will now be added only rarely. However, the support remains and in a few years there will most likely be a completely rewritten version (including upgrade support).

💬 Please simply open a new issue if you have any information, problem, new feature idea, new translation or anything else! I usually reply quickly and the project will have long support - especially security support - (unless marked as deprecated) as I use it regularly myself.

⚠️ Please note when submitting ideas: The basic text-layout will not be changed -> Only one plain text will be saved for each day, to keep things simple!


  • Features
  • How to Use
  • Installation
  • Changelog


  • Encryption: Everything you write is encrypted before it's written to the server's storage. Even the admin can't read your private stuff!
  • File-Upload: You can upload arbitrary files for each day (128 MB max each). They are stored encrypted on the server as well.
  • Search: Support your memory by easily scanning your notes for any keyword and rediscovering details you may have almost forgotten.
  • Multi-Language-Support: The Web-App is currently available in German, English, Spanish and Chinese (simplified) translation. The language gets detected and selected automatically based on your browser's settings. More languages are easy to add - iff you provide me with the language-files! See client/src/lang/translations
  • Mobile: Responsive design for easy use on mobile screen. Additionally: allows installation "A2HS" (Add 2 Home Screen)
  • Multi-User-Spport: You can create multiple User Accounts. Each account uses its own encryption key - so there is no risk for a data breach.
  • Backup & Restore: You can export all data (decrypted) for backup-reasons in a zip-file and reimport the data later by uploading the zip.
  • Templates: Create templates, which you can reuse every day.
  • If you came from journey.cloud, you could try this script to import your text to DailyTxT.
  • 🌟 There also exists a separate CLI program to decrypt your files without a running server. Example use case: In 10 years your server is shut down but you still have your encrypted dailytxt-files and want to read them again.

How to Use

There are two cool Shortcuts you should know:

  • Move back/forth one day: Alt + / Alt +
  • Select the search field: Ctrl + F

Note on backup & restore:

You can only reimport/restore all data at once, that was exported before, it's not selective! The restored data is then the most recent data for each day and any previous data for that day was moved to the day's history.

Installation Quickstart

Simply use the docker-compose.yml file from the repo. Adapt it to your needs and run

docker-compose up -d
More detailed Installation

DailyTxT is intended to be run by Docker. There is an official docker image.

Use the docker-compose.yml file in this repo and adapt it. You see it here:

version: "3"

services: dailytxt: image: phitux/dailytxt:latest container_name: dailytxt restart: always environment: # That's the internal container-port. You can actually use any portnumber (must match with the one at 'ports') - PORT=8765

  - SECRET_KEY=<openssl rand -base64 32>

  # Set it to False or remove the line completely to disallow registration of new users.

  # Use this if you want the json log file to be indented. Makes it easier to compare the files. Otherwise just remove this line!

  # Set after how many days the JWT token will expire and you have to re-login. Defaults to 30 days if line is ommited.

  # Enable/disable a feature of DailyTxT to auto-check maximal once per hour if there's a newer version of DailyTxT available. Defaults to True if line is ommited.
  - "<host_port>:8765"
  # perhaps you only want:
  # "<host_port>:8765"
  - "</save/my/dailytxt-files/here/>:/app/data/"
  # Or perhaps if using on a windows enviroment:
  # "C:/Users/example/dailytxt/:/app/data"</pre> 

There are four important things that you should adapt to your needs:

  • Generate a secret_key by running openssl rand -base64 32 in your bash
  • You probably want to allow the registration on the first run, generate the necessary accounts, and then restart the container with disallowed registration!
  • Choose the port on your localhost.
  • Select a path, where your diary-files are saved beyond the container lifetime.

Then simply run

docker-compose up -d

If you do NOT use docker-compose, then simply run the following equivalent from bash (and see the info above to adapt it to your needs!):

docker run -p<host_port>:8765 -e "PORT=8765" -e "SECRET_KEY=<openssl rand -base64 32>" -e "ALLOW_REGISTRATION=True" -v </save/my/dailytxt-files/here/>:/app/data --name dailytxt -d phitux/dailytxt:latest

You will probably proxypass the container via Nginx or Apache2. Here is an example apache-configuration (which of course needs to be slightly adapted):

<VirtualHost *:443>
    ServerName dailytxt.mydomain.tld

SSLEngine On

Header always set Strict-Transport-Security "max-age=63072000; includeSubDomains"

ProxyPreserveHost On
ProxyRequests off
AllowEncodedSlashes NoDecode
ProxyPass / http://localhost:8007/ nocanon
ProxyPassReverse / http://localhost:8007/


You can now (Version >= 1.0.4) also run DailyTxT on a subpath.
