Your journal is a private record of your thoughts, experiences, and personal growth. Choosing to transition to a new diary application is a big decision, especially if you have accumulated years of logs. When moving to an offline-first, privacy-focused home like Euthy Journal, you don't have to leave your past behind.

Because Euthy Journal prioritizes extreme privacy, your database is kept locally on your device. All data imports are processed directly in the app, meaning your personal thoughts never touch our servers or any third-party cloud. Below, we've outlined the exact steps to migrate your logs from Day One, Journey, and other supported platforms into Euthy Journal.

Why Migrate to Euthy Journal?

Traditional journaling apps often store your entries in centralized cloud databases. While this makes synchronization easy, it exposes your most intimate logs to server-side data breaches, indexing, or monetization. Euthy Journal is built on a different philosophy:

Local-First Database: Fast, offline-first reactivity powered by TinyBase and SQLite.
Sandboxed Security: Protected by your operating system's application sandbox and optional biometric PIN locks.
Private Sync: Sync your data using your own Google Drive container, maintaining full ownership.
No Accounts Required: Start journaling instantly without email addresses, phone numbers, or passwords.

Step 1: Exporting Your Data from Previous Apps

To move your data, you must first export your logs from your current app in a format that Euthy Journal can understand (specifically standard JSON, CSV, or structured ZIP files containing your logs and media files).

Option A: Exporting from Day One

Day One allows exports in several formats. For the cleanest transfer of text, tags, dates, and locations, we recommend their official JSON export format:

Open the Day One app on your mobile device.
Tap the Settings icon (usually a gear in the sidebar or profile section).
Navigate to Import/Export.
Tap Export Journal and select JSON as the format.
If you have multiple journals, select all journals you wish to migrate.
Tap Export and save the resulting .zip archive to your device's local filesystem or a secure folder.

Option B: Exporting from Journey

Journey allows you to export your data as a structured ZIP containing JSON files representing your entries along with your photos and media:

Open the Journey app on your device, or log in to Journey.cloud on your web browser.
Go to Settings -> Cloud.
Under the sync settings or backup tab, select Export.
Choose to export your journal entries as a ZIP file.
Download and save the resulting ZIP archive directly to your device's filesystem.

Option C: Exporting from Other Supported Apps

Euthy Journal includes custom importers for several other popular reflection tools. Follow these steps to obtain a compatible backup format:

Daylio: Open Daylio -> Settings -> More -> Export entries -> Select Export CSV (or ZIP containing the CSV).
Diarly: Open Diarly -> Settings -> Export -> Select Export as ZIP archive (contains Markdown entries and media).
Diarium: Open Diarium -> Settings -> Import & Export -> Select Export to JSON.
Stoic: Open Stoic -> Settings -> Export Data -> Export as a ZIP file (containing CSV logs).
Universum: Open Universum -> Settings -> Export -> Save as a ZIP archive.

A Note on Media and Attachments

Euthy Journal's advanced import wizard fully supports media files for select formats. If you are importing a ZIP backup from Day One, Journey, Diarly, or Universum, the importer will copy and link your photo, video, document, and audio attachments directly. Other text-based formats (like CSV and JSON from Daylio, Diarium, or Stoic) will import text logs, moods, and tags cleanly.

Step 2: Importing into Euthy Journal

Once you have the export file saved on your device, importing it is quick and simple using Euthy's local import tool:

Open the Euthy Journal app.
Tap the Settings tab located at the bottom-right corner of the navigation bar.
Scroll down to the Backup & Export section and select Import Data.
An Import Wizard modal will appear. Select your target import source (e.g. Journey (ZIP), Daylio (CSV), Day One (ZIP), etc.).
Use your device's native file picker to select the backup file you exported in Step 1.
The local parser will begin processing your entries. You will see a progress bar indicating the number of entries parsed.
Once complete, tap Confirm. The application will restart automatically to reload the local database, and your timeline will populate with your reflection history.

Troubleshooting Common Migration Issues

If you encounter issues during your migration, check these common troubleshooting scenarios:

Unsupported File Type: Ensure you select the correct file format (.zip, .csv, or .json) as required by the Import Wizard. Standard PDF or raw text exports cannot be parsed automatically, as they lack structured metadata like mood tags or exact timestamps.
Extremely Large Files: If you are importing over a decade of entries with thousands of attachments, the device's local memory may experience a brief load. Keep the app in the foreground and ensure your screen does not turn off to prevent the system from pausing the import.
Time Zone Offsets: Euthy Journal stores all dates in UTC ISO strings and uses your local system clock to group entries by day. If some imported entries appear on a different day, verify that your previous app's timezone settings matched your current device configuration when the export was created.

Take Control of Your Journaling

Migrating your database is the first step toward a healthier, more secure, and completely private relationship with your diary. With Euthy Journal, your thoughts are yours alone—stored safely on your physical device, away from prying eyes, with performance that feels smooth and immediate.
