Where Sublandia Editor Stores Your Project Data

When you work in Sublandia Editor, it is important to understand where your project data is stored and what you should do to keep your work safe.

Sublandia Editor is designed for a browser-based local workflow. This means that project work can be stored locally in the browser while you edit, instead of being treated as a cloud-based project by default.

However, local browser storage should not be your only backup for important work. If you are working on a long, professional or client-sensitive subtitle project, you should also export a full project backup as a .subpro file.

This guide explains the difference between project data inside the editor, exported subtitle files and full project backup files.

Project Data During Editing

While you work in Sublandia Editor, your project data can exist inside the editor environment in your browser.

This can include information such as:

• subtitle lines
• timing changes
• text edits
• project settings
• language settings
• imported subtitle data
• video-related project information
• editing progress

This local workflow makes it possible to work on subtitle projects directly in the browser without turning every edit into a cloud upload process.

Browser Storage Is Not the Same as a Backup

Local browser storage is useful, but it should not be treated as a permanent backup.

Browser data can be affected by:

• clearing browsing data
• clearing site data
• using private or incognito mode
• browser storage limits
• changing devices
• changing browsers
• browser reset or reinstall
• system cleanup tools
• storage permissions
• accidental project deletion

For this reason, important subtitle projects should always be backed up manually.

The safest way to protect your work is to export a .subpro project file.

What Is a .subpro File?

A .subpro file is the Sublandia Editor project file.

It is used for exporting and importing full Sublandia Editor projects. Unlike a regular subtitle file, a .subpro file is designed to preserve the complete project context.

A .subpro file can include:

• project data
• video
• subtitle template
• subtitle lines
• timing information
• project settings
• language information
• other data connected to the project

Use .subpro when you want to save, transfer, restore or continue a full project later.

Recommended Backup Workflow

For a safer workflow, use both subtitle export and project export.

1. Work on the project in Sublandia Editor.
2. Save or keep your working progress inside the editor.
3. Export the final subtitle file when subtitles are ready.
4. Export a .subpro file to back up the full project.
5. Store the .subpro file in a safe location on your device or external storage.
6. Use clear file names with project name, language, date and version.

What Happens If You Change Device or Browser?

If your project data exists only inside local browser storage, it may not follow you to another device or browser.

To move a project safely, export it as a .subpro file and then import that file where you want to continue working.

Do not rely on browser storage alone when changing:

• computer
• browser
• browser profile
• operating system
• website/domain
• storage settings

A .subpro export gives you a portable project file that is easier to back up, transfer and restore.

What Should You Export?

There are two main types of export:

1. Subtitle export

Use this when you need the final subtitle file.

Examples:

• SRT
• TTML
• DFXP
• VTT
• ASS

This is usually the file you deliver or use for playback.

2. Project export

Use this when you need to save the full project.

Example:

• SUBPRO

This is the file you use for backup, transfer or continuing work later.

For important projects, it is best to export both.

Recommended Safety Checklist

Before closing the browser or finishing work for the day, check the following:

1. The latest subtitle edits are complete.
2. The project has been reviewed or saved at the current stage.
3. The final subtitle file has been exported if needed.
4. A .subpro backup has been exported for important work.
5. The backup file is stored somewhere safe.
6. The file name clearly shows project name, language and version.
7. You are not relying only on browser storage for important work.

This helps prevent accidental data loss and makes the project easier to continue later.

 FAQ

Where does Sublandia Editor store project data?

Sublandia Editor can keep project-related data locally in the browser while you work. This local data is connected to the device, browser and website/domain you are using.

 

Is my project stored in the cloud?

Sublandia Editor is designed for a browser-based local workflow. This means project work can happen locally in your browser instead of being treated as a cloud-based project by default.

 

Is browser storage permanent?

No. Browser storage should not be treated as a permanent backup. It can be affected by browser settings, clearing site data, storage limits, private mode, changing devices or using a different browser.

 

What is the safest way to save my project?

The safest way to save a full project is to export a .subpro project file. This gives you a backup that can be stored, transferred or imported later.

 

What is the difference between an SRT file and a .subpro file?

An SRT file is a subtitle file used for delivery or playback. A .subpro file is a Sublandia Editor project file that can contain full project data, including video, template and other project information.

 

Should I export subtitles or export the project?

For final delivery, export the subtitle file, such as SRT, TTML, DFXP, VTT or ASS. For backup or continuing work later, export the full project as a .subpro file.

 

Will my project appear on another computer automatically?

No. If the project only exists in local browser storage, it will not automatically appear on another computer. Export a .subpro file and import it on the other device.

 

Will my project appear in another browser automatically?

No. Local browser data is usually tied to the browser you used. A project created in one browser may not appear in another unless you export and import a .subpro file.

 

Can I lose project data if I clear browser data?

Yes. Clearing browser data or site data can remove locally stored project information. Export a .subpro backup before clearing browser data.

 

Can I work safely in private or incognito mode?

Private or incognito mode is not recommended for important projects because local data may not be kept after the session ends. Use normal browser mode and export .subpro backups for important work.

 

Does local storage replace project backup?

No. Local storage is useful while working, but it does not replace a manual .subpro backup.

 

When should I back up my project?

Back up your project whenever the work is important, before closing the browser, before clearing browser data, before changing devices and after major editing stages.
