Files uploaded to ZeroTwo are stored securely in your personal account storage. This page explains where files live, how long they persist, and how to manage, delete, or export them.

​
Where Files Are Stored

ZeroTwo uses per-account Supabase storage for all uploaded files. Each ZeroTwo account has its own isolated storage bucket — your files are never mixed with another user’s files.

​
How Long Files Are Kept

Files are retained indefinitely until you explicitly delete them or close your account. There is no automatic expiration, no rolling deletion after a period of inactivity, and no storage cap that triggers deletion.
EventEffect on Files
Session ends / you log outFiles remain in storage
Chat is deletedFile is retained in Files Library; only the chat reference is removed
Project is deletedFiles are not automatically deleted; they remain in your main Files Library
Account closedAll files are permanently deleted as part of account closure

​
Project File Scoping

Files uploaded within a project are scoped to that project:
  • Project files appear in the project’s Files tab, separate from your general uploads
  • Project files also appear in the main /files library, tagged with the project name
  • Deleting a project does not automatically delete its files — delete them from /files if needed
File privacy is maintained at both the account and project level. Even within a shared workspace, files are associated with the uploading account.

​
Viewing Your Storage Usage

A storage usage summary may be visible in Settings → Account. You can also review your files manually in the Files Library at /files — the library shows each file’s size, so you can assess usage directly.

​
Deleting Files

File deletion is permanent and cannot be undone. ZeroTwo does not retain backups of user-deleted files. Download any files you want to keep before deleting.

​
Delete a Single File

1

Open the Files Library

Navigate to /files or click Files in the topbar.
2

Find the file

Use the search bar or scroll to locate the file you want to delete.
3

Hover over the file

Move your cursor over the file entry — action icons appear.
4

Click the delete icon

Click the trash can icon. A confirmation dialog appears.
5

Confirm deletion

Click Delete in the confirmation dialog. The file is permanently removed from storage.

​
Delete All Files at Once

To clear all files from your account at once:
  1. Go to Settings → Data Controls.
  2. Find the Clear Files option.
  3. Click Clear All Files and confirm.
This removes every file from your account permanently.

​
Delete Project Files

To delete files scoped to a specific project:
  1. Open the project from the sidebar.
  2. Navigate to the project’s Files tab.
  3. Hover over a file → click the delete icon → confirm.
Project files also appear in the main /files library tagged with the project name, where you can delete them the same way.

​
Effect on Chat History

Deleting a file affects future access but does not erase existing AI analysis from your chat history:
  • Chat messages referencing the deleted file still show ZeroTwo’s responses and analysis
  • The raw file attachment link will no longer resolve — you cannot re-download the file from the chat
  • The text content of all AI responses remains fully intact and accessible
Think of it as removing the source file while keeping the work already done with it.

​
Downloading Files

Before deleting, or any time you want a local copy, download files from the Files Library:
  1. Navigate to /files.
  2. Hover over the file.
  3. Click the download icon that appears.
  4. The file downloads to your device’s default downloads folder.
The downloaded file is identical to your original upload — ZeroTwo does not modify or re-encode uploaded files.

​
Data Export

To export all your account data including file metadata:
  1. Go to Settings → Data Controls → Export Data.
  2. A ZIP archive is generated containing your chat history, account data, and file metadata.
  3. You will be notified when the export is ready to download.
The data export includes file metadata (filenames, upload dates, sizes) but not the file binaries themselves. To export the actual files, download them individually from /files before requesting the data export.
If you are planning to close your account or switch plans, export your data and download important files first. Once an account is closed, files cannot be recovered.
