Background

Users want clarity on where their PDFs and media files are stored. They're asking about:

Storage Location: Where are PDFs/media files saved?
Cloud Options: Should we use S3 or private cloud storage (Google Drive, etc.)?
Admin vs User Data: Should S3 be for admins/foundation data only?

User Questions

Storage Provider Recommendations

S3: Good for admin/system data, but user data privacy concerns
Private Cloud (Google Drive): Better for user data privacy and ownership
Hybrid: Admin content on S3 + User personal files on user-chosen cloud

Current Storage

Tauri Desktop: ~/.atm/uploads/ (local filesystem)
Web Deployment: No server-side file storage yet (localStorage only for metadata)

Proposed Solution

Phase 1: Storage Selection & Display (Immediate)

Objective: Show users where their files are stored and let them choose provider

UI Components:

Settings → Storage Configuration page
- Display current storage location
- Show usage statistics
- Provider selection dropdown
Upload Feedback
- Show destination after upload
- Display file size and location

Phase 2: Cloud Storage Integration (v0.3.0 - High Priority)

Google Drive Integration (Recommended First):

Most users have Google accounts
Generous free tier (15GB)
German privacy compliance (EU servers)
Well-documented API

Features:

Login with Google OAuth
Upload files to Google Drive
Sync with local storage
Choose folders for ATM content

Alternatives:

Dropbox Integration (for users without Google)
Local Storage Only (always available for privacy)

Phase 3: Admin Content on S3 (Advanced - v0.4.0 - Future)

Use Cases:

Pre-loaded Feldenkrais lessons
Training materials
System documentation
User guides

Implementation:

S3 bucket for system content
Read-only access for users
Admin-managed updates

Technical Considerations

Storage Adapter Pattern

interface StorageAdapter {
  upload(file: File): Promise<string>  // Returns file ID/URL
  download(id: string): Promise<Blob>
  delete(id: string): Promise<void>
  listFiles(folder?: string): Promise<FileInfo[]>
}

class LocalStorageAdapter implements StorageAdapter { ... }
class GoogleDriveAdapter implements StorageAdapter { ... }
class DropboxAdapter implements StorageAdapter { ... }

Database Schema Update

ALTER TABLE lessons ADD COLUMN storage_provider TEXT DEFAULT 'local';
ALTER TABLE lessons ADD COLUMN storage_file_id TEXT;
ALTER TABLE lessons ADD COLUMN local_file_path TEXT;
ALTER TABLE lessons ADD COLUMN storage_uri TEXT;

User controls their data
Option to export all data
Option to delete all data
Clear data processing policy
End-to-end encryption option

Acceptance Criteria

Phase 1 (Immediate)

Create storage settings page
Display current storage location
Show storage usage statistics
Add file metadata to uploads

Phase 2 (v0.3.0 - High Priority)

Google Drive API integration (OAuth)
File upload to Google Drive
File download from Google Drive
Storage provider selection in settings

Phase 3 (v0.4.0 - Future)

S3 integration for admin content
Pre-loaded lessons from S3
Admin content management interface

Questions for Product Decision

Should we implement OAuth for cloud providers?
Should users be able to use multiple cloud providers?
Should files be synced automatically or on-demand?
Should we track storage costs/quota usage?
How to handle file versioning in cloud storage?
What's our policy on data retention and deletion?
