iCloud	iOS-only users	Zero config, native integration, Apple ecosystem
Supabase	Cross-platform without NAS	Generous free tier, easy setup, hosted
WebDAV	NAS users	Local data, Synology/Nextcloud/etc.
S3 protocol	Flexible cloud storage	Cloudflare R2/AWS S3/MinIO, large free tier

🆕 BeeCount Cloud (Self-hosted Sync + Web)

Sub-second multi-device sync + Web admin + multi-user isolation. Recommended for users with NAS / VPS / Docker.

One-click Deploy

# docker-compose.yml
services:
  beecount-cloud:
    image: sunxiao0721/beecount-cloud:latest
    restart: unless-stopped
    ports:
      - "8869:8080"
    volumes:
      - ./data:/data

docker compose up -d
docker compose logs beecount-cloud | grep -A 10 "first launch"

Output similar to:

 BeeCount Cloud — first launch, admin account auto-created:

   Email:    owner@example.com
   Password: FIDodUnwprkw1zUi

With this account:

Open http://<server-ip>:8869 in browser → Web admin console
In the App, choose "BeeCount Cloud", enter server URL + credentials

Add Family / Teammates

Web console → "Users" → "Add User" with their email and password → tell them to log in. Each user's data is isolated.

Advanced Configuration

services:
  beecount-cloud:
    image: sunxiao0721/beecount-cloud:latest
    restart: unless-stopped
    ports:
      - "8869:8080"
    environment:
      # Override default random admin:
      BOOTSTRAP_ADMIN_EMAIL: me@example.com
      BOOTSTRAP_ADMIN_PASSWORD: <strong password>
      # Override JWT secret (default: auto-generated to /data/.jwt_secret):
      # JWT_SECRET: <32+ byte random string>
    volumes:
      - ./data:/data

Tips

PWA support: Web admin is a PWA — install icon appears in the address bar to install as a desktop app
Data location: SQLite + attachments + JWT secret all live in ./data/. Migrate / back up the whole directory.
Public deployment: Front with nginx / caddy for HTTPS + domain.

Option 2: iCloud (Recommended for iOS)

Best for: iOS users wanting zero-config, seamless sync.

Pros:

✅ Zero config: works out of the box
✅ Native: auto-sync via Apple ID
✅ Privacy: data in your iCloud Drive
✅ Multi-device: iPhone + iPad auto-sync

Setup:

Sign in to iCloud and enable iCloud Drive on the device
Open BeeCount → Profile → Cloud Service
Choose iCloud

💡 iCloud only works between iOS devices. For iOS + Android, use Supabase / S3 / BeeCount Cloud.

Option 3: Supabase (Beginner-friendly)

Best for: Users without NAS who want quick setup.

Setup:

Create Supabase project
- Sign up at supabase.com
- Create a new project; pick a region
- Get URL and anon key from project settings
Configure Storage
- Create a bucket named beecount-backups
- Set it to Private (don't check Public bucket)
- Configure RLS policies: Create 4 policies so users can only access their own data
  - Go to bucket Policies tab
  - Create the following 4 policies (same configuration each):
    - SELECT: read own backup files
    - INSERT: create new backups
    - UPDATE: update own backups
    - DELETE: delete own backups
  - Each policy:
    - Policy name: customizable (e.g. Allow user access to own backups)
    - Target roles: authenticated
    - Policy definition:
```
((bucket_id = 'beecount-backups'::text) AND ((storage.foldername(name))[1] = 'users'::text) AND ((storage.foldername(name))[2] = (auth.uid())::text))
```
    - This ensures users only access beecount-backups/users/<their-user-id>/.
Configure in app
- Open BeeCount → Profile → Cloud Service
- Tap "Add custom cloud service"
- Service type: Supabase
- Enter your URL and anon key
- Save and enable
- Tap "Sign in", register or log in to start syncing

Option 4: WebDAV (Recommended for NAS Users)

Best for: Users with NAS or private cloud storage.

Supported services:

✅ UGREEN NAS
✅ Synology NAS
✅ Nextcloud
✅ Jianguoyun WebDAV
✅ ownCloud
✅ Other WebDAV-compatible servers

Setup:

Enable WebDAV
- Enable WebDAV on your NAS or cloud platform
- Note the server URL (e.g. http://nas.local:5005)
- Create or use an existing user account
Prepare directory (optional)
- Create BeeCount folder under WebDAV root, or use any path
Configure in app
- Open BeeCount → Profile → Cloud Service
- Tap "Add custom cloud service"
- Service type: WebDAV
- Fill in:
  - WebDAV server URL: e.g. http://nas.local:5005
  - Username / Password
  - Remote path: e.g. /home/BeeCount or /BeeCount
- Tap "Test connection" to verify
- Save and enable. WebDAV doesn't need login — sync starts after configuration.

Common WebDAV examples:

UGREEN NAS:
- URL: http://your-nas:5005
- Remote path: /home/BeeCount

Synology NAS:
- URL: http://your-nas:5005 or https://your-domain
- Remote path: /BeeCount

Jianguoyun:
- URL: https://dav.jianguoyun.com/dav/
- Remote path: /BeeCount

Option 5: S3 Protocol (Recommended for Flexibility)

Best for: Users who want flexible cloud providers or generous free tiers.

Supported services:

✅ Cloudflare R2 (recommended, 10GB free)
✅ AWS S3
✅ MinIO (self-hosted)

- Open R2
- Create a bucket like beecount-backups
- Note the bucket name
Get API credentials
- Click Manage R2 API Tokens
- Create a new API Token
- Permission: Object Read & Write
- Note:
  - Access Key ID
  - Secret Access Key
  - Endpoint (like <account-id>.r2.cloudflarestorage.com)
Configure in app
- Open BeeCount → Profile → Cloud Service
- Tap "Add custom cloud service"
- Service type: S3 Protocol
- Fill in:
  - Endpoint: R2 endpoint (no https://)
  - Region: auto
  - Access Key / Secret Key
  - Bucket name: e.g. beecount-backups
  - Use HTTPS: enable (recommended)
  - Port: leave blank
- Tap "Test connection" to verify
- Save and enable

Other S3 examples:

Cloudflare R2:
- Endpoint: <account-id>.r2.cloudflarestorage.com
- Region: auto
- Use HTTPS: yes

AWS S3:
- Endpoint: s3.amazonaws.com
- Region: us-east-1 (use your bucket's region)
- Use HTTPS: yes

MinIO (self-hosted):

- Region: us-east-1 or auto
- Use HTTPS: based on your config
- Port: 9000 (or your custom)

💡 Tips:

Don't include http:// or https:// in the endpoint

FAQ

Q: Which option should I pick?

iOS single device → iCloud
Multi-device real-time + self-host → BeeCount Cloud
Cross-platform without NAS → Supabase or S3
Have a NAS → WebDAV

Q: WebDAV upload failing?

Check WebDAV is enabled and port is correct
Verify username and password
Some NAS WebDAV needs specific paths (e.g. UGREEN needs /home/)
Tap "Test connection" for detailed errors

Q: S3 connection failing?

Endpoint must not include http:// or https://
Verify Access Key and Secret Key
Verify bucket name spelling
Check bucket region matches (AWS S3 needs exact, R2 uses auto)

Q: How to sync between devices?

iCloud: log into the same Apple ID
BeeCount Cloud: same server URL + same account
Supabase: same URL and anon key, same account
WebDAV: same server URL and credentials
S3: same endpoint, Access Key, and bucket
