• ✅ Settings and preferences
• ✅ Equipment maintenance tracking
• ✅ Connection history

What Doesn't Sync

• ❌ Apple Health data (device-specific)
• ❌ Active Bluetooth connections
• ❌ Temporary cache

Why Use iCloud Sync?

Benefits

• Never lose workout data
• Survive app reinstalls
• Recover from device failure

Multi-Device Sync:

• Use app on iPad and iPhone
• Data seamlessly syncs between devices
• Always up-to-date everywhere

No Extra Account:

• Uses your existing Apple ID
• No third-party services
• No additional sign-up

Enabling iCloud Sync

Prerequisites

• Signed into iCloud on your iPhone
• iCloud Drive enabled (Settings > [Your Name] > iCloud > iCloud Drive)
• Sufficient iCloud storage space (usually <5 MB needed)

Enable Sync

1. Go to Settings > iCloud Sync
2. Toggle Enable iCloud Sync ON
3. App begins first sync automatically

First Sync

On first enable:

• All local data uploads to iCloud
• Takes 5-30 seconds depending on data amount
• "Last Synced" timestamp updates when complete
• Status indicator shows sync progress

How Syncing Works

Automatic Syncing

With iCloud enabled:

• App launches: Syncs on startup
• Data changes: Syncs after workouts, program edits, etc.
• Periodic: Syncs every few minutes in background
• Seamless: Happens automatically, no action needed

Manual Syncing

To force an immediate sync:

1. Go to Settings > iCloud Sync
2. Tap Sync Now button
3. Wait for "Last Synced" to update

Sync Status

Last Synced Timestamp

Shows when last successful sync occurred:

• "Just now" - Synced in last minute
• "X minutes ago" - Recent sync
• "X hours ago" - May want to force sync
• "Never" - Hasn't synced yet or error occurred

Sync Indicator

When syncing:

• Loading spinner appears
• Status shows "Syncing..."
• Completes in a few seconds

Syncing Across Devices

Setting Up Multiple Devices

On Device 1 (original device):

1. Enable iCloud Sync
2. Data uploads to iCloud

On Device 2 (new device):

1. Sign in with same Apple ID
2. Install Treadmill Assistant
3. Enable iCloud Sync
4. Data downloads from iCloud automatically

How It Works

• First device to sync: Uploads local data
• Subsequent devices: Download cloud data
• Ongoing: Changes sync bidirectionally
• Conflicts: Newer data wins (by timestamp)

Conflict Resolution

If same workout edited on two devices:

• Most recent change is kept
• Older change is discarded
• Automatic and seamless

Privacy and Security

Where Data is Stored

• Your personal iCloud Drive account
• Folder: Treadmill Assistant (may be hidden)
• Only you have access
• Protected by Apple ID password/2FA

What's NOT Sent to Third Parties

Anything - we don't process your data at all.

• ✅ Data stays in your iCloud
• ✅ No external servers
• ✅ No company access to your data
• ✅ Fully private

Encryption

• Data encrypted in transit (HTTPS)
• Data encrypted at rest (iCloud standard encryption)
• Protected by Apple's security

Managing iCloud Storage

How Much Space Needed?

Typical usage:

• Empty app: <1 MB
• 100 workouts: ~2 MB
• 1000 workouts: ~10-15 MB
• Programs/settings: <1 MB

Very minimal - won't significantly impact iCloud storage.

Checking iCloud Storage

1. Open iOS Settings
2. Tap [Your Name]
3. Tap iCloud
4. View storage breakdown

Treadmill Assistant appears under "Other Apps".

If Storage Full

If iCloud storage is full:

• Sync will fail
• App notifies you
• Upgrade iCloud plan or free up space
• App continues working locally

Disabling iCloud Sync

Turn Off Sync

1. Go to Settings > iCloud Sync
2. Toggle Enable iCloud Sync OFF
3. Choose what happens to cloud data:
   • Keep in iCloud - Preserve backup
   • Delete from iCloud - Remove cloud data

After Disabling

• Local data remains on device
• Cloud data kept or deleted based on choice
• Other devices with sync enabled unaffected
• Can re-enable anytime

Re-Enabling Sync

If you disable then re-enable:

Scenario 1: Cloud Data Exists

• App downloads cloud data
• Merges with local data
• Newer data wins

Scenario 2: Cloud Data Deleted

• App uploads current local data
• Creates new cloud backup
• Other devices sync to this data

Troubleshooting iCloud Sync

"Not Signed Into iCloud"

Problem: App says not signed into iCloud

Solution:

1. Open iOS Settings
2. Tap Sign in to your iPhone at top
3. Sign in with Apple ID
4. Return to app and enable sync

Problem: iCloud Drive is turned off

Solution:

1. iOS Settings > [Your Name] > iCloud
2. Toggle iCloud Drive ON
3. Return to app and enable sync

Sync Never Completes

Problem: "Syncing..." never finishes

Solutions:

• Check internet connection (sync needs network)
• Check iCloud storage not full
• Force quit and reopen app
• Disable/re-enable iCloud Sync

Last Synced Shows Old Timestamp

Problem: "Last Synced" is hours or days old

Solutions:

• Tap Sync Now to force sync
• Check internet connection
• Verify iCloud is working (test with other apps)
• Restart iPhone

Data Not Syncing to Second Device

Problem: Changes on Device 1 don't appear on Device 2

Solutions:

• Verify both devices signed into same Apple ID
• Check iCloud Sync enabled on both devices
• Force sync on Device 1 (Sync Now)
• Open app on Device 2 (triggers download)
• Wait a few minutes for propagation

iCloud Storage Full Error

Problem: "iCloud storage full" message

Solutions:

• Free up iCloud space (delete photos, backups, etc.)
• Upgrade iCloud plan (Settings > [Your Name] > iCloud > Manage Storage)
• App continues working locally without sync

iCloud vs Apple Health

These are separate:

iCloud Sync (Treadmill Assistant)

• Backs up app data
• Syncs across devices
• Managed by this app

Apple Health

• Device-specific workout storage
• Does NOT sync via iCloud (Apple's limitation)
• Each device has separate Health database

Both can be used together for comprehensive backup.

Best Practices

Recommendations

1. Enable iCloud Sync - Free backup, why not?
2. Check sync status occasionally
3. Don't disable unless needed - Automatic protection
4. Use multiple devices - Seamless experience

What to Avoid

• ❌ Don't disable/re-enable frequently (can cause conflicts)
• ❌ Don't delete iCloud data unless certain
• ❌ Don't sign out of iCloud without backing up data first
