Sign-In Methods

DevLingo uses a passwordless authentication design and offers two sign-in methods:

Apple Sign In (macOS App)

On first launch of the macOS app, click the Apple Sign In button. The system will verify your identity using your Apple ID. This is the fastest and most secure method — no password to remember.

Magic Link (Email)

Select Magic Link and enter your email address. We’ll send you an email with a login link. Click the link to sign in — no password needed, a completely passwordless experience.

Note

Passwordless authentication improves security while simplifying the sign-in process. Your account data is protected by JWT tokens.

Managing Your Subscription

In-App Management

1. Open DevLingo
2. Click the DevLingo icon in the menu bar
3. Select Settings > Subscription
4. View your current plan, renewal date, and usage statistics

Upgrading or Downgrading

In the subscription settings, click Upgrade or Change Plan. Upgrades take effect immediately; downgrades take effect at the end of the current billing period.

Online Management (License Key Users)

Users who purchased via the web with a License Key can manage their subscription at dashboard.devglish.com.

Data Export

Exporting the Word Book

1. Open Settings > Data > Export
2. Select CSV format
3. The file includes all saved entries, definitions, examples, and learning progress

Tip

Regular exports serve as data backups. Anki and Notion integrations are on the roadmap.

Account Deletion

To delete your account:

1. Go to Settings > Account > Delete Account
2. Enter your email address to confirm
3. After deletion, all data is permanently removed (including Word Book, learning history, and sync data)

Note

Account deletion is permanent and cannot be undone.

Device Management

Multi-Device Sign-In

Sign in on multiple Mac devices using the same Apple ID or email. The Word Book and learning progress automatically sync across all devices.

License Key Users

License Keys are bound to your account (not to a device), so you can sign in on any Mac to restore your license. The system performs a daily online verification.

Daily Sync

Cloud sync uses a last-write-wins strategy: the most recently modified version takes priority. Offline edits are automatically merged when the network is restored.

Access Permissions and Privacy

DevLingo requires the following permissions:

• Accessibility permission: For the global hotkey (⌘⇧D) and cross-app text selection
• Network connection: For AI lookups, cloud sync, and pronunciation synthesis
• Microphone (optional): Only needed if you want to record your own pronunciation
