How can we help?

Download the LinguaLinQ app from the App Store or Google Play, or visit lingualinq.ai. Tap "Sign Up" and enter your email address. You'll receive a verification code to complete registration. New accounts include free minutes to try the service.

LinguaLinQ supports 51 languages including English, Spanish, French, German, Chinese (Mandarin & Cantonese), Japanese, Korean, Arabic, Hindi, Portuguese, Russian, Italian, and many more. We're constantly adding new languages based on user feedback.

Minutes are used for both Instant Translate and Video Calls. One minute of translation equals one minute deducted from your balance. Minutes never expire, so you can use them whenever you need. Check your balance anytime in the app header.

Tap and hold the microphone button, speak in your language, then release. LinguaLinQ will translate your speech and play it aloud in the target language. The other person can then respond, and their speech will be translated back to you.

Instant Translate requires an internet connection for real-time AI translation. For best results, use WiFi or a strong cellular connection. We're working on offline mode for select language pairs in a future update.

Tap the language selector at the top of the Instant Translate screen. Choose your language on the left and the target language on the right. Tap the swap button (↔) to quickly reverse the language pair.

From the home screen, tap "Video Call" to create a new room. You'll get a unique room code you can share via WhatsApp, SMS, or Email. The other person clicks the link to join — they don't need to download the app!

If someone shared a link with you, simply click it to join. Or tap "Join Room" on the home screen and enter the room code they gave you. Grant camera and microphone permissions when prompted.

During a video call, tap the CC button to enable live subtitles. You'll see what the other person says in their language, with the translation shown below in your language. Subtitles appear in real-time with less than 1 second delay.

We offer three packages: Starter ($5 for 50 minutes), Popular ($10 for 150 minutes — save 33%), and Value ($20 for 350 minutes — save 43%). All minutes never expire. Prices may vary by region.

Go to Settings > Billing or tap your minute balance in the header. Choose a package and complete payment via credit card, Apple Pay, or Google Pay. Minutes are added instantly to your account.

Go to Settings > Billing and scroll to "Promo Code". Enter your code and tap "Apply". If valid, free minutes will be added to your account immediately. Promo codes can only be used once per account.

We offer refunds for unused minutes within 7 days of purchase. Contact support@lingualinq.ai with your account email and purchase details. Refunds are processed within 5-7 business days.

First, check that LinguaLinQ has microphone permission in your device settings. On iPhone: Settings > LinguaLinQ > Microphone. On Android: Settings > Apps > LinguaLinQ > Permissions. If still not working, try closing and reopening the app.

Video quality depends on your internet connection. Try switching from cellular to WiFi, or move closer to your router. Close other apps using bandwidth. If issues persist, try turning off HD video in call settings.

Speak clearly and at a moderate pace for best results. Avoid background noise when possible. For specialized vocabulary (medical, legal, technical), speak in complete sentences for better context. If issues persist, try selecting a regional dialect variant.

Absolutely. LinguaLinQ never records or stores your audio or video. Conversations are processed in real-time and immediately discarded. We don't sell your data to anyone. Read our full Privacy Policy at lingualinq.ai/privacy.

LinguaLinQ is HIPAA-aligned and built for healthcare use around a zero-PHI design — nothing is recorded or retained. For enterprise privacy questions, contact sales@lingualinq.ai.

Go to Settings > Account > Delete Account. You'll be asked to confirm. This action is permanent and will delete all your data, including any remaining minutes. Refunds for unused minutes may be requested before deletion.
