LinkUp: Connect, Share, and Stay Together

LinkUp is a high-performance communication hub designed for the modern world. It combines seamless instant messaging and VoIP calling with high-precision, real-time location sharing. Whether you’re coordinating a meetup or making sure a loved one gets home safely, LinkUp helps you stay synced with clarity and control.

🛡️ PRIVACY BY DESIGN
We take a practical, privacy-minded approach—not empty slogans:
• Delivery-first media pipeline: Photos, videos, voice notes, and files are processed to reach your friends. Temporary cloud copies are removed after delivery where applicable; undelivered items are auto-cleaned on a schedule.
• Account data we need to run the app: Profile details, friend connections, and search index data are retained so you can sign in, find friends, and stay connected—until you delete your account or request further removal.
• Encrypted in transit: Messages, location coordinates, and call signaling are protected with industry-standard HTTPS/TLS. Call audio uses encrypted WebRTC media channels. Chat is delivered through a secure cloud relay (not marketed as end-to-end encrypted chat).
• Verified Google Sign-In: Sign in with Google to create your account and reduce spam accounts.
• In-app control: Manage sounds, Do Not Disturb for calls or location requests, permissions setup, unfriend, and account deletion from Settings. Contact support if you need additional data removal.

💬 ADVANCED COMMUNICATION
Stay in touch with tools built for speed and clarity:
• Instant messaging with a real-time backend for smooth conversations
• High-fidelity VoIP voice calls that can keep working while you multitask
• Multimedia sharing for photos, videos, and audio
• Document sharing for PDFs and common office files
• Link previews so shared URLs show a useful title/image card
• Professional voice notes with a clean playback experience

👥 FRIENDS & DISCOVERY
• Smart friend search: find people by the email name before @ (results show name and photo—not the full email)
• Add friends for chat, calls, and location features in one place
• Unfriend anytime to end messaging, calls, and location sharing with that person

📍 REAL-TIME LOCATION SHARING
Move together, even when you’re apart:
• Live map sharing during accepted tracking sessions
• Custom proximity alarms when a friend enters your nearby zone
• Background-aware location so tracking can continue when the app isn’t open
• Request-based sharing: friends request access; you accept or decline
• Do Not Disturb for location requests when you don’t want to be asked

⚙️ SETTINGS THAT ACTUALLY HELP
• Clear permissions and battery setup guidance so alerts, calls, and location work reliably
• Custom ringtones/alarms for calls, location requests, and nearby alerts
• Do Not Disturb for calls and location
• Account tools including logout and in-app account deletion

⚡ CORE FOREGROUND SERVICE USAGE
LinkUp uses foreground services to keep essential features reliable:
• Real-time proximity / tracking: a foreground location service helps proximity and live tracking work even if the screen is off or you’re in another app—more reliable than basic background updates alone.
• Uninterrupted voice calling: microphone and phone-call type foreground services help prevent the system from ending your call when you leave the call screen.

A persistent notification is shown while these services are active for transparency and control.

🚀 WHY LINKUP?
LinkUp combines the social features you need—chat, calls, and live location—with honest privacy controls and a setup flow designed for real Android devices.
