About

Arca: Speech to Text - Private Audio Transcription Arca is a professional-grade transcription tool running entirely on your iPhone. No internet required. No data leaves your hardware. Ever. In a world where voice apps upload your conversations to cloud servers, Arca keeps everything on-device. Your audio is transcribed locally and protected by Apple’s Secure Enclave — built for journalists, lawyers, researchers, and anyone who demands total privacy. THE ON-DEVICE GUARANTEE • 100% Local Processing: Every word is transcribed directly on your device using local neural models. Nothing is uploaded, tracked, or shared. • Zero Cloud Storage: Your audio files are never sent to external servers, never stored in the cloud, and never used to train AI models. • Complete Hardware Security: All transcripts and recordings remain on your physical device, protected by on-device encryption. BUILT FOR PROFESSIONALS • Speaker Recognition: Automatically separate and identify different speakers in meetings, interviews, and panel discussions. • Import Any Audio File: Easily transcribe pre-recorded voice memos, interviews, and meetings in M4A, WAV, or MP3 formats. • Real-Time Transcription: Instant, high-accuracy speech-to-text with zero lag and no connection required. • Works 100% Offline: Transcribe anywhere — soundproof offices, remote locations, or in airplane mode. • Professional Export: Turn transcripts into clean, formatted PDF or TXT documents with one tap. • Privacy Compliance: Engineered with technical safeguards to support strict confidentiality, KVKK, and GDPR requirements. ZERO FRICTION • No Account Required: Open the app and begin immediately. No email, sign-up, or personal details collected. • Arca Plus: Unlimited transcription for high-volume workflows. One subscription, zero usage caps. • Seamless Restore: Subscriptions link directly to your Apple ID for instant device switching and restore.
