CallVault

CallVault is a non-root, FOSS call recorder for Android that records both sides of a phone call. It drives a privileged shell session entirely on-device — no root, no Shizuku, no companion PC — using an embedded ADB client (libadb-android) over Android's own Wireless Debugging. Audio is captured through a direct on-device path, with scrcpy-server as an automatic fallback.

Features 🎙️ Records both sides of incoming & outgoing calls (incl. Bluetooth / headset) 💬 Recording app calls — VoIP (opt-in, experimental) — records calls made inside WhatsApp, Signal and Telegram, both sides, with the calling app's icon on each recording (off by default; not carrier Wi-Fi calling) 📶 Offline recording (opt-in) — record calls even with no Wi-Fi network, for calls on the road (off by default; opens a local, RSA-gated debugging port when enabled) 🔓 Keeps recording when the screen locks — on many phones that otherwise stop a recording mid-call, fixed from inside the app in one tap 🛡️ Resilient recording (opt-in) — makes recording resistant to interruptions: a recording already in progress is unaffected if Android stops the background helper mid-call (off by default) 🤖 Automatic recording with per-call rules — ignore anonymous, cross-country, or specific contacts 🎚️ Record only what you want — carrier calls and app (VoIP) calls are switched independently, so CallVault can record both, either, or app calls only ☁️ Save to device, a cloud folder, or both, with optional scheduled sync (immediate / daily / weekly) 🧹 Retention / auto-delete — remove recordings after a chosen age, separately for device & cloud, swept daily at a time you pick (your local time zone) ▶️ In-app recordings list with playback, contact-name resolution, source badges, and filters 🗂️ Filter recordings by source, direction, contact, or date; play & delete each copy individually 🎚️ Opus or AAC at your chosen bitrate; BCR-compatible file names 🔒 No root, no Shizuku, no PC — everything runs on-device; Wireless Debugging is set up automatically and stays on while CallVault is ready (why) ⬆️ In-app updates — CallVault notices new GitHub releases and installs them on a tap (signature-pinned, resumable download); never auto-installs 🎨 Clean, modern UI — no telemetry, no ads, no nonsense
