The DTMF.io Android app does not depend on Google Play Services. It requires network access, vibration and sleep prevention permission (the latter used only during calls). It also requests, but does not require, camera access (for scanning a QR code to log in), microphone access (for calls), and contacts access (for displaying contact names only — we don't transmit any of your contact data to our servers).
