Frequently asked questions
Why does DjinnScan need the camera permission?
The Pro Camera and the SLS visual mode use the rear camera to display a live cinematic HUD (frame, grid, overlays). Nothing is recorded without an explicit tap on the capture button. You can revoke access anytime in your device Settings; the rest of the app keeps working.
Why does DjinnScan need the microphone permission?
The EMF radar and the ambient meter continuously read the ambient sound LEVEL (dB) — no audio is recorded. Audio is only captured while you explicitly hold the EVP button or start a voice K-II question. Recordings are processed on-device and, if you request transcription, sent temporarily to our backend and OpenAI Whisper, then deleted.
How does the EMF / sensor detection actually work?
The scanner reads your device's native magnetometer (µT) and accelerometer. Variations from an adaptive baseline drive the on-screen gauge. DjinnScan uses REAL physical readings — there is no fake random generator — but the paranormal interpretation is provided purely for entertainment.
How do EVP recordings work?
Hold the EVP button, speak or leave silence, then release. The audio is saved locally in your Investigation Journal. Premium users can request a transcription: the audio is sent securely to our backend and forwarded to OpenAI Whisper for text output, then deleted from our servers.
How does the Spirit Box work?
The Spirit Box simulates a frequency sweep and speaks context-aware words in your selected language (French, English, Spanish, Arabic) using text-to-speech. Premium users can enable higher-quality ElevenLabs voices. No microphone recording is required to use the Spirit Box.
How do I restore my Premium purchases on a new device?
Open DjinnScan → Settings → Restore purchases. On iOS you must be signed in with the Apple ID that made the original purchase; on Android with the same Google account. Restoration is handled by Apple / Google and by RevenueCat — DjinnScan never sees your payment details.
How do I manage or cancel my Premium subscription?
Subscriptions are managed by the store, not by DjinnScan.
• iOS: Settings → Apple ID → Subscriptions → DjinnScan.
• Android: Play Store → Profile → Payments & subscriptions → Subscriptions → DjinnScan.
Cancel at least 24h before the renewal date to avoid the next charge.
Is DjinnScan suitable for children?
DjinnScan is intended for users aged 13 and older. Some visual and audio effects can be anxiety-inducing. A disclaimer and a health & safety guide are shown inside the app.
The app crashes or a feature is broken — what should I do?
Please email contact@djinnscan.com with your device model, OS version, app version (shown in Settings), and a short description or screenshot. We reply within 48 hours on business days.
DjinnScan is intended for entertainment and environmental investigation only. It makes no claim to prove, detect or diagnose any paranormal, spiritual, medical, safety or religious matter. Interpretations shown on screen are ludic.
