Murder Files
What we collect, and what we never do
Summary
- No account, no name, no email is required to play. The App identifies your installation with a random identifier that we cannot link to you.
- Your voice is recorded only while you hold the microphone button, is converted to text so the suspect can answer, and is not stored by us.
- We do not sell personal data, we do not show advertising, and we do not use your data to train AI models.
Data we process
| Data | Why | Where it goes |
|---|---|---|
| Voice audio (while the mic button is held) | Transcribed to text so the suspect can reply | Sent through our server to OpenAI for transcription; not stored by us, not kept by OpenAI beyond processing under their API terms |
| Your questions and the suspects' replies (text) | Running the interrogation, keeping the conversation in context | Processed by OpenAI through our server; the transcript of a case is saved on your device so you can continue later |
| Suspect reply text | Turned into speech | Sent to ElevenLabs for speech synthesis; not stored by us |
| Anonymous installation ID, device model, iOS version, app language | Usage statistics, crash and error tracking, keeping progress statistics | Google Firebase (Analytics and Firestore) |
| Gameplay events (cases opened and closed, stars, tutorial steps, paywall views, purchases completed) | Understanding which cases work and which do not | Google Firebase, keyed by the anonymous installation ID |
| Purchase status (which products you own, subscription state) | Unlocking what you bought, restoring purchases | Apple App Store and RevenueCat, keyed by an anonymous app user ID. We never see your payment details. |
| Case feedback and reply reports you choose to send | Improving the cases and the AI suspects | Google Firebase, together with the text of the reported reply and the case number |
We do not collect your name, email address, contacts, photos, precise location or advertising identifiers. The App does not use third-party advertising or tracking SDKs, and it does not request App Tracking Transparency permission because it does not track you across apps or websites.
Voice and AI, in detail
Interrogations are played by a language model. When you hold the microphone, the App streams audio to our own server, which forwards it to OpenAI for speech-to-text and for generating the suspect's reply. If the connection to OpenAI fails, the App may fall back to Apple's on-device or server-based speech recognition, governed by Apple's privacy policy. The reply text is then sent to ElevenLabs, which returns the suspect's voice. Our server adds no identity information to these requests; the providers receive the audio or text and an anonymous session reference only.
Audio is not retained on our server. Transcripts of your interrogations are stored on your device only, so you can resume a case. If you report a reply, the text of that reply (not audio) is sent to us.
Service providers
- OpenAI (speech-to-text and language model). Privacy policy. API data is not used to train OpenAI models.
- ElevenLabs (text-to-speech). Privacy policy.
- Google Firebase (Analytics, Firestore, Crashlytics-style error reporting). Privacy and security.
- RevenueCat (purchase and subscription management). Privacy policy.
- Apple (App Store purchases, optional speech recognition). Privacy policy.
- Google Cloud Run hosts the server that relays requests to OpenAI and ElevenLabs, located in the European Union.
These providers process data on our behalf under their own terms and may store it in the United States or the European Union. We do not share data with anyone else, except where the law requires it.
Retention and deletion
- Voice audio: not retained.
- Interrogation transcripts and case progress: on your device, until you reset progress in Settings or delete the App.
- Anonymous usage statistics and feedback: kept for up to 26 months, then deleted or aggregated.
- Purchase records: kept for as long as needed to honour your purchases and to meet legal obligations.
To have the anonymous server-side records removed, email support@candevecioglu.com with the Device ID shown in the App's Settings. We cannot identify your records without it.
Your rights
Depending on where you live (including the EU/EEA under the GDPR and Türkiye under KVKK), you may have the right to access, correct, delete or restrict the processing of personal data, and to object or complain to a supervisory authority. Because the App holds no account, most requests are fulfilled by the controls on your device; for anything else, contact us at the address above.
Legal basis: performance of the game you asked for (running interrogations, purchases) and our legitimate interest in keeping the App working and improving it (anonymous statistics). Microphone access always requires your explicit permission in iOS.
Children
Murder Files deals with crime fiction and is rated for ages 12 and up. It is not directed at children under 13, and we do not knowingly collect personal data from them. If you believe a child has provided personal data through the App, contact us and we will delete it.
Changes
We may update this policy as the App evolves. The date at the top shows the current version; material changes will also be announced inside the App.
