Effective date: August 5, 2026
EchoVault ("the App") is built on one simple promise: your recordings never leave your device. This policy explains, in plain language, exactly what that means.
The App has no accounts, no servers, no analytics SDKs, no advertising SDKs and no tracking of any kind. Specifically, the App never collects, transmits or stores remotely:
The developer never sees, receives or has access to any content you record.
All data stays in the App's private sandbox on your iPhone:
| Data | Where it lives | Who can access it |
|---|---|---|
| Recordings (audio files) | App sandbox | Only the App (and you, via export) |
| Transcriptions & minutes | App sandbox | Only the App |
| AI/speech models | App sandbox | Only the App |
| Purchase status | Apple App Store + App sandbox | You and Apple |
Deleting the App permanently deletes all of this data. You can also delete individual recordings at any time in Settings → Recordings.
The App accesses the internet for exactly two purposes, both initiated by you:
official public repositories (Hugging Face and GitHub). These requests transmit no personal data and no content of yours — they are ordinary file downloads.
Apple through StoreKit. We never receive your payment details.
Nothing else in the App requires or performs any network communication. All recording, transcription, summarization, search and AI chat run 100% on-device, and work in Airplane Mode.
If you enable iCloud Backup in Settings, the App copies your recordings and transcripts to your own iCloud account using Apple's CloudKit/Documents infrastructure, so you can restore them after reinstalling. This transfer is encrypted by Apple and is accessible only with your Apple ID. Backup is off by default and can be disabled or erased at any time. The developer has no access to your iCloud content.
The App requests microphone access solely to record audio locally. The microphone permission string states this explicitly. No audio is ever streamed or uploaded.
The App does not collect any data from anyone, including children under 13.
The App ships open-source inference runtimes (sherpa-onnx, llama.cpp) and model files published by their respective authors. These run entirely on your device and transmit no data. Model files are downloaded from the official repositories named in Section 3.
Because we hold no personal data, there is nothing to access, correct or delete on our side — your data is always in your hands: export it, delete it, or delete the App.
If this policy changes materially, the update will ship with a new App version and an updated effective date. Continued use after an update constitutes acceptance.
