Privacy policy

The Диктофон (Voice Recorder) application - Last updated: 12 July 2026 - Canonical address: voice.krut.top/privacy

Who we are

Диктофон (Voice Recorder) is a mobile application for recording and transcribing voice notes. The copyright holder of the application and the personal data operator is an individual entrepreneur; the details are set out at the bottom of the page.

What data is processed

1. Audio recordings

The voice recordings you make in the application are stored in the application's private sandbox on your device (<sandbox>/recordings/*.m4a). Only the application itself has access to this folder. The recordings are not sent to our servers.

2. Recording metadata

The name, duration, creation date, tags, the "favorite" flag, the transcript text, notes, bookmarks and the list of birds found are stored in AsyncStorage locally. By default they do not leave the device - except where you yourself enable backup to Yandex.Disk (see below).

Transfer of data to third parties

Speech recognition is performed entirely on the device - your audio is not sent anywhere. Data is transferred in the cases listed below.

Backup to Yandex.Disk (optional)

Local transcription with GigaAM (default)

By default transcription is performed entirely on the device by the GigaAM model (Sber) via sherpa-onnx. No network requests carrying your audio take place.

Google Perch bird recognition (on the device)

Bird recognition by call is performed on the device by the Google Perch model. The audio is not sent anywhere. The "photo / description" buttons next to an identified bird open an external web search (Google Images / Wikipedia) containing only the species name (without your audio).

Text improvement with the SAGE neural network (on the device)

Correction of mistakes and punctuation in the transcript (using the "improve text" button) is performed on the device by the SAGE neural network model. The transcript text is not sent anywhere.

Downloading ML models

On first use the application downloads the model files (GigaAM, Perch, SAGE) from Hugging Face. Only the network request itself is made (your IP is visible to the hosting provider); recordings and personal data are not sent.

License / trial period server (voice.krut.top/api)

Purchases via RuStore

Service notifications (voice.krut.top/popup)

Occasionally (no more than once every 3 hours) the application requests service notifications from our server - for example, about new versions or important changes. What is transferred: only the network request itself (your IP is visible to the server); device identifiers, recordings, transcripts and personal data are not transferred.

Crash reports (Sentry)

Android permissions

PermissionWhy it is needed
RECORD_AUDIORecording from the microphone - the core function.
VIBRATEHaptic feedback on taps.
INTERNETDownloading speech models from Hugging Face; checking the license / trial period at voice.krut.top/api (only the hashed installation identifier is transmitted); at your choice - backup to Yandex.Disk.
FOREGROUND_SERVICE + FOREGROUND_SERVICE_MICROPHONERecording is not interrupted when the screen is off.
POST_NOTIFICATIONSA notification about the current recording in the notification shade.

The application does not ask you for any other permissions requiring confirmation (apart from those listed above - the microphone and notifications). The build may include service permissions of the "normal" category, which Android grants automatically, without a dialog, and which do not give access to your personal data: access to the network and Wi-Fi state, sound settings, media playback in the notification, biometrics for protected local storage and file access on legacy versions of Android. These permissions are not used to collect or transfer your data.

Analytics, advertising, trackers

The application does not contain any usage analytics, any advertising or any third-party tracker SDKs. The only thing enabled is the collection of crash reports via Sentry (see the "Transfer of data to third parties" section above) - without personal data and without tracking; the contents of your recordings are not transmitted.

Retention period

Recordings and metadata are stored locally until you delete them yourself or delete the application itself. Removing the application from the device also deletes all the recordings (Android sandbox).

Children

The application is not directed to children under 13 years of age.
