Privacy Policy

Last updated: October 20, 2026

Vocello is a local, on-device voice studio for Apple Silicon. It is built so your work stays on your device. Vocello does not collect, track, or sell your personal data, and your work never leaves your device.

What Vocello does not do

• No account, sign-in, or user profile.
• No analytics, telemetry, advertising, or third-party tracking SDKs in the app.
• No selling or sharing of any data, because none is collected.
• No transmission of your scripts, recordings, transcripts, or generated audio off your device.

Data stored on your device

Everything you create lives in local app storage on your device: typed scripts, generated audio clips, recorded reference clips, their transcripts, your generation history, and any voices you save. Vocello does not upload any of it. On iPhone, your own device backups (iCloud Backup, or a backup to your computer if you use one) include your generated audio, saved voices and history; downloaded models and caches are excluded. Use Vocello's deletion controls when you want to remove individual items or downloaded models. On macOS, deleting the app itself does not remove its Application Support data.

Microphone

Vocello asks for microphone access only when you choose to record a reference clip for Voice Cloning. Recordings are saved locally and used only for the voice you are creating. They are not uploaded.

Speech recognition (transcription)

When you record a reference clip, Vocello can transcribe it to improve clone quality. Transcription runs on your device using Apple's on-device speech recognition. The audio is processed locally and is not sent to a server by Vocello.

Network use

Vocello's own network activity is downloading AI voice model files from Hugging Face, and only when you install a model. These are ordinary anonymous file downloads over HTTPS: Vocello sends no account, identifier, script, recording, or generated audio, and receives nothing back except the model files. As with any web server, Hugging Face receives your IP address and standard request details, which it handles under its own privacy policy; Vocello does not receive or keep them. On iPhone, the optional export purchase and Restore Purchases go through Apple's App Store. Voice generation itself runs entirely on your device after the model is installed.

On a Mac, Vocello asks on its second launch whether to check for updates automatically, and you can change this at any time in Settings > Updates or check by hand from the Vocello menu. A check downloads a small signed list of releases from GitHub, at most once a day when automatic checks are on, and an update you choose to install is downloaded from GitHub. These requests send no account, identifier, script, recording, or generated audio, and no profile of your Mac. As with any web server, GitHub receives your IP address and standard request details, including the app's version, which it handles under its own privacy statement; Vocello does not receive or keep them.

Optional export

You may optionally choose a Files or iCloud Drive folder so that each new generated clip is also copied there. This is entirely under your control and uses only the folder you pick. Generated clips are always also kept in the app for History.

Deleting your data

• Delete individual generations, or clear all history, from the History screen.
• Delete saved voices from the Voices library.
• Delete downloaded models from Settings.
• On macOS, deleting the Vocello app does not delete its models, voices, outputs, history, or diagnostics from ~/Library/Application Support/QwenVoice. Remove that folder separately only after exporting anything you want to keep.
• On iPhone, use Vocello's visible deletion controls to remove models, saved voices, generated audio, and history before uninstalling when you need an explicit deletion workflow.

This website

This site (vocello.vercel.app) is hosted on Vercel and uses Vercel Web Analytics, a cookieless, aggregate count of page visits. It sets no cookies, stores no identifiers on your device, and does not follow you across sites. The apps themselves contain no analytics of any kind.

Children

Vocello does not knowingly collect personal information from anyone, including children. Because Vocello collects no data, there is nothing for it to gather.

Changes to this policy

If this policy changes, the updated version will be posted on this page with a new date.
