Summary: Vivace has no app account or login. Your music stays in the storage you choose; optional iCloud Backup copies eligible music to your own iCloud account. Usage analytics through TelemetryDeck are off until you agree and include usage events, app and device details, and a pseudonymous identifier. They do not include music files, song titles or playlists. Likes and dislikes can sync through your own iCloud. The free iPhone and iPad app serves Unity ads; the Mac app has no ads. Optional online lyrics send track details to LRCLIB. The sections below explain these services and your controls.
Vivace is published by MW Supply Limited (“we”, “us”). We operate no servers of our own and run no account system. There is no login.
We do not operate an app login or a server that stores your music library. With your permission, we receive usage analytics through TelemetryDeck, including the technical information and pseudonymous identifier described in section 8. Advertising, lyrics, purchases and iCloud involve the services described below. If you contact us for support, we receive your email address and the information you choose to send.
Vivace opens files or folders you choose through Apple’s file picker, or files you share to it. You can copy music into Vivace’s storage or use supported original folders without creating a second audio copy. Linked folders remain in their original location; access may depend on the drive or file provider being available. Opening files stored by a cloud or network provider can involve downloading them through that provider.
Music is read for playback on your device and is not uploaded to us. Optional iCloud Backup is described in section 5. Files you explicitly share or export go to the destination you choose.
All audio decoding — including DSD-to-PCM conversion, the equalizer, and metadata, artwork and lyric extraction — happens locally on your device. No part of your audio is sent off the device for processing.
Vivace uses your own iCloud account for taste-profile synchronization and optional library backup. Data is stored in your personal iCloud under Apple’s Privacy Policy. We do not receive or have access to your private iCloud library.
The free iPhone and iPad app shows a banner on library/browse screens and an occasional full-screen ad when you reopen the app. Full-screen ads are blocked during playback and are not placed over Now Playing. The native Mac app has no ads. Ads are served by Unity Ads under Unity’s Privacy Policy. Unity may process advertising and device identifiers, technical and usage data, and an approximate location inferred from your IP address to serve ads and prevent fraud.
Analytics are off until you agree. Vivace uses TelemetryDeck to understand feature use and reliability. The data includes usage events, such as opening the app, completing an import or using a paid feature; limited event details, such as an audio format or a rounded import-count range; and SDK-supplied information such as app version, device model, operating system, language/region, time zone, display/accessibility settings and session statistics.
Purchase and subscription diagnostics. With analytics enabled, events can include a monthly, yearly, lifetime or theme category; checkout, restore and delayed-delivery outcomes; verified free-trial status; and a coarse membership, renewal or billing-retry state observed when you use Vivace. We use these signals to understand purchase friction and whether Pro features work and are used. They are not complete payment or refund records. Vivace does not send payment details, Apple Account information, receipts or transaction identifiers to TelemetryDeck.
Reliability diagnostics. Events can include plan availability, a plan-loading time range, a limited error category, playback file format and a lyric-lookup outcome. They do not contain raw error messages, lyric text or your music contents. Collection is bounded to avoid repeatedly sending the same failure or state during a session.
The SDK also sends a pseudonymous hashed identifier and a session identifier so usage can be measured across events. These do not contain your name or email address, but they are identifiers; we do not describe this as collecting no data. Vivace does not send music files, song titles, artists, album names, playlist contents or file paths to TelemetryDeck. Vivace does not use these analytics for targeted advertising. TelemetryDeck explains its processing in its privacy policy and identifier documentation.
You can decline without losing playback features, or change your choice in Settings › Privacy › Share Usage Analytics in version 1.0.33 and later. Earlier versions call the same control Share Anonymous Usage Data.
Withdrawal in version 1.0.33 and later: turning the control off disables new SDK events and blocks pending analytics transmissions while it remains off. Requests already transmitted cannot be recalled. Previously collected events may remain in a local SDK cache and may be sent if you enable analytics again. Turning the control off does not erase data already received by TelemetryDeck.
Earlier versions: turning the control off stopped Vivace’s own event calls, but an already-running SDK could still send automatic session events or queued data until the app process ended. After turning it off, fully quit and reopen Vivace to keep the SDK from starting, and update to version 1.0.33 or later for the improved withdrawal behavior.
If you enable online lyrics, Vivace uses LRCLIB to find matching lyrics. Requests include the track title, artist, album and duration; they do not include audio files or a Vivace account identifier. As with any network request, the service receives connection information such as an IP address. Lyrics are cached on your device. Turning off online lookup stops new lookups; embedded and previously cached lyrics remain available.
Vivace Pro is sold through the App Store as an auto-renewing subscription or a one-time purchase. Purchases are processed by Apple; we never see your payment details. Apple may share aggregate, non-identifying sales information with us.
Vivace does not request microphone, contacts, photo-library or location-service access. Unity may infer approximate location from an IP address as described in section 7. On iPhone and iPad, tracking authorization is requested for personalized ads where applicable; you may decline. Apple’s file picker grants access to the files and folders you select, and linked folders may retain that access so they can be reopened later.
Vivace is not directed at children. Personalized ads in the free iPhone and iPad app require the permissions described in section 7. Optional usage analytics require the agreement described in section 8.
If we change how Vivace handles data, we will update this page and the “Last updated” date above. Material changes will also be reflected in the App Store privacy labels for the affected version.
Questions or requests about access, correction or deletion of data can be sent to mwsupplylimited@gmail.com. Include only what is needed to explain your request. We do not need your music files, passwords or Apple account credentials.
