The Short Version
Sampultu has no accounts, no analytics, and no server of ours for your content to go to. Everything you make happens between the app, your device, and the volca on the other end of the USB cable. We do not receive your audio, your files, or any record of what you do in the app.
Who We Are
Sampultu is provided by Best Practice. In this policy, “Sampultu,” “Best Practice,” “we,” “us,” and “our” refer to the people and systems that operate the app and related web pages at sampultu.madewithbestpractice.com.
Information You Provide
The app works with audio files you choose to open, samples you record, slices you chop, slot and bank names you type, pattern backups, and full device snapshots you save. This content is used only to provide the features you ask for: converting a sample, sending it to the device, reading one back, saving a backup, or exporting a file.
This content stays on your device and on your volca unless you choose to export or share it somewhere else yourself.
On-Device Processing
Audio decoding, downmixing, resampling, chopping, previewing, stem separation, file export, and every SysEx transfer to and from the volca happen on your device. There is no cloud processing step, and no part of a transfer is routed through us.
We do not use telemetry, behavioral analytics, crash reporting SDKs, advertising SDKs, or advertising identifiers. We do not know which samples you load, which slots you use, or that you opened the app at all.
Device Permissions
Sampultu asks for device permissions only when a feature needs them:
- Microphone — only if you record a sample directly in the app. Audio is captured on-device, becomes a sample you control, and is not sent to us. Nothing is recorded unless you start a recording, and you can decline the permission and still use every other feature.
- Files and storage — to open audio files you pick, and to save samples, exports, pattern backups, and snapshots where you choose.
- USB and MIDI device access — to find and talk to your volca sample 2. This is used to transfer samples, banks, and sequences and nothing else.
You can change these permissions in your device settings at any time.
Network Connections
Sampultu is built to work offline. It makes outbound network connections only in these cases, and only in response to something you do:
- Optional stem-separation models. If you choose to use stem separation on the Chop screen, the app offers to download the machine-learning models it needs (about 79 MB) one time, from Hugging Face. This is a plain file download; no personal data or identifiers are sent. After that one-time download the feature runs entirely on your device, offline, and you can delete the models later to reclaim the space.
- Sample-pack artwork and links. The Packs screen shows a curated list of third-party sample packs. While that screen is open, cover images load from the packs' publishers. Loading an image, like any web request, reveals your device's IP address and standard request metadata to that server. Choosing a pack opens the publisher's own page in your browser so you can download it there — the app itself does not download pack audio.
- External links. Links such as a credited tutorial video or our own website open in your default browser. Once a link opens, that site's own privacy policy applies.
The app does not phone home, does not check for updates over the network, and makes no other outbound connections.
Third-Party Services
Sampultu embeds no third-party analytics, advertising, or tracking SDKs. It interacts with third-party services only in the limited ways described above — the model host for the optional download, the sample-pack publishers whose cover images and pages you view, and any link you choose to open. Each is governed by its own privacy policy, which we do not control.
Purchases
The app does not currently include in-app purchases, subscriptions, or ads, and contains no billing or purchase SDK. If the app is distributed through the App Store or Google Play, those stores handle the download and any store-level payment under their own terms and privacy policies, and they may receive purchase and device metadata that we never see. If we add paid features later, we will update this policy before we do.
How We Use Information
Because the app sends us nothing, there is very little to use. We use information to:
- Run the app features you request, on your device.
- Respond to you if you contact us for support, using only what you choose to include in that message.
- Comply with applicable law and app-store requirements.
Sharing
We do not sell your personal information, and we have no user data to sell. We may share limited information with providers that help operate the app and this site, such as app stores and hosting providers. We may also disclose information if required by law or to protect the app, its users, or the public.
Retention
Samples, recordings, slices, exports, pattern backups, and snapshots remain on your device until you delete them, clear app data, or uninstall the app. Samples you send to the volca remain on the volca until you overwrite or delete them from the device. If you email us for support, we keep that correspondence for as long as needed to answer it.
Your Choices
You can decline the microphone permission and still use every other feature. You can skip the optional model download, delete the models afterwards, avoid the Packs screen, delete local files, uninstall the app, and choose never to export or share anything. Privacy questions can go to [email protected].
Children
Sampultu is a music-production utility for owners of a specific piece of hardware. It is not directed to children under 13, and we do not knowingly collect personal information from children under 13.
Changes
We may update this policy as the app changes. The effective date above reflects the latest version posted on this page.
