Privacy

LAST UPDATED · 9 NOVEMBER 2026

Short version

This website and our apps don't ask you for an account, don't show ads, don't track you and don't sell or share your data. Our apps don't connect to the internet: what you make with them stays on your device until you decide to share it.

Who is responsible

Victor Manuel Cuenca Blanco, tax ID 47077233M, trading as VTRsoftware. Address: Partida el Planet, 7, 03590 Altea, Spain. Contact: hi@vtrsoftware.com.

This website

vtrsoftware.com uses no cookies, no analytics and no third-party fonts or scripts. The hosting provider may log technical data for each request (IP address, browser, time) for security and operation, as any web server does. We don't use it to identify you.

If you email us, we use your address and message only to reply, and delete them once the conversation no longer needs them.

Our apps

This section covers pureSynth (Android) and Dragger Synth (Android and iPhone/iPad).

What we don't do

• No sign-up or account.
• No ads, no advertising SDKs and no analytics.
• No crash-reporting or tracking services from us or from third parties.
• No internet access: the apps have no network permission, so they can't send anything anywhere.
• No microphone: recordings are made from the app's own sound.

What stays on your device

• Projects, loops and sounds are saved in the app's private storage. If your phone's own backup is on (Google on Android, iCloud on iPhone and iPad), it keeps a copy in your account so your projects come back when you reinstall or change phone; we never see it. Uninstalling the app deletes them from the device.
• Exports (audio and MIDI files) leave the app only when you choose to: through the system's share menu or file picker, to the app or folder you pick.
• Earlier versions. On its first launch after an update, pureSynth reads the sounds and sequences saved by pureSynth Pro (2018) on the same device and imports them locally.

Permissions

• Bluetooth (Dragger Synth): to find and connect the Bluetooth MIDI keyboards and controllers you choose. It's only asked for when you look for one. USB MIDI needs no permission.
• Storage (pureSynth, Android 8 and 9 only): for “Save to Music”. Newer Android versions don't need it.

You can revoke any permission in your system settings; the rest of the app keeps working.

Purchases

Apps and optional sound packs are paid through Google Play or the App Store. They handle the payment under their own privacy policies; we only receive confirmation that a purchase was made, never your payment details.

Crash reports from the stores

Google Play and Apple may send us anonymous, aggregated crash and performance reports (for example, device model and system version) if you allowed this in your device settings. They don't identify you, and you can turn them off at any time: on Android under Google settings → Usage & diagnostics; on iPhone/iPad under Settings → Privacy & Security → Analytics & Improvements → Share With App Developers.

Your rights

You can ask for access, correction, deletion, objection, restriction and portability of your data by writing to hi@vtrsoftware.com. If you think we haven't handled your request properly, you can complain to the Spanish Data Protection Agency (aepd.es).

Children

We don't knowingly collect personal data from anyone, children included. Our apps need no account or personal data, so they can be used without giving us any.

Changes

If something important changes, for example an app starts using the internet, we'll update this page and the date above before that version is released.
