Frequently asked questions | Jarvity
Will my data carry over to a new device?
Yes. As long as you are signed in with the same Apple ID, scores, settings, placements and purchases transfer automatically via iCloud. If purchases don't appear, try “Restore Purchases” in Settings.
I bought the app but still see ads
Try “Restore Purchases” in Settings. If that doesn't help, contact us with the Apple ID used and the purchase date.
Ads won't load
Check your connection. Ads cannot load offline, so rewarded items are unavailable in that state.
How do I change ad personalisation?
Settings → Privacy & Security → Tracking. In the EEA and UK you can also change it from “Privacy options” inside the app.
There's no sound
Check the silent switch, the volume, and the mute button at the top left of the app. Music and sound effects have separate volume sliders in Settings.
How do I delete my data?
Deleting the app removes on-device data. iCloud data can be managed from Settings → Apple ID → iCloud.
Is it safe for children to play?
Jarvity contains no violent content and does not push purchases. It does show ads, however, so for younger children we recommend using Screen Time on the device to restrict in-app purchases and web browsing.
Frequently asked questions | Acona
Is Acona the same thing as NEUTRINO?
No, they are separate. NEUTRINO is the engine that synthesises the singing voice; Acona is an editor for preparing the score you hand to that engine. Acona alone cannot produce a voice, and NEUTRINO works without Acona. Acona exists to make writing and adjusting that score less painful.
Do I need Acona in order to use NEUTRINO?
No. NEUTRINO runs on its own using the steps that come with it. What you will be doing, though, is entering lyrics one at a time and adjusting pitch curves as text. Acona lets you do that part on screen and in bulk. The more songs you work on, the more the difference shows.
Can I use the voice I make with Acona commercially?
The terms for the voice itself come from NEUTRINO and from the voice library you use, not from Acona. Acona only edits the score, so we place no restriction of our own on what you produce. Please check the NEUTRINO and voice-library terms before you publish or sell anything.
Is Acona available for Windows?
At present it is macOS only, and there is no Windows version planned right now. If that changes, we will announce it on this site.
Frequently asked questions | General
Do the apps work without an internet connection?
Jarvity plays fine offline; only loading ads needs a connection. Acona does its editing and synthesis on your own Mac, so the work itself needs no connection. To use the paid features, however, the app checks your license with our server at startup. If the check cannot be completed for 14 consecutive days, the software switches to the free range of use. You can still open your existing projects, edit them, and export without restriction. As soon as a check succeeds again, full use is restored immediately.And if the check has been unable to complete for 180 consecutive days, the software switches automatically to the permission last received (no expiry for an outright purchase; until the end of the contract period for an annual renewal). This switch takes place without any involvement on our part.
