Terms of Use
The Groovalizer app for iPhone, iPad and Android · Last updated October 2, 2026
Agreement
These terms apply when you use the Groovalizer app, made by Max Kucera ("we", "us"). By using the app you agree to them. If you downloaded the app from the Apple App Store, Apple's Licensed Application End User License Agreement also applies; where the two differ, these terms apply to the extent the law and Apple's rules allow.
Your licence
We give you a personal, non-exclusive, non-transferable licence to use the app on devices you own or control, for your own non-commercial enjoyment and for making videos to share on your own social media.
The app, its visuals, presets, artwork and Groov Beats music belong to us or our licensors. Open-source components are licensed under their own terms, listed in Settings → Licences.
Groovalizer Pro subscriptions
Pro is an auto-renewing subscription. The price and billing period are shown before you buy. Payment is charged to your Apple ID or Google account when you confirm the purchase, or when a free trial ends.
Your subscription renews automatically unless you cancel at least 24 hours before the end of the current period. You can manage or cancel it in your App Store or Google Play account settings, and from Settings in the app. Cancelling stops future renewals; you keep Pro until the end of the period you have paid for.
If you start a free trial, you will not be charged during the trial. If you cancel before it ends, you will not be charged at all. Any unused part of a free trial ends when you buy a subscription.
Refunds are handled by Apple or Google under their policies.
Your music, photos and videos
You keep all rights in the music, photos and recordings you use with Groovalizer. You are responsible for having the right to use them, especially when you share videos publicly. Many streaming services and record labels do not allow their music to be reposted; Groov Beats are provided so you always have music you can use.
Groov Beats may be used as the soundtrack of videos you make with Groovalizer and share on social media, including monetised accounts. They may not be extracted, resold or distributed on their own.
Free videos include a small Groovalizer watermark. Please do not remove it; Pro removes it for you.
Health and safety
Groovalizer shows moving, flashing and high-contrast visuals. If you or anyone watching has photosensitive epilepsy or is sensitive to flashing light, consult a doctor before use and stop immediately if you feel unwell. You can slow the visuals and reduce their intensity in Tweak.
Acceptable use
Do not use the app to break the law or infringe anyone's rights, and do not copy, reverse engineer or resell the app except where the law allows it (including the rights granted by the open-source licences of its components).
Disclaimers and liability
The app is provided "as is". We work hard to make it reliable but cannot promise it will always be available, error-free or work on every device.
To the extent the law allows, we are not liable for indirect or consequential losses, and our total liability to you is limited to the amount you paid us in the 12 months before the claim. Nothing in these terms limits rights you have under consumer law that cannot be excluded.
Changes and contact
We may update these terms. If a change is significant, we will tell you in the app. Continuing to use the app after a change means you accept the new terms.
