Effective 3 September 2026
1. Agreement
HyperVolume is made by Dayo Akinkuowo. By downloading or using it you agree to these terms. If you do not agree, please delete the app. Purchases made through the App Store are also covered by Apple's Licensed Application End User Licence Agreement, which applies alongside these terms.
2. Your licence
You get a personal, non-exclusive, non-transferable licence to use HyperVolume on devices you own or control, for your own use. You may not copy, resell, rent, reverse-engineer or redistribute the app, except where that restriction is void under the law where you live.
3. What HyperVolume is not
This matters more than anything else here, so it comes early.
- It cannot boost other apps. HyperVolume raises the volume of files you play inside HyperVolume. It has no effect on the system volume or on audio from any other app.
- It cannot boost streaming. Apple Music, Spotify, YouTube and every other streaming service deliver copy-protected audio. iOS does not permit any third-party app to process it. No app on the App Store can raise the volume of a streaming service, this one included.
If your library is entirely streaming, HyperVolume will have nothing to work with. There is a demo built into the app so you can hear what it does before paying for anything.
4. Your audio
You are responsible for the files you import. By importing a file you confirm you have the right to use it. Do not use HyperVolume to process audio you do not have the right to, and do not use it to attempt to circumvent copy protection of any kind. HyperVolume claims no ownership over anything you import; it stays yours, and it stays on your device.
5. Hearing and volume
HyperVolume can make audio much louder than your device would play it, by up to about +15 dB before compression and limiting. Loud audio through headphones damages hearing, and that damage is permanent and cumulative. The level meter in the app turns amber and then red as a warning, not as a target.
Use the lowest volume that works. Take breaks. If you have any concern about your hearing, speak to a medical professional. You use the volume boost at your own risk, and you are responsible for the levels you choose.
HyperVolume is not a hearing aid, not a medical device, and not a measuring instrument. Do not rely on it as any of those. The decibel figures it shows describe its own processing, not a calibrated measurement of what reaches your ear.
6. HyperVolume Premium, and payment
Some features require HyperVolume Premium. Subscription options and a one-off lifetime option are shown in the app, with the price and the period stated before you confirm.
- Payment is charged to your Apple ID when you confirm the purchase.
- A subscription renews automatically unless you turn off auto-renew at least 24 hours before the end of the current period.
- Your account is charged for renewal within 24 hours of the end of the current period.
- You can manage or cancel a subscription at any time in your device Settings, under your Apple ID. Deleting the app does not cancel a subscription.
- If a free trial is offered and you subscribe before it ends, any unused part of the trial is forfeited.
- Purchases attach to your Apple ID, not to an account with us. Restore Purchases in Settings is how you get Premium back on a new device.
Refunds are handled by Apple, not by us, under Apple's own policy. We cannot issue or refuse a refund on Apple's behalf.
7. Acceptable use
Do not use HyperVolume unlawfully, do not attempt to break or bypass its licensing, and do not interfere with its operation or with the services it depends on.
8. No warranty
HyperVolume is provided "as is" and "as available", without warranties of any kind, whether express or implied, including fitness for a particular purpose. Audio formats, file sources and iOS behaviour vary, and some files will not import or will not play. Nothing in this section removes rights you have under mandatory consumer-protection law where you live.
9. Limitation of liability
To the extent the law allows, we are not liable for indirect or consequential loss, for lost or corrupted files, or for hearing damage resulting from volume levels you chose. Where liability cannot be excluded, it is limited to the amount you paid for the app in the twelve months before the claim. Again, this does not affect mandatory consumer-protection rights.
10. Changes
HyperVolume changes over time, and features may be added, altered or removed. If these terms change, the new version is published here with a new effective date. Continuing to use the app after that means you accept them.
11. Governing law
These terms are governed by the laws of Nigeria, without regard to conflict-of-law rules, and the courts of Nigeria have exclusive jurisdiction — except that this does not deprive you of the protection of mandatory consumer-protection law where you live.
