Terms of Use
LAST UPDATED · JULY 26, 2026
These Terms of Use ("Terms") govern your use of the Equalizer iOS application ("the App"), developed and published by Md Khaled Hasan ("we", "us"). By downloading or using the App you agree to these Terms. These Terms supplement, and where applicable incorporate, Apple's Standard End User License Agreement.
1. License
We grant you a personal, non-exclusive, non-transferable, revocable license to use the App on Apple devices that you own or control, for personal, non-commercial purposes, in accordance with these Terms and the App Store Terms of Service.
2. Free tier and Premium subscriptions
The App's core features are free. Additional features ("Premium") are available through auto-renewable subscriptions purchased via your Apple ID:
- Premium Weekly — billed every week
- Premium Yearly — billed every year
Current prices are always displayed in the App before purchase and are set in your local currency by the App Store. Subscription terms:
- Payment is charged to your Apple ID account at confirmation of purchase.
- Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; the renewal charge is applied within 24 hours before the period ends.
- You can manage or cancel your subscription at any time in your device's Settings → Apple ID → Subscriptions. Cancellation takes effect at the end of the current billing period.
- Purchases can be restored on a new device using Restore Purchases in the App's settings or paywall.
- All billing, refunds and payment disputes are handled by Apple under App Store policies; refunds can be requested at reportaproblem.apple.com.
3. DRM-protected content
The App applies its equalizer and audio effects to DRM-free music — files you import and DRM-free tracks in your device's music library. Audio protected by digital rights management (including streaming-subscription content) cannot be processed by the App or by any third-party iOS app; such tracks are identified in the App and play without effects. This limitation is disclosed in the App before any purchase, and Premium is sold on that basis.
4. Your content
You are responsible for the audio files you import into the App and must hold the necessary rights to use them. The App does not upload your files anywhere; they remain on your device. You agree not to use the App to infringe the intellectual-property rights of others.
5. Acceptable use
You agree not to reverse-engineer, decompile, resell, or redistribute the App; not to circumvent its purchase mechanisms; and not to use it in any unlawful manner or in violation of the App Store Terms of Service.
6. Hearing safety
The App can increase playback volume beyond normal levels. Listening at high volume for extended periods may damage hearing. You are responsible for choosing safe listening levels; a built-in limiter reduces distortion but does not make loud listening safe.
7. Intellectual property
The App, including its design, code, presets and branding, is owned by us and protected by applicable intellectual-property laws. These Terms grant you no rights other than the license in Section 1. Apple, Apple Music and the App Store are trademarks of Apple Inc.; the App is an independent product and is not affiliated with or endorsed by Apple.
8. Disclaimer of warranties
The App is provided "as is" without warranties of any kind, express or implied, including fitness for a particular purpose. We do not warrant that the App will be uninterrupted, error-free, or compatible with every audio file, accessory, or iOS version.
9. Limitation of liability
To the maximum extent permitted by law, we shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of the App. Our total liability for any claim shall not exceed the amount you paid for the App in the twelve months preceding the claim.
10. Apple's role
These Terms are between you and us, not Apple. Apple has no obligation to provide maintenance or support for the App and is not responsible for any claims relating to it. You acknowledge that Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
11. Changes and termination
We may update the App, its features, its prices (for future billing periods), and these Terms. Continued use after an update constitutes acceptance. We may terminate the license if you materially breach these Terms. You may stop using the App at any time by deleting it; active subscriptions must be cancelled separately as described in Section 2.
12. Governing law
These Terms are governed by the laws of your country of residence to the extent required by local consumer law, and otherwise by the laws applicable to the developer's place of business, without regard to conflict-of-law rules.
