Terms of Service
Last updated 14/09/2026
These terms are an agreement between you and The Music Guy Studio (SSM Reg. No. CA0314602-P) ("we", "us"), based in Malaysia, for your use of the Interval Hero app. By creating an account or using the app, you agree to them.
Who can use Interval Hero
- To create your own account, you must be 16 or older.
- A child under 16 may use the app through an account created and managed for them by a responsible adult: their teacher or parent. That adult is responsible for the child's use.
Your account
Keep your password private and your account secure. You're responsible for what happens under your account. Tell us promptly if you think someone else has access. Adding an email is optional but is the only way we can help you recover a lost password.
Subscriptions and billing
Interval Hero has a free tier and paid features. Payments are processed by Stripe. Our plans are:
| Plan | Price |
|---|
| Individual, monthly | RM15 / month (US$3.99 outside Malaysia) |
| Individual, annual | RM150 / year (US$34.99 outside Malaysia) |
| Teacher Pro, monthly | RM25 / month (US$12 outside Malaysia); includes 3 student seats |
| Teacher Pro, annual | RM250 / year (US$120 outside Malaysia); includes 3 student seats |
| Extra student seat | RM7 / month or RM70 / year each (US$3 / US$30 outside Malaysia) |
- An Individual plan starts with a 7-day free trial the first time you subscribe. A payment method is required when the trial begins; you are not charged during the trial, and your card is charged automatically for the first period when the trial ends unless you cancel before then. If you have already used your free trial, subscribing again begins a paid subscription immediately, with no further trial. Teacher Pro does not include a free trial; billing begins at checkout.
- Paid plans renew automatically until you cancel. You can cancel at any time; see our Refund Policy for how the trial, cancellation and refunds work.
- Prices are shown in Malaysian Ringgit within Malaysia and in US Dollars elsewhere, and may include applicable taxes. We may change prices, but not for a billing period you've already paid for; we'll give notice of a change before it takes effect.
Teacher accounts and student seats
- A Teacher Pro subscription includes 3 student Pro seats. Additional seats are billed per seat at the rate shown at checkout.
- The teacher is the sole account holder and payer for their subscription and for every seat on it. Students on a teacher's roster are not billed and take on no payment obligation.
- Cancelling Teacher Pro removes Pro access from any student seat granted through it. A student who separately holds their own Individual subscription keeps it.
- Seat changes take effect immediately and are prorated by our payment provider; refunds follow the Refund Policy.
- Founder pricing, where offered, locks the founder rate on the base plan and all seats for as long as the subscription stays active; letting it lapse and resubscribing preserves the founder rate. Standard pricing for non-founder accounts may change on notice.
- The teacher is responsible for having the right to create and manage each student account, including parental consent where a student is a minor, as described in our Privacy Policy.
Acceptable use
Please don't:
- break the law, or use the app to harm or harass anyone;
- try to break, overload, or gain unauthorised access to the app or other accounts;
- copy, resell, or redistribute the app's content without permission;
- share an account to avoid paying for multiple users.
Display names and leaderboards
If you choose a public display name for a leaderboard, keep it clean and non-identifying: no real full names, contact details, offensive, or impersonating names. We screen names and may remove or reset any that break this rule. The global cross-studio leaderboard is off by default; you appear on it only if you opt in.
Our content and yours
The app, its design, and its exercises belong to us. Your practice data belongs to you; by using the app you allow us to store and process it to provide the service, as described in our Privacy Policy.
Availability
We work to keep Interval Hero running well, but we can't promise it will always be available or error-free. We may update, change, or pause features.
Ending your use
You can stop using Interval Hero and delete your account at any time. We may suspend or close an account that breaks these terms or is used fraudulently; where fair, we'll give notice first.
Liability
Interval Hero is provided "as is". To the extent the law allows, we are not liable for indirect or consequential loss arising from your use of the app. Nothing in these terms limits rights you have under Malaysia's Consumer Protection Act 1999 or other laws that cannot be excluded.
Governing law
These terms are governed by the laws of Malaysia, and disputes are subject to the Malaysian courts.
Changes
We may update these terms as the app develops. We'll update the date above and, for significant changes, give clearer notice in the app.
