Terms of Use
Last updated: 21 October 2026
These terms are an agreement between you and ISEMI Company Limited ("ISEMI", "we", "us") for the HeroCall app and service. By creating an account or using HeroCall you accept them. If you do not agree, please do not use the app.
Who can use HeroCall
You must be at least 18 years old and a parent or legal guardian of the children you add. You are responsible for your account, for keeping the Apple or Google account you sign in with secure, and for how the children in your family use the app.
What HeroCall is, and is not
Heroes are friendly characters voiced by artificial intelligence, not real people. They follow strict safety rules, but AI can make mistakes: a hero may misunderstand your child or say something inaccurate. HeroCall supports your parenting; it does not replace adult supervision, professional advice or emergency services. In an emergency, contact your local emergency number.
Minutes, Hero Pass and payments
- Call time is counted in minutes. New accounts get some free minutes. Minute packs are one-time purchases; their minutes do not expire, have no cash value and cannot be transferred.
- Hero Pass is an auto-renewable subscription, offered monthly or yearly. It unlocks every hero and mission, Hero Studio, more children, schedules and remote calls, and includes a number of minutes for each period, which end with that period.
- Payment is charged to your Apple Account or Google account when you confirm the purchase. A subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period; the renewal is charged within the 24 hours before the period ends. You can manage or cancel it at any time in your Apple Account or Google Play settings; cancelling stops the next renewal, and access continues until the end of the paid period.
- Purchases are processed by Apple or Google, and refunds are handled by them under their policies. Prices may differ by country and may change; a price change never applies to a period you have already paid for.
- One subscription funds one HeroCall account. You can restore your purchases on a new device from the store screen.
Your content
You keep ownership of what you add, such as child profiles, notes and custom heroes. You give us permission to store and process it only to provide HeroCall to you. When you upload a picture or describe a custom hero, you confirm that you have the right to use it and that it does not copy someone else's character or infringe anyone's rights. We may refuse or remove content that breaks these terms or our safety rules.
Acceptable use
Do not misuse HeroCall: for example, do not try to make heroes say harmful things, get around safety checks, access other people's data, reverse engineer or overload the service, or use it for any unlawful purpose. We may suspend or close accounts that do.
Our content
HeroCall, its heroes, voices, artwork, stories and software belong to ISEMI or its licensors. We give you a personal, non-transferable licence to use the app for your family, under these terms.
Ending your account
You can delete your account in the app at any time; this deletes your data as described in the Privacy Policy. Deleting your account does not cancel a store subscription: cancel it in your Apple Account or Google Play settings. We may end or suspend the service, or your access, if you seriously break these terms or if we have to by law; if we stop offering HeroCall we will tell you in advance where we can.
Disclaimers and liability
HeroCall is provided "as is" and "as available". To the extent the law allows, we do not promise that it will always be available, uninterrupted or error-free, and we are not liable for indirect or consequential losses. Our total liability for any claim is limited to the amount you paid us in the 12 months before the claim. Nothing in these terms limits rights you have as a consumer that cannot be excluded by law.
Apple App Store
If you downloaded HeroCall from the App Store, these terms are between you and ISEMI, not Apple. Apple has no obligation to provide maintenance or support, is not responsible for claims relating to the app, and is a third-party beneficiary of these terms with the right to enforce them. Where these terms do not cover something, Apple's Standard Licensed Application End User License Agreement applies.
Changes and governing law
We may update these terms; we will change the date at the top and tell you in the app about significant changes before they take effect. These terms are governed by the laws of Vietnam, without affecting the mandatory consumer protection laws of the country where you live.
