Terms of Use

Agreeing to these terms

These Terms of Use ("Terms") are an agreement between you and Hoang Minh Duc ("I", "me", "my"), the independent developer who publishes the apps these Terms cover. By downloading, opening, or using any of those apps, you accept these Terms in full.

If you don't accept them, don't use the apps — and delete any copy already installed on your device.

If you're under the age of majority where you live, you may only use the apps with the involvement of a parent or legal guardian, who accepts these Terms on your behalf.

The apps these terms cover

These Terms apply to every mobile application published on the App Store under the developer name Hoang Minh Duc, together with any related websites, servers, and support channels I operate. Throughout this document they are referred to simply as "the apps".

Apps differ. Some let you create and store content, some use location or your camera, some include AI features, some are sold with subscriptions. A section of these Terms applies to an app only where that app actually has the feature described. If an individual app ever ships with its own additional terms, those take priority for that app, and everything here still applies to the rest.

Your licence to use the apps

I grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the apps on devices you own or control, in line with the App Store Terms of Service and Apple's Licensed Application End User Licence Agreement.

What you may not do

• Copy, sell, rent, sublicense, or redistribute the apps.
• Reverse-engineer, decompile, or attempt to extract the source code, except where that restriction is prohibited by law.
• Remove or obscure any copyright or ownership notice.
• Use the apps to build a competing product, or to scrape or bulk-export content that isn't yours.
• Interfere with the apps' servers, bypass usage limits, or automate access without my written permission.

Accounts and your responsibilities

Some features require an account or a sign-in. When you create one, give accurate information and keep your credentials to yourself. You're responsible for everything that happens under your account.

Tell me at binggu1996@gmail.com as soon as you suspect someone else is using it.

You're also responsible for your own device, your internet connection, and any charges your mobile carrier applies while you use the apps.

Subscriptions, billing, and refunds

Where an app offers paid features, they are sold through Apple's In-App Purchase system as a subscription, a one-time purchase, or consumable credits. The price, billing period, and what each purchase unlocks are shown in the app before you confirm.

How billing works

• Payment is charged to your Apple Account when you confirm the purchase.
• Subscriptions renew automatically unless you turn off auto-renew at least 24 hours before the current period ends.
• Your Apple Account is charged for renewal within 24 hours before the end of the current period, at the price shown at the time of purchase.
• Lifetime or one-time purchases apply for as long as the app remains available; they are not a guarantee that any specific feature or connected service will exist indefinitely.
• Prices vary by region and may change. Any price change for an existing subscription takes effect only after Apple notifies you, and never mid-period.
• Any unused portion of a free trial is forfeited when you buy a subscription covering the same features.

Managing or cancelling

Manage and cancel subscriptions in Settings → your name → Subscriptions on your device. Deleting the app does not cancel a subscription. Cancelling stops the next renewal; access continues until the end of the period you already paid for.

Refunds

Apple handles all payments, so Apple handles refunds. Request one at reportaproblem.apple.com. I can't issue refunds directly, but if something in an app went wrong, email me — I'd rather fix it.

Content you create

Anything you write, record, upload, or save in an app remains yours. I don't claim ownership of it.

To run the apps, I need a limited technical licence to that content: permission to store it, transmit it, back it up, and process it — including sending it to the service providers described in the Privacy Policy — for the sole purpose of delivering the features you asked for. That licence exists to operate the app and nothing else.

You confirm that you have the rights to the content you put into an app, and that it breaks no law and infringes nobody's rights.

Sharing and community features

Some apps let you publish content so other people can see it. This section applies only when you deliberately choose to share.

When you publish, you grant me a worldwide, royalty-free licence to display, distribute, and promote that content inside the app and in materials about the app, for as long as you keep it published. Unpublish or delete it and that licence ends, apart from copies already cached or held in backups for a limited period.

Published content carries the display name you chose. I may remove content that breaks these Terms, and I may — but am not obliged to — review published content before or after it appears.

AI features and generated content

Some apps use artificial intelligence to generate text, images, audio, suggestions, or recommendations. Where they do, please read this section carefully — it describes real limitations, not boilerplate.

• Output can be wrong. AI systems invent facts, misread inputs, and produce results that look confident and are not. Verify anything that matters before you rely on it.
• Output is not unique. The same or similar inputs can produce similar results for other people. I can't guarantee originality or exclusivity.
• Output may resemble existing work. The copyright status of AI-generated material differs by country and is unsettled in many of them. If you publish or sell what you generate, that's your call and your responsibility.
• You are responsible for what you generate. Don't use the apps to produce unlawful, deceptive, hateful, or infringing material.
• Availability depends on third parties. AI features rely on external providers and may be interrupted, rate-limited, or changed.

Acceptable use

Don't use the apps to:

• Break any law, or encourage anyone else to.
• Create or share sexual content involving minors, or content that sexualises real people without consent.
• Harass, threaten, defame, or impersonate anyone.
• Publish hateful content targeting people for who they are.
• Upload malware, or attempt to gain unauthorised access to any system or account.
• Misrepresent generated material as a factual record of real events or real people.

Accounts that break these rules can be limited or closed without notice.

Information the apps provide

Where an app shows maps, positions, weather, environmental conditions, measurements, forecasts, or similar real-world information, that information comes from third-party sources and from prediction. It can be delayed, incomplete, or simply wrong.

• Do not use the apps for navigation where accuracy affects safety. Use official charts, signage, and dedicated navigation equipment.
• Check an authoritative source before making a decision that depends on weather or environmental conditions.
• Suggestions and recommendations are predictions, not guarantees of any outcome, of safe conditions, or of lawful access.
• Nothing in the apps is professional, medical, legal, or financial advice.
• You remain responsible for following the licences, permits, seasons, restricted areas, and local rules that apply to what you're doing.

My intellectual property

The apps themselves — the code, design, interface, icons, names, and branding — belong to me and are protected by copyright and trademark law. Nothing in these Terms transfers any of that to you beyond the licence in section 03.

Third-party services

The apps rely on outside services, which may include Apple, cloud hosting, authentication and analytics providers, AI model providers, and data providers for things like maps or weather. Their own terms and privacy policies apply to their part of the service. I'm not responsible for third-party content, outages, or decisions, and their availability may change.

Changes and availability

I'm one person. Features can change, move, or be retired, and an app may be unavailable during maintenance, outages, or an App Store review. I don't promise uninterrupted service or that any specific feature will exist forever.

If I ever discontinue an app entirely, I'll give reasonable notice through the app or by email where I can, so you can export what's yours.

Suspension and termination

You can stop using the apps at any time by deleting them, and you can ask me to delete your account and data as described in the Privacy Policy.

I may suspend or end your access if you break these Terms, if it's necessary to comply with the law, or if keeping the service running for you creates a genuine risk to it or to other users. Sections that by their nature should survive termination — ownership, disclaimers, liability limits, and governing law — continue to apply.

Disclaimer of warranties

The apps are provided "as is" and "as available", without warranties of any kind, whether express or implied, including merchantability, fitness for a particular purpose, accuracy, and non-infringement, to the fullest extent permitted by law.

I don't warrant that the apps will be error-free or uninterrupted, that defects will be corrected, or that any result, recommendation, or generated output will be accurate or suitable for your purpose.

Some jurisdictions don't allow the exclusion of certain warranties, so parts of this section may not apply to you. Nothing here removes rights that consumer law gives you and cannot be waived.

Limitation of liability

To the fullest extent permitted by law, I am not liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits, lost data, or lost opportunities, arising from your use of — or inability to use — the apps.

My total liability for any claim relating to the apps is limited to the greater of the amount you paid me through in-app purchases in the twelve months before the claim, or USD 50.

This limit does not apply to liability that cannot be excluded by law, including death or personal injury caused by negligence, or fraud.

Indemnity

You agree to indemnify and hold me harmless from claims, damages, and reasonable costs arising from content you create or publish through the apps, your breach of these Terms, or your violation of anyone else's rights.

Apple as a third-party beneficiary

This agreement is between you and me, not Apple. Apple is not responsible for the apps or their content. Apple has no obligation to provide maintenance or support.

If an app fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price; to the maximum extent permitted by law, Apple has no other warranty obligation. Claims relating to the apps — including product liability, legal compliance, and intellectual property claims — are my responsibility, not Apple's.

Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

Governing law

These Terms are governed by the laws of the Socialist Republic of Vietnam, without regard to conflict-of-law rules. Disputes will be handled by the competent courts of Vietnam.

If you're a consumer in the EU, the UK, or another region whose law gives you the right to bring proceedings locally, that right is unaffected.

If any provision of these Terms is found unenforceable, the rest stays in force.

Changes to these terms

I may update these Terms when the apps change or the law requires it. The effective date at the top always reflects the current version. Material changes will be announced in the app or by email where I have your address. Continuing to use the apps after a change means you accept the updated Terms.
