Terms of Use

These Terms of Use (“Terms”) are an agreement between you and Black Knight Studio (“we”, “us”). Apps are published on the App Store under the developer name Yen Nguyen Thi Hai. By downloading, installing or using any of our apps, or by using this website, you agree to these Terms. If you don't agree, please don't use them.

We may update these Terms from time to time. When we do, we change the date at the top of this page. If you keep using our apps after a change takes effect, you accept the updated Terms.

These Terms cover the following apps, published by us on the Apple App Store:

• MixCam: Dual Video Recorder
• CertAnchor for AWS Exams
• AI Meeting Notes & Recorder
• Safe QR Code & Barcode Scanner
• Capword: AI Language Learning
• Tube Summary - AI Assistant
• AI Speech & Translation Text

They also cover future versions and updates of these apps. Features may change, be added or be removed over time.

Our apps are free to download. Some features are offered as in-app purchases, including auto-renewing subscriptions. The price, length and contents of each option are shown in the app before you buy.

• Payment is charged to your Apple Account when you confirm the purchase.
• A subscription renews automatically unless you cancel it at least 24 hours before the end of the current period. Your Apple Account is charged for the renewal within 24 hours before the period ends.
• You can manage or cancel subscriptions in Settings › Apple Account › Subscriptions. Deleting the app doesn't cancel a subscription.
• Purchases are processed by Apple, so refunds are handled by Apple under its policies. See Apple's billing and subscriptions help ↗ (opens in a new tab).

Apple's Licensed Application End User License Agreement ↗ (opens in a new tab) (Standard EULA) also applies to apps you get from the App Store. If it conflicts with these Terms, the Standard EULA controls for the conflicting part. Apple isn't responsible for our apps or their content.

You must be at least 13 years old to use our apps. If you are under the age of majority where you live, a parent or guardian must agree to these Terms for you.

You own the content you create or import with our apps, such as recordings, notes, photos and scans. We don't claim ownership of it. Where an app needs to send your content to a service provider to do what you asked (for example, transcribing a recording), you give us permission to process it for that purpose only, as described in our Privacy Policy.

You are responsible for your content and for having the right to record, import or share it. Respect other people's privacy: some places require everyone's consent before a conversation is recorded.

AI-generated results, such as summaries, transcripts, translations and explanations, can be inaccurate or incomplete. Check anything important before you rely on it.

Our apps, this website and everything in them that isn't your content — including software, designs, text, graphics, logos and practice questions — belong to us or our licensors and are protected by intellectual property laws. We give you a personal, non-exclusive, non-transferable, revocable license to use our apps for your own non-commercial purposes, in line with these Terms and the App Store rules.

Third-party names and trademarks mentioned in our apps belong to their owners and don't imply any affiliation or endorsement.

When you use our apps or this website, you agree not to:

• break any law, or infringe anyone else's rights, including privacy and intellectual property;
• copy, modify, distribute, sell or rent our apps or their content, except as the law allows;
• reverse engineer, decompile or try to extract the source code of our apps, except as the law allows;
• interfere with or disrupt our apps, servers or networks, or try to get around security or usage limits;
• use bots, scrapers or other automated means to access our apps or services;
• upload or send malware, or content that is unlawful, harmful, harassing or abusive.

We respect intellectual property rights. If you believe something in our apps or on this website infringes your copyright, email support@blackknight-studio.app with: your contact details; a description of the work; where the material appears; a statement that you believe in good faith the use isn't authorized; and a statement, under penalty of perjury, that your notice is accurate and that you are the owner or authorized to act for the owner. We review every notice and remove material where appropriate.

You can stop using our apps at any time by deleting them. We may suspend or end your access to our apps or services if you break these Terms, or if we need to for legal or security reasons. We may also stop offering an app or a feature. The parts of these Terms that by their nature should continue — such as ownership, warranty disclaimers, indemnity and limitation of liability — survive termination.

Our apps and this website are provided “as is” and “as available”. To the fullest extent the law allows, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose and non-infringement. We don't promise that our apps will be uninterrupted, error-free or secure, or that results will be accurate or meet your needs.

Our apps are tools, not professional advice. For example, a link safety check or allergen information is a helpful signal, not a guarantee, and practice questions don't guarantee an exam result.

To the extent the law allows, you agree to indemnify and hold harmless Black Knight Studio from claims, losses and expenses (including reasonable legal fees) that arise from your content, your misuse of our apps, or your breach of these Terms.

To the fullest extent the law allows, Black Knight Studio is not liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of data, profits, revenue or goodwill, arising from your use of our apps or this website.

Our total liability for all claims related to our apps or this website is limited to the greater of the amounts you paid for the app and its in-app purchases in the 12 months before the claim, or 20 US dollars (USD 20).

Some jurisdictions don't allow these exclusions or limits. Where that's the case, they apply only as far as the law permits.

These Terms are governed by the laws of Singapore and Vietnam, without regard to conflict-of-laws rules. This does not affect any mandatory consumer protection rights you have under the laws of the country where you live.

These Terms, together with our Privacy Policy and, for App Store apps, Apple's Standard EULA, are the whole agreement between you and us about our apps. If any part is found unenforceable, the rest stays in effect. If we don't enforce a part right away, we haven't waived it. You may not transfer your rights under these Terms; we may transfer ours as part of a merger, acquisition or sale of assets.
