Important: some of these Terms limit our responsibility or place risk on you. Please read Section 5 (we are not responsible if your content is lost through device failure, uninstalling the App, clearing App data, or problems with your Google account), Section 6 (results and exchange rates may be wrong, so check important results yourself), Sections 7 and 10 (we are not responsible for Google’s or other third-party services), Section 9 (Pro Lite can change or end at any time), Section 12 (the App is provided “as is”), Section 13 (we are not liable for losses caused by relying on results, and our liability is capped), Section 14 (you may have to cover our costs if you break these Terms), and Section 18 (we are not responsible for events outside our control). None of this limits your rights under consumer protection laws (see Section 12).
These Terms and Conditions (“Terms”) are an agreement between you and 3MD FAMILY (PTY) LTD (“we,” “us,” or “our”) about your use of the MinteCalc mobile application (the “App”). By downloading or using the App, or by buying MinteCalc Pro, you agree to these Terms. If you do not agree, please do not use the App.
Our Privacy Policy explains how we handle your information. Please read it too.
Your rights as a consumer: if you are a consumer, the mandatory consumer protection laws of the country where you live still apply to you. Nothing in these Terms takes away rights you have under those laws.
You must be at least 13 years old. If you are under the age of majority where you live (18 in many countries), you may use the App and make purchases only with the permission of a parent or legal guardian.
We give you a personal, limited, non-exclusive, non-transferable license, revocable only as described in Section 15, to install and use the App on devices you own or control, for your own personal use, including in your own work or business. All rights not expressly granted to you are reserved by us. If you downloaded the App from the Apple App Store, Section 18.1 also applies.
Updates: we may release updates to fix problems, improve the App, or keep it working with new versions of iOS and Android and with the services it relies on. Some updates may be required: the App may ask you to install an update before you can keep using it, for example for security reasons or when an older version no longer works with a service it relies on. We may also stop supporting older versions of iOS or Android. Updates are free, and Section 8.1 explains how we handle changes to Pro features.
You agree not to:
You own the calculations, notes, and other content you create in the App (“Your Content”). Your Content is stored on your device and, if you choose, in your own Google Drive. We do not claim any rights to it.
Please keep your own backups. We are not responsible for loss of Your Content caused by device failure, uninstalling the App, clearing App data, or problems with your Google account.
The App is a general-purpose tool. We work hard to make it accurate, but we do not guarantee that every calculation, conversion, or result will be correct, complete, or suitable for your purpose. Always check important results yourself, especially for taxes, loans, investments, business, academic, medical, legal, or safety-related decisions.
Exchange rates, including cryptocurrency prices such as Bitcoin, are provided for general information and reference only. They come from our third-party data provider, FXRatesAPI, are updated periodically rather than in real time, and may be delayed, cached while you are offline, inaccurate, or unavailable. They are not the rates a bank or exchange service will give you.
Google Drive Sync is an optional Pro feature. If you use it:
We are not responsible for interruptions or failures of Google’s services. You can delete your backup and sign-in reference, or sign out, at any time, with or without Pro (see our Account and Data Deletion page).
MinteCalc Pro removes ads and unlocks premium features, such as unlimited notes, Google Drive Sync, custom app icons, extra note display options, and personalization options. Pro is available as:
The free version lets you save a limited number of notes, and the App tells you when you reach the limit. We may change this limit. You always keep the notes you have already saved: you can still open, edit, delete, back up, and restore them. To add a note when you are at the limit, delete a note, start a Pro Lite pass (see Section 9), or get Pro.
We may change Pro features for valid reasons, such as keeping the App working with new versions of iOS and Android, security, changes in the law, or changes to a service the App relies on, such as Google Drive. These changes will not cost you extra. Whether you have a subscription or a lifetime purchase, we will not materially reduce the core Pro benefits you paid for (no ads, unlimited notes, Google Drive Sync, custom app icons, and personalization options such as accent colors, display fonts, and note styles), unless a reason outside our control requires it, such as a change to Google Drive or to Apple’s or Google’s rules. If a change would make Pro noticeably worse for you, we will tell you in the App before it takes effect, and you can cancel your subscription. This does not affect any right you have under consumer law to a refund.
For purchases through Apple, refunds are processed by Apple, so you can request one at reportaproblem.apple.com. If Apple does not refund you and consumer law entitles you to a remedy from us, email us at support@mintecalc.com. For purchases through Google Play, you can request a refund from Google Play within 48 hours of buying. After that, email us at support@mintecalc.com with your order number (it starts with GPA), and we will review your request. Except where the law or the app store’s policy requires a refund, payments are non-refundable. If Pro does not work as described or has a fault, you may be entitled to a repair, a replacement, or a refund under consumer law (see Section 12).
If you live in the European Union or the United Kingdom, you may also have a legal right to cancel a purchase within 14 days. For purchases made through the App Store or Google Play, Apple or Google handles these requests under its own terms and the law where you live.
We may change subscription prices. A new price applies only from your next billing period, and Apple or Google will notify you and, where required, ask for your consent first. If you do not agree to a new price, you can cancel before it takes effect.
The free version of the App shows ads provided by Google AdMob. How ads use your information, and how to change your choices, is explained in our Privacy Policy.
Pro Lite: you can choose to watch a rewarded ad to start a Pro Lite pass. A pass gives you most Pro features for a limited time, shown in the App. It does not include Google Drive Sync or custom app icons. During a pass, the App may pause full-screen ads, but the banner ad stays. Please note that:
When a pass ends, notes you added during it stay saved. Some choices, such as your accent color, display font, and note emoji and color, stay until you change them. Others, such as note display options, return to their defaults. Changing a Pro option again needs a new pass or Pro.
The App relies on services from third parties, including Google (Firebase, AdMob, Google Sign-In, Google Drive, and Google Fonts), RevenueCat, Apple, and our currency rate provider, FXRatesAPI. Their services are covered by their own terms and privacy policies. We are not responsible for their availability, accuracy, or practices. The full list, and what each one does, is in our Privacy Policy.
The App, including its design, code, graphics, and content (but not Your Content), belongs to 3MD FAMILY (PTY) LTD and is protected by intellectual property laws. “MinteCalc” and the MinteCalc logo are our trademarks, and you may not use them without our written permission.
If you send us feedback or suggestions, we may use them to improve the App without any obligation to you.
Your legal rights: if you are a consumer, laws in many places, including the UK, the EU, Australia, and South Africa, give you rights that these Terms cannot take away. For example, the App and MinteCalc Pro must match their description, be of satisfactory (or acceptable) quality, and be fit for purpose. If they are not, you may be entitled to have the problem fixed, or to a price reduction or refund. Sections 5, 6, 12, 13, and 14 do not limit these rights. If you are in Australia, our goods and services come with guarantees that cannot be excluded under the Australian Consumer Law.
To the fullest extent permitted by law, the App is provided “as is” and “as available,” without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not promise that the App will always be available, uninterrupted, secure, or free of errors.
Some countries and U.S. states do not allow certain warranties to be excluded, so some of these exclusions may not apply to you.
To the fullest extent permitted by law:
Nothing in these Terms limits liability that cannot be limited by law, including liability for fraud, gross negligence, intentional misconduct, or death or personal injury caused by negligence, and including your rights under mandatory consumer laws (such as South Africa’s Consumer Protection Act, or consumer laws in the EU, the UK, Australia, and elsewhere).
To the extent permitted by law, you agree to compensate us for claims, losses, and reasonable legal costs that arise because you broke these Terms or infringed someone else’s rights through your use of the App.
You can stop using the App at any time by uninstalling it. Remember to cancel any subscription through your app store, and to delete your backup if you wish (see our Account and Data Deletion page).
We may suspend or end your access to the App if you seriously or repeatedly break these Terms (where we reasonably can, we will warn you first), if the law requires it, or if needed to protect the security of the App or its users. If we decide to discontinue the App, we will tell you in the App at least 30 days before and stop selling new subscriptions and lifetime purchases. If you have paid for a subscription period that we will not provide, you can ask for a refund for the unused part, as the law requires (for App Store purchases, see Section 8.3). This does not affect any refund or other rights you have under the law or app store policies.
Sections 5, 6, and 11 to 18 continue to apply after these Terms end.
We may update these Terms as the App or the law changes. We will post the new version on this page and update the “Last Updated” date. For significant changes, or changes that reduce your rights, we will let you know in the App at least 30 days before they take effect, unless a change is needed sooner for legal or security reasons. Changes to these Terms will not take away the Pro benefits of a lifetime purchase. If you do not agree with a change, you can stop using the App and cancel your subscription before the change takes effect, and where the law gives you a right to a refund for the unused part, you can ask for it. Otherwise, the updated Terms apply once they take effect.
These Terms are governed by the laws of the Republic of South Africa, without regard to conflict of law rules.
If you have a concern, please contact us first at support@mintecalc.com. Most issues can be resolved quickly this way. If we cannot resolve a dispute within 60 days, either of us may take it to the courts of South Africa. If you are a consumer, you do not have to wait for the 60 days to end before using your rights under consumer law. In South Africa, you can also complain to the Consumer Goods and Services Ombud (CGSO) or the National Consumer Commission.
If you are a consumer, you also keep the protection of the mandatory laws of the country where you live, and you may bring a claim in the courts of that country or complain to your local consumer protection authority.
If you downloaded the App from the Apple App Store:
If you downloaded the App from Google Play, your use is also subject to the Google Play Terms of Service. Google is not a party to these Terms and is not responsible for the App.
