Terms of Use

Effective date: 6 November 2026

These terms govern your use of the Mintwise mobile app (the “app”) and the website getmintwise.com, provided by Dang Duy Tu (Đặng Duy Từ), Tổ Tân Thanh 1, phường Tân Giang, tỉnh Cao Bằng, Vietnam (“we”, “us”). By using the app you agree to these terms. If you do not agree, please do not use the app.

Important: Coin identifications and prices in Mintwise are automated estimates. They are not an appraisal, authentication or financial advice. Before selling a coin that may be valuable, have it authenticated by a professional grading service such as PCGS or NGC.

1. The service

Mintwise lets you photograph a coin, suggests what coin it is with a confidence level, and shows catalog price estimates by condition. You can save coins to a collection stored on your device. No account is needed. How we handle data is described in our Privacy Policy.

2. Free scans

Each installation of the app includes 3 free scans. One scan is one coin (a photo of each side). A scan is not counted if the coin is not recognized, if the photo is not a coin, or if it fails because of a network or server error. Free scans are a one-time total for each installation and do not renew. Free scans are tied to the install ID on your device and have no cash value.

3. Subscriptions: yearly plan and 7-day pass

Mintwise Pro gives you scans beyond the free scans, subject to the fair use limits in section 4. You can get it in two ways.

  • Yearly plan: an auto-renewing subscription, with a 7-day free trial the first time you subscribe (see Free trial). It renews automatically every year at the then-current price until you cancel. On the App Store, cancel at least 24 hours before the renewal date to avoid being charged for the next year; on Google Play, cancel before the renewal date. You can cancel at any time (see How to cancel).
  • 7-day pass: a one-time purchase. It gives you Mintwise Pro for 7 days from the time you buy it, then ends by itself. It does not renew: you are charged once, and there is nothing to cancel. You can buy another pass after it ends.
  • Both are sold through the Apple App Store or Google Play and charged to your Apple or Google account. The price in your local currency, and whether the purchase renews, are shown in the app before you buy. Prices can differ between countries.
  • If we change the price of the yearly plan, Apple or Google will notify you in advance as required by their rules, and where required you will need to agree to the new price. A price change does not affect a 7-day pass you have already bought.

Free trial of the yearly plan

  • The yearly plan starts with a 7-day free trial. Each Apple ID or Google account can have it only once. If your store account has had it already, the app shows the regular price instead, and you are charged when you subscribe.
  • When the trial ends, it turns into the paid yearly plan automatically, and you are charged the yearly price shown in the app, unless you cancel before then: on the App Store at least 24 hours before the trial ends, on Google Play before the trial ends. The app shows the day you will be charged on the button you tap to start the trial.
  • To avoid being charged, cancel during the trial in your store account (see How to cancel). If you cancel during the trial, you are not charged.
  • We remind you 2 days before the trial ends: with a notification on your device if you allow them, otherwise in the app when you open it. The reminder is a courtesy: if you do not cancel, the trial still turns into the paid yearly plan.

How to cancel

Deleting the app does not cancel your subscription. Only the yearly plan renews, so it is the only one to cancel; a 7-day pass ends by itself. Cancel the yearly plan in your store account:

  • iPhone or iPad: open Settings, tap your name, then Subscriptions, choose Mintwise and tap Cancel Subscription.
  • Android: open the Google Play Store, tap your profile icon, then Payments & subscriptions, Subscriptions, choose Mintwise and tap Cancel subscription.

While you have the yearly plan, “Manage subscription” in the app’s Settings opens these screens. After you cancel, you keep Mintwise Pro until the end of the year you have paid for.

Refunds

Payments for the yearly plan and the 7-day pass are processed by Apple or Google, so refunds are handled by them under their refund policies; we cannot issue refunds directly. See our Support page for how to request one. If a refund is granted, Mintwise Pro from that purchase ends. Nothing in these terms limits any right you have under consumer protection law in your country.

Restoring purchases

If you reinstall the app or change device, use “Restore purchases” in the app (on the Mintwise Pro screen or in Settings) while signed in to the same Apple or Google account that made the purchase. This brings back a yearly plan that is still active. A 7-day pass is linked to the app on the device where you bought it; if you reinstall the app or change device before the pass ends and “Restore purchases” does not bring it back, contact us with the receipt from Apple or Google.

4. Fair use and abuse limits

To keep the service affordable and available for everyone, the yearly plan (including its free trial) and the 7-day pass include up to 30 scans per day, which is more than typical personal use. We may also limit the number of requests from a device or network in a short time. You agree not to:

  • access our service other than through the official app, including with scripts, bots or modified copies of the app;
  • create new install IDs or otherwise try to get around free scan or fair use limits;
  • copy, scrape or redistribute catalog data or prices shown in the app;
  • reverse engineer the app or interfere with the security of the service, except where the law allows it;
  • upload photos that are unlawful or that you have no right to use.

We may suspend scanning for an install ID that breaks these rules. If you have paid for the yearly plan or a 7-day pass, we will contact you or explain the reason in the app where we can.

5. Results and prices are estimates

  • Identification: results are produced automatically by an AI model and checked against a coin catalog. They can be wrong, especially with blurry photos, worn coins or hard-to-read dates. The confidence level is a guide, not a guarantee. Always compare the result with your coin, particularly the year and mint mark.
  • Prices: price estimates come from the Numista catalog for the condition you select, on the date shown. They are general catalog estimates, not offers to buy, and the amount a dealer or buyer will pay can be very different, often lower. Prices can change and may not exist for every coin.
  • Not professional advice: Mintwise does not grade coins, detect minting errors or authenticate coins, and nothing in the app is an appraisal, valuation for insurance or tax, or financial or investment advice. Get a professional opinion, such as authentication by PCGS or NGC, before buying, selling or insuring a coin that may be valuable.

6. Coin data from Numista

Catalog information and price estimates in the app come from Numista and are shown with their Numista catalog number (N#) and a link to the source. Numista data remains subject to Numista’s own terms. Mintwise is not affiliated with or endorsed by Numista.

7. Your photos and our app

You keep all rights to the photos you take. You give us permission to process them only to provide the scan, as described in the Privacy Policy; we do not keep them. The app, its design, text and software belong to us or our licensors. We grant you a personal, non-exclusive, non-transferable licence to use the app on devices you own or control, under these terms and the usage rules of the App Store or Google Play.

8. Changes and availability

We work to keep the service running, but scanning depends on internet access and on third-party providers, and may sometimes be unavailable. We may change or improve features. If we stop offering the service, we will give reasonable notice in the app, and you can cancel your subscription.

9. Disclaimer and limitation of liability

To the extent permitted by law, the app is provided “as is” and “as available”, without warranties of any kind, including that results or prices are accurate or complete. To the extent permitted by law, we are not liable for indirect or consequential losses, or for losses arising from decisions to buy, sell or value a coin based on the app, and our total liability is limited to the amount you paid for the app in the 12 months before the claim.

These limits do not apply where the law does not allow them, for example liability for death or personal injury caused by negligence, or for fraud. If you are a consumer in the UK, the EU or Australia, you have statutory rights that these terms do not affect, including guarantees under the Australian Consumer Law.

10. Apple App Store

If you downloaded the app from the Apple App Store, these terms are between you and us, not Apple. Apple is not responsible for the app or its content, has no obligation to provide maintenance or support, and is not responsible for any claims relating to the app. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you. Apple’s Standard Licensed Application End User License Agreement also applies where these terms do not cover a point.

11. Governing law and disputes

These terms are governed by the laws of Vietnam. If you are a consumer, you also benefit from any mandatory protections of the law of the country where you live, and you may bring a claim in the courts of that country. Before starting a formal dispute, please contact us so we can try to resolve the issue.

12. Changes to these terms

We may update these terms. We will change the effective date above and, for material changes, tell you in the app before they take effect. If you continue to use the app after that, the new terms apply.
