Terms of Use

End User License Agreement Last updated: June 28, 2026

These Terms of Use ("Terms") are a legal agreement between you ("you" or "your") and Emanuele Pio Totaro ("Buck," "we," "us," or "our"), the developer and operator of the Buck mobile application and related services (together, the "App" or the "Service").

These Terms of Use ("Terms") are a legal agreement between you ("you" or "your") and Emanuele Pio Totaro ("Buck," "we," "us," or "our"), the developer and operator of the Buck mobile application and related services (together, the "App" or the "Service"). The developer of record for the App on the Apple App Store is Emanuele Pio Totaro (Apple Developer Team ID X9RA7Z26V7).

PLEASE READ THESE TERMS CAREFULLY. THEY CONTAIN IMPORTANT INFORMATION ABOUT YOUR LEGAL RIGHTS, INCLUDING AN AUTO-RENEWING SUBSCRIPTION, DISCLAIMERS ABOUT ESTIMATED VALUES, A DISCLAIMER OF WARRANTIES, AND A LIMITATION OF OUR LIABILITY.

1. Acceptance of These Terms

By downloading, installing, accessing, or using the App, by tapping "Agree," "Continue," "Start," or a similar control during onboarding, or by purchasing a subscription, you confirm that you have read, understood, and agree to be bound by these Terms and by our Privacy Policy, which is available at https://getbuckapp.com/privacy and inside the App in Settings. If you do not agree to these Terms, do not download, install, or use the App, and cancel any purchase in accordance with Apple's policies.

We may update these Terms from time to time. When we make material changes, we will update the "Last updated" date above and, where appropriate, provide notice inside the App. Your continued use of the App after changes take effect means you accept the revised Terms. If you do not agree to the revised Terms, stop using the App.

2. Eligibility and Age

The App is rated for general audiences and its content (coins, banknotes, and collecting) is age-appropriate. To use the App you must be at least 13 years old, or the minimum age of digital consent in your country if that age is higher. If you are under the age of majority in your place of residence, you may use the App only with the involvement and consent of a parent or legal guardian who agrees to be bound by these Terms.

By using the App you represent and warrant that you meet these age requirements, that you have the legal capacity to enter into these Terms, and that you are not barred from using the App under the laws of your jurisdiction. We do not knowingly collect personal information from children in a manner that requires verifiable parental consent. If you believe a child has provided us information improperly, contact us at privacy@getbuckapp.com.

3. License Grant

Subject to your compliance with these Terms, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to download and use one copy of the App on an Apple-branded device that you own or control, solely for your personal, non-commercial use, and as permitted by the Apple App Store Terms of Service and the Usage Rules in the Apple Media Services Terms and Conditions.

This is a license, not a sale. We and our licensors retain all right, title, and interest in and to the App. You receive no rights other than those expressly granted in these Terms. The scope of this license is further described in the Apple-required terms in Section 18.

4. Description of the Service

Buck is an iOS application that helps you identify coins and banknotes from a photo, see an estimated market value or value range for an item, and keep track of a personal collection. Core features include:

  • Scanning a coin or banknote with your device camera, or importing an image from your photo library, so the App can attempt to identify the item (for example country, denomination, year, mint mark, variety, and name) using artificial intelligence.
  • Showing an estimated value or reference range for identified items, where available. See the important disclaimers in Section 6.
  • Letting you build and view a personal collection of items on your device.
  • Showing illustrative community-style content, such as example "finds," example sale amounts, and example leaderboard or location features, that is provided to demonstrate how the App works. See Section 7.

How identification works: when you scan or import an image, the App sends that image to our backend service, which in turn sends it to a third-party artificial intelligence provider (Google Gemini) for the sole purpose of identifying the item. Our backend is designed to process the image to service your request and does not maintain a user account or user profile for you. Any value or grade suggested by the AI model is not used; value information, where shown, is generated separately. We obtain your consent before the first image is sent for processing, and we describe this data flow in our Privacy Policy.

Features may change, be added, or be removed over time. Some features may be in development, shown as examples, or offered on a limited or beta basis. We do not guarantee that any particular feature will be available at any given time.

5. Subscriptions, Free Trial, Billing, and Cancellation

Some features of the App require a paid auto-renewing subscription ("Subscription"). The following terms describe the Subscription and are intended to satisfy Apple's App Store requirements for auto-renewing subscriptions, including Guideline 3.1.2(a). The specific Subscription name, price, billing period, and any free trial length are shown on the purchase screen (the "paywall") inside the App before you buy, in your local currency.

5.1 Auto-Renewing Subscription

  • The Subscription is billed in advance on a recurring basis for the billing period you select (for example weekly, monthly, or yearly), as shown on the paywall before purchase.
  • Payment is charged to your Apple Account at confirmation of purchase.
  • The Subscription automatically renews at the then-current price for the same billing period unless you cancel it at least 24 hours before the end of the current period.
  • Your Apple Account is charged for renewal within 24 hours before the end of the current period.
  • The exact price, billing period, and what is included are presented on the paywall before you complete a purchase. We will not charge you a renewal without making the price and period available to you in the purchase flow.

5.2 Free Trial (if offered)

  • If a free trial is offered, the length of the trial and the price that will be charged when the trial ends are shown clearly on the paywall before you start.
  • Unless you cancel at least 24 hours before the trial ends, the trial automatically converts into a paid auto-renewing Subscription, and your Apple Account is charged the price shown.
  • Any unused portion of a free trial is forfeited when you purchase a Subscription, where applicable.

5.3 Billing Through Apple

All purchases of the Subscription are processed by Apple through your Apple Account using Apple In-App Purchase. We do not collect or process your payment card details. Your purchase is also subject to the Apple Media Services Terms and Conditions. Because Apple handles billing, your Subscription, payment method, billing history, and renewal settings are managed by Apple, not by us.

5.4 How to Cancel

You can cancel your Subscription at any time, and you manage and cancel it through Apple, not inside the App. To cancel:

  1. Open the Settings app on your iPhone.
  2. Tap your name at the top, then tap Subscriptions. (You can also open the App Store, tap your profile icon, then tap Subscriptions.)
  3. Tap Buck.
  4. Tap Cancel Subscription and confirm.

Cancellation takes effect at the end of the current billing period. After cancellation you keep access to paid features until the end of the period you already paid for, and you will not be charged again unless you resubscribe. Deleting the App does not cancel your Subscription; you must cancel through Apple as described above. For more help, see Apple's instructions at https://support.apple.com/en-us/HT202039.

5.5 No Refunds By Us

Subscriptions are billed and refunded by Apple, not by us. Except where required by applicable law, payments are non-refundable and we do not provide refunds or credits for partial billing periods, unused periods, or features you did not use. Because Apple processes all payments, any refund request must be made to Apple, for example through https://reportaproblem.apple.com, and is subject to Apple's policies. We have no ability to issue refunds for App Store purchases.

5.6 Price Changes

We may change the Subscription price from time to time. If we increase the price of an auto-renewing Subscription, Apple will notify you in accordance with its rules, and the increased price will not take effect for you until you agree to the new price where Apple's policies require your consent. Where your affirmative consent is not required by Apple's policies, the new price will apply at your next renewal after notice, and you may cancel before that renewal if you do not agree. Price changes do not apply retroactively.

5.7 Restore Purchases

If you reinstall the App or use a new device signed in to the same Apple Account, you can restore an active Subscription using the "Restore Purchases" control in the App. Restoring relies on Apple's records of your purchase.

6. Value Estimate Disclaimer (Please Read)

This Section is important. By using the App you acknowledge and agree to the following.

  • Estimates only. Any value, price, value range, or "what it is worth" information shown in the App is an automated estimate or a reference range generated using artificial intelligence and available market data. It is provided for informational and entertainment purposes only.
  • Not a professional appraisal. The App does not provide, and is not a substitute for, a professional appraisal, authentication, grading, or certification. Buck is not a coin dealer, not a numismatist, not a grading service, not an auction house, and not a professional appraiser, and the App does not authenticate or grade any item.
  • Not financial or investment advice. Nothing in the App is financial, investment, tax, legal, or trading advice, or a recommendation to buy, sell, or hold any item. You are solely responsible for any decision you make.
  • Not a guarantee of sale price. An estimate is not an offer to buy or sell, and is not a guarantee that you can buy or sell an item at, above, or below the estimated value. The actual amount you could receive depends on many factors we do not control, including the item's true condition, grade, authenticity, rarity, completeness, provenance, demand, the specific buyer, fees, and timing.
  • Markets fluctuate. Collectible markets are volatile. Prices change frequently and an estimate may be out of date, incomplete, or inaccurate at any moment. Estimates may be based on limited data and may not reflect your specific item.
  • Consult a professional. For any item that may be valuable, or before you buy, sell, insure, or make any decision based on value, you should consult a qualified independent professional, such as a reputable dealer, a recognized grading service, or a certified appraiser, and verify authenticity and condition independently.

You rely on value information at your own risk, and we are not responsible for any loss arising from your reliance on it. The limitations of liability in Section 12 apply fully to value information.

7. Accuracy and AI Disclaimer

The App uses artificial intelligence to identify coins and banknotes from images. Artificial intelligence can be wrong. Identifications, attributes (such as country, denomination, year, mint mark, or variety), confidence indicators, and any related output may be incomplete, inaccurate, or incorrect, and the App may fail to identify an item or may misidentify it. Results depend on factors including image quality, lighting, focus, the condition of the item, and the limits of the underlying model and data. You should independently verify any identification before relying on it. The App is a tool to assist you, not an authority, and it does not detect counterfeits or guarantee authenticity.

8. Community and Illustrative Content ("Live Finds" and Similar)

The App may display content that is illustrative and provided to demonstrate how features look and work. This includes, for example, sample "Live Finds" activity, sample "finds" and sale amounts, sample leaderboard entries, and sample location or dealer features. Unless clearly labeled as real and sourced, this illustrative content does not represent real-time activity of real, identified Buck users, does not represent actual completed transactions by other users, and should not be relied upon as a record of real sales, real prices, real rankings, or real nearby dealers. Names, locations, avatars, flags, and amounts in illustrative content are examples. Do not make purchase, sale, or other decisions based on illustrative content. We may change, replace, or remove illustrative content at any time, and we may later introduce real community features, which would be governed by these Terms and any additional terms presented at that time.

9. Acceptable Use and Prohibited Conduct

You agree to use the App only for lawful purposes and in accordance with these Terms. You agree that you will not, and will not attempt to, and will not allow any third party to:

  • Use the App, any identification, any value estimate, or any output to commit, facilitate, or further any fraud, deception, or other unlawful act, including misrepresenting the identity, authenticity, condition, grade, or value of an item to any buyer, seller, insurer, marketplace, or other party.
  • Use the App to produce, design, facilitate, or assist in the counterfeiting, forging, reproduction, or alteration of any coin, banknote, currency, security, or other instrument, or to evade any counterfeit-deterrence measure. The App is for identification, education, and personal collection tracking only.
  • Reproduce images of currency in any way that violates applicable law, including the reproduction rules of any central bank, treasury, or monetary authority.
  • Reverse engineer, decompile, disassemble, or attempt to derive the source code of the App, except to the limited extent applicable law expressly permits despite this restriction.
  • Copy, modify, distribute, sell, lease, sublicense, or create derivative works of the App or any part of it, or remove or alter any proprietary notices.
  • Interfere with, disrupt, overload, probe, or attempt to gain unauthorized access to the App, our backend, the AI provider, or any related systems or networks, or circumvent any rate limit, security, or access control.
  • Use any automated means (such as bots or scrapers) to access the App, or use the App to build or train a competing product or a machine learning model.
  • Upload or transmit any content that is unlawful, infringing, malicious, or that you do not have the right to submit, or that contains malware.
  • Use the App in violation of any applicable law, regulation, or third-party right, or in any way that could harm us or any other person.

We may investigate and take appropriate action against any suspected violation, including suspending or terminating your access as described in Section 15.

10. Intellectual Property

The App, including its software, design, user interface, text, graphics, logos, icons, the "Buck" name and brand, and all related content (excluding content you provide), and all intellectual property rights in them, are owned by us or our licensors and are protected by copyright, trademark, and other laws. The Terms grant you a license to use the App; they do not transfer any ownership to you. "Buck" and our logos are our trademarks. You may not use them without our prior written permission. All rights not expressly granted are reserved.

Your content: you retain ownership of the images you capture or import. You grant us a limited license to process those images solely to provide the Service to you (for example, to identify the item and, where applicable, estimate value), as described in our Privacy Policy. You represent that you have the rights necessary to submit any image you provide.

The App may contain links to, references to, or information about third-party websites, services, dealers, marketplaces, or listings (for example eBay, dealers, grading services, or auction sites). These are provided for your convenience only. We do not own or control these third parties, we do not endorse them, and we are not responsible for their content, products, services, prices, listings, availability, accuracy, or practices. Any dealings you have with a third party, including any purchase or sale, are solely between you and that third party and are governed by that third party's terms and policies. The App also relies on third-party services, including a third-party AI provider (Google Gemini) and Apple, whose terms and policies apply to their respective parts of your experience. We are not responsible for the acts or omissions of these third parties.

12. Disclaimer of Warranties

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE APP AND ALL CONTENT, IDENTIFICATIONS, VALUE ESTIMATES, AND OTHER OUTPUT ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. WE AND OUR LICENSORS AND SUPPLIERS DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, ACCURACY, AND NON-INFRINGEMENT.

WITHOUT LIMITING THE FOREGOING, WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR FREE OF HARMFUL COMPONENTS, OR THAT ANY IDENTIFICATION OR VALUE ESTIMATE WILL BE ACCURATE, COMPLETE, RELIABLE, CURRENT, OR SUITABLE FOR ANY PURPOSE. ANY MATERIAL OBTAINED THROUGH THE APP IS USED AT YOUR OWN DISCRETION AND RISK.

SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES, SO SOME OF THE ABOVE EXCLUSIONS MAY NOT APPLY TO YOU, IN WHICH CASE THEY APPLY TO THE FULLEST EXTENT PERMITTED BY LAW.

13. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL WE, OR OUR OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, LICENSORS, OR SUPPLIERS, BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR OTHER INTANGIBLE LOSSES, OR FOR ANY LOSS ARISING FROM YOUR RELIANCE ON ANY IDENTIFICATION OR VALUE ESTIMATE OR FROM ANY PURCHASE OR SALE OF ANY ITEM, ARISING OUT OF OR RELATED TO THE APP OR THESE TERMS, WHETHER BASED ON CONTRACT, TORT, NEGLIGENCE, STRICT LIABILITY, OR ANY OTHER THEORY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THE APP OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US, OR PAID THROUGH APPLE FOR THE APP, IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE LIABILITY, OR (B) FIFTY US DOLLARS (USD 50).

SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF CERTAIN DAMAGES, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU. NOTHING IN THESE TERMS LIMITS LIABILITY THAT CANNOT BE LIMITED UNDER APPLICABLE LAW.

14. Indemnification

To the maximum extent permitted by applicable law, you agree to indemnify, defend, and hold harmless us and our officers, directors, employees, agents, licensors, and suppliers from and against any claims, demands, liabilities, damages, losses, and expenses, including reasonable attorneys' fees, arising out of or related to: (a) your use or misuse of the App; (b) your violation of these Terms; (c) your violation of any law or any third-party right, including in connection with any purchase, sale, or representation you make about an item; or (d) any content or image you submit. We reserve the right, at our own expense, to assume the exclusive defense and control of any matter subject to indemnification by you, in which case you agree to cooperate with us.

15. Termination

These Terms remain in effect while you use the App. You may stop using the App at any time and may delete it from your device. We may suspend or terminate your access to the App or any feature at any time, with or without notice, if we reasonably believe you have violated these Terms, if required by law or by Apple, or to protect the App, other users, or third parties.

Termination does not entitle you to any refund, and your Subscription continues to be governed by Apple's billing and cancellation policies described in Section 5. Sections that by their nature should survive termination, including Sections 6, 7, 10, 12, 13, 14, 16, and 18, survive.

16. Governing Law and Dispute Resolution

These Terms and any dispute arising out of or related to them or the App are governed by the laws of Italy, without regard to its conflict-of-laws rules, and you and we submit to the exclusive jurisdiction of the courts located in Italy for any dispute not otherwise subject to a different mandatory forum. Nothing in this Section deprives you of the protection of any mandatory consumer-protection laws of your country of residence, and nothing here limits Apple's rights or the Apple-required terms in Section 18.

17. General

  • Entire agreement: these Terms and the documents they reference (including the Privacy Policy and the Apple terms referenced in Section 18) are the entire agreement between you and us about the App and supersede any prior agreements on that subject.
  • Severability: if any provision is found unenforceable, the remaining provisions stay in effect, and the unenforceable provision is modified to the minimum extent necessary to make it enforceable.
  • No waiver: our failure to enforce any provision is not a waiver of it.
  • Assignment: you may not assign these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, reorganization, or sale of assets.
  • Notices and contact: for questions about these Terms, contact us at support@getbuckapp.com, and for privacy questions contact privacy@getbuckapp.com.

18. Apple-Required Terms (Licensed Application End User License Agreement)

The following terms apply because you obtained the App through the Apple App Store. They reflect Apple's requirements for a Licensed Application End User License Agreement (EULA). To the extent these Terms conflict with Apple's Licensed Application End User License Agreement (the "Apple Standard EULA," available at https://www.apple.com/legal/internet-services/itunes/dev/stdeula/), the Apple Standard EULA governs solely with respect to that conflict, and otherwise these Terms apply.

  1. Acknowledgement. These Terms are concluded between you and us only, and not with Apple. We, not Apple, are solely responsible for the App and its content. The license granted to you for the App in Section 3 is a non-transferable license to use the App on any Apple-branded device that you own or control, and only as permitted by the Usage Rules set out in the Apple Media Services Terms and Conditions, except that the App may be accessed and used by other accounts associated with you through Family Sharing or volume purchasing where applicable.
  2. Scope of License. The license is limited as set out in Section 3 and is governed by these Terms and the Apple Usage Rules.
  3. Maintenance and Support. We, not Apple, are solely responsible for providing any maintenance and support services for the App, as we may specify in these Terms or as required by applicable law. You acknowledge that Apple has no obligation whatsoever to furnish any maintenance and support services for the App. For support, contact support@getbuckapp.com.
  4. Warranty. We are solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for the App to you. To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the App, and any other claims, losses, liabilities, damages, costs, or expenses attributable to any failure to conform to any warranty will be our sole responsibility.
  5. Product Claims. We, not Apple, are responsible for addressing any claims by you or any third party relating to the App or your possession and use of the App, including: (a) product liability claims; (b) any claim that the App fails to conform to any applicable legal or regulatory requirement; and (c) claims arising under consumer protection, privacy, or similar legislation, including in connection with the App's use of any third-party software. These Terms do not limit our liability beyond what is permitted by applicable law.
  6. Intellectual Property Rights. In the event of any third-party claim that the App or your possession and use of the App infringes that third party's intellectual property rights, we, not Apple, will be solely responsible for the investigation, defense, settlement, and discharge of any such intellectual property infringement claim.
  7. Legal Compliance. You represent and warrant that: (a) you are not located in a country that is subject to a US Government embargo, or that has been designated by the US Government as a "terrorist supporting" country; and (b) you are not listed on any US Government list of prohibited or restricted parties.
  8. Developer Name and Address. Any questions, complaints, or claims about the App should be directed to: Emanuele Pio Totaro (developer of record: Emanuele Pio Totaro, Apple Developer Team ID X9RA7Z26V7), based in Italy, and by email at support@getbuckapp.com.
  9. Third-Party Terms of Agreement. You must comply with applicable third-party terms of agreement when using the App.
  10. Third-Party Beneficiary. You and we acknowledge and agree that Apple, and Apple's subsidiaries, are third-party beneficiaries of these Terms, and that, upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary of these Terms.

By using Buck, you acknowledge that you have read and understood these Terms, including the value estimate disclaimer in Section 6, the accuracy and AI disclaimer in Section 7, the subscription terms in Section 5, and the Apple-required terms in Section 18, and that you agree to them.
