Effective date: July 16, 2026
Please read these Terms of Use ("Terms") carefully. By installing, accessing, or using HearthCardCheck ("the App"), you agree to be bound by these Terms. If you do not agree, do not install or use the App. The App is published by Pro Numerology / Hearth Software ("we", "us", "our").
PLEASE READ CAREFULLY. The App tests whether a memory card or USB drive is genuine or counterfeit, and its results are best-effort, not a guarantee. The App also offers an optional Repair feature that erases the entire card, only at your explicit request and at your own risk. These Terms disclaim warranties, limit and cap our liability, place full responsibility for how you use the App on you, and require you to indemnify us in certain cases. They apply to the maximum extent permitted by the law that applies to you, and they survive after you stop using the App.
Subject to these Terms and to your payment where the App is sold, we grant you a personal, limited, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use the App on devices you own or control, for your personal or internal purposes. Your use is also subject to the rules of the store through which you obtained the App (for example, the Microsoft Store Standard Application License Terms), which apply in addition to these Terms. The App is licensed, not sold. You must be of legal age to form a binding contract in your jurisdiction to use the App. Purchases, refunds, and cancellations for copies obtained through a store are handled by that store under its own terms and policies; to the maximum extent permitted by applicable law, we do not provide refunds directly.
The App, including all software, design, text, graphics, icons, and trademarks, is owned by us or our licensors and is protected by intellectual-property laws. These Terms grant you a license to use the App; they do not transfer any ownership to you. All rights not expressly granted are reserved. The names "HearthCardCheck", "Hearth", and related logos are our marks. Except to the extent this restriction is prohibited by applicable law, you agree not to: (a) copy, modify, or create derivative works of the App; (b) reverse engineer, decompile, or disassemble the App, or attempt to derive its source code; (c) rent, lease, lend, sell, redistribute, or sublicense the App; (d) remove or alter any proprietary notices; (e) use the App to develop a competing product; (f) bypass, disable, or tamper with any security or technical-protection feature of the App; or (g) use the App in any unlawful manner.
The App tests a memory card or USB drive by writing a verifiable pattern into free space and reading it back, in order to estimate how much of the card stores data reliably and whether the card is counterfeit. Its results are best-effort indications, not a guarantee. A quick or partial check only tests part of the card, so a card that passes a partial check may still be defective or counterfeit beyond the tested region; a full check is more thorough but still cannot predict future failures. A card can also be intermittently faulty, fail over time, or behave differently under heat, wear, or with different readers and devices. The reported "real" or "reliable" capacity is an estimate based on what read back correctly at the time of the test.
The App is a consumer software tool. It is not a professional testing, forensic, or certification service, and nothing shown by the App (including verdicts, capacity estimates, and explanations) is professional, technical, or legal advice. Do not rely on the App as the sole basis for storing irreplaceable data; always keep independent backups of anything important.
If a card is found to be counterfeit, the App offers an optional, clearly labeled Repair feature that creates a single partition spanning only the card's measured real capacity, so that the operating system no longer writes to the counterfeit region. This feature erases the entire card: every file and partition on it is permanently destroyed. The Repair runs Windows' own disk-partitioning tool and therefore requires Administrator permission (Windows will prompt you). The App explains what it will do, shows you the exact steps it will run, and proceeds only at your explicit request and after you confirm. You are solely responsible for the decision to repair a card and for all of its effects, including the loss of everything on the card, and to the maximum extent permitted by applicable law we accept no liability for those effects. Repair relies on the App's capacity estimate, which is best-effort; a card that is genuinely failing, rather than simply counterfeit, may remain unreliable or unusable even after repair, and no particular outcome, capacity, or future reliability is guaranteed. Back up anything you still want first, keep the card connected until the Repair finishes, and if you use a device you do not own or administer, obtain permission before running it.
You agree to use the App only for lawful purposes. You will not use the App on cards or drives you are not authorized to use, to circumvent security or access controls, to violate any person's rights or privacy, or in connection with any unlawful, fraudulent, or harmful activity.
To the maximum extent permitted by law, we are not responsible for any loss, corruption, deletion, or unavailability of files or data, however caused, including data lost when you choose to Repair (erase) a card, data lost because a card was counterfeit or failing, data affected by writing test data to a card, a card that fails during or after testing, or the behavior of Windows, drivers, disks, memory cards, card readers, or third-party software. Keep independent backups of anything important.
Install HearthCardCheck only from our official page or the Microsoft Store. Because the Repair feature runs with Administrator permission and can erase a disk, a tampered or "cracked" copy is especially dangerous: people who pirate this kind of app often hide malware or ransomware inside it. A copy obtained from anywhere other than our official channels is not covered by these Terms or by any responsibility on our part, and installing it is entirely at your own risk.
The App runs on Microsoft Windows and relies on your disks, drivers, file systems, card readers, and other components we do not provide or control; we are not responsible for those components or for any act, omission, failure, or change in them. Links opened from the App (for example to the Microsoft Store or our websites) lead to services governed by their own terms and policies.
We may update, change, suspend, or discontinue the App or any of its features at any time, with or without notice, and we are under no obligation to provide updates or support. The in-app "More from Hearth" suggestions are informational and may change or be unavailable.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE", WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. WE 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. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE; THAT ANY VERDICT OR CAPACITY ESTIMATE WILL BE ACCURATE; THAT A CARD FOUND GENUINE WILL NOT LATER FAIL; THAT A REPAIRED CARD WILL BE RELIABLE OR REACH ANY PARTICULAR CAPACITY; OR THAT TESTING OR REPAIR WILL BE FREE OF ADVERSE EFFECTS. YOU USE THE APP AT YOUR OWN RISK.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL WE (OR OUR OWNERS, EMPLOYEES, OR LICENSORS) BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, FILES, PROFITS, REVENUE, GOODWILL, OR BUSINESS, ARISING OUT OF OR RELATED TO YOUR USE OF OR INABILITY TO USE THE APP, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, AND REGARDLESS OF THE THEORY OF LIABILITY.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THE APP OR THESE TERMS WILL NOT EXCEED THE GREATER OF (a) THE AMOUNT YOU ACTUALLY PAID US OR THE STORE FOR THE APP IN THE TWELVE MONTHS BEFORE THE CLAIM, OR (b) TEN US DOLLARS (USD 10). YOU ACKNOWLEDGE THAT THIS ALLOCATION OF RISK IS REASONABLE GIVEN THE ONE-TIME PRICE OF THE APP.
To the maximum extent permitted by law, you agree to indemnify, defend, and hold harmless us and our owners, employees, and licensors from and against any claims, damages, liabilities, losses, and expenses (including reasonable legal fees) arising out of or related to your use or misuse of the App, the cards or drives you test or repair, your violation of these Terms, or your violation of any law or the rights of any third party.
These Terms apply until terminated. Your license terminates automatically if you breach these Terms. Upon termination you must stop using the App and delete all copies. Sections that by their nature should survive (including Ownership, Disclaimers, Limitation of Liability, Indemnification, and Governing Law) survive termination.
You represent that you are not located in, and will not use or export the App in violation of, any applicable export-control or sanctions laws, and that you are not on any restricted-party list under such laws. You will comply with all laws applicable to your use of the App.
These Terms are governed by the laws of the State of Israel, without regard to its conflict-of-laws rules. The competent courts located in Tel Aviv-Yafo, Israel, will have exclusive jurisdiction over any dispute arising out of or relating to the App or these Terms, and you consent to their jurisdiction, except where applicable mandatory consumer-protection law provides otherwise.
Some jurisdictions do not allow the exclusion of certain warranties or the exclusion or limitation of certain damages. To that extent, some of the exclusions and limitations above may not apply to you, and you may have additional rights under the mandatory law of your place of residence. Nothing in these Terms limits rights that cannot be limited under applicable law.
These Terms, together with the Privacy Policy and any store license terms, are the entire agreement between you and us regarding the App and supersede any prior agreements. If any provision is found unenforceable, the remaining provisions remain in effect, and the unenforceable provision will be enforced to the maximum extent permissible. Our failure to enforce any provision is not a waiver. You may not assign these Terms; we may assign them in connection with a merger, acquisition, or sale of assets. Section headings are for convenience only.
We may revise these Terms from time to time. When we do, we will update the effective date and post the revised Terms at this URL. Your continued use of the App after the revised Terms take effect constitutes acceptance; if you do not agree, stop using and uninstall the App.
If you choose to send us suggestions, ideas, bug reports, or other feedback about the App, you grant us a perpetual, irrevocable, worldwide, transferable, royalty-free right to use, modify, and incorporate that feedback for any purpose, without any obligation, attribution, or compensation to you, and we are equally free not to use it.
The App is a consumer application intended for ordinary home use. It is not designed, tested, certified, or licensed for use in any high-risk or safety-critical environment or activity, including medical or life-support systems, emergency services, aviation, nuclear facilities, or any other setting in which a failure, error, or delay of the App could lead to death, personal injury, or severe physical, property, or environmental damage. You must not use the App in any such environment, and, to the maximum extent permitted by applicable law, we accept no responsibility or liability for any such use.
To the maximum extent permitted by applicable law, any claim arising out of or relating to the App or these Terms must be brought within twelve (12) months after the event giving rise to the claim first occurred; otherwise, the claim is permanently barred. Where the law that applies to you does not permit such a limitation, the shortest limitation period that it does permit applies instead.
These Terms were drafted in English. Translations, including the German version, are provided for convenience only. To the extent permitted by applicable law, if there is any inconsistency between the English version and a translation, the English version prevails.
These Terms are between you and us only, and create no rights for, and may not be enforced by, any other person. Microsoft and other platform, store, or component providers are not parties to these Terms and owe you no obligations under them. We will not be liable for any failure or delay caused by circumstances beyond our reasonable control.
