LangPlant is operated by Aleksandr Startsev (“Developer”, “I”, or “me”). These Terms of Use (“Terms”) govern your access to and use of the LangPlant mobile application and its related online features (collectively, the “Service”). By installing, accessing, or using any part of the Service, you confirm that you have read, understood, and agree to be bound by these Terms.
The Service is designed as a privacy-first educational application. Certain usage statistics (such as progress, learned words, and in-app performance data) are collected only on your device and remain fully stored locally. I do not have access to this data and it is never transmitted to any server.
The only information sent to the server consists exclusively of:
(i) the text you manually enter as part of language-learning tasks, transmitted without any metadata; and
(ii) the information you voluntarily write and submit through the in-app Report feature. No other data is collected or sent.
I may update or modify these Terms at any time. Updated versions will be made available within the App, and continued use of the Service after such updates become effective constitutes acceptance of the revised Terms. If you do not agree to the Terms or to any future modifications, you must discontinue using the Service.
For any questions regarding these Terms, you can contact me at support@langplant.com.
The Service provides access to language-learning tools, including translation exercises, voice-based practice, grammar analysis, and other educational features designed to support language acquisition. Speech recognition within the App is performed on the device using Apple’s built-in Speech Recognizer. Core learning data and progress are stored locally on your device and remain under your control. Certain text-based inputs may be processed online for evaluation or learning purposes, as described in these Terms.
The Developer may, at any time and at their sole discretion, update, modify, improve, suspend, or discontinue any part of the Service, temporarily or permanently, including specific features, algorithms, content, or online functionality. When possible, changes or disruptions will be implemented through App updates or scheduled server-side maintenance.
You are responsible for your own use of the Service. To maintain a stable, safe, and reliable learning experience, you agree not to misuse, interfere with, or disrupt the Service. This includes, without limitation, attempting to access parts of the Service in an unauthorized manner, modifying or reverse-engineering the App, interfering with its operation, or using it in a way that may damage the Service, its functionality, or its infrastructure.
You may use the Service only for lawful, personal, and educational purposes, and only in accordance with these Terms.
You represent and warrant that your use of the Service will comply with these Terms and with all applicable laws of your jurisdiction. You agree to use the Service only in a lawful and responsible manner.
You are solely responsible for all text you enter into the Service, including any material submitted through the Report feature. By entering or submitting text, you represent and warrant that you have the right to use that material and that your use of it does not violate any rights of third parties or any applicable laws.
You understand and agree that text you provide may be processed for the purpose of operating, improving, and maintaining the Service’s internal algorithms. This processing does not grant the Developer ownership of your text, and none of your submitted text is used directly as content within the Service.
The Service is intended for users aged 6 and older. If parental controls are enabled on the device, certain content-related features may be restricted automatically by the operating system.
Users may enter text into the Service for the purpose of completing language-learning tasks or submitting information through the Report feature (“Submitted Text”). By entering or submitting any Submitted Text, you represent and warrant that you have the lawful right to use and provide such material and that its submission does not violate any applicable laws or infringe upon any third-party rights.
You retain all ownership rights in your Submitted Text. By providing Submitted Text, you grant the Developer a limited, nonexclusive, royalty-free license to process, analyze, and use that material solely for the purposes of operating, maintaining, and improving the internal functionality of the Service, including language evaluation, error detection, and algorithmic refinement. This license is strictly limited to technical processing and does not permit the Developer to publish, display, distribute, or incorporate your Submitted Text into the Service as user-facing content.
Submitted Text is not visible to other users, is not publicly shared, and is not used as training material in a manner that would disclose or reproduce your text within the Service. No part of your Submitted Text will be used to create publicly accessible derivative works or to populate any shared content library.
You acknowledge that, due to the nature of the Service, certain portions of your Submitted Text may be transmitted to remote servers for processing as described in these Terms. No metadata, identifiers, or personal information are transmitted, and the Developer does not retain access to any personal data.
You are solely responsible for your use of the Service. To the extent permitted by applicable law, you agree that the Developer is not responsible or liable for any claims, losses, or damages arising from:
(i) your violation of these Terms;
(ii) your violation of any applicable laws or third-party rights; or
(iii) your submission or use of any text within the Service.
You agree that any consequences resulting from your unlawful, unauthorized, or improper use of the Service are your own responsibility, and you will not hold the Developer liable for such outcomes.
Subject to these Terms, the Developer grants you a personal, non-exclusive, non-transferable license to download, install, and use one copy of the LangPlant mobile application (“the App”) in object code form on a device that you own or control. Except where permitted by applicable law, you may not reverse engineer, decompile, disassemble, modify, or attempt to access the source code of the App or allow any third party to do so.
The App and all related intellectual property rights are owned by the Developer. These Terms grant you no rights in the App other than the limited license described above.
If you obtained the App through the Apple App Store, the following additional terms apply. You acknowledge that these Terms are between you and the Developer only, and not with Apple. Your use of the App must comply with the App Store Terms of Service. Apple has no responsibility for the App or its content and has no obligation to provide any maintenance or support services for the App.
If the App fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price (if any) for the App. To the maximum extent permitted by law, Apple has no other warranty obligations with respect to the App, and any claims, losses, or liabilities relating to the App are governed solely by these Terms.
The Developer, not Apple, is responsible for addressing any claims by you or any third party relating to the App or your possession and use of the App, including:
(i) product liability claims;
(ii) claims that the App fails to comply with any legal or regulatory requirement; and
(iii) claims arising under consumer protection or similar laws.
In the event of any third-party claim that the App infringes that party’s intellectual property rights, the Developer, not Apple, is responsible for handling such claims.
You must comply with any applicable third-party terms of agreement when using the App. You acknowledge and agree that Apple and its subsidiaries are third-party beneficiaries of these Terms as they relate to your license of the App, and that Apple has the right to enforce these Terms against you as a third-party beneficiary.
Certain features of the Service may be offered through an auto-renewing subscription (“Subscription”). If you choose to purchase a Subscription, the payment will be processed by Apple through your Apple ID account. The Subscription will automatically renew at the end of each billing period unless it is canceled at least 24 hours before the renewal date.
You can manage or cancel your Subscription at any time through your Apple ID settings on your device or in the App Store (“Settings” → “Apple ID” → “Subscriptions”). Deleting the App does not cancel your Subscription. Refund requests, where permitted by applicable law or App Store policy, must be directed to Apple.
All charges for Subscriptions, including applicable taxes, are billed by Apple. Prices for Subscriptions may change in the future as determined by Apple or the Developer, and any such changes will be communicated through the App Store according to Apple’s policies. You are responsible for ensuring that your Apple ID payment information is accurate and up to date.
The Developer does not process, store, or have access to your payment information or billing details, and all monetary transactions are handled exclusively by Apple.
All financial transactions related to the Service, including purchases and subscriptions, are processed exclusively through Apple’s in-app purchase system using your Apple ID account. Payments are handled in accordance with Apple’s terms of service, privacy policy, and any applicable App Store payment rules.
The Developer does not process, store, access, or control any payment information, billing details, or transaction data. Any issues related to payment processing, system downtime, refunds, service interruptions, or transaction errors are governed solely by Apple’s policies and must be addressed directly through Apple.
To learn more about Apple’s payment practices, we encourage you to review the terms and policies provided in the App Store.
All purchases and subscriptions made through the Service are processed by Apple using your Apple ID account. The Developer does not process or manage refunds directly. Any requests for refunds, where permitted by applicable law or App Store policy, must be submitted through Apple.
If you cancel a subscription, you will retain access to the paid features until the end of the current billing period. Canceling a subscription does not result in a refund for the current period unless Apple grants one in accordance with its policies.
The Developer does not have access to your payment information and cannot issue refunds or credits of any kind.
The App may provide links to third-party websites, resources, or open-source projects for informational or attribution purposes. These external sites are not owned or controlled by the Developer. The Developer does not endorse and is not responsible for any third-party content, materials, products, or services.
If you choose to access any third-party website or resource, you understand that these Terms and the LangPlant Privacy Policy do not apply to your use of such external services. To the extent permitted by applicable law, the Developer is not liable for any loss or damage arising from your access to or use of third-party websites, software libraries, or resources.
The Service does not display advertisements and does not include any third-party marketing or commercial offers.
The Service is provided to you on an “as is” and “as available” basis. To the fullest extent permitted by applicable law, the Developer makes no representations or warranties of any kind, express or implied, regarding the Service, including but not limited to any warranties of accuracy, reliability, availability, fitness for a particular purpose, non-infringement, or error-free operation.
The Developer does not guarantee that the Service will operate continuously or without interruption, that any content or functionality will be free of errors, or that results obtained through the Service will meet your expectations or produce specific learning outcomes. Certain features of the Service rely on online processing and may be unavailable during maintenance, server updates, technical issues, or other periods of limited connectivity.
Some jurisdictions do not allow the exclusion of certain implied warranties, and in such cases, parts of this section may not apply to you.
To the fullest extent permitted by applicable law, the Developer shall not be liable to you or to any third party for any indirect, incidental, consequential, special, exemplary, or punitive damages arising out of or related to your use of, or inability to use, the Service. This includes, without limitation, damages related to loss of data, inaccurate results, loss of access, interruption of service, or the cost of obtaining substitute services, even if the Developer has been advised of the possibility of such damages.
To the extent permitted by applicable law, the total aggregate liability of the Developer for any claim arising out of or relating to the Service shall not exceed the amount you paid for the Service, if any, during the twelve (12) months preceding the event giving rise to the claim. If you have not made any payments, the Developer’s liability shall be zero.
These limitations form an essential basis of the agreement between you and the Developer, and your use of the Service reflects your acceptance of this allocation of risk.
You may stop using the Service at any time by deleting the App from your device. Because the Service does not use accounts or store personal data on external servers, no further action is required to terminate your use.
The Developer may modify, suspend, or discontinue any part of the Service at any time, including online processing features, where necessary for maintenance, updates, technical changes, or other operational reasons. In such cases, the offline portions of the App already installed on your device may remain available, but certain features may no longer function.
Any sections of these Terms that by their nature should survive termination (including those relating to intellectual property, disclaimers, limitation of liability, indemnification, and governing law) will continue to apply after your use of the Service ends.
All content provided within the Service, including but not limited to the App’s design, user interface elements, text, graphics, images, software, code, audio, algorithms, data structures, educational materials, and their selection and arrangement (“Service Content”), is the proprietary property of the Developer or its licensors. All intellectual property rights in and to the Service Content are reserved.
Except as expressly permitted in these Terms or by applicable law, you may not copy, modify, reproduce, republish, distribute, translate, display, transmit, sell, sublicense, or create derivative works from any portion of the Service Content. You may not use scraping tools, data mining, automated scripts, or similar technologies to access, extract, or collect any Service Content.
Nothing in these Terms grants you any rights to the Service Content other than the limited license to use the App as described herein.
You retain ownership of any text you enter into the Service (“Submitted Text”). The Developer does not claim ownership of your Submitted Text. By submitting text, you grant the Developer a limited, nonexclusive license to process that material solely for the purposes of operating, maintaining, and improving the internal functionality of the Service. This license does not permit the Developer to publish, distribute, or reuse your Submitted Text as content visible to other users.
Any data, performance metrics, or learning statistics generated locally on your device from your use of the Service (“Activity Data”) remain stored on your device and are not accessible to the Developer. Such Activity Data is used only by the App to support your personal learning experience.
All rights not expressly granted to you in these Terms are reserved by the Developer and its licensors.
“LangPlant,” the LangPlant logo, and all other names, graphics, and marks used within the Service are trademarks or proprietary identifiers of the Developer. All other trademarks, service marks, graphics, and logos appearing in the Service are the property of their respective owners.
Your access to and use of the Service does not grant you any right or license to use the Developer’s trademarks or any third-party trademarks displayed within the App, except as expressly permitted by applicable law.
Use of the Service is also governed by the LangPlant Privacy Policy, available at langplant.com/privacy. By using the Service, you acknowledge and agree that you have read the Privacy Policy and consent to its terms.
The Service does not allow users to upload or publish copyrighted materials. Some visual content in the App, including film or series posters, is provided through the TMDB API. Such materials remain the property of their respective copyright holders and are used in accordance with the TMDB API terms. LangPlant is not affiliated with TMDB.

These Terms shall be governed by and interpreted in accordance with the laws of the jurisdiction in which you reside, without regard to conflict-of-law principles. Your use of the Service may also be subject to other local, national, or international laws that apply to you.
Unless otherwise required by applicable law, any legal proceedings arising out of or relating to these Terms or your use of the Service shall be resolved in the courts of the jurisdiction in which you reside. Nothing in these Terms restricts any rights you may have under the laws of your local jurisdiction.
If you have any questions or concerns regarding the Service or these Terms, you agree to first contact the Developer at support@langplant.com to allow an opportunity to resolve the issue informally.
If a dispute cannot be resolved informally, and unless otherwise required by applicable law, any legal claim arising out of or relating to these Terms or your use of the Service shall be resolved in the courts of the jurisdiction in which you reside, as described in the “Choice of Forum” section above.
To the extent permitted by applicable law, disputes must be brought on an individual basis and not as part of any class, collective, or representative action.
Nothing in these Terms prevents either party from seeking temporary or urgent relief from a court where such relief is available under applicable law.
These Terms are provided in English. No other language versions are currently available.
These Terms constitute the entire agreement between you and the Developer regarding your use of the Service. If any provision of these Terms is found to be invalid or unenforceable by a court of competent jurisdiction, that provision will be applied only to the extent permitted by law, and the remaining provisions will continue in full force and effect.
A failure by the Developer to enforce any right or provision of these Terms shall not constitute a waiver of that right or provision, nor of any future enforcement.
You may not assign or transfer your rights or obligations under these Terms without prior written permission from the Developer. The Developer may update or transfer its rights and obligations under these Terms in connection with changes to the Service or its operation, provided such changes do not materially affect your rights under these Terms.
