Terms & Conditions
These terms and conditions apply to the PolyPotion app for web browsers, together with any related services operated by Matvei Pavlov (collectively, the “Application”). Matvei Pavlov is referred to here as the “Service Provider”. By accessing or using the Application, you agree to these Terms and Conditions. Please read them carefully before using the Application.
In plain termsPolyPotion is free to use and its source is publicly viewable. You’re welcome to read it, learn from it, and use the app. You may not copy, redistribute, host, fork, or build a competing or commercial product from it — see Source availability below.
§1License to use the Application
Subject to your compliance with these Terms, the Service Provider grants you a limited, non-exclusive, non-transferable, revocable license to access and use the Application on a device for personal or internal business purposes. You may not reproduce, distribute, modify, create derivative works from, reverse engineer, decompile, or disassemble the Application, except as and only to the extent that such activity is expressly permitted by applicable law.
§2Source availability & no cloning
The Application’s source code may be made publicly viewable for the purposes of transparency, security review, and learning. Making the source viewable does not make the Application “open source” and grants you no license to reuse it. No right or license is granted, whether by these Terms, by implication, or by making the source visible, to:
- Copy, download, mirror, host, or redistribute the Application or its source code, in whole or in part;
- Fork, clone, adapt, or create derivative or competing works based on the Application or its source code;
- Sell, license, sublicense, monetize, or otherwise commercially exploit the Application, its source code, or anything derived from it;
- Remove, alter, or obscure any copyright, trademark, authorship, or proprietary notices.
Any attempt to extract the source code beyond what is made viewable, translate the Application into other languages, or create derivative versions is not permitted. All rights not expressly granted are reserved by the Service Provider.
If you wish to reuse any part of the Application — including for a non-commercial project — you must obtain written permission from the Service Provider first at mat.github.vei@gmail.com.
§3Intellectual property
The Service Provider retains all intellectual property rights in the Application, including its code, design, trademarks, service marks, trade names, logos, and branding (the “IP”). Nothing in these Terms grants you any license or right to use the Service Provider’s trademarks, logos, or branding for any purpose. You agree not to remove, alter, or obscure any copyright, trademark, or other proprietary notices displayed in or on the Application. All trademarks, copyrights, database rights, and other intellectual property rights related to the Application remain the property of the Service Provider.
§4Termination
The Service Provider may suspend your access to the Application if you materially breach these Terms. The Service Provider will provide you with written notice of the breach and, where the breach is capable of cure, you will have 14 days from receipt of notice to remedy it. If you fail to cure the breach within that period, the Service Provider may terminate your access.
The Service Provider may suspend or terminate your access immediately without notice if you violate applicable law, infringe intellectual property rights, or engage in activity that could cause harm to other users or the Service Provider. Upon termination, your right to use the Application will end and you must cease all use.
By accessing and using this Application, you represent that you are legally permitted to use it in your jurisdiction. You must be at least 16 years of age (the age of digital consent in your jurisdiction) to use the Application. If you are below 16, a parent or legal guardian must review and accept these Terms on your behalf.
§5User-generated content & acceptable use
If this Application allows users to post, share, or upload content, you agree not to post content that:
- Is illegal or violates third-party intellectual property rights (copyright, trademark, patents);
- Is abusive, threatening, harassing, defamatory, or hate speech;
- Contains discrimination or incitement to violence or illegal activity;
- Is spam, phishing, or contains malware;
- Violates the privacy or personal data rights of others;
- Is misleading, false, or deceptive;
- Contains explicit violence or sexual content (unless age-gated appropriately).
The Service Provider reserves the right to remove or disable access to content that violates these guidelines, suspend or terminate accounts of repeat violators, cooperate with law enforcement where illegal content is reported, and moderate, filter, or hide content that violates these Terms or applicable law. Content submitted through the Application may be visible to other users or the public, depending on how the Application functions.
If you believe content violates these Terms, infringes your rights, or is unlawful, you may report it to the Service Provider at mat.github.vei@gmail.com. Your report should include enough information for the Service Provider to identify the content, evaluate the complaint, and contact you if follow-up is required. Where the Application provides such features, you may also report content, block users, or mute notifications directly through the interface; the Service Provider reviews in-app reports with the same standards described here.
The Service Provider may review reported content, request additional information, remove or restrict access to content, and take action against the responsible account where appropriate. Users affected by moderation decisions may contact the Service Provider to request further review; the Service Provider will respond within a reasonable period and provide reasons for any upheld decision, subject to applicable law.
By submitting user-generated content you grant the Service Provider a non-exclusive, worldwide, royalty-free license to use, reproduce, distribute, prepare derivative works of, display, and perform the content in connection with the Application and the Service Provider’s business. This license does not grant the Service Provider the right to sell or sublicense your content to third parties independently of the Application. You represent and warrant that you own or control all rights in the content you post and that its use does not violate these Terms or applicable law. Your content may include personal data; processing of such data is governed by the Privacy Policy. Do not post personal data of others without their consent.
§6Service, updates & your responsibilities
The Service Provider is dedicated to keeping the Application beneficial and efficient. As such, they reserve the right to modify the Application or charge for their services at any time and for any reason; any charges will be clearly communicated to you beforehand.
The Application processes data that you provide within your browser in order to provide the Service. It is your responsibility to maintain the security of your device and browser. Avoid using the Application on a compromised device or through modified or insecure software, as this could expose you to malware and may result in the Application not functioning correctly.
The Service Provider does not assume responsibility for every aspect of your use. Some functions require an active internet connection, and the Service Provider cannot be held responsible if the Application does not function fully due to lack of internet access. Your internet service provider’s terms still apply, and you may incur data charges from your provider; you accept responsibility for any such charges. Likewise, it is your responsibility to keep your device powered and operational.
The Service Provider may update the Application from time to time; updates are deployed to the website automatically, and the Service Provider may cease to support older versions or discontinue the Application at any time without prior notice. Upon any discontinuation, the rights and licenses granted to you under these Terms will end and you must cease using the Application. The Service Provider accepts no liability for any loss you experience as a result of relying entirely on third-party information provided through the Application, or for inaccuracies in third-party content.
Nothing in these Terms shall limit any rights you have under applicable consumer protection laws that cannot be lawfully excluded.
§7Limitation of liability
To the fullest extent permitted by law, the Service Provider shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to lost profits, data loss, or business interruption, even if advised of the possibility of such damages.
However, the Service Provider retains full liability for:
- Death or personal injury caused by negligence;
- Fraud or fraudulent misrepresentation;
- Any other liability that cannot be excluded or limited under applicable law.
To the fullest extent permitted by law, the total liability of the Service Provider for any claim shall not exceed the amount paid by you to the Service Provider for the Application in the 12 months preceding the claim, or the minimum amount that must be paid under applicable law, whichever is greater. Because the Application is provided free of charge, this means the Service Provider’s liability is limited to the minimum amount permitted by applicable law.
§8Indemnification
To the fullest extent permitted by law, you agree to indemnify and hold harmless the Service Provider, its affiliates, officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, and expenses, including reasonable legal fees, arising out of or directly related to your breach of these Terms or your intentional misuse of the Application, including user-generated content you submit in violation of these Terms.
This indemnification does not apply to claims arising from the Service Provider’s own negligence, breach of these Terms, or violation of applicable law. In jurisdictions where consumer indemnification is restricted by law, this clause shall be limited to the maximum extent permitted.
§9Governing law & jurisdiction
These Terms and Conditions are governed by the laws of the jurisdiction in which the Service Provider is established, excluding conflict-of-law rules, except to the extent mandatory consumer protection laws provide otherwise. Any dispute arising out of or relating to these Terms will be brought before the courts that have jurisdiction under applicable law. Nothing in this clause limits any rights you may have to bring a claim in a court that is competent under mandatory law.
§10DSA compliance (Digital Services Act)
If the Application is an intermediary service as defined under the Digital Services Act (Regulation (EU) 2022/2065, “DSA”), the following provisions apply in addition to the terms above.
Point of contact. The Service Provider maintains a single point of contact for direct communication with EU authorities and recipients of the service, reachable at mat.github.vei@gmail.com. Where the Service Provider is established outside the European Union, a legal representative in the EU has been designated in accordance with Article 13 of the DSA.
Content moderation and statement of reasons. When the Service Provider restricts access to content, suspends or terminates an account, or otherwise limits the availability of features, a clear and specific statement of reasons will be provided to the affected user, including the nature of the restriction, its legal or contractual basis, and available redress mechanisms, in accordance with Article 17 of the DSA.
Notice and action. Users and third parties may submit notices of allegedly illegal content through the contact details in these Terms. Notices will be processed promptly and diligently, without automated decision-making where circumstances require human review, acknowledged electronically, and a decision communicated without undue delay, in accordance with Article 16 of the DSA.
Out-of-court dispute settlement. Disputes regarding content moderation decisions may be submitted to an out-of-court dispute settlement body certified under Article 21 of the DSA. The Service Provider will engage with such bodies in good faith. Use of out-of-court dispute settlement does not affect your right to seek a judicial remedy under applicable law.
Transparency reporting. The Service Provider publishes periodic transparency reports covering content moderation activities, including the volume of notices received, actions taken, and automated means used, in accordance with Article 24 of the DSA. Reports are available upon request at mat.github.vei@gmail.com. These DSA provisions apply only to the extent the Application qualifies as an intermediary service under the DSA and do not replace or limit any rights or obligations under applicable consumer protection or data protection law.
§11Severability & entire agreement
If any provision of these Terms is held to be invalid, illegal, or unenforceable by a court of competent jurisdiction, that provision shall be modified to the minimum extent necessary to make it valid and enforceable, and the remaining provisions shall remain in full force and effect.
These Terms and Conditions, together with the Privacy Policy, constitute the entire agreement between you and the Service Provider concerning your use of the Application, superseding any prior agreements or understandings.
§12Changes & contact
The Service Provider may periodically update these Terms and Conditions, so you are advised to review this page regularly. Changes will be notified by posting the new Terms on this page. Previous versions will be maintained and made available upon request by contacting mat.github.vei@gmail.com.
If you have any questions or suggestions about these Terms and Conditions, please contact the Service Provider at mat.github.vei@gmail.com.
