Terms of Service

Last updated: October 2, 2026

From everyone at GoodUI, thank you for using our products! We build them to help you do your best work. Because we don't know every one of our customers personally, we have to put in place some Terms of Service to help keep the ship afloat.

When we say “Company”, “we”, “our”, or “us” in this document, we are referring to Linowski Interaction Design, Inc. We launched GoodUI.org.

When we say “Services”, we mean any product created and maintained by Linowski Interaction Design, Inc. That includes GoodUI.

When we say “You” or “your”, we are referring to the people or organizations that own an account with one or more of our Services. Sections that say so, such as Data Use, Scraping, and AI Training, also apply to anyone accessing our Services without an account.

We may update these Terms of Service in the future.

When you use our Services, now or in the future, you are agreeing to the latest Terms of Service. That's true for any of our existing and future products and all features that we add to our Services over time. There may be times where we do not exercise or enforce any right or provision of the Terms of Service; in doing so, we are not waiving that right or provision. These terms do contain a limitation of our liability.

Account Terms

  1. You are responsible for maintaining the security of your account and password. The Company cannot and will not be liable for any loss or damage from your failure to comply with this security obligation.
  2. You may not use the Services for any purpose such as:
    • Violence, or threats thereof: If an activity qualifies as violent crime in Canada or where you live, you may not use GoodUI products.
    • Child exploitation, sexualization, or abuse: We don’t tolerate any activities that create, disseminate, or otherwise cause child abuse.
    • Hate speech: You cannot use our products to advocate for the extermination, domination, or oppression of people.
    • Harassment: Intimidating or targeting people or groups through repeated communication, including using racial slurs or dehumanizing language, is not welcome.
    • Doxing: If you are using our products to share other peoples’ private personal information for the purposes of harassment, we don’t want anything to do with you.
    • Malware or spyware: Code for good, not evil. If you are using our products to make or distribute anything that qualifies as malware or spyware — including remote user surveillance — begone.
    • Phishing or otherwise attempting fraud: It is not okay to lie about who you are or who you affiliate with to steal from, extort, or otherwise harm others.
    • Spamming: No one wants unsolicited commercial emails. We don’t tolerate folks (including their bots) using our products for spamming purposes. If your emails don’t pass muster with CAN-SPAM or any other anti-spam law, it’s not allowed.
    • Cybersquatting: We don’t like username extortionists. If you purchase a product account in someone else’s name and then try to sell that account to them, you are cybersquatting. Cybersquatting accounts are subject to immediate cancellation.
    • Infringing on intellectual property: You can’t use our products to make or disseminate work that uses the intellectual property of others beyond the bounds of fair use.
  3. You are responsible for all content posted and activity that occurs under your account. That includes content posted by others who either: (a) have access to your login credentials; or (b) have their own logins under your account.
  4. You must be a human. Accounts registered by “bots” or other automated methods are not permitted.
  5. If you violate any of the terms, we may terminate your account.

Payment, Refunds, and Plan Changes

  1. If you are using a free version of one of our Services, it is really free: we do not ask you for your credit card and — just like for customers who pay for our Services — we do not sell your data.
  2. If you are upgrading from a free plan to a paid plan, we will charge your card immediately and your billing cycle starts on the day of upgrade. For other upgrades or downgrades in plan level, the new rate starts from the next billing cycle.
  3. All fees are exclusive of all taxes, levies, or duties imposed by taxing authorities. Where required, we will collect those taxes on behalf of the taxing authority and remit those taxes to taxing authorities. Otherwise, you are responsible for payment of all taxes, levies, or duties.
  4. Paid plans renew automatically at the end of each billing period (monthly or yearly) at the then-current rate, unless you cancel before the renewal date. You can cancel at any time from the member dashboard; your access continues until the end of the period you have already paid for.
  5. Refunds
    • Given that this is an information based service, payments are non-refundable, except under our Results Guarantee.
    • Results Guarantee: If you A/B test a GoodUI pattern and it doesn't get you the results you're happy with, contact us with your experiment within 30 days of your first payment and we will refund 100% of that payment. The Results Guarantee applies only to the first payment of a monthly plan. It does not apply to yearly plans or to renewal payments.

Cancellation and Termination

  1. You are solely responsible for properly canceling your account. You may cancel your account from within the member dashboard, or you may contact us and we will cancel it for you.
  2. We have the right to suspend or terminate your account and refuse any and all current or future use of our Services for any reason at any time. Suspension means you and any other users on your account will not be able to access the account or any content in the account. Termination will furthermore result in the deletion of your account or your access to your account, and the forfeiture and relinquishment of all content in your account. We also reserve the right to refuse the use of the Services to anyone for any reason at any time. We have this clause because there are some things we staunchly stand against and this clause is how we exercise that stance.
  3. Verbal, physical, written or other abuse (including threats of abuse or retribution) of Company employee or officer will result in immediate account termination.

Modifications to the Service and Prices

  1. We work hard to support our Services and keep them secure. Sometimes it becomes technically impossible to continue a feature or we redesign a part of our Services because we think it could be better or we decide to close new signups of a product. We reserve the right at any time to modify or discontinue, temporarily or permanently, any part of our Services with or without notice.
  2. Sometimes we change the pricing structure for our products. When we do that, we tend to exempt existing customers from those changes. However, we may choose to change the prices for existing customers. If we do so, we will give at least 30 days notice and will notify you via the email address on record. We may also post a notice about changes on our websites or the affected Services themselves.

Uptime, Security, and Privacy

  1. Your use of the Services is at your sole risk. We provide these Services on an “as is” and “as available” basis. We do not offer service-level agreements for most of our Services.
  2. We use third party vendors and hosting partners to provide the necessary hardware, software, networking, storage, and related technology required to run the Services.
  3. We collect only the information needed to run the Services, such as your name, email address, and billing details (payments are processed by our payment providers). We do not sell this information, and we do not retain, use, or disclose it for any other commercial purposes unless we have your explicit permission.

Copyright and Content Ownership

  1. All content posted on the Services must comply with Canadian copyright law.
  2. We claim no ownership over the material you provide to the Services. All materials uploaded remain yours. When you contribute A/B test results or other material for publication on GoodUI, you grant the Company a worldwide, non-exclusive, perpetual, royalty-free license to use, publish, adapt, and include that material in the GoodUI Data, including in licenses the Company grants to others. Any additional permissions agreed in writing at the time of contribution (such as anonymization) will be respected.
  3. We do not pre-screen content, but reserve the right (but not the obligation) in our sole discretion to refuse or remove any content that is available via the Service.
  4. The names, look, and feel of the Services are copyright© to the Company. All rights reserved. You may not duplicate, copy, or reuse any portion of the HTML, CSS, JavaScript, or visual design elements without express written permission from the Company. You must request permission to use the Company's logo or any Service logos for promotional purposes.
  5. You agree not to reproduce, duplicate, copy, sell, resell or exploit any portion of the Services, use of the Services, or access to the Services without the express written permission by the Company.
  6. You must not modify another website so as to falsely imply that it is associated with the Services or the Company.
  7. Your membership grants a non-exclusive, non-transferable license, for the number of users included in your plan, to access and reference GoodUI data, patterns, and A/B test results for internal use within your organization. All other uses require a separate written license from the Company.

Data Use, Scraping, and AI Training

  1. GoodUI's patterns, A/B test results, metrics, analyses, and the collection as a whole (the “GoodUI Data”) are the result of substantial investment by the Company and are protected by copyright and other rights.
  2. Unless you have a separate written license agreement with the Company, you may not, whether or not you have an account:
    • use any automated means (including bots, scrapers, crawlers, or scripts) to access, collect, or download GoodUI Data;
    • use GoodUI Data, in whole or in part, to train, fine-tune, evaluate, benchmark, or ground (including through retrieval or embeddings) any artificial intelligence or machine learning model;
    • include GoodUI Data in any dataset, database, product, or service made available to third parties;
    • share account access or GoodUI Data with anyone outside the users included in your plan.
  3. The Company expressly reserves all rights to text and data mining of the Services and GoodUI Data, including under Article 4 of EU Directive 2019/790.
  4. Licenses for data integration, AI training, and other uses are available. Please contact us.
  5. Breach of this section may result in immediate account termination without refund, and the Company may seek any other remedies available under law.

Expert Reviews

  1. Plans that include A/B test reviews entitle you to the number of reviews stated in your plan.
  2. Experiments, data, and other materials you share with us for a review are kept confidential. We use them only to prepare your review and will not publish them without your written permission.
  3. Reviews are advisory. Decisions about your experiments, products, and business remain yours.

Features and Bugs

We design our Services with care, based on our own experience and the experiences of customers who share their time and feedback. However, there is no such thing as a service that pleases everybody. We make no guarantees that our Services will meet your specific requirements or expectations.

GoodUI Data describes the results of past experiments. Past results do not guarantee future results, and any pattern may perform differently in your context. Apart from the Results Guarantee described above, we do not guarantee any particular outcome from using the Services.

We also test all of our features extensively before shipping them. As with any software, our Services inevitably have some bugs. We track the bugs reported to us and work through priority ones, especially any related to security or privacy. Not all reported bugs will get fixed and we don't guarantee completely error-free Services.

Liability

We mention liability throughout these Terms but to put it all in one section:

You expressly understand and agree that the Company shall not be liable, in law or in equity, to you or to any third party for any direct, indirect, incidental, lost profits, special, consequential, punitive or exemplary damages, including, but not limited to, damages for loss of profits, goodwill, use, data or other intangible losses (even if the Company has been advised of the possibility of such damages), resulting from: (i) the use or the inability to use the Services; (ii) the cost of procurement of substitute goods and services resulting from any goods, data, information or services purchased or obtained or messages received or transactions entered into through or from the Services; (iii) unauthorized access to or alteration of your transmissions or data; (iv) statements or conduct of any third party on the service; (v) or any other matter relating to this Terms of Service or the Services, whether as a breach of contract, tort (including negligence whether active or passive), or any other theory of liability.

Where liability cannot be excluded under applicable law, the Company's total liability to you for any claim relating to the Services is limited to the amount you paid the Company in the 12 months before the claim arose.

Governing Law

These Terms of Service are governed by the laws of the Province of Ontario and the federal laws of Canada applicable there. Any dispute relating to these Terms or the Services will be resolved in the courts of Ontario, Canada.
