Terms of Service

Last updated: June 10, 2025

From everyone at Contamos Labs, thank you for using our products! We build them to help you learn languages in what we think is the best way. 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.

We may update these Terms of Service ("Terms") in the future. Typically these changes have been to clarify some of these terms by linking to an expanded related policy. Whenever we make a significant change to our policies, we will refresh the date at the top of this page and take any other appropriate steps to notify account holders.

When you use our Services, now or in the future, you are agreeing to the latest Terms. There may be times where we do not exercise or enforce a right or provision of the Terms; however, that does not mean we are waiving that right or provision. These Terms do contain a limitation of our liability.

If you violate any of the Terms, we may terminate your account.

Definitions

When we say "Company", "Company Properties", "we", "our", or "us" in this document, we are referring to Contamos Labs.

When we say "Services", we mean our websites, including contamos.app, and any product created and maintained by Contamos Labs. That includes Basecamp (all versions), whether delivered within a web browser, desktop application, mobile application, or another format.

When we say "You" or "your", we mean the individual accessing or using the Service, or the company, or other legal entity on behalf of which such individual is accessing or using the Service, as applicable.

Account Terms

  1. You are responsible for maintaining the security of your account. The Company cannot and will not be liable for any loss or damage from your failure to comply with this security obligation.
  2. You must be a human. Accounts registered by "bots" or other automated methods are not permitted.

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. You shall provide the Company with accurate and complete billing information including full name, address, state, zip code, telephone number, and a valid payment method information. Should automatic billing fail to occur for any reason, the Company will issue an electronic invoice indicating that you must proceed manually, within a certain deadline date, with the full payment corresponding to the billing period as indicated on the invoice.
  3. For paid Services that offer a free trial, we explain the length of trial when you sign up. After the trial period, you need to pay in advance to keep using the Service. If you do not pay, we will freeze your account and it will be inaccessible until you make payment. If your account has been frozen for a while, we will queue it up for auto-cancellation.
  4. 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.
  5. 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.
  6. You will not receive a refund for the fees you already paid for your current subscription period and you will be able to access the Service until the end of your current subscription period.

Cancellation and Termination

  1. All of your content will be inaccessible from the Services immediately upon account cancellation. Within 30 days, all content will be permanently deleted from active systems and logs. Within 60 days, all content will be permanently deleted from our backups. We cannot recover this information once it has been permanently deleted.
  2. If you cancel the Service before the end of your current paid up month, your cancellation will take effect immediately, and you will not be charged again. We do not automatically prorate unused time in the last billing cycle.
  3. 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 statistically speaking, out of the hundreds of thousands of accounts on our Services, there is at least one doing something nefarious. There are some things we staunchly stand against and this clause is how we exercise that stance.
  4. Verbal, physical, written or other abuse (including threats of abuse or retribution) of a Company employee or officer will result in immediate account termination.

Modifications to the Service and Prices

  1. We are committed to our customers to support our Services. That means when it comes to security, privacy, and customer support, we will continue to maintain any legacy Services. 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 our Services — but do take uptime of our applications seriously.
  2. We reserve the right to temporarily disable your account if your usage significantly exceeds the average usage of other customers of the Services. Of course, we'll reach out to the account owner before taking any action except in rare cases where the level of use may negatively impact the performance of the Service for other customers.
  3. We take many measures to protect and secure your data. We enforce encryption for data transmission from the public Internet. There are some edge cases where we may send your data through our network unencrypted.
  4. When you use our Services, you entrust us with your data. We take that trust to heart. You agree that Contamos Labs may process your data as described in our and for no other purpose. We as humans can access your data for the following reasons:
    • To help you with support requests you make. We'll ask for express consent before accessing your account.
    • On the rare occasions when an error occurs that stops an automated process partway through. We get automated alerts when such errors occur. When we can fix the issue and restart automated processing without looking at any personal data, we do. In rare cases, we have to look at a minimum amount of personal data to fix the issue. In these rare cases, we aim to fix the root cause to prevent the errors from recurring.
    • To safeguard Contamos Labs. We'll look at logs and metadata as part of our work to ensure the security of your data and the Services as a whole.
    • To the extent required by applicable law. As a US company with all data infrastructure located in the US, we only preserve or share customer data if compelled by a US government authority with a legally binding order or proper request under the Stored Communications Act, or in limited circumstances in the event of an emergency request. If a non-US authority approaches Contamos Labs for assistance, our default stance is to refuse unless the order has been approved by the US government, which compels us to comply through procedures outlined in an established mutual legal assistance treaty or agreement mechanism. If Contamos Labs is audited by a tax authority, we only share the bare minimum billing information needed to complete the audit.
  5. We use third party vendors and hosting partners to provide the necessary software, networking, storage, and related technology required to run the Services. You can see a list of our
  6. Under the California Consumer Privacy Act ("CCPA"), Contamos Labs is a "service provider", not a "business" or "third party", with respect to your use of the Services. That means we process any data you share with us only for the purpose you signed up for and as described in these Terms and the We do not retain, use, disclose, or sell any of that information for any other commercial purposes unless we have your explicit permission. And on the flip-side, you agree to comply with your requirements under the CCPA and not use Contamos Labs' Services in a way that violates the regulations.
  7. If you are a European Union consumer, you will benefit from any mandatory provisions of the law of the country in which you are resident in.

Copyright and Content Ownership

  1. All content posted on the Services must comply with U.S. copyright law.
  2. You give us a limited license to use the content posted by you in order to provide the Services to you, but we claim no ownership rights over those materials. All materials you submit to the Services remain yours.
  3. We do not pre-screen content, but we 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 Company owns all right, title, and interest in and to the Services, including all intellectual property rights therein, and you obtain no ownership rights in the Services as a result of your use. 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 logos or any Service logos for promotional purposes. Please requests to use logos. We reserve the right to rescind any permissions if you violate these Terms.
  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 of the Company.

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.

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.

Third-Party Services

To enable our Services, we integrate with the YouTube Data API. Therefore, when you use our Services, now or in the future, you are agreeing to be bound by YouTube's Since we use the YouTube Data API, you are also agreeing to be bound by the when using our Services.

Third-Party Websites, Applications and Ads

Sometimes, you may find links in our Services that take you to other websites, applications, or advertisements (“Third-Party Websites,” “Third-Party Applications,” and “Third-Party Ads”). If you click one of these links, please know that you are leaving Contamos Labs and will be subject to the terms and policies of that third party. We don’t control these third-party sites, apps, or ads, and we’re not responsible for what happens on them. We provide these links for your convenience, but we don’t review, endorse, or make any promises about them or the products and services they offer. If you decide to interact with any third-party website, application, or ad, you do so at your own risk. Once you leave our Services, our Terms and policies no longer apply. We encourage you to review the terms and privacy policies of any third-party site or service before you engage with them or share any information.

Liability

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

You agree that the Company is not liable to you or to any third party for damages of any kind that result from the use of the Services, in ability to access data, or unauthorized access of your data or account. The Company is also not liable for damages of any kind related to actions of any third party that uses the Services, or any other consequences related to the Terms or Services.

If you have a question about any of these Terms, please
