1. About these terms
These Terms of Service govern your use of Focustack, provided by Focustack LLC ("Focustack," "we," "us," or "our"). Our business mailing address is 5441 S Macadam Ave, Ste N, Portland, OR 97239, and our support contact is support
Focustack is a learning workspace for YouTube videos and playlists. The current beta is free and available to individuals aged 18 or older for personal use, with initial promotion and invitations focused on the United States. It provides learning tools such as notes, timestamp bookmarks, tasks and flashcards, together with Flia, an AI study assistant.
You must accept these Terms and agree to our Privacy Policy through the presented acceptance process before using the application's features. If you do not agree, do not use those features. Agreement to these documents is separate from an optional marketing subscription and does not replace any additional permission required for a particular use of information.
2. Eligibility and accounts
You must be at least 18 years old and legally able to enter into this agreement. The beta is not offered to users under 18 or for school-managed student accounts. You must provide accurate account information, keep your sign-in credentials secure and notify us at support
You may not share your account to bypass eligibility, access restrictions or usage limits. You are responsible for your use of the service and content you submit, subject to applicable law.
3. Free beta and service changes
The current beta has no subscription fee. Access may require an invitation and may be subject to feature, storage or AI usage limits. Features may change, contain errors or be interrupted. We do not promise continuous availability or a particular learning outcome. Keep copies of information that is important to you.
We may change or end the beta and will provide appropriate notice where practical and as required by law. If we introduce paid features, their price and applicable payment terms will be presented separately before you choose to purchase them. Participation in this free beta does not authorize future charges.
4. Your content and our limited permission to use it
As between you and Focustack, you retain the rights you have in the notes, messages and other content you provide. You must have the rights or permissions necessary to provide that content and request the processing you choose. Adding a link does not transfer ownership of the linked material to you or to Focustack.
You grant us non-exclusive permission to host, store, reproduce, transmit, display to you and process your content as reasonably necessary to operate, secure and support the service and provide the features you request, including processing through service providers as described in our Privacy Policy. This permission is limited to those purposes and does not transfer ownership of your content to us.
The permission continues only as needed for those purposes, applicable retention and deletion processes, and legal obligations. It does not grant us a general right to sell your notes or publicly publish your private learning records.
5. Flia and AI-generated material
Flia generates responses using your request and the context included with it. Responses and lesson summaries can be inaccurate, incomplete or inappropriate. Check important information against the original material and reliable sources. Flia does not guarantee that you have mastered a topic, that an answer is correct, or that a task has been completed in the application.
Do not rely on Flia as a substitute for professional medical, legal, financial or other regulated advice. Do not use it to make decisions that require qualified professional judgment without appropriate review. Avoid submitting sensitive information that is unnecessary for your learning activity.
AI-generated material may be similar to material generated for other users. We do not promise that output is unique, copyrightable or free of third-party rights. Any rights you have to use output remain subject to applicable law, these Terms and relevant third-party rights. Provider data handling is described in the Privacy Policy.
6. YouTube and other third-party services
Focustack uses YouTube API Services and embedded YouTube video playback. By using Focustack's YouTube API client features, you agree to be bound by the YouTube Terms of Service. Google's handling of information is described in the Google Privacy Policy.
Videos and other third-party materials remain subject to their owners' rights and the terms of the relevant service. Their availability, accuracy, advertising and continued access are outside our control. We do not grant you a right to download, reproduce or redistribute third-party videos merely because you can view them in Focustack. Use of learning tools and AI does not remove those restrictions.
Focustack is not affiliated with or endorsed by YouTube. Third-party names and marks identify their respective services and owners.
7. Acceptable use
Do not use Focustack to:
- Violate law or another person's intellectual-property, privacy or other rights.
- Upload or request unlawful content, malware, harassment, exploitation or abuse.
- Obtain unauthorized access to accounts, systems or information.
- Circumvent authentication, age restrictions, usage limits or safety controls.
- Scrape, disrupt or overload the service or interfere with other users.
- Misrepresent your identity or use the service to deceive others.
- Use AI features in ways prohibited by applicable provider restrictions incorporated into the permitted operation of the feature.

8. Service rights and feedback
Focustack and its licensors retain their rights in the service's software, design and branding. Subject to these Terms, you may access the service for your permitted personal use during the beta. This does not transfer ownership of the service to you.
If you voluntarily send suggestions about the service, we may use those suggestions to improve it without an obligation to compensate you. This provision does not authorize us to disclose your private learning content or override the Privacy Policy.
9. Suspension, termination and deletion
You may stop using Focustack at any time and request account deletion using the process on our Contact & Privacy Requests page. Logging out or revoking a Google connection does not itself delete your Focustack account.
We may restrict or suspend access when reasonably necessary to address misuse, a security threat, ineligibility, legal requirements or material breach of these Terms. Where appropriate and legally permitted, we will explain the action and provide a way to contact us about an error. We may also end the beta as described above.
Access restrictions do not themselves erase stored information. Retention and deletion are governed by our Privacy Policy and applicable law. Provisions that need to continue after access ends, such as applicable intellectual-property rights and dispute provisions, survive to the extent appropriate and lawful.
