Privacy Policy

1. Who we are and what this policy covers

This Privacy Policy explains how Focustack LLC, operating as Focustack ("Focustack," "we," "us," or "our"), collects, uses, and discloses information when you use our website and learning workspace or communicate with us. Our business mailing address is 5441 S Macadam Ave, Ste N, Portland, OR 97239. You can contact us at privacy@focustack.io.

The initial beta is a free service for individuals aged 18 or older, with initial promotion and invitations focused on the United States. This policy covers our handling of information. Third-party websites and services, including Google and YouTube, also have their own privacy policies.

2. Information we collect

We receive information directly from you, from the providers you use to sign in, and through your interactions with the service.

Categories of information collected
Category	Examples and source
Account and profile	Email address, authentication identifiers, display name, profile image, time zone and preferences. If you use Google Sign-In, Google provides authorized basic profile and account information. Password authentication is handled through our authentication provider. We do not need your Google password.
Learning workspace	YouTube links and playlists you add; video metadata; viewing progress; notes and drafts; timestamp bookmarks; tasks; flashcards, answers and review results; learning activity and focus sessions.
Flia interactions	Your messages, the context included with requests, AI responses, conversation summaries and generated lesson summaries. Context can include selected learning records, video information, a video link or selected time range, and relevant learning summaries.
Communications	Information you provide when requesting access, contacting support, making privacy requests or subscribing to updates.
Technical and usage information	Information needed to operate and secure the service, such as request and error information, browser/device information and IP addresses where processed by our hosting or service providers. Our limited analytics measures visits and selected feature-use events as described below.

Some drafts and preferences are stored in your browser. Content you enter in notes, messages or support requests may contain personal information. Please do not submit passwords, payment-card details or sensitive information that is unnecessary for your learning activity.

3. How we use information

We use information to provide and secure accounts; admit users to the beta; maintain your learning workspace; remember preferences and progress; provide Flia responses and requested lesson preparation; troubleshoot problems; measure limited usage; answer support and privacy requests; and comply with applicable legal obligations.

If you separately subscribe to updates, we use your email address to send those updates. Creating an account or requesting beta access does not automatically subscribe you to our newsletter. We may send necessary account, security and service messages independently of a marketing subscription.

4. Flia and AI processing

When you use Flia, your request and the context included with it are sent to Google's Gemini API to generate a response. Depending on the feature you use, this may include selected notes, tasks, bookmarks or flashcards; relevant conversation history and summaries; learning summaries; or a YouTube URL with a selected time range. Preparing a playlist can involve processing the videos in that playlist and storing generated lesson summaries.

We store conversations and generated summaries to support the learning features you use. Information you put into messages or selected records can be included in the context sent to the provider. AI responses may be inaccurate.

[AI DATA HANDLING DISCLOSURE]

Google Sign-In is used for authentication and basic profile information. This sign-in requests basic identity information rather than access to manage your YouTube account.

Focustack uses YouTube API Services to obtain information about videos and playlists. Videos are displayed through YouTube's embedded player. Loading or interacting with that player allows Google/YouTube to receive information from your device and apply its own technologies and policies; third-party video content may include advertising. AI video processing described above is a separate interaction with Google's Gemini service.

See the Google Privacy Policy and YouTube Terms of Service. You can review third-party connections in your Google Account permissions. Removing a connection does not by itself delete information already stored in Focustack; contact us to request deletion of that information.

6. Service providers and other disclosures

We use Amazon Web Services for application infrastructure, authentication, data and file storage, operational monitoring and authentication email. Google provides Google Sign-In, YouTube services and Gemini AI processing. Our other selected providers are:

Website/application hosting: [HOSTING PROVIDER DISCLOSURE].
Limited product and website analytics: [ANALYTICS PROVIDER DISCLOSURE].
Newsletter delivery and subscription management: [NEWSLETTER PROVIDER DISCLOSURE].

Information is provided to these services for the purposes described in this policy. Their contractual roles and independent processing may differ; in particular, embedded YouTube content and Google account services have their own policies.

We may also disclose information when reasonably necessary to comply with applicable law or valid legal process, protect people and the service, investigate misuse, or exercise or defend legal rights. If the business is transferred or reorganized, information may be transferred subject to applicable law and appropriate notice.

[SALE AND SHARING DISCLOSURE]

7. Cookies, browser storage and analytics

We use cookies and similar technologies for authentication, security, interface preferences and browser drafts. YouTube may use its own technologies when embedded content is loaded. Limited analytics measures visits and selected feature-use events; it is not intended to collect the contents of your notes, chats or flashcards, or the identifiers and titles of videos you study. We do not enable advertising pixels or session recordings as part of this beta's analytics design.

The Cookies & Similar Technologies notice describes the actual technologies and available controls. [ANALYTICS CHOICES DISCLOSURE] [DO NOT TRACK DISCLOSURE] [GLOBAL PRIVACY CONTROL DISCLOSURE]

8. Retention and deletion

We retain information for the purposes described in this policy and for applicable legal, security and operational needs. Retention periods differ by category. [RETENTION SCHEDULE DISCLOSURE]

You may request account deletion through privacy@focustack.io. We verify requests appropriately before acting. Deletion from active systems, retained backups, service providers and browser storage can follow different processes and schedules. [DELETION PROCESS AND TIMING DISCLOSURE]

Revoking beta access, logging out, clearing browser storage and deleting an individual conversation are different actions from deleting your account. Clearing browser storage can remove locally saved drafts and preferences; it does not delete server-side information.

9. Your choices and privacy requests

You can change available profile settings in the application and manage supported learning records through their controls. You can request access to, a copy of, correction of or deletion of your personal information by contacting privacy@focustack.io. We may request information reasonably necessary to verify your identity and authority; please do not send passwords or identity documents with your initial request.

Additional rights and required response procedures depend on applicable law. [APPLICABLE RIGHTS AND APPEALS DISCLOSURE] Where applicable law requires nondiscrimination for exercising privacy rights, we will comply with that requirement.

To stop marketing email, use the unsubscribe link in a newsletter or contact support@focustack.io. This does not stop necessary account and security messages. Further request instructions appear on our Contact & Privacy Requests page.

10. Security and processing locations

We use safeguards designed to protect information, including access restrictions and protections for transmission and storage appropriate to the service. No service or transmission method can be guaranteed completely secure.

[PROCESSING LOCATIONS DISCLOSURE]

11. Age eligibility

The beta is intended for adults aged 18 or older and is not offered to people under 18. If you believe an ineligible person has provided personal information, contact privacy@focustack.io so we can investigate and take appropriate action. Do not submit additional information about a child unless we request what is necessary to address the report.

12. Changes and contact

We will update the effective date when this policy changes and provide additional notice or obtain agreement where required by applicable law or our service commitments. Historical versions will be identified by their version and effective date.
