Privacy Policy

Bison Brush LLC Privacy Policy

This Privacy Policy explains how Bison Brush LLC ("Bison Brush," "we," "us," or "our") handles information when you use StoryChat AI, Math Sheet Prints, this website, or otherwise contact us through bisonbrush.com.

1. What This Policy Covers

This Policy applies to:

• StoryChat AI
• Math Sheet Prints
• The Bison Brush website
• Support and business communications sent to [email protected]

2. How StoryChat AI Handles Data

StoryChat AI is built to keep normal summarization workflows on your Apple device. That means:

• Your conversation text and generated summaries are intended to stay on-device during supported local summarization flows.
• Bison Brush does not need your private chat content on our own servers in order for the app's standard on-device summary features to work.
• If you choose to export, share, or copy content from the app, that action is controlled by you.
• If you install a local model in the app, the model files may be downloaded from a third-party model host or repository provider. That provider may receive standard download-request information such as IP address, request headers, and download timing.

3. Information We May Receive

Information you provide directly

• Support emails, feedback, bug reports, and any attachments you send us
• Business inquiries or launch-update requests
• Information you intentionally share with us when asking for help

Information related to app distribution and purchases

• If one of our apps is distributed through the Apple App Store, Apple may provide us limited transaction or product-status information needed to understand purchases, refunds, or support issues.
• We do not receive your full payment card number from Apple.

Technical information from website or download infrastructure

• Basic technical logs such as IP address, browser or device type, and request timing may be processed by our hosting, CDN, email, or model-download providers for security, delivery, and abuse prevention.

4. What We Do Not Use for This Product Setup

• No Firebase or RevenueCat services are used in the current product setup described on this website.
• We do not sell personal information.
• We do not run advertising trackers inside the current local-first StoryChat AI setup described here.

5. Why We Use Information

We may use information we receive to:

• Respond to support requests and product questions
• Help users with App Store purchases or app-access issues
• Maintain website availability and security
• Investigate bugs, misuse, or abuse reports
• Improve product quality and clarify product documentation

6. When Information May Be Shared

We may share limited information only when reasonably necessary:

• With Apple for App Store distribution, app review, TestFlight, purchases, refunds, or platform operations
• With infrastructure providers that host our website, email, or model downloads
• When required by law, legal process, or to protect users, Bison Brush, or the public
• As part of a business transfer such as a merger, acquisition, or sale of assets

We do not sell or rent your personal information.

7. Retention

• Support emails and attachments may be kept for as long as reasonably needed to handle the issue, maintain business records, or resolve follow-up requests.
• Technical logs may be kept for operational, security, or fraud-prevention purposes for a limited period determined by the relevant provider or business need.
• Content stored only on your device remains under your control unless you choose to share or export it.

8. Your Choices

• You can choose whether to email us or request launch updates.
• You can choose whether to install local models, share summaries, or export content from StoryChat AI.
• You can contact us to request deletion of support communications you previously sent, subject to any legal or recordkeeping obligations.

9. Children's Privacy

Our products and website are not intended to knowingly collect personal information from children under 13 without appropriate consent. If you believe a child has provided personal information to us inappropriately, please contact us and we will review the request.

10. International Users

Bison Brush LLC is based in the United States. If you contact us from another country, your information may be processed in the United States or by service providers operating in other jurisdictions.

11. Changes to This Policy

We may update this Privacy Policy from time to time as our apps, distribution setup, or website changes. When we do, we will update the "Last updated" date on this page.
