Synthesize360, LLC ("we", "us", "our") operates Market Fusion IQ, a trading dashboard available as a web application at marketfusion.io and as iOS and Android mobile applications (collectively, the "Service"). This Privacy Policy describes how we collect, use, retain, and disclose information about you when you use the Service.
If you have questions about this policy, please contact us:
Synthesize360, LLC 7901 4th St N, #23545 St. Petersburg, FL 33702 legal@synthesize360.com
This policy applies to both the web application and the iOS and Android mobile applications. Where the policy describes practices that differ between platforms, those differences are called out specifically.
We do not collect, store, or have access to your payment card information. Subscriptions are processed by:
We retain only the following subscription metadata:
Stripe, and Apple or Google if you purchased through them, retain payment records under their own privacy policies. We do not have access to card numbers, billing addresses (beyond what Apple or Stripe surfaces in transaction metadata), or other sensitive payment details.
When you use the AI analyst features of the Service, we currently transmit the following to DigitalOcean, our AI service provider for the analysts:
We do not transmit your email address, display name, password, IP address, watchlist contents, portfolio holdings, cost basis, profit and loss, or any other personally identifying information to this provider.
The prompts sent to this provider are constructed from system templates within the Service. You do not type freeform prompts that are sent to this provider.
This provider's handling of the data is governed by its privacy policy (see Section 4.1).
Questions you type into the Help assistant are currently processed on servers we administer ourselves and are not sent to an outside AI provider.
If you do not use the AI analyst features, no information about you is sent to this provider.
Messages you send to support@marketfusion.io or security@marketfusion.io may be read by an AI assistant provided by Anthropic that helps our staff prepare a reply. Email addresses, phone numbers, long identifiers, links to other websites, and your name are masked before the assistant sees the message. The assistant never replies to you; any reply comes from our staff.
We use the information we collect to:
We do not engage in automated decision-making that produces legal or similarly significant effects on you. The Service's analyses and signals are informational and do not, by themselves, take any action on your accounts.
We share information only with the following categories of recipients.

|---|---|---|
| Apple, Inc. | iOS subscription billing, where offered | Standard purchase metadata Apple requires to process subscriptions |

| Google, LLC (Google Play Billing) | Android subscription billing, where offered | Standard purchase metadata Google requires to process subscriptions |
These providers act on our behalf and are bound by their own privacy policies and contractual obligations. Their privacy policies are available at:
We may disclose information if required by law, court order, subpoena, or governmental request, or where we believe in good faith that disclosure is necessary to protect rights, safety, or property.
If we are involved in a merger, acquisition, financing, or sale of assets, your information may be transferred as part of that transaction. We will notify you by email and by prominent notice in the Service before your information becomes subject to a different privacy policy.
We do not sell your personal information for money or any other valuable consideration. We do not share your personal information with third parties for cross-context behavioral advertising. We do not work with advertising networks, ad-tech companies, or data brokers.

When you delete your account, all data marked "Life of your account" is deleted immediately. See Section 7.
Apple and Stripe retain payment records under their own retention policies. To request deletion of records held by Apple or Stripe directly, contact those companies.
You may request a copy of the personal information we hold about you. To make a request, email legal@synthesize360.com from the address associated with your account. We will verify your identity by confirming your control of that email address and respond within 30 days.
You can correct most account information directly within the Service. For information you cannot edit yourself, email legal@synthesize360.com.
You may request deletion of your account at any time. See Section 7.
You can opt out of promotional emails by clicking the unsubscribe link in any promotional message or by adjusting notification preferences within the Service. Transactional communications such as alerts you have subscribed to and account-security notices are part of the Service and cannot be unsubscribed without modifying or ending the relevant feature.
The Service lets you control which alert types you receive and which delivery channels (email, push notifications, in-app notifications) we use to deliver them.
To delete your account, email legal@synthesize360.com from the address associated with your account, with the subject line "Delete My Account." We will verify your identity and process the deletion within 30 days, confirming completion by email.

If you are a California resident, you have the following rights under the California Consumer Privacy Act and California Privacy Rights Act.
Within the last twelve months we have collected the following categories of personal information about California consumers:
We collect account credentials (email address combined with password). We use this information solely to authenticate you and secure your account. We do not use, disclose, or process this information for any purpose other than providing and securing the Service. Under CCPA, you have the right to limit our use of sensitive personal information; given that we already limit such use to authentication and security, no additional action is necessary, but you may contact us if you have questions.
We collect personal information directly from you, automatically as you use the Service, and from our service providers (Apple and Stripe) when subscriptions are processed.
As described in Section 3.
We do not sell personal information for money or other valuable consideration. We do not share personal information with third parties for cross-context behavioral advertising.
Email legal@synthesize360.com. We will verify your identity by confirming you control the email address associated with your account, then respond within 30 days. You may designate an authorized agent to act on your behalf; we may require written proof of authorization.
The Service is not directed to children under 13. We do not knowingly collect personal information from children under 13. If we become aware that we have collected personal information from a child under 13, we will delete that information promptly. If you believe a child under 13 has provided us with personal information, please contact us at legal@synthesize360.com.
The web application uses two cookies: a strictly-necessary session cookie that keeps you signed in, configured to be sent only over HTTPS, to be inaccessible to JavaScript, and to follow a same-site (Lax) policy; and a theme-preference cookie that remembers your light or dark display setting. We do not use any tracking, analytics, or advertising cookies. Two pages load a provider's script: the checkout pages load Stripe's payment script, which may set Stripe's own cookies to prevent fraud, and the signup page runs Cloudflare's bot check. Each is governed by that provider's privacy policy (see Section 4.1).
The web application also uses browser storage (localStorage and sessionStorage) for display preferences only: your theme setting, the table columns you choose to show on each device, and whether you dismissed a one-time notice on small screens. This storage is not used to track or identify you.
The mobile applications store an authentication token in iOS Keychain (iOS) or Android Keystore (Android). We do not use Apple's IDFA (Identifier for Advertisers), do not show an App Tracking Transparency prompt, and do not track you across other companies' apps or websites.
We do not show a cookie consent banner because we do not use tracking, analytics, or advertising cookies or similar tracking technologies. The cookies and storage described above only keep you signed in, remember display choices, and, on the checkout and signup pages, protect against fraud and automated abuse.
We implement reasonable technical and organizational measures to protect your information, including:
No internet service can be guaranteed completely secure. We will notify you of a security incident affecting your information in the manner and timeframe required by applicable law.
The Service is operated from the United States and is intended only for users located in the United States. Data is processed and stored on infrastructure located in the United States. We do not target the Service to, and do not knowingly accept users from, jurisdictions outside the United States. If you are located outside the United States, please do not use the Service.
We may update this Privacy Policy from time to time. If we make material changes, we will notify you by email and by prominent notice within the Service before the changes take effect. The "Last Updated" date at the top of this policy reflects when the policy was most recently revised. Your continued use of the Service after the effective date of any update constitutes acceptance of the updated policy.
