Privacy Policy
Last updated: May 2, 2025
1. Introduction
At Sestio ("we," "us," or "our"), we are committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you visit our website and use our portfolio risk calculator and related services (collectively, the "Service").
Our Commitment to Your Privacy: We designed Sestio with privacy in mind. Unlike many finance platforms, our portfolio risk calculations are performed locally in your browser, which means your portfolio data typically does not leave your device or get stored on our servers unless you explicitly choose to save it.
Please read this Privacy Policy carefully. By accessing or using our Service, you acknowledge that you have read, understood, and agree to be bound by all the terms of this Privacy Policy.
2. Information We Collect
Portfolio and Financial Data
Local Processing: When you use our portfolio risk calculator, the portfolio data you enter (such as ticker symbols, allocation percentages, and other portfolio details) is processed locally in your browser. This data is not transmitted to or stored on our servers unless you explicitly save your portfolio by creating an account and using our save feature.
If you choose to save your portfolio data to your account, we store this information securely on our servers to provide you with persistent access to your saved portfolios across devices.
Account Information
If you create an account, we collect:
- Email address
- Name (if provided)
- Authentication information (managed securely through our authentication provider)
Automatically Collected Information
When you use our Service, we may automatically collect certain information about your device and usage patterns. This information may include:

This information helps us improve our Service and user experience but does not include your portfolio or financial data.

4. Data Sharing and Disclosure
We do not sell, trade, or otherwise transfer your personal information to third parties for marketing purposes. We may share information in the following limited circumstances:
Service Providers
We may share information with trusted third-party service providers who assist us in operating our website, conducting our business, or providing services to you. These providers have access to your information only to perform specific tasks on our behalf and are obligated to protect your information. Examples include:

Legal Requirements
We may disclose your information if required to do so by law or in response to valid requests by public authorities (e.g., court order, government request).

If we are involved in a merger, acquisition, or asset sale, your information may be transferred as part of that transaction. We will notify you via email and/or a prominent notice on our website of any change in ownership or uses of your personal information.
Protection of Rights
We may disclose information where we believe disclosure is necessary to protect our rights, enforce our policies, respond to claims that content violates others' rights, or protect anyone's safety or rights.
With Your Consent
We may share your information in any other circumstances where we have your explicit consent.
5. Data Security
We implement appropriate technical and organizational security measures to protect your personal information from unauthorized access, alteration, disclosure, or destruction. Our security measures include:
- Encryption of data in transit using SSL/TLS protocols
- Secure storage of any saved data using industry-standard encryption
- Regular security assessments and penetration testing
- Access controls and authentication mechanisms
- Regular security training for our team members
- Browser-based local calculation to minimize data transmission
While we strive to use commercially acceptable means to protect your personal information, no method of transmission over the Internet or electronic storage is 100% secure. We cannot guarantee absolute security.
Data Retention: We only retain personal information for as long as necessary to fulfill the purposes outlined in this Privacy Policy, unless a longer retention period is required by law. For account information, we retain this data until you request deletion of your account.

8. Third-Party Links
Our Service may contain links to third-party websites, services, or applications that are not owned or controlled by Sestio. This Privacy Policy only applies to our Service, and we have no control over and assume no responsibility for the content, privacy policies, or practices of any third-party services.
We encourage you to review the privacy policies of any third-party services you access via links from our Service.
9. Compliance with Financial Regulations
While Sestio provides portfolio risk analysis tools, we are not a regulated financial institution, broker-dealer, or investment adviser. We do not offer financial advice, execute trades, or manage client funds.
However, we are committed to maintaining high standards of data protection and privacy in accordance with applicable laws and regulations, including those relevant to financial services where applicable.
Our local-first calculation approach for portfolio data reflects our commitment to privacy and security in the financial analysis space.
10. Children's Privacy
Our Service is not directed to individuals under the age of 18. We do not knowingly collect personal information from children. If we become aware that we have collected personal information from a child without verification of parental consent, we will take steps to remove that information from our servers.
11. International Data Transfers
Your information may be transferred to and processed in countries other than the country in which you reside. These countries may have data protection laws that differ from your country.
When we transfer your information to other countries, we will protect that information as described in this Privacy Policy and in accordance with applicable law. We use appropriate safeguards for international transfers, such as Standard Contractual Clauses, to ensure your data is protected.
12. Changes to This Privacy Policy
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date.
For significant changes, we will provide a more prominent notice, which may include sending an email notification to users who have provided us with their email address.
We encourage you to review this Privacy Policy periodically for any changes. Your continued use of the Service after any modifications to the Privacy Policy constitutes your acceptance of those changes.
