1. Who We Are

MultiYAxis ("we," "us," or "our") is the developer and publisher of the MultiYAxis Excel Add-in, available through the Microsoft AppSource marketplace, and the operator of the website located at multiyaxis.com.

2. Information We Collect

• Account and Purchase Information: When you purchase a licence, our payment processor (Polar) collects your name, email address, and payment information. We receive only your email address and order details — we never store credit card data.
• Support Communications: If you contact our support team, we retain your email address and the contents of your message in order to respond to and resolve your inquiry.
• Usage Data: The Add-in may transmit anonymous, non-identifiable telemetry data (e.g., feature usage counts, error reports) solely for the purpose of improving the product. This data cannot be used to identify you personally.
• Website Analytics: Our website may use privacy-friendly analytics to measure aggregate traffic. No personally identifiable information is collected in this process.

3. How We Use Your Information

We use the information we collect to:

• Deliver and activate your licence.
• Respond to support requests and provide customer service.
• Send transactional emails (receipts, licence confirmations).
• Improve the functionality and performance of the Add-in.
• Comply with applicable legal obligations.

We do not sell, rent, or share your personal information with third parties for marketing purposes.

4. Data Processed Inside Microsoft Excel

The MultiYAxis Add-in processes spreadsheet data (cell values, ranges, chart configurations) locally within your Microsoft Excel session. This data is used exclusively to render charts within your workbook and is never transmitted to our servers or stored outside your local environment.

5. Third-Party Services

We use the following third-party services, each governed by their own privacy policies:

• Microsoft AppSource / Microsoft 365: Your use of the Add-in is subject to Microsoft's Privacy Statement.
• Polar: Handles payment processing. See Polar's Privacy Policy.

6. Data Retention

We retain purchase and support records for as long as necessary to fulfill the purposes described above or as required by law. You may request deletion of your personal data at any time by contacting us.

7. Your Rights

Depending on your location, you may have rights under applicable data protection laws, including the right to access, correct, or delete personal data we hold about you. If you are located in the European Economic Area or United Kingdom, you have rights under the GDPR, including the right to lodge a complaint with your local supervisory authority.

8. Cookies

The multiyaxis.com website is a static informational site and does not use tracking cookies or persistent identifiers for advertising purposes. Session cookies may be used for basic website functionality.

9. Children's Privacy

The MultiYAxis Add-in and website are not directed at children under the age of 13. We do not knowingly collect personal data from children.

10. Security

We implement reasonable technical and organizational measures to protect your personal information against unauthorized access, loss, or disclosure. However, no method of transmission over the internet is completely secure.

11. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date at the top of this page. Continued use of the Add-in or website after changes are posted constitutes your acceptance of the updated policy.
