Privacy Policy
We’re committed to your privacy. Learn how we handle your data securely.
Your Data Stays in Your Browser
Our calculators and image/PDF tools run entirely in your browser. The numbers you enter, the files you select, and the results you generate are processed locally on your device and are never uploaded to Sailwynd or any server. Nothing you compute or convert leaves your device.
Contact & Newsletter Forms
If you choose to send us a message or sign up for updates, our contact and newsletter forms submit the details you enter (such as your name, email address, and message) to Formspree, a third-party form-handling service, so we can receive and respond to you. This happens only when you deliberately submit a form. Formspree processes this data under its own privacy policy.
Third-Party Content Delivery
To power interactive charts and page behavior, this site loads a few small JavaScript libraries from a third-party content delivery network (CDN). As with any resource loaded from a third-party CDN, your browser's request may expose your IP address and basic technical details (such as your browser type) to that provider. These libraries only render the site and never receive your calculator inputs or files.
Advertising
When advertising is enabled, this site may display ads served by Google AdSense. In that case, Google and its partners may set cookies and use similar technologies to serve and measure ads. Ads and their cookies are only present while advertising is enabled; if ads are turned off, no AdSense cookies are set. You can learn about and control ad personalization through Google's Ads Settings.
Your Choices
You can disable or clear cookies and use your browser's privacy settings at any time. Because the calculators and tools run locally, they work even with cookies disabled. If you have questions about how your data is handled, contact us at hello@sailwynd.com.
