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.
Contacting Us
We don’t run any contact or newsletter forms, so there’s nothing to submit to a third party. If you email us at [email protected], we use your message solely to reply to you — we don’t add you to a mailing list or share it with anyone else.
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
We don’t show ads. No advertising cookies or ad-tracking scripts are loaded on this site.
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 [email protected].
