Privacy Policy

This page explains what information OptionalSoftware collects through optionalsoftware.com, how that information is used, and how website data differs from the data processed by our self-hosted products.

Last updated: March 23, 2026

Website analytics

We use analytics on our marketing and product pages to understand what content is useful and how the site is performing.

Contact submissions

If you contact us through the website, we process the information you provide so we can respond and protect the site from abuse.

Self-hosted products

Our products are designed to run on your infrastructure. We generally do not receive the content they process unless you deliberately send it to us.

1. Scope

This Privacy Policy applies to optionalsoftware.com and the website pages, forms, and related marketing content published there by OptionalSoftware, a division of Castle Enterprises. It does not govern how you or your organization collect, store, or process data inside your own deployment of an OptionalSoftware product.

2. Information we collect

Information you provide directly

  • Your name, email address, subject line, and message when you use the contact form.
  • Any additional information you choose to include in your message or correspondence with us.

Usage, device, and diagnostic information

  • Pages viewed, navigation events, referring pages, and similar site usage activity.
  • Technical information such as browser type, device characteristics, timestamps, and standard network or request metadata.
  • Server-side diagnostics and abuse-prevention information, including rate-limiting, CSRF, and anti-spam related events.

3. How we use information

We use the information collected through the website to:

  • Operate, secure, and maintain the site.
  • Respond to sales, partnership, support, and general inquiries.
  • Detect spam, abuse, fraud, and other misuse of the site or contact form.
  • Understand which pages and products are useful so we can improve our website and messaging.
  • Comply with legal obligations and protect our rights, users, and systems.

4. Analytics, cookies, and third-party services

Our marketing and product pages use PostHog analytics to measure page views and site interactions. Depending on the page and your browser settings, analytics tools may use cookies or local storage to recognize sessions and understand repeat visits.

We also load certain third-party resources, such as Google Fonts, which may receive limited technical information like your IP address, browser information, and request details as part of delivering those resources.

You can control cookies and similar technologies through your browser settings. Blocking them may affect how some analytics or convenience features behave.

5. How we share information

We may share limited information with:

  • Service providers that help us operate the site, analytics, hosting, or communications.
  • Castle Enterprises personnel or contractors supporting OptionalSoftware operations.
  • Authorities or counterparties when required by law or when reasonably necessary to protect rights, safety, systems, or users.

We do not sell personal information collected through this website.

6. Self-hosted product data

OptionalSoftware products are built to be lightweight and self-hosted. In normal use, the data those products ingest, store, or process remains on your infrastructure, not ours. If you choose to send us logs, screenshots, exports, or other materials for support, sales, or troubleshooting, we may process that information for those purposes.

7. Retention and security

We retain website information for as long as reasonably necessary for the purposes described above, including security, operations, recordkeeping, and responding to inquiries. We use reasonable administrative and technical measures to protect information we control, but no system can be guaranteed perfectly secure.

8. Your choices and requests

If you would like to ask about information you submitted through this site, request an update, or ask us to delete information you sent through the contact form, please contact us through the website. We will review reasonable requests in light of our legal, operational, and security obligations.

9. Changes to this policy

We may update this Privacy Policy from time to time. When we do, we will post the updated version on this page and revise the “Last updated” date above.
