Updated June 19, 2026Your calculator inputs stay on your device
All calculator logic runs entirely in your browser. When you use our tools, your numbers are processed locally on your device. We do not receive, store, or transmit your calculator inputs to any server.
Calculator data
When you move sliders or change inputs on tools like the Freelance Rate Calculator or Hosting Cost Comparison, your numbers are processed locally on your device. We do not receive, store, or transmit your calculator inputs to any server.
Information we may collect
Contact form
If you use our contact form, we collect your name, email address, and message so we can reply to you. Submissions are processed by Web3Forms, which forwards the message to us by email. We do not use contact form data for marketing unless you explicitly ask to be added to our newsletter.
Email newsletter
If you subscribe to our email list, we collect your email address to send you new tool announcements and freelance business tips. You can unsubscribe at any time via the link in any email. We do not sell email addresses to third parties.
Automatically collected data
Like most websites, our hosting provider (Vercel) and any analytics or advertising services we use may collect standard log data such as your IP address, browser type, pages visited, and referring URL. This helps us understand traffic and improve the site.
Affiliate links
Some pages include affiliate links to third-party services (e.g. hosting, invoicing, accounting tools). When you click these links, the third party may collect information according to their own privacy policy. We may earn a commission at no extra cost to you. Affiliate relationships do not influence our calculator results — all tool math is independent and client-side.
Third-party services
We may use the following types of third-party services:
- Vercel — website hosting and delivery
- Web3Forms — contact form delivery to our inbox
- Email provider (e.g. ConvertKit or Resend) — newsletter delivery, when connected
- Analytics — to understand site usage (when enabled)
- Google AdSense — display advertising (only after approval and when enabled)
Each third party has its own privacy policy governing how they handle your data.
Children's privacy
DevBizTools is not directed at children under 13. We do not knowingly collect personal information from children.
Your rights
Depending on your location, you may have rights to access, correct, or delete personal data we hold about you (such as your email address if you subscribed). Contact us to make a request.
Changes to this policy
We may update this policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Continued use of the site after changes constitutes acceptance of the revised policy.
