By using any WellerDeveler website or product ("the Services"), you agree to these Terms of Service. WellerDeveler operates a network of free web tools, premium digital products, and a newsletter. If you do not agree, please do not use the Services.
WellerDeveler provides free online tools (ToolStack, CalcHub, WriterTools, etc.), premium digital products sold via Gumroad, SaaS add-ons, and a free newsletter. All services are provided "as is" without warranties of any kind.
Our browser-based tools are free and require no account. All data processing happens locally in your browser. We make no guarantees about tool accuracy or availability.
Digital products are sold through Gumroad. Refunds follow Gumroad's standard 30-day refund policy. If you are unsatisfied with any purchase, contact support@wellerdeveler.com within 30 days.
Some pages across our network contain affiliate links. When you click on an affiliate link and make a purchase, we may earn a commission at no extra cost to you. This helps support the free tools and content we provide. Affiliate relationships do not influence our editorial content.
All original content, designs, and branding across the WellerDeveler network are our property. Product names and trademarks mentioned on our sites belong to their respective owners. Digital products are licensed, not sold -- you may use them for personal and commercial purposes but may not redistribute the files themselves.
All tools and content are provided for informational and utility purposes only. We do not guarantee accuracy, completeness, or suitability for any particular purpose. You are responsible for verifying any output before relying on it.
To the maximum extent permitted by law, WellerDeveler shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of the Services. For purchased products, our total liability shall not exceed the purchase price paid.
If you subscribe to our newsletter, you can unsubscribe at any time via the link in any email. We will not share your email with third parties for marketing purposes.
We may update these terms from time to time. The "Last updated" date at the top reflects the most recent revision. Continued use of the Services after changes constitutes acceptance.
These terms are governed by the laws of the State of New Jersey, USA.
