Terms of Service: Using the Site
PDGPT provides online calculators that run in your browser, with no sign-up and no account required. You may use the calculators for personal, study, and work purposes, and you may link to PDGPT pages from your own website, provided the link is honest and does not suggest that PDGPT endorses you or your site.
You are responsible for the numbers you enter and for checking results before you rely on them. The Disclaimer explains that results are estimates, not professional advice, and the Privacy Policy explains what information the site does and does not collect.
Terms of Service: Free Service
All calculators on PDGPT are free to use. There are no paid tools, no trials, and no subscriptions, and PDGPT will never ask you to pay to see a result. If any page, message, or advertisement appears to ask for payment in the name of PDGPT, it is not part of PDGPT, and you should not trust it. Please report it through the Contact PDGPT page so we can investigate.
Because the service is free, PDGPT may change, add, or remove tools and pages at any time, without notice, and may pause the site for maintenance. We aim to keep the site fast and available, but we do not guarantee uninterrupted access.
Terms of Service: Acceptable Use
You agree not to use PDGPT in a way that harms the site or other visitors. That includes trying to break into the site, overloading it with automated requests, copying large parts of the site to present as your own, or using the site for unlawful purposes. You also agree not to send abusive, misleading, or unlawful material through the contact form, and not to include personal information that PDGPT does not need, such as passwords or bank details.
If you misuse the site, PDGPT may block your access and may remove or ignore messages sent in breach of these terms.
Terms of Service: Our Content
The text, formulas, worked examples, and design of PDGPT are owned by PDGPT, except for outside reference material, which belongs to its own owners. You may read, print, and share individual calculator results for your own use. You may not copy whole pages, or the site’s design, and present them as your own work. Short quotations with a link back to PDGPT are welcome, provided they are accurate and do not mislead readers.
Outside links on PDGPT pages are provided for background only. PDGPT does not control outside websites and is not responsible for their content, products, or privacy practices.
Terms of Service: Liability
PDGPT is provided on an as-is basis, without warranties of any kind. To the fullest extent permitted by law, PDGPT is not liable for any loss or damage arising from your use of the calculators, from errors in results, or from temporary unavailability of the site. This does not limit any rights that cannot be limited by law. If any part of these terms is found unenforceable, the remaining parts continue to apply.
Terms of Service: Changes and Contact
These Terms of Service may be updated from time to time. The current version is always the one on this page, and continued use of the site after a change means you accept the updated terms. If you have a question about these terms, please use the Contact PDGPT page. You can also read the About PDGPT page for a plain-language description of the site, or return to the PDGPT homepage to use the free calculators.
