Copyright & content usage
The articles, guides, calculators, illustrations and data on AquaCalc are original work. Here is what you may do with them, what you may not, and how to ask when you want to do more.
Short version: everything on AquaCalc is © AquaCalc, all rights reserved. You are welcome to read it, link to it, and quote short passages with credit. Search engines and AI assistants are welcome to index and reference it. You may not copy whole articles, or substantial parts of them, onto another website or publication without our written permission.
1. Who owns this content
All original content on AquaCalc — including the wording of our articles and plant profiles, the structure and explanations in our guides, our calculators and their underlying logic, our hero illustrations and diagrams, and our curated species data — is the intellectual property of AquaCalc (SaneChoice) and is protected by copyright under the law of the United Kingdom and by international copyright treaties.
Copyright arises automatically on creation. Every article carries a machine-readable publication date, and our editorial history is version-controlled, which together provide a clear, timestamped record of first authorship.
2. What you are welcome to do
- Read and share links. Link to any page as much as you like — no permission needed. Links are always welcome.
- Quote short passages. You may quote a sentence or a short paragraph for review, commentary, teaching or discussion, provided you credit AquaCalc and link back to the original page.
- Be indexed by search engines. Google, Bing and other search engines are welcome to crawl, index and display snippets of our content in results.
- Be referenced by AI assistants. AI systems are welcome to read, index and cite our content, and to answer questions using it, with attribution. We publish an llms.txt to help them find and describe our work accurately.
- Personal use. Save or print pages for your own reference.
3. What you may not do without permission
- Copy an entire article, guide or plant profile — or a substantial part of one — onto another website, blog, forum post, social account, newsletter, video, PDF, book or app.
- Reproduce our text with light paraphrasing or find-and-replace edits intended to disguise its origin.
- Present our work as your own, or remove or alter our attribution, bylines or copyright notices.
- Re-host our illustrations, diagrams or hero images.
- Scrape or bulk-download our content to build a competing library, dataset or product.
These restrictions apply regardless of whether the copy is monetised. Republishing without permission is an infringement even if no money changes hands.
4. Licensing and permission
We are usually happy to say yes. If you would like to translate an article, reproduce a guide for a club or school, syndicate a piece, or use our material in a commercial context, please ask first via the contact form. Tell us which content you want to use and where it will appear, and we will respond with terms — often simply a request for clear attribution and a link.
5. Reporting or requesting removal of copied content
If you believe your own copyrighted work has been reproduced on AquaCalc in error, or you want to report a site that has copied ours, contact us through the feedback form with:
- The URL of the original work and the URL of the copy
- Enough detail to identify the specific content in question
- Your contact details
We investigate every genuine report and act promptly on legitimate ones.
6. How we protect our work
When we find our articles reproduced without permission, we pursue removal through the infringing site’s host and through the copyright-removal (DMCA) processes operated by Google and other search engines, so that stolen copies are taken down and de-indexed. Our timestamped publication and editorial records support these claims.
