Terms of Use

Last updated 2026-10-11

All services provided on this website are owned and operated by SKYSEED TECH LLC.

By using watertreatmentsource.com you agree to these terms. If you do not agree, please do not use the site.

What you make with the tools: free for commercial use

Everything you generate with the tools on this site (puzzles, worksheets, coloring pages, charts, cards, printouts and downloads, “your output”) is yours to use for any purpose, including commercial use, royalty-free and worldwide. You may print it, share it, use it in class, and include it in products you sell, such as books on Amazon KDP, printables on Etsy, Teachers Pay Teachers, Gumroad or Shopify, and print-on-demand items. No attribution or credit is required.

Two limits: material by third parties that is listed on the credits page (for example text under CC BY-SA) keeps its own licence, including any credit it asks for; and you may not copy, resell, mirror or repackage the site itself, its code, its generators or its design as a competing tool or service, or use automated tools to copy the site in bulk or to overload it.

No warranty

We test the tools against independently calculated results, but mistakes can happen; check anything important before you rely on it. The site is provided “as is”, without warranties of any kind. To the fullest extent the law allows, we are not liable for any loss arising from use of the site. Nothing here limits liability that cannot be limited by law.

Content and licences

The site’s design, text and code are © WaterTreatmentSource. Third-party material is listed with its licence on the credits page, and that licence applies to it.

Advertising and third-party services

The site may show advertising and may use visit statistics. These are described in the privacy policy. We are not responsible for the content of other websites we link to.

Changes and contact

We may update the site and these terms at any time; the date below the title shows the latest change. Questions: jun@watertreatmentsource.com. Nothing in these terms limits the consumer rights you have under the law of your own country.
