Every product on this page is designed and produced by the FunnyTools team (Btcson Lab) — our own learning materials or software source-code tools, not third-party affiliate offers. Checkout and file delivery happen on Gumroad or Payhip; payment and refund policies follow the platform pages. Please review the product description and age range before buying.
These products are not the same as the affiliate links on the Support page: they are not commission links — they are learning materials and a software toolkit sold directly. After you complete checkout on Gumroad or Payhip, the platform delivers the download directly; FunnyTools receives what remains after that platform's own transaction fees, not a percentage-based referral commission like the Shopee or Coupang links on the Support page.
Refunds, receipts, and payment methods all follow Gumroad's or Payhip's own platform rules — FunnyTools does not process payments or refund requests separately. If you have a question about what a product actually contains after buying it, start with that product's page on the platform where you purchased it, since the description and support policy live there.
Revenue from this store has one direct purpose: covering the domain, hosting, and development time behind the free tools elsewhere on FunnyTools. The free tool pages do not change features or show more ads depending on whether you buy anything here — the store and the free tools are separate revenue paths, and the store's existence has no effect on whether the tools keep working.
Before buying, read the described content scope and the listed age range on each product page. The age ranges on learning kits are a design guideline, not a guarantee that a specific child's level matches; the STEM mission packs require the materials listed on their own product pages to complete the activities, so check what you already have on hand before purchasing.
None of the products on this page use countdown timers, stock-scarcity counters, or other urgency prompts to push a purchase decision; prices are listed plainly, and there is no bundling discount that disappears if you wait. If a product page description does not answer a specific question you have, such as file format, printable page count, or whether an activity needs supervision, treat that as a reason to ask before buying rather than assume the answer is favorable.
