Monetize the deliverable.
Not the result.
Core calculations, method explanations, ordinary exports and access to your local data remain free.
Results remain independent
Sponsorship does not change formulas, inputs, ordering of calculated results or model conclusions. We do not sell calculator inputs or health/financial profiles. No advertising network, session replay, tag manager or hosted product analytics script is included in this release.
The current paid product
The Construction Planning Pack adds an offline estimating workspace, branded deliverables and reusable project files. Checkout is disabled until the seller configures a real Stripe Payment Link and approves the terms and product. Widget licensing and commercial placements are not currently offered.
Static site; external payments
AskCalculators has no application server, webhook receiver, user accounts, hosted project database or entitlement service. An enabled payment button is a plain outbound Stripe Payment Link with no calculator inputs, customer-prefill data or project information appended. No payment API key or Stripe SDK is shipped in the website.
Manual, verified delivery
The seller checks successful payment in Stripe and manually sends the paid ZIP. Paid files are kept outside the public site. A success URL, local-storage flag or return-page visit is not proof of payment and never unlocks a public file. This is not instant automatic delivery or strong DRM.
Clear purchase terms
The product purchase terms identify the seller, contents, price, permitted use, compatibility, delivery timeframe, support and refunds before checkout. Payment records and support communications are separate from the user's calculation projects.
