Pricing
Free and Pro
The free extension is the real product. Pro pays for repeated-work convenience, never for correct answers.
Calcufetti Pro is not on sale yet. The prices below are the planned launch prices and are published so you can decide before you install anything.
Free
US$0. No account, no card, no trial clock.
Everything needed to get a correct answer on the page you are reading:
- select any number or measurement and convert or calculate it;
- manual Unit Lens on a page, after you ask for it;
- Quick Math and Copy;
- a session scratch tape;
- sensible display precision and compound units where supported;
- no registration required at any point.
Correctness, parser quality and safety fixes stay in Free permanently. You will never have to pay to avoid a known wrong answer.
Pro
One paid tier, two ways to pay for it. Both give you exactly the same Pro.
US$39 per year — billed yearly, cancel whenever you like.
US$79 once — Founding Lifetime. Same Pro, paid a single time, for early buyers.
Pro removes the repetition when you use the same pages every day:
- Unit Lens applies itself automatically on sites you explicitly choose;
- saved per-site Lens settings;
- preferred output units;
- precision and rounding profiles.
A free Calcufetti account is required to buy and hold Pro, so your access follows your account instead of a licence key you have to keep somewhere.
Automatic behaviour uses per-site browser permission that you grant and can revoke. Calcufetti never asks for access to every website, and never records what you convert.
Billing
Prices are in US dollars. Local taxes may be added at checkout depending on where you are.
Payments are processed by Paddle acting as Merchant of Record. Paddle is the seller shown on your receipt and handles the payment transaction and applicable sales taxes.
Calcufetti Extension is published and licensed by MedWeb Solutions, Inc., and Paddle resells it to you as Merchant of Record.
Refunds are available for 30 days, no reason needed. See the Refund Policy.
The annual plan can be cancelled at any time and keeps working until the end of the period you paid for. Founding Lifetime is a one-time purchase with nothing to cancel.
