Terms of Use

Who you are dealing with

The Calcufetti website and its calculators are operated by Konstantīns Pobilojs. Contact: privacy@calcufetti.com.

The paid Calcufetti Extension is published and licensed by MedWeb Solutions, Inc., and Paddle acts as its authorised reseller and Merchant of Record. That means your purchase contract for Calcufetti Pro is with Paddle: Paddle is the seller shown on your receipt, collects the payment and any applicable sales tax, and handles order and billing support.

The service

Calcufetti provides calculators, converters and explanatory content. The website and the free Calcufetti Extension are provided without a usage fee and without requiring an account. Features may be added, changed or discontinued as the project develops.

Calcufetti Pro is a paid extension tier. A Calcufetti account is required to purchase and hold Pro access, so that paid access reuses your existing identity rather than a separate licence key. Pricing is published on the pricing page and refunds are described in the Refund Policy.

Informational results

Results are provided for general informational purposes. They do not replace financial, legal, medical, tax or other professional advice. You remain responsible for checking inputs, assumptions and any result used for an important decision.

Accounts

You are responsible for providing accurate account information, protecting your credentials and notifying Calcufetti of suspected unauthorised access. You may delete saved calculations and close your account through the available account controls.

Acceptable use

Do not misuse the service, attempt unauthorised access, interfere with availability, automate abusive request volumes, submit unlawful content or use Calcufetti to infringe another person's rights.

Intellectual property

The Calcufetti name, site design, original text and software are protected by applicable intellectual-property law. You may use calculation results for your own purposes, but may not copy or republish substantial parts of the service without permission or another applicable legal basis.

Availability and liability

Calcufetti is maintained with reasonable care, but uninterrupted availability and error-free results cannot be guaranteed. Nothing in these terms excludes liability that cannot lawfully be excluded, including mandatory consumer rights.

Applicable law

Applicable law and mandatory consumer protections remain effective regardless of these terms. Nothing here limits rights that cannot lawfully be waived or excluded.

Changes and contact

Material changes will be published on this page with an updated date. Questions may be sent to privacy@calcufetti.com.
