Privacy Policy

Calculator is a browser-based currency converter and calculator. This policy explains what happens to your data when you use it.

What we store

• Your last-used currencies, custom exchange rate, theme preference, and calculation sheet are saved in your browser's local storage.
• This information stays on your device and is not sent to Calqo's servers or any third party.

What we don't collect

• We don't require an account, email address, or payment details to use the free tools on this page.
• We don't track the amounts or sums you enter.

Future premium features

If you choose to upgrade to a premium plan when it becomes available, a separate checkout process will collect only what's needed to process payment and deliver the plan. We'll update this policy before that launches.

Changes

If this policy changes, the "last updated" date above will change too. Continued use of Calqo after an update means you accept the revised policy.

Terms & Conditions

By using Calculator, you agree to the following terms.

Use of the tools

• The currency converter and calculator are provided free of charge, "as is," for personal and informal use.
• Exchange rates shown are indicative and may be edited manually — they are not live market data and should not be relied on for trading, invoicing, or legal/financial decisions without independent verification.

No warranty

Calculator is offered without warranties of any kind. We do our best to keep calculations accurate, but we're not liable for losses arising from reliance on results shown here.

Premium plan

A paid premium tier is planned for the future, with additional features layered on top of the free tools. The core converter and calculator described above will remain free. Separate terms will apply to any paid plan at launch.

Acceptable use

You agree not to misuse the site — including attempting to disrupt it, scrape it at scale, or use it for unlawful purposes.

Changes to these terms

We may update these terms as the product evolves. The "last updated" date reflects the most recent revision.
