THOUGHTFUL FOUNDATIONS

A toolkit built
around the result.

Everyday and scientific

Percentages, discounts, tax, tips, loans and savings; scientific calculations, geometry, statistics and unit conversions.

Calculate offline

Calculations do not require an internet connection. Exchange rates refresh only when you request them; their source dates are shown alongside the result.

You stay in control

No account, advertising or in-app analytics trackers. Keep or clear history on your device, and share a selected result only when you choose to.

SUPPORT

Let’s make it clear.

Contact OSLLC with questions, formula issues, translation corrections or privacy requests.

Include only what is needed: app version, device and steps to reproduce the issue. Please leave out financial, identity and other sensitive information.

Can I use it without internet?

Yes. Calculations and previously downloaded exchange rates work offline. Refreshing rates requires a connection. Rates are daily reference values, not live bank quotes available for trading.

How do I clear my history?

Use the clear option in the app’s History section. You can also remove all local app data through your device’s application settings. OSLLC does not keep your calculation history on a server.

How should I interpret a result?

Check the displayed assumptions, units, dates and rounding. Results are not financial, tax or other professional advice. Provider rates and institutional fees can change the actual outcome.

Which languages are supported?

The interface offers 24 languages, with 247 regional number and date formats. Human review of early-release translations is ongoing; 247 regions does not mean 247 separate languages.
