Notchwillow: Scientific Calculator — Terms of Use
The extension
Notchwillow is a browser extension with a scientific calculator, a programmer mode and a unit converter. This version is free to use. It works offline and keeps your data in your browser, as described in the Privacy Policy.
Your data
Your tape, memory, variables and settings belong to you and stay in your browser profile. You can save a backup at any time and delete everything in Settings. Removing the extension removes its data from the browser.
Accuracy
- Notchwillow keeps exact fractions and whole numbers where it can. Irrational results such as square roots, logarithms and trigonometric values are shown rounded to 14 significant digits.
- Unit conversions use the internationally defined factors; months and years are Gregorian averages. Currencies are not included.
- Check results that matter (for example in finance, engineering, medicine or law) with a second method. Notchwillow is a calculating aid, not professional advice.
No warranty
Notchwillow is provided "as is", without warranties of any kind. Zydeno is not liable for indirect or consequential damages arising from its use, to the extent allowed by law.
Changes
Zydeno may update the extension and these terms. The current version is published at https://zydeno.com/calculator/addons/terms.html.
