Last updated: August 24, 2026

Donut Calculator is developed and operated by Hanna Yurkevich (“we”, “us”, or “our”).

These Terms of Use (“Terms”) govern your use of Donut Calculator. By downloading, accessing, or using Donut Calculator, you agree to these Terms.

1. Donut Calculator

Donut Calculator is a calculator application that provides calculation features and related functionality.

We may update, modify, add, or remove features from the app over time.

2. License to Use Donut Calculator

Subject to these Terms and the applicable app-store terms, we grant you a limited, personal, non-exclusive, non-transferable, and revocable license to use Donut Calculator for your personal lawful use.

You may not:

• copy, distribute, sell, sublicense, or commercially exploit the app except where permitted by law;
• interfere with the normal operation or security of the app; or
• use Donut Calculator for unlawful purposes.

Nothing in these Terms transfers ownership of Donut Calculator, its design, software, branding, or other intellectual property to you.

3. Calculator Results

Donut Calculator is provided as a general-purpose calculator.

Although we aim to provide accurate calculations and reliable functionality, we do not guarantee that every result will be error-free or suitable for every purpose.

You are responsible for verifying results where accuracy is important, particularly before relying on them for financial, legal, medical, engineering, business, or other consequential decisions.

4. Availability and Changes

We may update or change Donut Calculator from time to time, including its features, design, and compatibility.

We may also discontinue the app or particular features where reasonably necessary.

Updates may be required to continue using some functionality.

5. Privacy

Your use of Donut Calculator is also subject to the Privacy Policy, which explains how information is collected and handled.

6. Third-Party Services

Donut Calculator may rely on services provided by third parties, including Apple, Google, and analytics providers.

The availability and operation of some features may therefore depend on services that we do not control.

Your use of third-party services may also be governed by their own terms and privacy policies.

7. Disclaimer

To the extent permitted by applicable law, Donut Calculator is provided on an “as is” and “as available” basis without warranties of any kind beyond those that cannot legally be excluded.

Nothing in these Terms excludes any warranty, guarantee, consumer right, or other protection that cannot be excluded or limited under applicable law.

8. Limitation of Liability

To the extent permitted by applicable law, we are not liable for indirect, incidental, special, or consequential losses arising from your use of, or inability to use, Donut Calculator.

Nothing in these Terms limits or excludes liability where doing so would be prohibited by applicable law.

9. Changes to These Terms

We may update these Terms if Donut Calculator, applicable laws, or related services change.

When these Terms are updated, the “Last updated” date at the top of this page will be changed.

If a change materially affects your rights, we will provide any additional notice required by applicable law.
