Privacy Policy
How SonoCalculator approaches information, calculator inputs, cookies, third-party services and your privacy choices.
SonoCalculator is designed to provide practical online calculators with as little unnecessary personal-data collection as reasonably possible. This Privacy Policy explains the types of information that may be processed when you visit the website, why that information may be used, and the choices available to you.
Information you provide directly
If you contact SonoCalculator by email, we may receive the information you choose to include, such as your email address, message, calculator name, example inputs, screenshots or other details. We use that information to respond to inquiries, investigate reported problems, improve calculators and address legitimate website matters.
Please do not send passwords, authentication codes, full financial-account details, government identification numbers, medical records or other information that is not necessary for your inquiry.
Calculator inputs
SonoCalculator calculators generally use the values you enter to generate results in the page itself. Calculator inputs may include numbers such as measurements, rates, prices, dates, income amounts or other values needed for a formula. They are provided for calculation purposes and should not be treated as a secure storage system.
Some calculations concern sensitive topics such as money or health. Use non-identifying values where possible. Calculator results are informational and the privacy of information you later copy, save, email or share outside SonoCalculator depends on the service you use to do so.
Technical and usage information
Like most websites, hosting, security, analytics or delivery infrastructure may process technical information needed to deliver and protect the site. Depending on the services enabled, this can include IP address, browser and device information, requested pages, timestamps, referring pages, approximate location derived from an IP address, diagnostic events and security logs.
This information may be used to operate the website, detect abuse, troubleshoot failures, understand general site usage and improve performance. We do not claim that every category listed here is collected by every visit; actual processing depends on the services operating on the site.
Cookies and similar technologies
Cookies, local storage or similar technologies may be used for functions such as remembering preferences, security, measurement or advertising when those features are enabled. Some technologies are set by SonoCalculator and others may be set by third-party providers.
For a focused explanation, including browser controls and the difference between essential, analytics and advertising technologies, see our Cookie Policy.
Analytics and advertising
SonoCalculator may use analytics or advertising services as the website develops. If advertising such as Google advertising services is enabled, advertising providers may use cookies or similar technologies subject to their own policies and applicable consent requirements. If analytics services are enabled, they may process usage information to help understand traffic and website performance.
We do not describe a particular analytics or advertising product as currently active unless it is actually implemented. This policy should be reviewed whenever the site's service providers or data practices materially change.
Third-party services and external links
The website may rely on hosting, content-delivery, security, analytics, advertising or other service providers. It may also link to websites operated by other organizations. Third parties have their own privacy practices, and SonoCalculator does not control how an external website handles information after you leave our site.
How information may be used
- Provide, maintain and secure SonoCalculator.
- Respond to messages and investigate calculator corrections.
- Diagnose technical problems and improve usability.
- Understand general website performance and usage when measurement tools are enabled.
- Prevent spam, fraud, abuse or attacks.
- Meet legal obligations and protect legitimate rights where applicable.
We do not ask visitors to create an account simply to use ordinary calculators.
Retention and security
Information should be retained only as long as reasonably needed for the purpose for which it was collected, operational or security needs, dispute resolution, or applicable legal obligations. Retention can differ by service provider and data category.
Reasonable technical and organizational measures can reduce risk, but no internet transmission, email system or storage method can be guaranteed completely secure. Visitors should avoid sending unnecessary sensitive information.
Your privacy choices and rights
You can control many cookies through browser settings and, where provided, website consent controls. Blocking some technologies may affect site functionality. Depending on where you live, privacy law may provide rights concerning access, correction, deletion, restriction, objection or other handling of personal information. The availability and scope of those rights depend on applicable law and the circumstances.
For a privacy-related request, contact us with enough information to understand the request. We may need to verify a request where reasonably necessary and legally permitted.
Children's privacy
SonoCalculator is a general-audience calculator website and is not designed to solicit personal information from children. If you believe a child has provided personal information in a way that requires attention, contact us so the situation can be reviewed.
International visitors and policy changes
SonoCalculator can be accessed from different countries. Privacy requirements differ by location, and service providers may process information in countries other than the visitor's own subject to their applicable safeguards and terms.
We may update this Privacy Policy when website features, providers, laws or practices change. Material changes will be reflected by updating the date shown on this page. Visitors should review the current version when privacy practices are important to their use of the site.
