Privacy Policy

Last updated: August 19, 2026

Information processed when you visit the site

Like most websites, our hosting, security and delivery systems may automatically process technical information when a page is requested. This can include an IP address, browser and device information, referring page, requested URL, date and time, general location derived from network information, and diagnostic or security data.

This information may be used to operate the site, prevent abuse, troubleshoot errors, understand traffic patterns and maintain security.

Calculator inputs

Most Series Calculator tools are designed so the values you type into calculator fields are processed in your browser by the calculator interface. We do not intentionally require you to create an account or submit ordinary calculator inputs to our server in order to receive a result.

This does not mean that a browser session is completely anonymous. Normal server logs, cookies, advertising technologies or analytics services can still process website-usage information as described elsewhere in this policy. If a future calculator collects or transmits additional information, that functionality should be disclosed on the relevant page.

Cookies and similar technologies

Cookies are small pieces of data stored on or read from a browser or device. Series Calculator and third-party services may use cookies, local storage, pixels, web beacons, IP addresses or similar technologies for security, preferences, measurement and advertising.

You can control or delete cookies through your browser settings. Blocking some cookies may affect website features or the way advertising is delivered.

Google AdSense and third-party advertising

Series Calculator may use Google AdSense and other third-party advertising services to display ads. Third-party advertising vendors, including Google, may use cookies or similar technologies to serve, measure and personalize advertising based on visits to this website and/or other websites, subject to applicable law and user consent choices.

Google and its advertising partners may process information such as cookie identifiers, IP addresses, browser/device information, ad interactions and page visits for purposes that can include ad delivery, frequency control, fraud prevention, measurement and personalization.

You can manage Google’s advertising personalization choices through Google Ads Settings. You may also learn about choices offered by participating advertising companies through YourAdChoices.

Analytics and measurement

We may use analytics or measurement services to understand how people discover and use the website, which pages are useful, and where technical or usability improvements are needed. If Google Analytics or another analytics provider is enabled, that provider may process information according to its own terms and privacy practices.

Analytics configuration can change as the site develops. We aim to use measurement data for website operation, content improvement and performance analysis rather than to collect unnecessary personal information.

Information you choose to provide

If you voluntarily contact us, report an error, send feedback or otherwise communicate with Series Calculator, we may receive the information you choose to provide, such as your name, email address and message. We use that information to respond, investigate the issue, maintain records and improve the website.

Please do not send sensitive personal, medical, financial-account, identity or confidential business information through ordinary website communications unless it is specifically required and an appropriate secure method is provided.

How information may be used

• Operate, secure and maintain Series Calculator.
• Deliver calculator pages and website features.
• Detect spam, fraud, abuse, automated attacks and technical problems.
• Measure traffic, performance and general usage trends.
• Improve calculator interfaces, content, navigation and site performance.
• Serve and measure advertising where advertising is enabled.
• Comply with legal obligations and enforce applicable policies.
• Respond to messages, corrections or other voluntary communications.

How information may be shared

Information may be processed by service providers that help operate the website, such as hosting, content-delivery, security, analytics and advertising providers. We may also disclose information when required by law, legal process, regulation, security needs, or to protect rights and prevent abuse.

If the website or its assets are transferred as part of a merger, acquisition, financing, reorganization or sale, relevant information may be transferred subject to applicable law.

Third-party websites

Our pages may link to official sources and other external websites. Their privacy practices are controlled by those third parties, not Series Calculator. Review the privacy notice of any external website you visit.

Data retention

Retention periods depend on the type of information and why it is processed. Security logs may be retained for operational purposes; analytics and advertising providers may use their own retention settings; correspondence may be kept as reasonably necessary to respond to a request or maintain records.

We aim not to keep personal information longer than reasonably necessary for the purpose for which it was collected, subject to legal, security and operational requirements.

Your privacy choices and rights

Depending on where you live, applicable privacy law may give you rights concerning certain personal information, which can include rights to access, correct, delete, restrict or object to processing, or to opt out of certain targeted advertising or data uses. These rights vary by jurisdiction and may be subject to exceptions.

You can also use browser controls to manage cookies and the advertising-choice links provided above. Where a consent-management message is displayed, use its controls to update the choices made through that system.

Children’s privacy

Series Calculator is a general-audience informational website and is not directed to children under 13. We do not knowingly ask children under 13 to provide personal information through ordinary calculator use. If you believe a child has provided personal information in a way that should be removed, contact the site operator through the contact method made available on the website.

Security

We use reasonable technical and operational measures intended to protect the website and information processed through it. No website, internet transmission or storage system can be guaranteed completely secure, so users should avoid sending sensitive information through ordinary website channels.

Contact us about privacy

If you have a privacy question or want to make a request concerning information you have provided through the website, contact us at instantwebtool@gmail.com. Please do not include unnecessary sensitive information in an ordinary email.

Changes to this Privacy Policy

We may update this Privacy Policy when website features, advertising services, legal requirements or our data practices change. The “Last updated” date at the top of the page identifies the current version. Material changes should be reflected in the published policy before or when the related practice changes.

About advertising and editorial independence

Advertising helps support Series Calculator, but advertising relationships do not change calculator formulas, outputs or editorial review standards. See our About page and Disclaimer for more information.
