Privacy policy

CalcLogicPro provides calculators without requiring an account. This policy explains what information may be processed when you use the site and how advertising and consent technologies operate.

Calculator inputs

Calculator values are sent to the server to produce the result shown on the page. Calculating alone does not save a plan in an application database. Because calculator forms use shareable web addresses, submitted values may appear in the page URL. Those URLs can be retained in browser history, server logs, bookmarks, messages, or other places where you choose to share them.

Do not enter names, contact details, account information, or other personal or confidential information into calculator fields. You can remove calculator values from a link by deleting everything after the question mark in its URL.

Saved plans and optional Google sign-in

When you choose “This device,” plan names, calculator inputs, links, and result summaries are stored in this browser's local storage. They are not uploaded as saved plans unless you explicitly choose cloud saving or “Copy to cloud.” Device plans remain until you delete them in My plans or clear this site's browser data. Other people using the same browser profile may see them.

Where Google sign-in is available, signing in creates an application account linked to Google's account identifier. The application stores that identifier and your chosen cloud plans. It does not store your Google password, email address, profile photo, or Google access tokens. Google processes the sign-in under its own privacy policy. Essential cookies protect sign-in, your session, and form submissions; the sign-in session lasts up to 14 days and can renew while you use it.

Cloud plans are available only through your signed-in account. You can delete individual plans or delete your account and all its cloud plans in My plans. Account deletion removes these records from the active application database and invalidates the account's sessions on subsequent requests. Device copies remain separate. Backup copies, if maintained by the hosting provider, follow the configured backup retention schedule. My plans does not load advertising scripts.

Information collected automatically

When you request a page, CalcLogicPro and its hosting provider may process standard technical information needed to deliver, secure, and maintain the site. This can include an IP address, date and time, requested URL, referring page, browser and device information, and diagnostic or security events. This information may be retained in operational logs according to the hosting provider's settings and legitimate security needs.

Correction and feedback reports

If you use the contact and corrections form, the calculator address, inputs, observed result, and expected result you submit are recorded in restricted operational logs so the report can be investigated. The form does not request a name or email address. Do not include personal or confidential information in a report.

Google AdSense and advertising cookies

CalcLogicPro uses Google AdSense to display and measure advertising. Third-party vendors, including Google, may use cookies, local storage, pixels, or similar technologies to serve and measure ads. Google and its advertising partners may use advertising cookies to show ads based on your prior visits to CalcLogicPro or other websites. Depending on your location, consent choices, and advertising settings, ads may instead be non-personalized or contextual.

Advertising-related information can include your IP address, browser or device identifiers, pages viewed, ad impressions and interactions, approximate location derived from an IP address, and information associated with cookies. Learn more about how Google uses information from sites that use its services and how Google uses cookies in advertising.

You can manage personalized advertising through Google Ads Settings. You may also be able to opt out of participating third-party interest-based advertising through YourAdChoices. These choices do not necessarily prevent all advertising; they can change whether ads are personalized.

Consent and privacy choices

Where required, CalcLogicPro uses a Google-certified consent management platform to present regional privacy choices. The message may allow you to consent, decline consent, or manage individual purposes and advertising partners. Your choice may be stored so the site can respect it on later visits. Available controls and the advertising behavior that follows can vary by region and applicable law.

You can also use your browser controls to block or delete cookies and other site data. Blocking storage may affect advertising or consent preferences, but the core calculators do not require an account.

Service providers and data retention

CalcLogicPro relies on service providers, including its hosting provider and Google, to operate and monetize the site. Those providers process information under their own terms and privacy policies. Cloud plans remain in the application database until you delete them or your account. Technical logs, backups, consent records, and advertising data may be retained by the relevant provider according to its settings, policies, and operational requirements.

Children's privacy

CalcLogicPro is a general-audience service and is not directed to children under 13. The site does not knowingly request personal information from children through its calculators.

Changes to this policy

This policy may be updated when the site's features, providers, or legal obligations change. The latest version will remain available at this address with its revision date below.
