Privacy Policy | Calctrick - Free Online Calculator Tools

Introduction

CalcTrick ("CalcTrick," "we," "our," or "us") provides online calculators, converters, educational resources, and related website features (collectively, the "Services"). This Privacy Policy explains how we collect, use, disclose, retain, and protect information when you visit or use our Services.

By using CalcTrick, you acknowledge that you have read this Privacy Policy. If you do not agree with this Privacy Policy, please do not use the Services.

This Privacy Policy should be read together with our Cookie Policy and Terms of Service.

Information We Collect

We collect information in the following categories.

Personal Information You Provide

You may choose to provide personal information when you:

Create or manage an account
Contact us for support, feedback, or business inquiries
Subscribe to newsletters or product updates
Save calculator results, preferences, or tool settings
Participate in surveys, promotions, or other interactive features
Purchase paid features, credits, subscriptions, or other services if offered

This information may include:

Name or display name
Email address
Account login details and authentication information
Communications you send to us
Billing-related information, such as transaction identifiers and purchase history

We do not intentionally collect full payment card numbers. Payment card details are processed by our payment providers, and we receive limited transaction information needed to confirm payments, provide receipts, prevent fraud, and support accounting or compliance obligations.

Calculator and Tool Inputs

When you use a calculator or tool, you may enter values such as numbers, measurements, dates, financial assumptions, health-related estimates, or other inputs. These inputs are used to generate the requested calculation result.

Unless a specific feature clearly states that results can be saved, shared, or associated with your account, calculator inputs are generally processed to provide the tool output and are not intended to identify you directly. However, technical logs, analytics tools, browser storage, or saved-result features may capture limited contextual information about your use of a tool.

You should avoid entering highly sensitive personal information unless it is necessary for the calculation and you are comfortable doing so.

Cookies and Tracking Technologies

Cookies are small files stored on your browser or device. Similar technologies, such as pixels, tags, local storage, and device identifiers, can perform related functions. We use the following categories.

Essential cookies are required for the website to work correctly. They may be used to:

Maintain secure sessions and login status
Remember consent choices and privacy settings
Protect forms and accounts from abuse
Balance traffic across servers
Support security, fraud prevention, and debugging
Deliver calculators and core website functionality

Because these cookies are necessary, they cannot usually be disabled through our site controls. You can block them in your browser, but parts of the Services may not function properly.

Analytics Cookies

Analytics cookies help us understand how people use CalcTrick. For example, we may use Google Analytics or similar analytics tools to measure page views, sessions, approximate geography, browser and device information, traffic sources, and interactions with calculators or content.

Analytics data is generally used in aggregated or pseudonymous form to improve the Services. Where required, analytics cookies are used only after consent.

Deliver ads and sponsored content
Measure ad performance
Prevent repeated or irrelevant ad delivery
Detect invalid traffic and ad fraud
Support contextual, interest-based, or personalized advertising where permitted

Advertising partners may combine information collected on CalcTrick with information from other websites or services according to their own privacy policies.

Language or region
Calculator defaults and display preferences
Theme, layout, or accessibility settings
Recently used tools or saved non-sensitive preferences

Third-Party Services

We use third-party service providers to operate, measure, secure, monetize, and improve CalcTrick. These providers process information according to their own terms and privacy policies and, where applicable, our instructions.

Google Analytics

We may use Google Analytics to understand website traffic and usage patterns. Google Analytics may collect information such as page views, session data, approximate location, browser and device information, and interactions with the Services. Google provides controls such as browser settings, consent tools, and opt-out mechanisms that may limit analytics collection.

We may work with Google AdSense, Google advertising services, and other advertising networks to display ads, measure ad performance, detect invalid traffic, and support advertising operations. These partners may use cookies, pixels, and similar technologies to collect information about your visits to CalcTrick and other websites.

Cloud Hosting and Infrastructure

We use cloud hosting, database, content delivery, security, logging, and monitoring providers to deliver the Services reliably. These providers may process IP addresses, server logs, device information, and other technical data needed to host, secure, troubleshoot, and improve the Services.

Communications, Email, and Support Tools

We may use email delivery, customer support, notification, and survey providers to send messages, manage inquiries, and collect feedback.

Payment Providers

If paid services are available, we may use payment processors to handle payment details securely. We do not store full credit card numbers on our servers.

Legal or Safety Disclosures

We may disclose information if we believe it is reasonably necessary to comply with law, respond to lawful requests, protect security, prevent fraud or abuse, enforce our policies, or protect the rights and safety of CalcTrick, our users, or others.

Data Retention

We retain information only for as long as reasonably necessary for the purposes described in this Privacy Policy, unless a longer retention period is required or permitted by law.

Retention periods vary depending on the type of information:

Account information is kept while your account is active and for a reasonable period after closure to support security, dispute resolution, backups, and legal obligations.
Support communications are retained as needed to respond to requests, improve service, and maintain records.
Transaction and billing records are retained as required for accounting, tax, fraud prevention, and legal compliance.
Analytics data is retained according to the settings of the relevant analytics tools and is usually aggregated or pseudonymized where practical.
Security logs are kept for a limited period unless they are needed to investigate abuse, fraud, or security incidents.
Backup copies may persist for a limited time until they are overwritten or deleted according to our backup practices.

When information is no longer needed, we delete it, anonymize it, aggregate it, or otherwise handle it according to applicable law.

Children's Privacy

CalcTrick is a general-audience website and is not directed to children under 13. We do not knowingly collect personal information from children under 13. Children under 13 may not create accounts, submit personal information, or use features that require personal information.

Secure hosting and infrastructure controls
Access controls and authentication safeguards
Monitoring, logging, and abuse prevention systems
Limited access to personal information based on business need

No website, internet transmission, or storage system is completely secure. We cannot guarantee absolute security, but we work to protect information against unauthorized access, disclosure, alteration, and destruction.

International Data Transfers

CalcTrick and our service providers may process information in countries other than the country where you live. These countries may have privacy laws that are different from those in your jurisdiction.

When we transfer personal information internationally, we rely on appropriate legal mechanisms and safeguards where required, such as contractual protections, adequacy decisions, user consent, or other lawful transfer mechanisms.
