Privacy Policy

1 Overview

At Time Addition Calculator ("we," "our," or "us"), accessible via https://www.timeaddition-calculator.com, we take your privacy seriously. This Privacy Policy outlines what information we collect, how it is handled, and your rights when using our online time calculators, tools, and informational guides.

Our tools are designed to work without requiring account registration, personal profiles, or logins.

2 Client-Side Calculation Privacy (Zero Calculation Data Collection)

All math operations across our platform—including the Time Addition Calculator, Time Subtraction Calculator, Hours Worked Calculator, and Timesheet Calculator—run entirely within your web browser using client-side JavaScript.

• The numbers, hours, minutes, seconds, and timestamps you input are processed locally in your device's memory.
• We do not record, store, or transmit your calculation entries, timesheet numbers, or notes to our servers.
• Once you close or refresh your browser tab, your active calculation session data clears automatically.

3 Log Files and Server Telemetry

Like most websites, our hosting servers automatically record basic, non-personally identifiable technical details when you access our pages. This log data may include:

• Internet Protocol (IP) addresses
• Browser type and version
• Operating system type
• Referring and exit pages
• Date and time stamps of requests

This information is used strictly to diagnose technical issues, analyze general site performance, prevent malicious bot attacks, and ensure reliable server uptime. It is not linked to any personal identity.

4 Cookies and Local Storage

We use cookies and HTML5 Local Storage for essential website functions:

• Consent Status: We store a small preference flag (tac_cookie_consent) in your browser's local storage so you do not see the cookie consent banner repeatedly on return visits.
• Display Preferences: Local storage may be used to save your preferred calculator display format (such as HH:MM vs. HH:MM:SS).

For a comprehensive list of all storage items and guidance on how to manage or disable them in your browser, please review our dedicated Cookies Policy.

5 Advertising Partners & Google AdSense Disclosures

To keep our calculation tools 100% free for everyone, we may display third-party advertisements through networks such as Google AdSense. In accordance with Google AdSense policies and privacy standards:

• Third-party vendors, including Google, use cookies to serve ads based on your prior visits to our website or other websites across the Internet.
• Google's use of advertising cookies enables it and its partners to serve personalized or non-personalized ads based on your visits to our site and other destinations online.
• You may opt out of personalized advertising at any time by visiting Google Ads Settings.
• Alternatively, you can opt out of third-party vendor cookies for personalized advertising by visiting AboutAds.info.

6 Contact Form and Direct Communications

When you submit inquiries, feedback, or formula reports via our Contact Form or by emailing support@timeaddition-calculator.com, we receive your name, email address, and message content.

We use this communication information solely to answer your questions, resolve technical issues, and provide customer support. We never sell, rent, or share your contact details with external marketers.

7 Your Rights Under GDPR and CCPA

Depending on your location, you may have specific statutory rights under data protection laws such as the European Union's General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA):

• Right of Access & Deletion: You have the right to request information regarding any personal data we hold about you and request its deletion. Because we do not require accounts or store calculation data, our stored data is generally limited to voluntary support emails.
• No Sale of Personal Data: We do not sell, rent, or trade your personal information.
• Non-Discrimination: We do not discriminate against any user who exercises their privacy rights.

8 Children's Privacy

Our website provides utility math and calculation tools intended for general audiences. We do not knowingly collect personal identifiable information from children under the age of 13. If you believe a child has provided us with personal information, please contact us so we can promptly delete it.
