Privacy Policy

Effective date: [October 1, 2026]
Last updated: [October 1, 2026]

This Privacy Policy explains how WorkweekMath.com (“WorkweekMath,” “we,” “us” or “our”) collects, uses and shares information when you use our website, calculators, downloadable templates and embeddable widgets (together, the “Services”). WorkweekMath is operated by Sunteco Joint Stock Company. Our contact details are at the end of this policy.

1. Information you enter into calculators

Our calculators process your inputs (such as clock-in and clock-out times, breaks, hourly rates, dates and state selection) locally in your web browser. We do not receive, store or sell these inputs.

• Shareable links. If you use the “Share” or “Copy link” feature, your inputs are included in the web address (URL). Anyone with that link can see those inputs. Like any URL you visit, it may also be recorded in your browser history and in standard server and analytics logs.
• Exports. PDF, CSV and print files are generated in your browser and saved to your device. We do not receive a copy.
• Your device. Some tools may remember your preferences (such as 12-hour or 24-hour format) in your browser’s local storage. You can clear this at any time in your browser settings.

2. Information we collect

Information you give us. We collect information you choose to send us:

• Your email address, if you request a template by email or sign up for updates.
• Your name, email address and message, if you contact us, report an error or submit a form.

Information collected automatically. When you visit the Services, we and our service providers automatically collect:

• Device and browser information: browser type, operating system, device type, screen size and language.
• Usage information: pages viewed, links clicked, the referring website, date and time of visits, and approximate location (city or region) derived from your IP address.
• Log and security data: your IP address, request details and error logs, used to operate and protect the website.
• Download and link counts: which templates are downloaded and which outbound or affiliate links are clicked, counted in aggregate.
• Information from cookies, pixels and similar technologies (see Section 4).

We do not ask for, and you should not send us, sensitive information such as Social Security numbers, bank details or pay stubs.

3. How we use information

• To provide, maintain and improve the Services, including fixing errors in calculators.
• To send templates or updates you requested, and to respond to your messages.
• To understand how the Services are used, measured in aggregate.
• To show advertising that keeps the Services free (see Section 5).
• To protect the Services against fraud, spam, abuse and security incidents.
• To comply with legal obligations and enforce our terms.

4. Cookies and similar technologies

Cookies are small text files stored on your device. We use:

• Essential cookies, needed for security, performance and remembering your privacy choices.
• Analytics cookies, which help us understand site usage. We use [Google Analytics 4]. Learn more about how Google uses information from sites that use its services.
• Advertising cookies, used by our advertising partners to show, measure and personalize ads (see Section 5).

You can control cookies through our cookie settings link at the bottom of every page, and through your browser settings. Blocking some cookies may affect how the site works.

5. Advertising

We use third-party advertising companies, including [Google AdSense], to serve ads on the Services. These third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visits to our site and other sites on the Internet.

You can opt out of personalized advertising by visiting Google’s Ads Settings. You can also opt out of many third-party vendors’ use of cookies for personalized advertising at aboutads.info and networkadvertising.org. If you opt out, you will still see ads, but they may be less relevant to you.

Affiliate links. Some pages link to products for which we may earn a commission. When you click one of these links, the partner may set its own cookies to track the referral. Their privacy policies govern that tracking.

6. How we share information

We do not sell your name or email address. We share information only with:

• Service providers that act on our behalf, such as website hosting, content delivery and security ([Cloudflare]), analytics ([Google Analytics]) and email delivery ([MailerLite / Brevo]). They may use the information only to provide services to us.
• Advertising partners, as described in Section 5. Under some U.S. state laws, allowing advertising partners to collect data through cookies for targeted advertising may be treated as a “sale” or “sharing” of personal information. See Section 8 to opt out.
• Legal and safety recipients, when required by law or legal process, or when needed to protect the rights, property or safety of our users, the public or us.
• Business transfers, in connection with a merger, acquisition or sale of assets, subject to this policy.

7. Embedded widgets

Other websites may embed our calculators. When you use an embedded WorkweekMath calculator, your inputs are still processed in your browser. Embedded widgets do not display ads. We may receive standard technical and log data (such as your IP address and the address of the embedding page) so we can deliver the widget. The website hosting the embed has its own privacy policy.

8. Your privacy rights and choices

Depending on where you live, including California, Colorado, Connecticut, Virginia, Utah, Texas, Oregon and other states with consumer privacy laws, you may have the right to:

• Know what personal information we collect, use and disclose, and access a copy of it.
• Correct inaccurate personal information.
• Delete personal information we hold about you.
• Opt out of the sale or sharing of personal information and of targeted advertising.
• Not be discriminated against for exercising these rights.
• Appeal our decision on your request, where your state law provides that right.

How to opt out of targeted advertising: Use the “Your Privacy Choices” link in our site footer. We also honor the Global Privacy Control (GPC) signal: if your browser sends GPC, we treat it as a request to opt out of sale, sharing and targeted advertising for that browser.

How to make other requests: Email [privacy@workweekmath.com] with the subject “Privacy Request.” We will verify your request using the information you provide, such as the email address you used with us. You may use an authorized agent where your state law allows. We will respond within the time required by applicable law, normally 45 days.

Email: You can unsubscribe from our emails at any time by using the link in any email we send.

Do Not Track: Browsers’ “Do Not Track” settings have no common industry standard, so we do not respond to them. We do honor Global Privacy Control as described above.

Notice for California residents

In the past 12 months we may have collected these categories of personal information: identifiers (such as email address and IP address); internet or other electronic network activity (such as browsing and interaction data); and geolocation data (approximate location only). The sources, purposes and recipients are described in Sections 2, 3 and 6. We may have disclosed identifiers and internet activity to advertising partners in a way that may be considered a “sale” or “sharing” under California law. You can opt out as described above.

We do not collect sensitive personal information for the purpose of inferring characteristics about you. We keep personal information only as long as described in Section 10. We have no actual knowledge of selling or sharing the personal information of consumers under 16.

9. Children’s privacy

The Services are intended for a general audience and are not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has given us personal information, contact us and we will delete it.

10. Data retention

• Email subscriber data: until you unsubscribe or ask us to delete it.
• Messages and error reports: up to [24 months] after the matter is resolved.
• Server and security logs: up to [90 days], unless needed longer to investigate a security issue.
• Analytics data: according to our analytics settings, currently [14 months].

11. Security

We use reasonable administrative, technical and physical safeguards to protect personal information, including encrypted connections (HTTPS) and access controls. Our operator, Sunteco, maintains an information security management system certified to ISO/IEC 27001. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

12. International data transfers

WorkweekMath is operated from Vietnam, and our service providers may process information in the United States and other countries. By using the Services, you understand that your information may be transferred to and processed in countries whose data protection laws may differ from those where you live. We take steps to protect it as described in this policy.

13. Third-party websites

Our pages link to other websites, including government sources and software providers. We are not responsible for their privacy practices, and we encourage you to read their privacy policies.

14. Changes to this policy

We may update this Privacy Policy from time to time. When we do, we will change the “Last updated” date at the top of this page. If we make material changes, such as starting to store calculator inputs for a new account feature, we will provide a more prominent notice before the change takes effect.
