4.1 Essential Cookies

These cookies are necessary for the website to function properly. They enable core functionality such as remembering your cookie consent preferences.

4.2 Analytics Cookies

We use Google Analytics to understand how visitors interact with our website. Google Analytics uses cookies to collect information such as how often users visit, what pages they view, and what other sites they visited prior to coming to our website. We use this information solely to improve our website and tools.

You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.

4.3 Advertising Cookies

If we display advertisements in the future, our advertising partners may use cookies to display personalized advertisements based on your browsing history and interests. We will update this policy before enabling any advertising on our website.

• Adjust your browser settings to block or delete cookies
• Use browser extensions or privacy tools to control tracking

Please note that disabling certain cookies may affect the functionality of our website. Rejecting cookies does not eliminate advertisements but will result in non-personalized advertising.

5. Advertising

We may display advertisements on our website in the future through third-party advertising networks. These advertisements would help us keep our tools free for users. We will update this policy with specific details before enabling any advertising on our website.

7. Do Not Sell or Share My Personal Information (CCPA/CPRA)

Under the California Consumer Privacy Act (CCPA) as amended by the California Privacy Rights Act (CPRA), California residents have the right to opt out of the "sale" or "sharing" of their personal information.

We do not sell or share your personal information for cross-context behavioral advertising.

To opt out of this sharing, you can:

• Click the cookie settings icon on our website and decline advertising cookies
• Use an opt-out preference signal such as Global Privacy Control (GPC) in your browser

We will not discriminate against you for exercising any of your privacy rights.

8. Do Not Track Signals

Our website honors Global Privacy Control (GPC) signals. When a GPC signal is detected, we treat it as a valid opt-out request for the sale or sharing of personal information. We do not currently respond to legacy Do Not Track (DNT) browser signals, as there is no industry-standard technology for honoring them.

9. Your Rights

Depending on your location, you may have certain rights regarding your personal information under applicable data protection laws, including the GDPR, CCPA/CPRA, and other state and international privacy laws.

9.1 Your Data Protection Rights

To exercise any of these rights, please contact us at [email protected]. We will respond to your request within 30 days.

If you are located in the European Economic Area (EEA), you also have the right to lodge a complaint with your local data protection supervisory authority.

10. International Data Transfers

Your information may be transferred to and processed in countries outside your country of residence, including the United States, where our hosting provider is based. These countries may have data protection laws that differ from those of your jurisdiction.

Where such transfers occur, we rely on appropriate safeguards as required by applicable law, including the EU-U.S. Data Privacy Framework, Standard Contractual Clauses, or your consent where applicable.

11. Data Retention

We retain automatically collected data (such as server logs) for up to 26 months.

Cookie data is retained for the duration specified in the cookie consent settings. Essential cookies persist for the duration of your session or up to one year. Advertising cookies may persist for up to two years, subject to your consent.

12. Data Security

We take reasonable measures to protect the information collected through our website. Our website uses HTTPS encryption to secure data transmitted between your browser and our servers.

However, please be aware that no method of transmission over the Internet or electronic storage is 100% secure. While we strive to protect your information, we cannot guarantee its absolute security.

Since our tools run entirely in your browser and we do not collect sensitive personal data, the risk of data exposure is minimal. In the event of a data breach that may affect your rights, we will notify the relevant authorities and affected individuals as required by applicable law.

13. Children's Privacy

Our website is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us at [email protected].

If we discover that we have collected personal information from a child under 13 without parental consent, we will take steps to delete that information promptly.

This policy complies with the Children's Online Privacy Protection Act (COPPA).

14. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or other factors. When we make changes, we will update the "Last Updated" date at the top of this policy.

We encourage you to review this Privacy Policy periodically to stay informed about how we are protecting your information.
