Privacy Policy

Last reviewed on 2026-04-24.

This Privacy Policy describes how makepiechart.com ("the site", "we", "us") handles information when you visit the site, use the pie chart maker, read a guide, or embed a chart. It applies to every page served from the makepiechart.com domain.

1. Data we collect

1.1 Data you enter into the maker

The labels, values, chart title, colors and style options you type into the pie chart maker are processed entirely within your browser to render the live preview. They are stored in your browser's localStorage so the page survives a refresh. When you use the "Share" feature, chart data is encoded into the URL you copy — it is not transmitted to our servers. We do not receive, log, or store the contents of your charts.

1.2 Server and request logs

Like almost every website, our hosting provider receives standard HTTP request information when you load a page: IP address, user agent, referrer, requested URL, timestamp, and response status. These logs are used to operate and secure the site (debug errors, investigate abuse, analyse traffic patterns) and are retained for a limited period.

1.3 Analytics

We use Google Analytics 4 to understand how visitors find and use the site in aggregate. Google Analytics sets cookies (for example _ga, _ga_*) and collects information such as pages viewed, session duration, device type, approximate location (usually country / region), and referrer. We use this data to prioritise content work, not to identify individual users.

1.4 Advertising

Pages on this site may show advertisements served by Google AdSense and, through AdSense, other third-party vendors. These partners may set and read cookies on your device to measure ad performance, cap the frequency with which ads are shown, and, if you have not opted out, personalise the ads you see. See section 4 for details.

1.5 Information you send us directly

If you email us at the address listed on the contact page, we receive the email content you chose to send and the sending address. We use that information only to respond to you.

2. How we use the information

• To operate and maintain the site and the chart maker.
• To analyse aggregate traffic and improve content and features.
• To serve and measure advertising through Google AdSense and its partners.
• To detect, investigate and prevent abuse (for example, scraping, automated attacks).
• To reply to questions and handle privacy, copyright or abuse requests.

We do not sell personal information. We do not combine the chart data you type with analytics or advertising identifiers — the chart contents never leave your browser.

3. Cookies

We and our partners use cookies and similar technologies (localStorage, pixel tags) for the following purposes:

• Strictly necessary / preferences — remembering your dark-mode setting and your most recent chart in localStorage.
• Analytics — Google Analytics cookies for aggregate traffic measurement.
• Advertising — Google AdSense and partner cookies for ad delivery, frequency capping, measurement and (for eligible users) personalisation.

A more detailed breakdown is available in our Cookie Policy, including how to control and remove cookies in your browser.

4. Google AdSense and third-party vendors

Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.

You can opt out of personalised advertising by visiting Google Ad Settings. You can also opt out of a third-party vendor's use of cookies for personalised advertising by visiting aboutads.info or, in the EU / UK, youronlinechoices.com. Further information about how Google uses data is available in Google's "How Google uses information from sites or apps that use our services" page and Google's advertising policies.

Other vendors participating in the Google advertising ecosystem may also appear. A current list is maintained by Google and accessible through the links above.

5. Legal basis for processing (EEA / UK)

If you are located in the European Economic Area, the United Kingdom or another region with similar rules, we rely on the following legal bases:

• Legitimate interest — for basic server logs, security, and aggregate analytics.
• Consent — for advertising cookies and any personalised advertising, where required. Where a consent banner is shown, your choice controls whether these cookies are set.
• Contract / request — to reply to emails you send us.

6. Your rights

Depending on where you live, you may have the right to:

• Access the personal data we hold about you.
• Request correction or deletion of that data.
• Object to, or restrict, certain processing.
• Withdraw consent for advertising cookies at any time.
• Lodge a complaint with your local data protection authority.

California residents have additional rights under the CCPA / CPRA, including the right to know what categories of personal information are collected and to opt out of the "sale" or "sharing" of personal information as those terms are defined under California law. To exercise any of these rights, email us using the details on the contact page. We will respond within the timelines required by applicable law.

7. Data retention

Server logs are typically retained for a short period (commonly 30–90 days) before being rotated or deleted. Google Analytics data retention is configured per Google's controls and defaults. Emails you send us are kept for as long as needed to handle your request and any reasonable follow-up. Chart data you type into the maker is retained only in your own browser's storage; you can remove it at any time by clearing the page's data in your browser.

8. Children

The site is a general-audience tool and is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has sent us personal information, please contact us and we will delete it.

9. International transfers

Our hosting, analytics and advertising providers may process data in countries other than your own, including the United States. Where required, transfers outside your region are carried out under standard contractual clauses or equivalent safeguards maintained by those providers.

10. Changes to this policy

We may update this Privacy Policy as the site evolves, the law changes, or our partners' practices change. The "Last reviewed" date at the top of this page always reflects the most recent substantive update. Significant changes will be highlighted on the home page or in a visible notice for a reasonable period.

11. Contact

Privacy enquiries can be sent to the email address on our contact page. For disputes that cannot be resolved directly, you may also contact your local data protection authority.

The governing law and supervising authority for this policy is determined by [Jurisdiction] as stated in our Terms of Use.
