This Privacy Policy explains what information is and is not collected when you use Free Histogram Maker (the “Site”), and how any data is handled.
The histogram tool runs entirely in your browser. The numbers you paste or upload are processed on your own device and are never sent to us or stored on a server. Recent charts are saved only in your browser’s local storage and can be cleared at any time.
We do not ask you to create an account and we do not collect your name or email unless you choose to contact us. We use privacy-respecting analytics to understand which pages are popular and how the Site performs. This may include aggregated, non-identifying data such as page views, approximate region, device type and referring site.
The Site uses a small number of cookies and similar technologies. These fall into two groups:
You can clear cookies and local storage at any time in your browser settings, and you can decline non-essential cookies using the notice shown on the Site.
The Site may display advertising provided by third parties, including Google AdSense. 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 the Site and/or other sites on the internet.
You may opt out of personalised advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors’ use of cookies for personalised advertising at aboutads.info. For visitors in the EEA and UK, ad partners obtain consent for personalised advertising where required.
We use Google Analytics to measure Site usage. Google Analytics may set cookies and process usage data on our behalf. You can learn more in Google’s Privacy Policy.
Depending on where you live, you may have rights under laws such as the GDPR or CCPA, including the right to access, correct or delete personal data, and to opt out of certain processing. Because we do not hold accounts or store your chart data, most requests relate to cookies and analytics, which you can control through your browser and the opt-out links above. To make a request, email privacy@freehistogrammaker.com.
The Site is intended for a general audience and is not directed to children under 13. We do not knowingly collect personal information from children.
We may update this policy from time to time. Material changes will be reflected by the “last updated” date above.
