This policy explains what information Line Slope Finder (lineslope.com) collects, how it is used, and the choices you have. If you have any questions, email contact@lineslope.com.
The Slope Finder keeps your data on your device
The Slope Finder runs entirely in your web browser. The points and numbers you enter, and any photo of a graph you add, are processed on your own device. They are not uploaded to our server, and we do not store them. A photo is removed from memory when you close or reload the page.
Advertising
Line Slope Finder uses Google AdSense to show ads, which keeps the site free.
- 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 this site and/or other sites on the internet.
- You can opt out of personalised advertising by visiting Google’s Ads Settings. You can also opt out of some third-party vendors’ use of cookies for personalised advertising at www.aboutads.info.
Google explains how it uses information from sites that use its services at policies.google.com/technologies/partner-sites.
If you visit from the UK, the European Economic Area or Switzerland, you will be asked for consent before personalised ads or advertising cookies are used. You can change your choice at any time through the privacy and cookie settings link on the page.
Information collected automatically
Like most websites, our web server records basic technical information when you visit: your IP address, browser type, the pages you request and the time of each request. We use these logs only to keep the site secure and working properly, and we keep them for a limited time.
Cookies
- Advertising cookies set by Google and its partners, as described above.
- Consent cookies that remember your advertising choice.
- Site cookies set by WordPress only if you log in to the site.
You can block or delete cookies in your browser settings. The Slope Finder works without cookies.
Children
Line Slope Finder is written for secondary school, high school and college students, parents and teachers. It is not directed at children under 13, and we do not knowingly collect personal information from them.
Your rights
Depending on where you live, including under the UK GDPR and the EU GDPR, you may have the right to access, correct or delete personal information held about you, and to object to how it is used. Because the Slope Finder doesn’t store your data, we usually hold no personal information about visitors apart from the server logs above. To make a request, email contact@lineslope.com.
