Privacy Policy
Last updated:
This policy explains what information calcclassroomtips.com collects, why it is collected and what choices you have. It is written to describe the site as it actually operates. It is not legal advice, and it does not create contractual obligations beyond what applicable law requires.
Information you provide
This site does not require an account and does not ask you to submit personal information to read a tutorial. If you contact the site owner by email at testat@qq.com, the address you write from and the contents of your message are received and kept only for as long as needed to answer you.
Information collected automatically
Like most websites, the server and any content delivery network in front of it record standard technical data when a page is requested — for example the page requested, the time of the request, the referring page, an approximate location derived from your IP address, and the browser and device type reported by your browser. This is used to serve pages correctly, detect abuse and understand which guides are useful.
Cookies and similar technologies
Cookies are small files stored by your browser. This site itself sets no cookies that identify you personally. Third-party services used on the site may set their own cookies, and you can block or delete cookies in your browser settings at any time without losing access to the tutorials.
Advertising
Advertising displayed on this site is served by Google and its partners. Google may use cookies and device identifiers to serve ads based on your visits to this and other websites. You can control personalised advertising in your Google Ads settings, and you can opt out of personalised advertising from many providers through the industry opt-out pages linked from your ad settings. See the ad disclosure for how advertising is placed on this site.
Analytics
Aggregate statistics may be collected to measure page views, traffic sources and general visitor location. These statistics are reported in aggregate and are not used to build a profile of an individual reader.
Affiliate links
Some links to retailers are affiliate links. If you click one and make a purchase, the retailer may record that the visit came from this site and report that fact to us without identifying you. Details are in the affiliate disclosure.
Children
This site is intended for a general audience of students, teachers and parents and is not directed at children under 13. We do not knowingly collect personal information from children.
Your choices and rights
Depending on where you live, you may have rights to access, correct or delete personal data held about you, and to object to certain processing. Requests can be made by email at testat@qq.com. Requests relating to advertising cookies are handled most efficiently through your Google Ads settings and your browser's cookie controls.
Changes to this policy
This policy may be updated to reflect changes in the services used on the site. The date at the top of the page always shows the current version.
