We want to be clear about what sorts of information we gather about you. Broadly speaking, we collect info needed to help us fulfil our accounting requirements to the government (your address, your country as calculated from your IP address), information to help us determine appropriate special offers (e.g. we guess what subject you study and what year you are in based on your browsing history), information to provide our tutoring service (without your address and subject, it would be impossible to pair you), information to facilitate customer service (e.g. by comparing IP addresses of accounts, we can determine when a customer has accidentially created a second account without their downloads due to a typo), information to combat fraud (e.g. we monitor how often files were downloaded, and from what IP addresses, in order to build cases for fighting credit card fraud), and information to help us determine statistical trends with our business (e.g. what pages you viewed, as seen through Google Analytics).
Like many other web sites, we make use of log files and Google Analytics. The information inside both includes IP addresses, geographic data, types of browsers, Internet Service Providers (ISP), date/time stamps, referring/exit pages, and number of clicks. We use these primarily to debug our codebase, improve our website's speed, and analyse broad trends as to inform management in making decisions about the business's future strategy.
As with most other websites using Paypal, Paypal automatically provides us with your real name and shipping address. We use this information for mandatory taxation and accounting purposes.
We let third party advertising companies track whenever you have visited Oxbridge Notes and its affiliated websites. We also use identifying information (such as your email address) to create custom advertising lists. Both of these sources of information are used to redisplay advertisements to you on other websites, such as Google, Facebook, Twitter, and websites affiliated with the aforementioned.
We use conversion tracking to track whenever you have done certain commercially valuable actions on our website, chiefly when you have made a purchase. This conversion information is later used by us to figure out what advertising campaigns were effective in triggering this sale. Conversion tracking is done in association with a third party advertising provider (e.g. Twitter, Facebook, Google), who also have access to the data.
We save all enquires made via either via our main contact form or via the queries sent to individual authors. We do this for business analysis, monitoring author responsiveness to consumer requests, and policing transactions that are against our terms of services.
