This page explains the small files this website puts on your device, what each one is for, and how to change your mind about them. It is written plainly on purpose. If anything here is unclear, please ask and it will be explained.
This website is run by ReelSlinger Limited, company number 11057267, trading as Oxbridge GCSE Tutor. What happens to your information more generally is set out in the privacy policy, which is a separate page.
What a cookie actually is
A cookie is a small text file that a website asks your browser to keep. The next time you visit, the website can read it back. That is the whole trick. It is how a site remembers that you already chose “reject”, so it does not ask you again on every single page.
Some other things work the same way without technically being cookies, such as small notes stored in your browser’s own memory. The law treats them all the same, and so does this page. When this page says “cookie”, it means all of them.
Cookies cannot run programs, and they cannot read anything else on your computer. The reason they matter is not that they are dangerous. It is that some of them let a company recognise you again later.
The short version
Three groups, and only one of them is up to you.
- The ones the website needs to work at all. These load whatever you choose, because without them the site breaks. There are only a few and they do not follow you anywhere.
- The four that wait for your permission. Two of them measure how the site is used, one shows our review stars, and one plays the videos. None of the four loads at all until you press Accept. If you press Reject, none of them ever starts. You can change your mind later, in either direction.
- One counter that uses no cookies whatsoever. It only produces totals, such as “412 people read this page last week”. It cannot tell one visitor from another. You can still switch it off if you want to.
Refusing is exactly as easy as accepting. If you refuse, the videos and the review stars do not load, because those are two of the four. Everything that matters still works: you can read every study guide, send an enquiry, book a lesson and be taught.
Group 1: the ones that keep the website working
These load automatically. The law does not require permission for them, because the site genuinely cannot work without them.
| What it is for | Who runs it | Roughly how long it lasts |
|---|---|---|
| Remembering your cookie choice, so you are not asked again on every page | This website | 365 days. The cookie is called ogt_consent and it belongs to this website only. All it holds is the date you chose, a version number, and a yes or no for each of the four optional tools. No name, no address, nothing that identifies you |
| Remembering that you turned visit counting off, so it stays off on every page and when you come back | This website | 365 days. The cookie is called ogt_ahrefs and it belongs to this website only. It is only written if you use the switch described in Group 3. All it holds is the date you chose, a version number, and a yes or no. No name, no address, nothing that identifies you |
| Checking that you are a person rather than a robot, before the page is handed over | SiteGround, the company that runs the computers this website sits on | 30 days. The cookie is called _I_ and it belongs to this website. It holds one meaningless string of letters and numbers, which records that the security check let you through, so you are not checked again on every page. It is not always set: it appears when the check actually runs. Your browser will not let any script read it |
| Protecting the site from attacks and telling real visitors apart from automated traffic | Cloudflare | No cookie from Cloudflare on this website itself. Three pages of the live site were loaded with the browser tools open and Cloudflare put nothing on this address. The one Cloudflare cookie that did appear is __cf_bm, and it was set by the two NitroPack addresses that serve our images and files, nitrocdn.com and getnitropack.com. It lasts 30 minutes and its job is to tell a real person apart from a robot. If Cloudflare ever has to stop and challenge a visitor it thinks is a robot, it can also set one called cf_clearance, but that did not happen in the check |
| Making pages load faster, by serving a ready-made copy of the page | NitroPack | One cookie, called nitroCachedPage. It belongs to this website, all it holds is a single digit, 1 or 0, saying whether the page you were shown came from the ready made copy, and it is a session cookie, which means your browser throws it away the moment you close it. NitroPack also keeps a note called nitroScrollPos in your browser’s own memory, remembering how far down a page you had scrolled. That note is thrown away when you close the browser too |
| The website’s own housekeeping | This website | Nothing that identifies you, and nothing that leaves your device. The page builder keeps a note called elementor in your browser’s memory, holding two numbers, how many pages you have looked at and how many visits you have made, plus a flag saying this visit is still going. WordPress keeps one called wpEmojiSettingsSupports, which only records whether your browser can draw emoji. Neither is sent anywhere and neither follows you to another website |
These do not follow you to other websites, and they are not used to work anything out about you. They cannot be switched off from the banner, because switching them off would break the site. You can still block them in your browser settings if you want to, and the section at the bottom explains how.
Group 2: the ones that only start if you say yes
There are four of them, and none loads until you press Accept on the cookie banner. Not one. If you press Reject, they are never downloaded, so they never put anything on your device and never see your visit.
| Tool | Who runs it | What it does | How long the information is kept |
|---|---|---|---|
Google Analytics, measurement ID G-78CGGCYK0V |
Counts visits and page views, tells us roughly where in the world visitors are, and which pages they read. It puts a small file on your device so it can tell a returning visitor from a new one | Event data: 2 months. Information tied to an individual visitor: 14 months. Then Google deletes it. Verified from the account settings on 12 August 2026. The cookies on your own device: _ga and _ga_78CGGCYK0V, both belonging to this website rather than to Google. Google’s own help page says they are meant to last 2 years. What was actually measured in the browser is 400 days, because Chrome shortens every cookie of this sort to 400 days and Safari shortens it to 7 days. So 400 days is the real figure for most people |
|
Hotjar, site ID 6417241 |
Hotjar Ltd | Records what happens on screen during a visit, meaning mouse movements, scrolling and clicks, and combines many visits into a colour map showing which parts of a page people look at | 365 days from the moment of the visit, then deleted. This is the same on every Hotjar plan. The cookies on your own device: _hjSessionUser_6417241, which lasts 365 days, and _hjSession_6417241, which lasts 30 minutes. Both belong to this website rather than to Hotjar. Hotjar also keeps two short notes in your browser’s own memory, hjActiveViewportIds and hjViewportId, which hold the same visit id. One is thrown away after about six hours and the other when you close the browser |
| YouTube, the player for the videos on this site | Plays the videos embedded on this site. The player does not load at all until you press Accept, and even then nothing loads until you click play. The embeds use YouTube’s no-cookie version, so until you click, nothing about you goes to YouTube at all | Nothing until you click play. After that, the no-cookie player still needs a small amount of storage on your device to play the video. None of it is used for advertising | |
| Trustindex, the review stars | Trustindex | Shows our Google review stars on the page. It does not load at all until you press Accept, so until then nothing about your visit reaches it | Nothing at all. The review stars were loaded with the browser tools open and Trustindex left no cookie, and stored nothing in the browser’s own memory either. It does have to fetch the reviews from its own servers, and the reviewers’ photographs come from Google, so both companies can see that your browser asked for them. Nothing is left on your device afterwards |
Hotjar is the one worth reading twice
Hotjar records an individual visit rather than just counting it. That is a real difference, and it is exactly why we ask permission first and why refusing is as easy as agreeing. The UK regulator names session recording specifically as something you must have permission for.
Two things about Hotjar are better than people expect, and they are worth knowing:
- Anything you type is blocked before it ever reaches Hotjar. Not sent and then hidden afterwards. Blocked in your own browser, so the words never leave your device. If your child types into a form on this site, those words do not go to Hotjar at all.
- Your IP address is not stored. It is used in passing to work out roughly what part of the world a visit came from, and then it is not kept. So a recording is not tied to your address.
Why Google Analytics is behind the banner too
Some websites let their analytics run before you have said anything. This one does not. Until you press Accept, Google Analytics does not start and your visit is not counted by it.
The UK rules changed on 5 February 2026, and plain visitor counting no longer always needs permission. Google Analytics is not plain visitor counting. It gives each visitor a lasting ID and hands the information to Google, who also use it for their own purposes. The honest answer is to ask, so we ask.
Group 3: the counter that uses no cookies
Ahrefs Web Analytics counts visits and page views so we can see which study guides are useful and which nobody reads. It uses no cookies and no lasting identifiers of any kind. It cannot recognise you, follow you between visits, or tell one visitor from another. It only produces totals.
The banner does not ask you about this one, and it does not mention it. The banner covers the four tools in Group 2 and nothing else. Ahrefs starts on its own, on every page, without anybody being asked. So this page and the privacy policy are where you are told about it, and there is a switch that turns it off.
UK law allows plain counting like this without asking first, on two conditions: we have to tell you it is happening, and we have to give you a simple, free way to say no. So here is the way to say no: turn visit counting off on the privacy policy page. The switch lives there and nowhere else, so there is only ever one thing to change.
That is the whole process. It is free, it is one click, we do not ask why, and nothing else on the site changes.
The chat assistant on the homepage
There is a talking chat assistant on the homepage, run by a company called ElevenLabs. It is not a cookie, but it belongs on this page because it stores things about you if you use it.
- It asks your own permission before it starts, in its own box, separately from the cookie banner.
- If you use it, what you say or type, any file you attach, and the audio of your voice go to ElevenLabs so it can answer you. They keep a copy for 730 days, which is two years, and then delete it. The information is held in the United States.
- If you do not use it, nothing is stored. Nothing else on the site depends on it, and the enquiry form, email and telephone all work exactly the same.
Please do not type or say anything private into it. If you want to tell us something personal about your child, use the enquiry form or email instead. There is more about the chat assistant in the privacy policy.
How to change your mind
You can change your choice at any time, in either direction, and it takes one click.
- On this page: press and the same box opens again, with your current choices already ticked. Change whatever you like and it takes effect straight away. If you switch something off that had been on, the page reloads so that tool genuinely stops, rather than carrying on until you leave. This page is the only place that link lives, and that is deliberate. A button parked in the corner of every page would follow you around the site for ever, and the banner already offers you Choose the first time you arrive. So the way back is here, on the page that explains what you are choosing between.
- In your browser: every browser lets you block or delete cookies for a website, and that works whatever we do. In Chrome, Safari, Firefox and Edge it sits in settings, under privacy. Deleting this site’s cookies also deletes the record of your choice, so you will be asked again next time.
- Turning off the cookieless counter is separate, because it never used a cookie in the first place. Use the link in Group 3 above.
Nothing on this site is withheld from you for saying no. There is no reduced version of the site, no nagging, and no repeated asking.
What we never do
- We do not advertise to anybody on this site, and none of these tools is used to target adverts.
- We do not sell information about visitors, to anybody, ever.
- We do not build profiles of children. Children aged 11 to 16 read the free study guides here, and the revision pages ask them for nothing at all: no account, no sign-up, no details of any kind.
- We do not use any of this to make a decision about you. Stephen reads every enquiry himself.
If this page changes
If we add a tool that watches how you use the site, or change what an existing one does, this page is updated, the date at the top changes, and you are asked again through the banner. A new tool does not get to ride in on permission you gave for a different one.
How to ask about any of this
Email: [email protected]
Stephen reads the inbox himself. If you would rather complain to the regulator, the privacy policy explains how to contact the Information Commissioner’s Office, which is free and does not require speaking to us first.
