Watching the Mara River Crossings: A Guide to the Northern Serengeti
The Mara River crossings in the northern Serengeti usually fall between July and October. Why the herds cross, how long you may wait, and why they can never be guaranteed.
What this website stores in your browser, why, and how to control it.
This summary is for convenience only. The full text below is what applies.
This Cookie Policy explains what The Expedition Tours stores on your device when you visit our website, why we store it, and how you can control it. The Expedition Tours is a business name registered with BRELA in Tanzania (Business Name No. 717897), and our postal address is P.O. Box 7037, Arusha, Tanzania. We arrange safaris, Kilimanjaro climbs and Zanzibar holidays, and this website is where many of our guests first meet us.
We have written this policy in plain English because we believe you should be able to understand exactly what happens in your browser without needing a technical background. The honest summary is a short one: this website is deliberately very light on storage. We keep two small notes in your browser, one for your choice in our cookie notice and one for the language you pick, and analytics set cookies only if you accept them.
In this policy, 'we', 'us' and 'our' mean The Expedition Tours, and 'the website' means theexpeditiontourstz.com and its pages. 'You' means anyone who visits the website. If a word in this policy is unfamiliar, the glossary near the end explains it.
Cookies are not the only way a website can keep information in your browser. Modern browsers also offer local storage, session storage and other tools that let a website save small pieces of data on your device. Unlike a cookie, data held in local storage is not automatically sent to the website's server every time your browser requests a page. It stays on your device and is read only by the website's own code running in your browser.
Other technologies in the same family include web beacons or pixels (tiny invisible images used to count visits or measure advertising), device fingerprinting (combining technical details about your device to recognise it without storing anything) and software development kits inside mobile apps. Privacy law generally treats all of these in much the same way as cookies, because they can all be used to recognise you or your device.
When this policy says 'cookies', it therefore includes local storage and similar technologies, even where the item we store is technically not a cookie. This is important because our one stored item sits in local storage rather than in a cookie, and we want to be completely open about it.
The table below lists everything this website stores in your browser. It is a complete list, not an example. If an item is not in this table, we do not store it.
The consent flag is set when you click 'Accept analytics' or 'Decline' on the cookie notice. It records only which of the two you chose. It holds no personal information: no name, no email address, no identifier that points to you, and no record of the pages you view.
| Name | Where it is kept | Purpose | What it contains | How long it lasts |
|---|---|---|---|---|
| expedition_cookies_consent | Local storage in your browser | Remembers that you have seen and dismissed the cookie notice, so that we do not show it to you again on every page | A simple flag showing the notice was dismissed. No personal information | Until you clear your browser data |
The website sets one cookie of its own: expedition_locale, which remembers the language you choose and lasts one year. There are no sign-in cookies, no basket cookies and no cookies that remember your pages or searches. Apart from that cookie and the consent flag, we place nothing on your device unless you accept analytics.
Showing a notice every time you open a page would be irritating and would make the website harder to use. The flag lets us show the notice once and then step out of your way. Because it exists only to support the notice itself, and does nothing to identify or follow you, we treat it as strictly necessary for the website to work properly.
Cookies are usually grouped by what they do. The table below explains the four common categories and says plainly whether this website uses each of them. Knowing the categories helps you judge the notices you meet on other websites too.
| Category | What it does | Examples elsewhere | Does this website use it? |
|---|---|---|---|
| Essential (strictly necessary) | Makes a website function, or remembers a choice you have asked it to remember. Websites usually do not need your permission for these | Keeping items in a basket, keeping you signed in, remembering that a notice was dismissed | Yes, in a minimal form: the expedition_cookies_consent flag in local storage |
| Preferences (functional) | Remembers settings such as language, currency or region so that you do not have to choose again | Remembering a chosen language or text size | Yes, one: the expedition_locale cookie, which remembers the language you chose for one year |
| Analytics (performance) | Counts visitors and shows which pages are viewed, so the owner can see how a website is used | Visitor counters, page view reports, heat maps | Cookies only if you accept it. If you decline, analytics run in a restricted mode with no cookies and no stored identifiers |
| Advertising (marketing) | Builds a profile of your interests and shows you targeted advertisements, often across many websites | Advertising network cookies, retargeting pixels, social media pixels | No. We use no advertising or marketing technologies |
A first-party item is set by the website you are visiting. A third-party item is set by someone else whose service is built into the page. The difference matters for privacy, because third-party items are the usual route by which activity is followed across different websites.
The consent flag and the language cookie are first-party: we set them, we read them, and they never leave your browser. Google Tag Manager and the analytics tools we run through it are third-party services: your browser contacts Google's servers on every page, and if you accept analytics they may also store cookies or similar data in your browser. We do not allow any third party to set cookies or store data on our behalf for advertising or tracking.
Even without cookies, a web page is often assembled from several sources. When you open this website, your browser retrieves some resources from other organisations, and those organisations can see technical information such as your IP address, because that is how any request over the internet works.
These providers act as part of the technical infrastructure that makes the website load. We do not use them to profile you or to show you advertising. Each provider has its own privacy practices, which you can read on its own website.
Our principle is simple: we should collect only what we need to serve you, and we should be open about it. A guest planning a safari or a Kilimanjaro climb is trusting us with an important and often costly decision. That trust is not helped by a website that quietly watches visitors.
For that reason, analytics cookies are set only with your permission, and the website does not use advertising technologies, social media pixels, session replay tools (which record how a visitor moves a mouse and types on a page) or any tracking across other websites. We do not build profiles of visitors, and we do not sell or share browsing information with advertisers.
If you accept analytics, we see in aggregate which pages are visited and how the site performs, so that we can improve it. If you decline, analytics run in a restricted mode without cookies, so we only get limited, anonymous counts, and we rely on conversations with our guests and the feedback they choose to give us.
When you first visit the website, a short cookie notice appears. It tells you what we store and links to this policy. It asks whether you accept analytics. When you click 'Accept analytics' or 'Decline', the website saves your choice in the consent flag so that the notice does not appear again.
Analytics cookies are optional, so the notice is a request for your permission: no analytics cookies are set until you click 'Accept analytics', and you can decline without losing access to any part of the website. We never use advertising or cross-site tracking.
If you do not click the button, the notice may continue to appear on your visits. Nothing else changes, and you can keep using the website.
You can remove the consent flag at any time. Doing so will simply cause the cookie notice to appear again the next time you visit, which gives you the chance to read it afresh. You can also change your choice at any time with the 'Cookie settings' link in the footer of every page.
To remove it, clear the site data for this website in your browser. The steps for common browsers are set out in the next section. You can also use your browser's private or incognito mode, in which stored data is normally discarded when you close the window.
Because we use nothing else, the 'Cookie settings' link is the only setting to change. There is no account to close and no other preference centre to visit.
Every major browser lets you see, block and delete cookies and site data. The table below gives the general route in popular browsers. Browser makers change their menus from time to time, so the exact wording may differ on your version. If you cannot find a setting, use the search box in your browser's settings, or visit the browser's help pages.
Look for the option called 'Site data', 'Cookies and site data' or 'Website data', because local storage is normally listed together with cookies there. Clearing all site data removes the data of every website, not only ours, so you may be signed out of other services. Deleting only the entry for this website is the gentler choice.
| Browser | General steps |
|---|---|
| Google Chrome | Open the three dot menu, choose Settings, then Privacy and security, then Third-party cookies or Cookies and other site data. Use 'See all site data and permissions' to find this website and delete its data |
| Apple Safari (Mac) | Open the Safari menu, choose Settings (or Preferences), then Privacy. Select 'Manage Website Data', search for this website and choose Remove |
| Mozilla Firefox | Open the menu, choose Settings, then Privacy and Security. Under 'Cookies and Site Data', choose 'Manage Data', search for this website and choose 'Remove Selected' |
| Microsoft Edge | Open the three dot menu, choose Settings, then Cookies and site permissions, then 'Manage and delete cookies and site data'. Choose 'See all cookies and site data' to find and remove this website |
| iPhone and iPad (Safari) | Open the Settings app, scroll to Safari, then choose Advanced and Website Data. Search for this website and swipe to delete, or choose Clear History and Website Data |
| Android (Chrome) | Open Chrome, tap the three dot menu, then Settings, then Privacy and security. Choose 'Delete browsing data', select 'Cookies and site data' and confirm |
Blocking or deleting what this website stores will not stop you reading our pages, requesting a quote or contacting us. The only visible effect is that the cookie notice will appear again, because the website will no longer remember that you dismissed it.
On other websites the effects of blocking can be more significant. You may be signed out, lose items in a basket, or have to re-enter settings. If you choose to block storage across your whole browser, it is worth knowing that some sites may not work as you expect.
Some browsers can send a signal with each request to say that you do not wish to be tracked. Two are common. Do Not Track (DNT) is an older, widely supported setting. Global Privacy Control (GPC) is a newer signal designed to carry a clear opt-out request that some privacy laws recognise.
Analytics cookies are set only if you accept them in the cookie notice, and the website does not follow you across other websites. We respect these signals in spirit: whether or not your browser sends one, we do not build advertising profiles or sell your browsing data. If you prefer, decline analytics in the cookie notice, or change your choice with the 'Cookie settings' link in the footer.
Our pages contain links to other places, including WhatsApp, which many guests use to message us, and other websites such as destination information pages. When you follow a link, you leave our website, and the other site may use its own cookies and similar technologies.
We do not control those sites and are not responsible for their practices. Please read their cookie and privacy policies before you share information with them. Opening WhatsApp, for example, is governed by WhatsApp's own terms and policies.
This website is intended for adults planning travel. It is not aimed at children, and we do not knowingly collect information from them. The single item we store does not identify anyone, including a child. If you are a parent or guardian and have a concern about information relating to a child, please write to us using the details below and we will help.
We may one day wish to understand our website better, for example to see which pages are most helpful. If we decide to do this, we will follow a clear process before anything is switched on.
These plain definitions may help you read this policy and similar notices elsewhere.
Not unless you accept analytics, apart from the expedition_locale cookie that remembers your language. We also keep one small item, the expedition_cookies_consent flag, in your browser's local storage to remember your choice. If you accept analytics, Google Tag Manager and the analytics tools we run through it may also store cookies.
Not across websites. Analytics measure how the site is used, in aggregate: with cookies if you accept, in a restricted mode without cookies if you decline. We use no advertising, social media pixels, session replay or tracking across other websites.
No. It records only that the notice was dismissed. It contains no name, email address or identifier, and nothing in it relates to the pages you visit.
The notice returns if you have not clicked 'Accept analytics' or 'Decline', if you cleared your browser data, or if you are using a private window that discards data when closed. It also appears if your browser blocks local storage, because the website cannot then remember your choice.
Yes. You can read every page and contact us whether or not you click the button.
Yes. We will update this policy before adding anything new, and we will ask for permission where the law requires it.
If you have a question about this policy, or about what the website stores, please contact us. We will reply as soon as we reasonably can.
We may update this Cookie Policy from time to time, for example if we change what the website stores, if the law changes, or if we want to explain something more clearly. When we make a change, we will update the policy on this page and show the revised version. If a change is significant, we will take extra steps to bring it to your attention, such as showing the cookie notice again.
We encourage you to look at this page now and then. Your continued use of the website after a change means you have had the chance to read the updated policy, but where the law requires your permission for a new use, we will ask for it rather than assume it.
