1. About cookies and similar technologies
This Cookie Policy explains how TankFlows, operated by Tianvex International Limited, uses cookies, local storage, pixels, tags and similar browser technologies on our website. These technologies can remember information, support functions, measure performance and, where enabled, help understand communications or campaigns.
A cookie is a small text file a website may place on your device. Local storage is a browser feature that stores information on your device. On this website, local storage is used to remember your cookie preferences. Some technologies may be set by service providers when their services are used.
2. Essential Cookies
Essential technologies support core functions such as security, network delivery, accessibility, preference storage and site operation. The site may not function as intended without them, so they cannot be disabled through our cookie interface.
Current preference record: the key tankflows_cookie_preferences_v1 may be stored locally on your device to remember Necessary, Analytics, Marketing and Preferences choices, plus the date the record was updated.
3. Functional Cookies
Functional or preference technologies remember choices that change how the site behaves or appears, such as language, region, layout or enhanced service options. In our settings interface this category is labelled Preferences. If disabled, some personalised or convenience features may not be available.
4. Analytics Cookies
Analytics technologies help understand how visitors use the site, which pages are useful, whether errors occur and how performance can be improved. Information may include page visits, interactions, device and browser information, approximate region and referring source.
We treat Analytics as optional in the cookie interface. This static release does not need to activate optional analytics simply for core site operation. If analytics services are introduced, they should respond to the choice stored on your device where consent is required.
5. Marketing Cookies
Marketing technologies may help measure campaigns, understand which communications lead to visits, limit repeated messages or support relevant advertising on other services. Marketing partners may recognise a device across websites or apps according to their own notices.
We treat Marketing as optional. Disabling it does not prevent you from using core website content.
6. How long technologies remain
Session cookies generally expire when the browser closes. Persistent cookies and local storage remain until their stated expiry, until replaced or until you remove them through browser controls. The TankFlows preference record remains on the device until browser data is cleared or the record is removed.
7. User control and Cookie Settings
You can select Accept All Cookies, Reject Non-essential Cookies, or customise Analytics, Marketing and Preferences from Cookie Settings. Changing these controls updates the preference record on the device you are using.
You can also block or delete cookies and local storage through browser settings. Browser controls may differ by browser and device. Blocking essential storage may cause settings not to persist. Where third-party opt-out tools are available, you may need to use them separately.
If you clear browser storage, switch browsers or use another device, you may need to make your choices again.
8. Updates to this policy
We may update this Cookie Policy when technologies, services or legal requirements change. The date at the top shows the latest revision.
