Cookies Policy

This Cookies Policy explains how Tamcalc Limited trading as MarketSizer ("MarketSizer", "we", "us", or "our") uses cookies and similar technologies when you visit our websites at marketsizer.io and any related subdomains (the "Websites"). It sits alongside our Privacy Policy, which describes how we collect and use Personal Information more generally.

What cookies are

Cookies are small text files that a website places on your device when you visit it. They let the site remember your choices, measure how the site is used, and, for some categories, support advertising. We also use similar technologies such as web beacons, pixels, and local storage; for simplicity, this page refers to all of them as "cookies".

How we categorise cookies

We group cookies into three categories. Necessary cookies are always on because the site cannot function without them. Analytics and marketing cookies are off by default and only set after you opt in through our cookie banner.

• Necessary - required for the site to load, route, and remember your cookie preferences. Cannot be disabled.
• Analytics - help us understand how visitors use the site so we can improve it.
• Marketing - help us measure the performance of our advertising and, where applicable, retarget visitors on other platforms.

Our cookie inventory

The table below lists every cookie and similar identifier the Websites set, who sets it, what it is used for, and how long it persists. We review this list whenever we add or remove a vendor.

Third-party cookies in the analytics and marketing tables are set by the named processors under their own privacy policies. Where we receive any data back from them, we handle it in line with our Privacy Policy.

Google Consent Mode v2

Before you make a choice in our cookie banner, we run Google Consent Mode v2 with analytics_storage, ad_storage, ad_user_data, and ad_personalization all set to denied. That means Google's tags load in a restricted mode that does not write identifying cookies or send personal data until you opt in. If you reject analytics or marketing, those signals stay denied for the rest of your session.

How to manage your choices

You can change your cookie choices at any time:

• Click Cookie Settings in the footer of any page. This re-opens the consent banner with your current choices selected, and you can accept, reject, or fine-tune each category.
• Use your browser's built-in cookie controls to block or delete cookies. Most browsers let you do this per-site under "Privacy and security" or "Site settings". Note that blocking necessary cookies will break parts of the site.
• For Google Analytics specifically, you can install Google's opt-out browser add-on.

If you are located in the United Kingdom or the European Economic Area, our analytics and marketing categories are strictly opt-in and remain off until you actively accept them. If you are located in a US state with an opt-out privacy law (California, Colorado, Connecticut, Utah, Virginia, and others), you can use the same Cookie Settings link to opt out of marketing cookies; this is the mechanism we use for "Do Not Sell or Share My Personal Information" requests.

Changes to this policy

We may update this Cookies Policy from time to time when we add or remove a vendor, or when the law requires changes. The "Created" date at the top of this page reflects the most recent change. Material changes will be communicated through the cookie banner where appropriate.
