Cookie Policy
Effective date: October 9, 2026. This page lists the cookies and browser storage used on TheSize.net, what each one is for, how long it lasts, and how to control them.
What cookies are
A cookie is a small text file a website asks your browser to store, so that the site or a service it uses can recognize the browser on a later request. First-party cookies are set under the thesize.net domain; third-party cookies are set by another domain, such as an ad network, whose code runs on the page. Similar technologies include local storage, pixels and device identifiers, and this policy covers them too.
TheSize.net does not need any cookie to work. Every guide, table and calculator functions normally if you block all cookies.
Analytics cookies (Google Analytics 4)
We use Google Analytics 4 to count visits and see which guides are read. Its cookies are first-party cookies set by Google's script under our domain.
| Cookie | Purpose | Duration |
|---|---|---|
_ga | Stores a random identifier that distinguishes one browser from another, so visits can be counted as returning or new | 2 years |
_ga_<container-id> | Keeps session state for our Analytics property (here _ga_R8Z83G49GY): session start, session count and engagement | 2 years |
The expiry is reset each time you visit, so both cookies are removed two years after your last visit unless you delete them sooner. To stop Google Analytics on every website, install the Google Analytics Opt-out Browser Add-on.
Advertising cookies
The site is supported by ads served by third-party ad networks, such as Google AdSense and Mediavine, and the advertisers and technology partners they work with. These companies may set their own cookies, or read cookies they set on other sites, to serve ads, limit repetition, measure results, prevent fraud and, with consent where required, personalize ads based on your browsing on this and other websites.
| Cookie | Set by | Purpose | Duration |
|---|---|---|---|
__gads, __gpi | Google (on thesize.net) | Let the site show Google ads and measure ad interactions | 13 months |
IDE | Google (doubleclick.net) | Ad personalization and measurement across sites | 13 months in the EEA, UK and Switzerland; 24 months elsewhere |
test_cookie | Google (doubleclick.net) | Checks whether the browser accepts cookies | 15 minutes |
Other ad partners set cookies with their own names and lifetimes, and the list changes as partners change, so it cannot be given in full here. The consent tool shown to visitors in regions that require it lists the partners active at the time, and lets you accept or refuse each purpose. Durations above are those Google publishes and may change; see How Google uses cookies.
To opt out of personalized ads from Google, use Google Ads Settings. For many other ad companies, use www.aboutads.info (US) or www.youronlinechoices.eu (Europe). You will still see ads, but they will not be based on your activity on other sites.
Local storage: your theme setting
| Key | Type | Purpose | Duration |
|---|---|---|---|
theme | localStorage, first party | Remembers whether you chose the light or dark theme | Until you clear site data |
This value stays in your browser. It is not sent to our servers or to any third party, and it is only written when you use the theme toggle. Without it, the site follows your device's light or dark setting.
Consent
In the European Economic Area, the United Kingdom, Switzerland and other places where the law requires it, analytics and advertising cookies are set only after you give consent through the cookie banner. You can change your choice at any time through the same consent tool. Refusing cookies does not block access to any content; ads may still appear, but they will be non-personalized. US visitors can opt out of the sale or sharing of personal information as described in the privacy policy.
How to manage or delete cookies in your browser
Every browser lets you view, block and delete cookies. Blocking third-party cookies stops most cross-site advertising cookies while keeping the site fully usable.
- Chrome: Settings, then Privacy and security, then Third-party cookies (to block) or Delete browsing data (to clear).
- Safari (Mac): Settings, then Privacy, then Prevent cross-site tracking; use Manage Website Data to remove stored cookies. On iPhone and iPad: Settings, Apps, Safari, Advanced, Website Data.
- Firefox: Settings, then Privacy & Security; Enhanced Tracking Protection set to Strict blocks cross-site tracking cookies, and Cookies and Site Data has Clear Data.
- Edge: Settings, then Cookies and site permissions, then Manage and delete cookies and site data.
Menu names change between browser versions; your browser's help pages have the current steps. Clearing cookies also removes any opt-out cookies you set, so you may need to opt out again afterwards. Clearing site data for thesize.net resets the theme to your device setting.
Changes and contact
We update this policy when we add or remove a service that uses cookies, and change the effective date above. Questions: [email protected]. How the data collected by these cookies is used, and your rights over it, are covered in the privacy policy.
