This Cookie Policy explains which cookies and similar technologies Printer Test Lab uses, what they do and how you can control them. It complements our Privacy Policy.
What cookies and local storage are
Cookies are small text files a website stores in your browser. Local storage is a similar browser feature that keeps data on your device. Both can be “first-party”, set by the site you visit, or “third-party”, set by another company whose services appear on the site.
Our own storage: two preferences
We don’t set cookies of our own. We store two preferences in your browser’s local storage so the site remembers your choices:
| Name | What it stores | Duration |
|---|---|---|
ptl-paper |
Your paper size choice, Letter or A4 | Until you clear your browser’s site data |
ptl-theme |
Your light or dark mode choice | Until you clear your browser’s site data |
These values never leave your device and aren’t used to identify or track you. They’re set only when you choose a paper size or theme, so they’re part of a feature you requested and don’t require consent. If your browser blocks storage, the site works the same way; it just won’t remember your choice.
Third-party cookies: advertising from Google
The site shows ads from Google AdSense. Google and its partners may use cookies and similar technologies to:
- show ads, and personalize them based on your visits to this and other websites, where you allow it;
- limit how often you see an ad and measure how ads perform;
- detect and prevent fraud and abuse.
The exact cookies depend on your location, your consent choices and the ads shown. Google lists them and explains their purposes in Types of cookies and other technologies used by Google and How Google uses cookies in advertising.
Your consent
If you visit from the European Economic Area, the United Kingdom or Switzerland, Google’s certified consent message asks for your choice before non-essential advertising cookies are used. You can accept, refuse, or choose purposes and partners one by one, and change your mind at any time with the Privacy and cookie settings link at the bottom of every page. In some US states, Google’s message also lets you opt out of the sale or sharing of personal information for advertising.
Opting out of personalized ads
Wherever you are, you can turn off personalized ads from Google in Ads Settings, and opt out of personalized ads from many other companies at www.aboutads.info.
Controlling cookies in your browser
You can also block or delete cookies and site data in your browser’s settings. Blocking third-party cookies stops personalized ads but doesn’t stop the site from working. The help pages of your browser explain how:
