Cookie policy
This site sets two cookies, both belonging to Google Analytics and both used to measure the audience. No advertising system is present and no other third party script is loaded. Two further preferences may be stored in your browser's local storage, and neither one ever leaves your device.
Cookies set by this site
Two, both set by the audience measurement described below. Refusing the measurement stops them being set, and the control that does so is further down this page.
| Name | Purpose | Lifetime | Issuer |
|---|---|---|---|
_ga | Distinguishes one browser from another so that a returning visit is not counted as a new one | Two years | |
_ga_ followed by the property identifier | Keeps the state of the current session | Two years |
Local storage
Local storage is not a cookie: it is never attached to a request, so it is not transmitted to any server. This site uses it for two preferences, both listed in the privacy policy: the theme you chose, and your refusal of the audience measurement.
Audience measurement
This site uses Google Analytics 4. The script is loaded from googletagmanager.com, the two cookies above carry the identifier it needs, and what is collected is described in the privacy policy.
The control below stops it for this browser. The refusal takes effect at once and holds on every page of the site until you withdraw it or clear your browser data.
Third party content
The Google Analytics script is the only file this site loads from another domain. No font, image or frame comes from anywhere but nfc.guide. Guides link out to sources such as the NFC Forum, GS1 and the app stores, but a link transmits nothing until you follow it.
If this changes
This page and the privacy policy were rewritten before the measurement was switched on, as they undertook to be. Any further cookie would be added to the table above, with its purpose, its lifetime and its issuer, under the same rule.
