What this policy covers
This policy explains cookies, LocalStorage, SessionStorage, consent strings and similar browser technologies used on devicetestbench.com. Device tests process interactive input in browser memory and do not require advertising or analytics storage.
Essential storage
Public test pages do not start a server session. A short, HttpOnly session cookie is used only inside the private administrator area. Theme and consent choices are stored locally in your browser so the interface remembers your decision; these values do not contain test results.
Current first-party storage
The dtb_theme LocalStorage value remembers light or dark appearance until you change it or clear site data. The dtb_consent LocalStorage value records whether optional analytics and advertising gates are allowed, plus the time of the choice, until you revise or clear it. DTBSESSID is a session cookie used only for authenticated administrator security and normally expires when that browser session ends.
When enabled with consent, central analytics may create a random visitor identifier in LocalStorage and a random session identifier in SessionStorage. The visitor value remains until site data is cleared or the service rotates it; the session value is removed by the browser when the session ends. These values must not contain test results.
Optional analytics
Optional analytics may use the stored consent choice to count page or tool events. When the consent-gated central service is enabled, it can store a random visitor identifier in LocalStorage and a random session identifier in SessionStorage, then receive page path, title, referrer, browser language, screen and viewport width, and allowlisted event names. These identifiers are not device-test results.
Analytics is not permitted to receive keys, typed text, pointer coordinates, media samples, frames, recordings, device labels, hardware identifiers or controller input. Rejecting optional storage prevents future analytics loading; clearing this site’s browser data also removes the random identifiers.
Advertising cookies and local storage
Google advertising is not loaded until the site has valid publisher configuration, an eligible page and the required consent signals. When active, Google and participating third-party vendors may use first-party or third-party cookies and similar storage for ad delivery, fraud prevention, frequency limits, measurement and, where permitted, personalization.
Google advertising cookies may be associated with Google or DoubleClick domains and can support ads based on a visitor’s previous visits to this site or other sites. The applicable vendors, purposes and privacy links are presented through the certified regional consent message or vendor list. Device-test inputs are excluded from ad requests.
Certified consent records
For users in the EEA, United Kingdom and Switzerland, personalized advertising requires a Google-certified CMP integrated with the IAB Transparency and Consent Framework. The CMP may store a consent string and related choice records needed to prove, apply or revoke consent. Applicable US-state privacy messages may similarly store regional opt-out or consent choices. The current vendor names, purposes and storage details are shown in that certified interface.
Global Privacy Control and Do Not Track
When the browser exposes an enabled Global Privacy Control or recognized Do Not Track signal, optional Device Test Bench analytics remains off even if an older local analytics preference says otherwise. Advertising choices and legally required regional opt-outs are also governed by the applicable certified privacy message.
Change, reject or clear your choice
Open Cookie Settings at any time to allow selected local categories, reject all optional categories, or clear the saved local decision. If a certified regional advertising message appears, use its privacy options to change purposes and vendors or revoke consent. You can also clear cookies, local storage and site permissions in browser settings. Rejecting optional storage does not disable the device tests.
Third-party controls and updates
Google My Ad Center controls Google ad personalization, and participating industry opt-out services may cover other vendors. Provider controls do not remove the separate first-party choice stored by this site, so use Cookie Settings as well. We update the review date when the storage inventory or purposes materially change and request a new choice when required. Questions can be sent to aicodelab.tony@gmail.com.
