Clarity OS LLC
Clarity OS intentionally minimizes cookies and tracking. We use only what is needed to keep you signed in, keep the product reliable, understand how our website is performing, and learn which of our ads and posts bring people here. Nothing more.

Cookies are small text files that websites place on your device. They help websites remember information about your visit — for example, whether you are signed in. Clarity OS also uses a small amount of browser storage for similar purposes, which we describe below.
Clarity OS uses a small number of cookies. All but one are essential to how the service works. The exception is a campaign-tag cookie, described under Ad Campaign Tags below, which is set only when your browser blocks local storage.
When you sign in, we use session cookies to keep you authenticated, protect your account, and allow the website to function securely while you use Clarity OS. Without these cookies, you would need to sign in again on every page.
These cookies are strictly necessary for account access and security. They are not used for advertising or to track you across other websites.
We use Vercel Web Analytics to understand how our website is used and to improve performance and reliability. This helps us see which pages are visited and general information about device type and browser — always in aggregate.
According to Vercel, this analytics service does not use cookies and does not track you across different websites. Before analytics data leaves your browser, Clarity OS removes sensitive information from page URLs, such as tokens or reset codes that might appear in query parameters.
In addition to cookies, Clarity OS stores a small amount of information locally in your browser. This helps the web app stay responsive — for example, while a protection session is starting or if your connection is briefly interrupted.
This local browser data is a convenience cache only. Your active and scheduled Protection Windows are stored securely on our servers and continue on your paired devices. Signing out clears this local browser cache, but it does not cancel, pause, or weaken your Protection Windows.
On the beta application page, we also create a random progress identifier and keep it in session storage for that browser tab. We use it to connect page, Apply-button, question-view, and submission events without putting your name, email address, or answer text in those events. The identifier is removed when the tab session ends or when you clear the site's data. The server-side progress events are automatically deleted after 90 days.
For more about how we handle personal information across Clarity OS, see our Privacy Policy.
When you arrive through one of our ads or tagged links, the website remembers where you came from: the campaign tags in the link (such as utm_source and utm_campaign), the click ID that Instagram or Reddit adds to ad links (fbclid or rdt_cid), the name of the site that sent you (never the full page address), the first page you landed on, and when.
These details are kept in your browser's local storage. If your browser blocks local storage, they are kept instead in a first-party cookie named clarity_first_touch. Either way they expire after 90 days and are not replaced by later visits. If you join the waitlist or apply to the beta, they are saved with your sign-up so we can see which ads and posts work. They are never sent to Meta, Reddit, or any other ad network.
Clarity OS is built with a privacy-first mindset. We intentionally keep tracking technology to a minimum.
Apart from the first-party campaign tags described above, which stay with Clarity OS, Clarity OS does not currently use advertising cookies, social media tracking pixels, cross-site profiling technologies, or third-party marketing cookies. We do not sell your data to advertisers, and we do not use cookies to follow you around the internet.
You can control cookies through your browser settings. Most browsers let you block or delete cookies, or clear site data entirely.
You can also sign out of Clarity OS at any time. Signing out ends your authenticated session and clears local browser cache used for the web dashboard. It does not stop active Protection Windows or change your schedules. Blocking essential cookies may prevent you from signing in or using account features.
If you use Clarity OS on desktop, mobile, or through our browser extension, those apps may store information on your device to keep protection working reliably. Those experiences are covered in our Privacy Policy.
We may update this Cookie Policy from time to time — for example, if we add new features or change how we use cookies or analytics. When we do, we will post the updated policy on this page and revise the date below.
