What Cookies Are
Cookies are small text files stored on your device when you visit a website. They help websites function correctly, remember your preferences, analyze performance, and support advertising. Similar technologies include pixels, tags, scripts, and local storage. ProofMatcher uses a combination of these technologies, described below by category.
Essential and Functional Cookies
These cookies are required for the website to operate. They include session cookies that maintain your login state after signing in with Google, security cookies that protect against cross-site request forgery and other threats, cookies that support the checkout and payment flow with Stripe or PayPal, and the cookie preference record that stores your consent choices. Essential cookies cannot be disabled without breaking core site functionality.
Analytics Cookies — Google Analytics
We use Google Analytics 4 (GA4) to collect anonymized data about how visitors use ProofMatcher. GA4 may set cookies such as _ga and _ga_* to distinguish users, track sessions, and measure engagement. Data collected includes pages visited, events triggered, session duration, browser and device type, and approximate geographic location. IP addresses are anonymized before collection. You can opt out of Google Analytics using the browser add-on at https://tools.google.com/dlpage/gaoptout.
Advertising Cookies — Google AdSense
We use Google AdSense to display advertisements on ProofMatcher. Google AdSense (operated by Google LLC) and its advertising partners may set cookies to deliver relevant ads, measure ad impressions and clicks, and build an interest profile based on your browsing activity across websites. Depending on your region and consent settings, ads may be personalized or non-personalized. You can manage Google ad personalization at https://adssettings.google.com. You can also opt out of interest-based advertising from many ad networks at https://optout.networkadvertising.org. Opting out does not remove ads — it means ads may be less relevant to your interests.
Preference and Session Cookies
These cookies store your browsing preferences and session state during your visit to ProofMatcher. This includes your cookie consent decision (stored in your browser's local storage under the key proofmatcher_cookie_consent), any user interface preferences, and temporary session identifiers. These cookies do not track you across other websites.
Managing Cookie Preferences
You can manage your cookie preferences at any time using the cookie settings button in the bottom-left corner of the website. You may choose to accept all cookies, reject optional cookies, or customize your preferences for analytics, marketing, and personalization categories. Most browsers also allow you to view, block, or delete cookies through browser settings. Note that disabling certain cookies may affect website functionality. Browser-specific instructions: Chrome (Settings → Privacy and Security → Cookies), Firefox (Settings → Privacy & Security), Safari (Preferences → Privacy), Edge (Settings → Cookies and site permissions).

We are happy to clarify how specific cookies work, what data they collect, and how long they are stored. You can also review our full Privacy Policy for more details about how your data is handled.
