5. Log Files
SH Helper follows a standard procedure of using log files. These files log visitors when they visit websites. All hosting companies do this as part of hosting services' analytics. The information collected by log files includes internet protocol (IP) addresses, browser type, Internet Service Provider (ISP), date and time stamp, referring/exit pages, and possibly the number of clicks. These are not linked to any information that is personally identifiable.
6. Cookies and Web Beacons
Like any other website, SH Helper uses 'cookies'. These cookies are used to store information including visitors' preferences, and the pages on the website that the visitor accessed or visited. The information is used to optimize the users' experience by customizing our web page content based on visitors' browser type and/or other information.
Authentication Cookies:
When you sign in with Google, Google and Firebase may use essential cookies to keep you logged into your account across browsing sessions. These cookies are necessary for maintaining your authenticated session and enabling access to personalized features. They are automatically managed by the authentication providers and are deleted when you sign out or clear your browser cookies.
7. Google DoubleClick DART Cookie
Google is one of the third-party vendors on our site. It also uses cookies, known as DART cookies, to serve ads to our site visitors based upon their visit to our site and other sites on the internet. However, visitors may choose to decline the use of DART cookies by visiting the Google ad and content network Privacy Policy.
8. Advertising Partners
Some of the advertisers on our site may use cookies and web beacons. Our advertising partners include:
- Google AdSense
Each of our advertising partners has their own Privacy Policy for their policies on user data.
9. Third-Party Data Processors
We use Firebase (Google Cloud) as our third-party data processor for authentication, database services, and analytics. Firebase provides the infrastructure that enables our Google OAuth sign-in functionality and stores your user account data.
Firebase Services:
- Firebase Authentication - Handles the Google OAuth sign-in process and verifies your identity
- Cloud Firestore - Securely stores your user account information, tool history, and preferences

The privacy policy of Firebase applies to how they handle your data on their servers. We recommend reviewing Firebase's Privacy Policy for detailed information about their data handling practices.

12. Tool-Specific Privacy (Important)
Digital Ruler:
This tool may require access to your screen's PPI (Pixels Per Inch) data to provide accurate measurements. This data is processed locally and never uploaded.
70% Processing Rule:
As per our commitment, roughly 70% of our tools process data entirely within your browser (JavaScript). For the remaining tools that may require server-side processing in the future, we will ensure that data is encrypted and deleted immediately after the task is completed.
