1. Information We Collect
Student Utility Hub is designed to collect as little data as possible. Specifically:
1.1 Data Stored Locally (Your Device Only)
We use localStorage in your browser to store:
- Your theme preference (light or dark mode)
- Recent calculation history (last 5 per tool)
This data exists only on your device and is never transmitted to us.
1.2 Contact Form
When you submit our contact form, we collect your name, email, and message to respond to your query. This data is transmitted via Cloudflare Workers and stored only long enough to reply.
2. Cookies
We use minimal, essential cookies only:
- Session cookies: Standard browser session cookies.
- Analytics: We may use privacy-respecting analytics (Cloudflare Analytics) that do not identify individual users.
Except for Google AdSense cookies used to serve ads (see Section 4 below), we do not use other third-party tracking or advertising cookies.
3. Uploaded Files (PDF Tools)
PDF files you upload to our tools are processed entirely in your browser using client-side JavaScript (pdf-lib). Files are:
- Never uploaded to any server
- Never stored or cached by us
- Processed only in your browser memory
4. Advertising & Third-Party Cookies (Google AdSense)
We use third-party advertising companies to serve ads when you visit our website. Specifically, we use Google AdSense:
- Third party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.
- You may opt out of personalized advertising by visiting Ads Settings. (Alternatively, you can opt out of a third-party vendor's use of cookies for personalized advertising by visiting www.aboutads.info).
5. Your Rights
Since we collect minimal personal data, your rights are simple:
- Delete local data: Clear your browser's localStorage at any time.
- Contact form data: Email us to request deletion of any contact data.
- Opt out of analytics: Use a browser ad blocker or Cloudflare's privacy settings.
