Your privacy is important to us. This Privacy Policy explains what information Notezio (“we”, “us” or “our”) collects when you visit notezio.com (the “Site”), how we use it and the choices you have.

By using the Site, you agree to the collection and use of information as described in this policy.

1. Information We Collect

Information you provide

We only collect personal information that you choose to give us. When you send a message through our Contact form, we receive your name, email address, subject and message. This form is processed with Google Apps Script and stored in a Google Sheet that only the site owner can access.

Information collected automatically

When you visit the Site, some information is collected automatically by us and by the third-party services listed below, such as:

• Browser type, device type and operating system
• Pages you visit, time spent on pages and the page that referred you
• Approximate location (country or city) based on your IP address
• Cookie identifiers and similar technologies

We do not use this information to identify you personally.

2. How We Use Information

We use the information we collect to:

• Reply to your questions, feedback and requests
• Understand how visitors use the Site so we can improve the content
• Display advertising that helps keep the Site free
• Keep the Site secure and working properly

We do not sell your personal information.

3. Cookies

Cookies are small text files stored on your device. The Site and our partners use cookies for analytics and advertising. You can block or delete cookies in your browser settings, but some features of the Site may not work as intended if you do.

4. Google Analytics

We use Google Analytics to understand how visitors use the Site. Google Analytics uses cookies to collect information such as the pages you visit and how long you stay. Learn more in How Google uses information from sites or apps that use its services. You can opt out by installing the Google Analytics Opt-out Browser Add-on.

5. Advertising and Google AdSense

We use Google AdSense to display ads on the Site.

• 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 visits to this Site and/or other sites on the Internet.
• You may opt out of personalized advertising by visiting Google Ads Settings.
• You can also opt out of some third-party vendors’ use of cookies for personalized advertising at www.aboutads.info/choices or, if you are in the EU or UK, at www.youronlinechoices.eu.

For more information, see Google’s Advertising Policies.

The Site checks in your browser whether ads were able to load and shows a message if an ad blocker is detected. This check runs only on your device and does not send or store any information.

6. Other Third-Party Services

The Site relies on the following services, which may receive your IP address and browser information when you load a page:

• GitHub Pages: hosts the Site and may keep server logs for security. See the GitHub Privacy Statement.
• Google Fonts: provides the fonts used on the Site. See the Google Privacy Policy.
• Ko-fi: provides the “Support” widget and handles donations and purchases of our PDF study notes. Payments are processed by Ko-fi and its payment providers; we never see or store your card details. See the Ko-fi Privacy Policy.
• Embedded content: some pages include images or media hosted by other websites (for example, GIFs from Giphy). These behave as if you visited the other website directly.

Each of these services has its own privacy policy, and we are not responsible for how they handle your information.

7. Links to Other Websites

The Site contains links to external websites, including official certification and documentation pages. We are not responsible for the content or privacy practices of those sites, and we encourage you to read their privacy policies.

8. Data Retention

We keep contact form messages only as long as needed to respond to you and for reasonable record keeping. You can ask us to delete your message at any time. Analytics and advertising data is retained by Google according to its own policies.

9. Your Rights

Depending on where you live (for example, under the GDPR in the EU/UK or the CCPA in California), you may have the right to:

• Access the personal information we hold about you
• Ask us to correct or delete it
• Object to or restrict how we use it
• Withdraw your consent at any time

To make a request, please contact us. You can also manage advertising and analytics cookies using the opt-out links above.

10. Children’s Privacy

The Site is not directed at children under the age of 13, and we do not knowingly collect personal information from them. If you believe a child has provided us with personal information, please contact us and we will delete it.

11. Data Security

We take reasonable steps to protect the information you share with us. However, no method of transmission over the Internet or electronic storage is completely secure, so we cannot guarantee absolute security.

12. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with a new “Last updated” date. Please review this page periodically.
