Privacy Policy

Last updated: January 2026

Introduction

Welcome to GLP-1 Timeline. We are committed to protecting your privacy and ensuring transparency about how we collect, use, and protect your information. This Privacy Policy explains our practices regarding data collection and usage when you use our website and calculator tool.

By using GLP-1 Timeline, you agree to the collection and use of information in accordance with this policy. We encourage you to read this Privacy Policy carefully to understand how we handle your data.

Data Collection

GLP-1 Timeline is designed with privacy in mind. The calculator operates entirely in your browser, and we do not store or transmit your personal health information to our servers in this MVP version. All calculations are performed locally on your device, which means your weight measurements, medication information, and other health-related data never leave your browser.

This client-side processing approach ensures that sensitive health information remains private and secure. You can use the calculator with confidence knowing that your personal health data is not being collected or stored by our servers.

What We Don't Collect

To be clear about what we don't collect, here's a comprehensive list of information we do not gather:

  • Your weight measurements or any body metrics
  • Your medication information, including type, dosage, or brand names
  • Personal health records or medical history
  • Identifying information such as your name, email address, or phone number (unless you explicitly provide it through contact forms)
  • Location data or IP addresses tied to your health information
  • Any data that could be used to identify you personally in connection with your health information

Our commitment to privacy means we've designed the calculator to function without requiring any personal health data to be sent to our servers. This approach protects your sensitive information while still providing you with useful insights about typical GLP-1 weight loss patterns.

Analytics and Usage Data

We may use standard web analytics tools to understand how visitors use our site, including page views, session duration, and general traffic patterns. This data is aggregated and anonymized, meaning it cannot be used to identify individual users. The analytics data helps us improve the website's functionality, understand user needs, and optimize the user experience.

The types of analytics data we may collect include:

  • Number of page views and unique visitors
  • Time spent on different pages
  • Browser type and device information (for compatibility purposes)
  • General geographic location (country or region level, not specific addresses)
  • Referring websites or search terms that led visitors to our site

This aggregated data does not include personal health information and cannot be linked back to individual users. We use this information solely to improve our services and understand how people interact with the GLP-1 Timeline calculator.

Cookies and Tracking Technologies

Our website may use cookies and similar tracking technologies to enhance your browsing experience and support our analytics efforts. Cookies are small text files stored on your device that help websites remember your preferences and improve functionality.

We may use cookies for the following purposes:

  • Remembering your unit preferences (pounds or kilograms) during your session
  • Analyzing website traffic and usage patterns
  • Supporting advertising services (see Advertising section below)

You can control cookie settings through your browser preferences. Most browsers allow you to refuse cookies or delete existing cookies. However, disabling cookies may affect some functionality of the website.

Advertising

We display Google Ads on our site to support the free availability of the GLP-1 Timeline calculator. Google may use cookies and similar technologies to serve ads based on your browsing activity and interests. These ads help us maintain the website without charging users for access to the calculator.

Google's advertising services may collect information about your visits to our site and other websites to provide you with relevant advertisements. This information is collected according to Google's Privacy Policy and advertising practices. We do not have direct access to the specific data Google collects for advertising purposes.

You can opt out of personalized advertising by visiting Google's Ad Settings page or by using browser extensions that block tracking cookies. Please refer to Google's Privacy Policy for detailed information about how they handle data collected for advertising purposes.

Third-Party Services

Our website may integrate with third-party services for analytics, advertising, and other functionality. These services have their own privacy policies and data collection practices. We encourage you to review the privacy policies of these third-party services to understand how they handle your information.

Some third-party services we may use include:

  • Google Analytics for website usage analysis
  • Google AdSense for advertising services
  • Vercel Analytics for performance monitoring

We select third-party services that we believe respect user privacy, but we are not responsible for their privacy practices. If you have concerns about how these services handle your data, you can adjust your browser settings or use privacy-focused browser extensions.

Data Security

While we don't store your personal health information, we take reasonable measures to protect any data we do collect. Our website uses industry-standard security practices, including HTTPS encryption for data transmission. However, no method of transmission over the internet or electronic storage is 100% secure, and we cannot guarantee absolute security.

Since the calculator operates entirely in your browser, the security of your health data during use depends primarily on your device's security. We recommend keeping your browser and operating system updated to ensure you have the latest security patches.

Children's Privacy

GLP-1 Timeline is not intended for use by children under the age of 18. We do not knowingly collect personal information from children. If you are a parent or guardian and believe your child has provided us with personal information, please contact us immediately, and we will take steps to remove that information from our systems.

Changes to This Policy

We may update this privacy policy from time to time to reflect changes in our practices, technology, or legal requirements. Any changes will be posted on this page with an updated revision date. We encourage you to review this Privacy Policy periodically to stay informed about how we protect your information.

If we make significant changes to this policy, we may provide additional notice through a prominent notice on our website or through other communication channels. Your continued use of the website after changes are posted constitutes acceptance of the updated Privacy Policy.
