Last updated: December 18, 2025

This Cookie Policy explains how Proposa("we", "us", and "our") uses cookies and similar technologies to recognize you when you visit our website at proposa.diaiti.com or use the Proposa browser extension. It explains what these technologies are and why we use them, as well as your rights to control our use of them.

1. What are cookies?

Cookies are small data files that are placed on your computer or mobile device when you visit a website. Cookies are widely used by website owners in order to make their websites work, or to work more efficiently, as well as to provide reporting information.

2. Google Analytics

We use Google Analytics, a web analytics service provided by Google LLC. Google Analytics uses cookies to help us analyze how users use the Site and enhance your experience.

2.1. What data is collected?

Google Analytics collects information such as:

  • How often users visit the site.
  • What pages they visit when they do so.
  • What other sites they used prior to coming to this site.

We use the information we get from Google Analytics only to improve this site and the Proposa product. Google Analytics collects only the IP address assigned to you on the date you visit this site, rather than your name or other identifying information.

2.2. Specific Cookies Used

The following cookies may be set by Google Analytics:

  • _ga: Used to distinguish users. (Expires in 2 years)
  • _gid: Used to distinguish users. (Expires in 24 hours)
  • _gat: Used to throttle request rate. (Expires in 1 minute)

3. Local Storage (Extension Data)

While not technically "cookies," the Proposa browser extension uses your browser's Local Storage (`chrome.storage.local`) to function efficiently.

  • API Keys: Your AI provider keys (OpenAI, Gemini, etc.) are stored locally on your device.
  • User Preferences: Your tone settings and profile information are stored locally.

This data never leaves your device and is not tracked by Google Analytics.

4. How can you control cookies?

You have the right to decide whether to accept or reject cookies. You can set or amend your web browser controls to accept or refuse cookies.

4.1. Browser Controls

Most browsers allow you to verify which cookies you have and delete them on an individual basis or block cookies from particular or all websites.

4.2. Google Analytics Opt-Out

You can prevent Google Analytics from using your information by downloading and installing the Google Analytics Opt-out Browser Add-on.

5. Updates to this Policy

We may update this Cookie Policy from time to time in order to reflect, for example, changes to the cookies we use or for other operational, legal, or regulatory reasons. Please therefore re-visit this Cookie Policy regularly to stay informed about our use of cookies and related technologies.
