Privacy Policy

Content data includes things like the pages you visit, the questions you ask, and the answers you receive in Chat. When you share your content data with us, it helps us improve the speed and accuracy of our models. We really appreciate it, and take extra steps to maintain your privacy throughout the process.

When your content data leaves your device, it is no longer tied to your profile. Your content data then lives on your device 

 on our servers for 30 days while we use it to improve Dia. When we process it on our servers, we can only see the data itself, not who sent it.

The data is deleted from our servers after 30 days. We can’t remove it sooner, even if you request, because it’s no longer associated with you.

Dia will also work to avoid storing and processing data from sensitive sites (like banks or healthcare).

As you use Dia, you remain in control. You can stop sharing content data at any time in the Privacy panel in Settings.

Questions? Don’t hesitate to reach out at 

We believe you should be able to go just about anywhere online without giving up your privacy. But to get helpful answers with Dia, you sometimes need to share a little — like your question or the page you’re on.

Here’s how the Dia browser works: your user data is encrypted and stored locally, right on your device. When you Chat with Dia, your request is either routed to a search engine or a trusted AI partner. If it’s AI, the data required for your request (like your question, or your open tab) is briefly sent to our servers and passed to a trusted partner, with an answer returned in seconds.

Our goal is to keep your data safe while keeping you moving.

#fff

Chats, history, bookmarks, browsing context, and files are encrypted and stored locally. When you ask Dia’s Chat a question, only the data relevant to that request is sent off your device. Browsing context allows you to ask Dia about your last 7 days of activity. This is powered by summaries, created on our servers and stored locally on your device. Browsing context can be disabled in Settings at any time.

Your data lives on your device.

When your request is routed to our servers, we only send the necessary data (your question, the page you’re on, etc.) to our partners. They are under contract not to store or train their models on your data once your request is complete. Dia will also work to avoid storing and processing data from sensitive sites (like banks or healthcare).

Your data is only shared when needed.

When you clear your chats, files, or history, they’re gone for good. And when you browse in incognito mode, nothing is ever stored. If you choose to share your content data with Dia, it’s not tied to your profile and is deleted after 30 days. (Learn more about content data below.)

You can delete your data at any time.

We will never sell your personal data. Period. We only use it only to help Dia provide the most accurate and helpful results.

Your data is not for sale.

Dia is built to protect your data. These four principles guide everything we do:
