This Privacy Policy describes how your personal information is collected, used, and shared when you visit or use services from https://guiren.app (the "Site").

Personal Information We Collect

When you visit the Site, we automatically collect certain information about your device, including information about your web browser, IP address, time zone, and some of the cookies that are installed on your device. Additionally, as you browse the Site, we collect information about the individual web pages that you view, what websites or search terms referred you to the Site, and information about how you interact with the Site. We refer to this automatically-collected information as "Device Information."

We collect Device Information using the following technologies:

• "Cookies" are data files that are placed on your device or computer and often include an anonymous unique identifier. For more information about cookies, and how to disable cookies, visit http://www.allaboutcookies.org.
• "Log files" track actions occurring on the Site, and collect data including your IP address, browser type, Internet service provider, referring/exit pages, and date/time stamps.
• "Web beacons," "tags," and "pixels" are electronic files used to record information about how you browse the Site.

Additionally when you create an account, use our services or participate in the Site, we collect certain information from you, including your name, phone number, email address, and birth information for astrological calculations. We refer to this information as "User Information."

When we talk about "Personal Information" in this Privacy Policy, we are talking both about Device Information and User Information.

How Do We Use Your Personal Information?

We use the User Information that we collect generally to provide services through our website including arranging, calculating and storing your astrological information, maintaining your user profile, and communicating with you.

We use the Device Information that we collect to help us screen for potential risk and fraud, and more generally to improve and optimize our Site (for example, by generating analytics about how our customers browse and interact with the Site, and to assess the success of our marketing and advertising campaigns).

Sharing Your Personal Information

We share your Personal Information with third parties to help us use your Personal Information, as described above. We use Google Analytics to help us understand how our users use the Site. You can read more about how Google uses your Personal Information here: https://www.google.com/intl/en/policies/privacy/. You can also opt-out of Google Analytics here: https://tools.google.com/dlpage/gaoptout.

Finally, we may also share your Personal Information to comply with applicable laws and regulations, to respond to a subpoena, search warrant or other lawful request for information we receive, or to otherwise protect our rights.

AI Conversations and Memory

When you chat with the AI assistant, your messages and the chart or hexagram data you discuss are sent to a third-party AI provider (for example OpenAI, Groq or Google) to generate a reply. Conversations you delete are removed from your list but may be retained by us.

"AI memory" is optional and off by default. If you turn it on, the notes you write on the "AI记忆" page (and your style preferences) are included with your chats and are therefore also sent to the AI provider. You can switch memory off for any single conversation, and edit, disable or delete any note, or all of them, at any time. Deleting a memory note removes it permanently (it cannot recall text already sent to the provider), and all memory notes and preferences are deleted when you delete your account.

"Learning from my chats" is a second, separate option that is also off by default and can only be switched on while AI memory is on. If you turn it on, after a conversation has been quiet for about 30 minutes, the messages you sent in it after you turned the option on (in full, including anything such a message contains) are sent to a third-party AI provider, which proposes short notes about lasting preferences or circumstances you mentioned about yourself. Notes written this way are labelled "AI 学到" on the "AI记忆" page, and you can edit, disable or delete them like any other note; a conversation with memory switched off is never read, and when you delete a conversation you can choose to delete the notes learned from it as well. To avoid learning a deleted note again we keep a one-way fingerprint of its wording (not the wording itself) until you delete your account. We aim to exclude chart contents, other people's details, health, financial, legal and contact information, but the process is automated, so please review your notes.

Data Retention

When you create an account through the Site, we will maintain your User Information for our records unless and until you ask us to delete this information.

Changes

We may update this privacy policy from time to time in order to reflect, for example, changes to our practices or for other operational, legal or regulatory reasons.
