We take your privacy seriously. This policy explains how ZhiGui handles your personal information. Please read it carefully before using the Service; by using the Service you are deemed to have agreed to the handling described here.
1. Information we collect
1.1 Information you provide
- Account information: the username, display name and linked phone number that we generate or that you change, together with any password you set (stored only as a salted hash — we cannot recover your plaintext password). Your phone number is used to create the account, sign in with a verification code, reset your password, confirm a number change and for essential account-security communication.
- Your content: what you enter in notes, conversations, schedules, goals, decisions and reminders, plus any attachments you upload (PDF, DOCX, XLSX, images, text and so on).
- Preferences: interface theme, language and usage preferences.
1.2 Information collected automatically
- Usage data: sign-in times, which features you use, token consumption (for billing and quotas), and subscription and payment status.
- Device and logs: basic logs such as IP address, browser type and device identifiers (for security and troubleshooting).
2. How we use information
- To provide, maintain and improve the Service (including the core features: AI conversation, knowledge organisation and schedule reminders);
- To calculate and verify plan allowances, token consumption and billing;
- Security protection (preventing abuse and attacks, protecting accounts);
- Customer support and contacting you (when you reach out to us);
- Complying with legal and regulatory requirements.
We do not sell, rent out or use your personal information for targeted advertising.
3. Sharing with third parties
To deliver specific features we may share the necessary information with the following third parties:
| Scenario | Third party | What is shared |
|---|
| AI conversation / document summary / image recognition | DeepSeek | Conversation content, extractable attachment text, and image data you actively attach in that turn (to generate the AI reply and summary) |
| Online payment | Alipay | Order number and amount (to create the payment order and confirm the result) |
| Verification-code sign-in / password reset | Tencent Cloud SMS | Phone number and verification-code template parameters (only to send and verify the code) |
| Speech recognition (if used) | Built-in browser service | Audio is processed locally in your browser and is not uploaded to our servers |
Before sending content to the AI provider we cap the total size of very long documents and images. Please do not submit highly sensitive information such as ID or bank card numbers in conversations or attachments, to keep your risk low.
4. Storage and security
- Your data is stored on cloud servers we rent (mainland China) and protected by access controls, encryption in transit (HTTPS) and similar measures.
- Passwords are stored only as salted hashes; payments are completed through the Alipay channel, and we do not store your full payment credentials.
- We do our best to protect your data, but no transmission over the internet is absolutely secure. Please also keep your account credentials safe.
5. Retention and deletion
- Your account and data are retained until you close the account.
- After you close your account we will delete or anonymise your content and account data within 30 days (except where the law requires retention — payment records, for example, are normally kept for at least 3 years for tax and audit purposes).
- You can export or delete your notes, attachments and other content at any time (the panel provides a delete entry point).
6. Cookies and local storage
We use an HttpOnly session cookie solely to keep you signed in; page scripts cannot read it. Interface theme and layout preferences may be kept in local storage. We do not use third-party tracking cookies.
7. Protection of minors
The Service is intended for adults. If you are under 14, please do not register for or use the Service. If you are 14 or older but under 18, please use it with the consent and supervision of a guardian.
8. Your rights
Under applicable law you have the right to: access and copy your personal information, correct inaccurate information, delete information, close your account, withdraw consent (withdrawal does not affect processing already carried out beforehand), and obtain a copy of your data. To exercise any of these rights, contact us through the channel below.
9. Changes to this policy
This policy may be updated as our business develops. Material changes will be flagged through a site notice or a prominent placement. Continuing to use the Service after an update means you accept it.
10. Contact us
If you have any question, comment or complaint about this policy, please contact us through the feedback form. Every message is read by a person.
