Privacy Policy

FangJianJian respects the privacy of floor plans, personal information, and report data. This Policy explains what may be collected, how it is used and protected, and how users can request access, correction, or deletion.

1. Data controller

• Brand: 房检检（FangJianJian）

• Website: https://fangjianjian.app

• Support and data requests: support@fangjianjian.app

Payment providers, messaging platforms, and other services may independently control data they collect.

2. Information we may collect

2.1 Account and contact data

Name or nickname, email, phone number, login credentials, language, and country or region.

2.2 Floor-plan and case data

Uploaded floor plans, home orientation, outline, 24-Mountains or other directional markings, room names and functions, doors, bedrooms, kitchen and other user markings, resident-to-room relationships, notes, and supplemental explanations.

Floor plans can reveal private household structure. Remove house numbers, identity numbers, phone numbers, and unrelated information before upload.

2.3 Resident data

Depending on the product: gender, date or year of birth, family relationship, rooms actually used, and voluntarily supplied living information. Do not submit medical records, identity documents, banking data, or unrelated sensitive information unless expressly required.

2.4 Reports and generated content

Rule-analysis results, automatically generated reports, report versions, feedback, and regeneration or revision records.

2.5 Order and payment data

Order ID, product, price, currency, payment/refund state, processor transaction identifiers, billing email, and region. Complete card numbers, security codes, and payment passwords are normally handled directly by the payment provider and are not generally stored by FangJianJian.

2.6 Device and technical data

IP address, browser and device, operating system, page visits, login and action times, error logs, security and anti-fraud records, cookies, and similar technologies.

2.7 Communications

When users contact us by email, Zalo, Messenger, WhatsApp, or another channel, we may keep the account, message, order/case ID, attachments supplied by the user, and support records.

3. How information is used

Information may be used to create and manage accounts; receive, store, and process floor plans; generate, display, and download reports; confirm payment and delivery; handle refunds, complaints, and disputes; provide support; diagnose errors; prevent fraud and unauthorized access; improve the workflow and user experience; meet legal, tax, accounting, and regulatory obligations; and send marketing only with required consent.

Detailed floor plans are not sold to advertisers merely because a person uses the service.

4. Automated analysis and AI

FangJianJian is independently developed and uses third-party AI technology in parts of its floor-plan interpretation, analysis, and report-writing workflow. These services may include models provided by OpenAI. FangJianJian is not affiliated with, endorsed by, sponsored by, or officially associated with OpenAI.

To perform the requested floor-plan analysis and generate the text-based report, the uploaded floor-plan image, home orientation, room labels and functions, resident-to-room relationships, customer questions or notes, structured facts, rule results, and necessary text may be sent to contracted AI-model, cloud, or server providers. FangJianJian minimizes the data sent to what the requested function reasonably requires.

Without separate notice and required consent, complete floor plans are not used for public display, advertising, sale, or a publicly accessible dataset. Automated results may contain omissions or errors, which users can report to support.

Third-party providers process relevant data under their applicable service terms, privacy policies, and data-processing commitments. FangJianJian selects, configures, and limits contracted providers according to service needs and reasonable data-protection requirements.

The delivered product is a primarily text-based downloadable PDF report. It may reproduce the customer’s original floor plan or include functional annotations, but it does not generate new images or videos from user prompts.

5. Legal bases

Depending on applicable law, processing may rely on consent, performance of a digital product or service, requested pre-purchase steps, legal obligations, security and dispute handling, or legitimate business and technical interests that do not improperly override fundamental rights. Consent may be withdrawn without affecting earlier lawful processing.

6. Recipients

Necessary information may be shared with cloud and storage providers, AI/model providers, payment processors or a Merchant of Record, email and support providers, security and anti-fraud vendors, analytics providers, professional advisers, competent authorities, and lawful successors in a reorganization. Contracted providers should be restricted to agreed purposes and reasonable safeguards.

7. International transfers

Servers, cloud, model, and payment providers may be outside the user’s region. Where required, FangJianJian will limit data, assess providers, use reasonable contractual protections, apply access controls and encryption, and meet applicable data-protection duties.

8. Retention

Data is kept only as needed: account data for the account and reasonable dispute period; floor plans, markings, and reports while a case is retained or until deletion is requested; support records while needed for support or disputes; security logs for a limited period; payment records as required by tax, accounting, consumer, and payment rules; and backups until overwritten in the normal cycle.

When no purpose or legal, payment, or dispute hold remains, data will be deleted, anonymized, or no longer used.

9. Security

Reasonable measures include HTTPS, authentication, access controls, file isolation, logging and monitoring, backups, provider restrictions, and masking where needed. No network system is absolutely secure. Users must protect credentials and verification codes. Legally notifiable incidents will be investigated, addressed, and notified as required.

10. User rights

Depending on law, users may have rights to information, consent or refusal, withdrawal, access, correction, deletion or anonymization, restriction, objection, a copy, complaint, and legal remedy.

Submit requests to support@fangjianjian.app. Reasonable account, email, order, or case verification may be required. Never email complete card passwords, security codes, or verification codes. Some records may be retained for tax, payment, anti-fraud, dispute, or legal duties; the reason will be explained.

11. Cookies and similar technologies

The site may use strictly necessary authentication cookies and functional language or settings storage. Marketing cookies and other non-essential tracking technologies are used only with consent where required by applicable law.

The site uses cookieless, first-party anonymous operational measurement to understand where users leave a page or service step. It is limited to page paths without query parameters, server receipt time, time on page, and a random session identifier created for one page-open visit and never retained across visits. Operational measurement does not store visitor network addresses, browser information, referrers, device fingerprints, or long-term visitor identifiers, and is not combined with customer, order, or third-party data. The internal dashboard shows only page- and time-level aggregates; anonymous raw events are retained for no more than 90 days. No third-party marketing tracker is currently configured.

12. Third-party messaging

Zalo, Messenger, and WhatsApp apply their own privacy policies. Do not send card passwords, verification codes, or unrelated identity documents through ordinary chat.

13. Children

FangJianJian does not intentionally collect children’s data or sell reports to minors. A parent or guardian may contact support regarding unauthorized submission.

14. Updates

This Policy may change with functions, providers, or law. The current version and date will appear here, and material changes may be notified through the site, email, or another reasonable method.
