Privacy Policy
This policy explains what Ningbo Tanji Technology Co., Ltd., the operator of floorplan.chat, collects, why, who else processes it, and the choices you have. Last updated 9 October 2026.
1. Who is responsible
floorplan.chat is operated by Ningbo Tanji Technology Co., Ltd. (“宁波探极科技有限公司”, “we”, “us”), which is responsible for the personal data described here. For any privacy question or request, contact contact@tangi.tech.
2. What we collect
Account. With email sign-up: your email address and a hash of your password (never the password itself). With Google or Apple: the account identifier they send, and the email, name, and profile image if they send those. We also record when you accepted the Terms of Service and this policy. Accounts created before that checkbox existed have no recorded acceptance time.
Projects. Your chat messages, project titles, reference images you upload, the floor-plan source and previews, rendered images you generate from a plan, and the history of edits made by you and by the agent.
Model execution logs. For each model turn, a private log of the prompt, the model’s output, token usage, diagnostics, and how the turn ended. API keys are removed from these logs.
Your own API key. If you save an OpenRouter key in Settings, it is stored encrypted and decrypted only for turns you choose to run on it.
Technical data. Our web server records requests, including IP address, time, the page or API requested, the referring page, and browser user agent.
3. Why we use it
- To provide the service you asked for: your account, your projects, and running the model turns you send (performance of our agreement with you).
- To keep the service secure, investigate failed or stopped runs, prevent abuse, and enforce the content rules in the Terms (our legitimate interests).
- To record that you accepted the Terms and this policy (our legitimate interests).
- To reply when you contact us (our legitimate interests, or your request).
- To meet legal obligations, such as responding to lawful requests.
We do not sell personal data, do not use it for advertising, and do not use your projects to train our own models.
5. International transfers
Our providers may process data in countries other than yours, including the United States. Where the law requires it, these transfers rely on appropriate safeguards such as standard contractual clauses.
6. How long we keep it
Account data is kept while your account exists. A project, with its messages and edit history, is kept until you delete it from the home page or your account is deleted. Model execution logs and server request logs are kept for operations and security, and are removed when no longer needed or when your account is deleted. Data may stay in backups for a limited time after deletion.
7. Your rights
Depending on where you live, you may have the right to access your data, correct it, delete it, restrict or object to how it is used, receive a copy in a portable format, and withdraw consent where we rely on it. You can delete projects yourself. For anything else, including deleting your account, email contact@tangi.tech. We may need to confirm it is you. You can also complain to your local data protection authority.
9. Security
Connections use HTTPS, passwords are hashed, saved API keys are encrypted, and execution logs are not served by the website. No system is perfectly secure; tell us at contact@tangi.tech if you find a problem.
10. Children
The service is not for anyone under 16, and we do not knowingly collect their data. If you think a child has given us data, contact contact@tangi.tech and we will delete it.
11. Changes
We will update this policy when what we collect or how we use it changes, and change the date at the top. If a change is significant, we will tell you on the site or by email.
