Caicaimiyu (猜猜謎語) Privacy Policy
Effective date: 2026-11-01
"Caicaimiyu (猜猜謎語)" (the "Service") values users' privacy. This policy explains how we collect, use and retain personal data. Please read it carefully.
1. Personal Data We Collect
| Category | When collected | Details |
|---|---|---|
| LINE account data | When the user logs in with LINE | LINE user ID (cannot be traced back to a real name), display name, profile picture URL |
| Guest identifier | When using guest mode | A randomly generated guest ID (contains no information that can identify you) |
| Game records | Each time you play | The words guessed in each round, ranks, time taken and number of hints used. Raw per-guess records are kept for 3 months and then deleted automatically; however, the aggregated data needed for leaderboards and personal statistics (total attempts, best rank, hints used and so on) continues to be kept in the account record |
| Token transaction records | When tokens are granted or used | Transaction type, amount, time |
| Network address (IP) | On every connection | Used to detect abuse (for example, a large number of guest accounts created from one source in a short time); the source IP is obtained after traffic is forwarded through the Cloudflare edge network |
| Cookies | When using the Service | Essential cookies used to keep you logged in (refresh token); see "6. Use of Cookies" |
The Service does not actively collect sensitive personal data such as real names, national ID numbers or credit card numbers. If paid token purchases are opened in the future (not yet available; see below), payment information will be handled directly by a third-party payment provider (ECPay (綠界科技) is planned). The Service only receives the transaction result and does not handle or store payment details such as card numbers.
2. Purposes of Collection
- To provide the game, keep you logged in, and calculate leaderboards and friend-battle results.
- To prevent improper use (such as automated programs, or creating duplicate accounts to evade limits).
- To troubleshoot service problems and perform statistical analysis for quality improvement (such as tuning the quality of the semantic word data).
- If paid features are opened in the future, to process token transactions and disclose the legally required issuer information.
3. Retention Periods
| Data | Retention period |
|---|---|
| Per-guess records (raw data) | 3 months, then deleted automatically by the system |
| Aggregated account statistics (ranks, token balance, etc.) | For as long as the account exists |
| LINE login link data | For as long as the account exists; removed when the user requests account deletion |
| Guest data | Kept on the device; clearing browser data is equivalent to deleting it |
4. Data Processing and International Transfers
The Service's servers and database are hosted on Render (Singapore data center), and front-end content is delivered through Cloudflare's global edge network. As a result, users' personal data is transferred to, and processed and stored in, regions outside Taiwan (Singapore and the locations of Cloudflare nodes) [Legal confirmation pending: whether the special cross-border transfer procedures under Article 21 of the Personal Data Protection Act must be followed].
5. Disclosure to Third Parties
- LINE: when a user logs in with LINE, the Service obtains the user ID, display name and profile picture in accordance with LINE platform rules. The collection of that data is governed by LINE's own privacy policy.
- Payment provider: once paid features are opened, token transactions will be processed with ECPay (綠界科技); its scope of data processing will be announced separately at that time.
- Except in the cases above or as otherwise required by law, the Service does not provide users' personal data to any other third party.
6. Use of Cookies
The Service uses essential cookies to keep you logged in (a refresh token, which automatically renews an access credential that is valid for 15 minutes). These cookies are required for the Service to operate and cannot be turned off individually. The Service does not use third-party advertising tracking cookies.
7. Your Rights
Under the Personal Data Protection Act, you may request that the Company:
- Let you inquire about or review your personal data.
- Provide you with a copy.
- Supplement or correct it.
- Stop collecting, processing or using it.
- Delete it (a guest account can be removed simply by clearing browser data; a LINE-login account can be deleted by yourself by choosing "Delete account" in the account menu at the top right of the site, or by applying through the contact details below).
8. Minors
The Service is rated "General Audience" (普遍級), but children under seven are advised to use it together with a parent or guardian. The Service does not knowingly collect personal data from children beyond what the game requires.
9. Changes to This Policy
If this policy is revised, the revised content and its effective date will be announced on the Service's pages.
