Privacy Policy

1. Information we collect

• Account information: name, email address, profile image, and identifiers needed for authentication that are provided through Google sign-in
• Profile information: display name, language, default reply visibility, and attribution preferences
• Game information: replies, prompts, scores, AI comments, response timing, play history, Daily participation, likes, and achievements
• Anonymous-use information: a random visitor identifier used to associate signed-out play with the same browser
• Technical information: IP address, browser/device information, timestamps, server logs, and error information
• Analytics information: usage data collected through Google Analytics only when you allow analytics
• Contact information: the email address, subject, and message you submit through the contact form, plus a hashed IP value used to prevent abuse

2. How we use information

• Provide games, scoring, rankings, Daily, sharing, history, and account features
• Prevent abuse, enforce rate limits, secure the service, and investigate incidents
• Provide AI scoring, comments, sample replies, prompts, and image-related features
• Analyze and improve service quality, UI, game balance, and usage
• Respond to inquiries, rights requests, and legal obligations
• Prevent automated abuse and spam with Cloudflare Turnstile

3. Information that becomes public

Replies marked public may be displayed with their prompt, score, ranking information, and related game data. If you choose profile attribution, your display name may also be public.

Sharing features may create public share pages and social preview images. Other users may also share public replies using ReplyDojo sharing features.

4. AI processing

To provide scoring, comments, prompts, sample replies, and image-related features, ReplyDojo may send replies, prompts, images, and other necessary game context to AI processing providers such as Cloudflare Workers AI. We limit this processing to what is reasonably necessary for those features.

Do not enter passwords, government identifiers, payment information, confidential business information, or other sensitive data into reply fields.

5. Google sign-in and Google Analytics

ReplyDojo uses Google authentication for sign-in. Google's own terms and privacy policy apply to Google's handling of authentication data.

Google Analytics is loaded only after you choose “Accept analytics” in the cookie settings. If you choose “Essential only,” Google Analytics is not loaded. You can change this choice at any time from “Cookie settings” in the footer.

6. Cookies and local storage

We use essential cookies for signed-in sessions, anonymous-play ownership, rate limiting, and related security functions. Your cookie preference is stored in browser local storage. See the Cookie Policy for details.

7. Retention and deletion

We retain information for as long as reasonably necessary to provide the service, protect security, address abuse or disputes, maintain backups, and meet legal obligations. When you delete a reply, it is removed from public ReplyDojo surfaces, but database records may be retained for audit, anti-abuse, integrity, backup, or legal purposes.

8. Service providers and international processing

We may use external providers for authentication, analytics, AI processing, infrastructure, content delivery, and abuse prevention. The contact form uses Cloudflare Turnstile, which sends technical information needed for bot detection to Cloudflare. To notify the operator of an inquiry, the submitted email address, subject, and message may also be sent through the mail server provider used by the operator. These providers may process information in countries outside Japan.

9. Security

We use reasonable measures such as access controls, authentication, protected communications, and backups. No internet transmission or storage system can be guaranteed to be completely secure.

10. Your choices and requests

You can use available product controls to change the default visibility or attribution applied to future replies and to delete replies. Requests for access, correction, deletion, or other rights required by applicable law will be handled within a reasonable scope after appropriate identity verification.

11. Changes to this Policy

We may update this Policy as the service or applicable requirements change. We will provide reasonable notice within the service when a change is material.
