Privacy Policy
Effective Date: July 1, 2026
Welcome to Daikokuten (the "App"), a rewards-based gaming platform operated under the domain
dktprotocol.com ("we," "our," or "us"). We are committed to protecting your privacy. This
Privacy Policy explains how we collect, use, disclose, and safeguard your information when
you use our mobile application.
By downloading and using Daikokuten, you agree to the collection and use of information in
accordance with this policy. If you do not agree with the terms of this Privacy Policy,
please do not access the App.
1. Information We Collect
We collect several types of information to provide, secure, and improve your gaming experience:
A. Information You Provide Directly
- Account Credentials: When you create an account, we collect your email address and username. We also collect and store your password, which is securely encrypted using a strong cryptographic hash (bcrypt).
- Google Sign-In Data: If you choose to register or log in using your Google Account, we receive your Google email address, name, and profile picture directly from Google.
B. Information Collected Automatically
- In-App Activity Data: We track your gameplay history (such as Blackjack games played), virtual points earned, and internal transaction logs. Please note that these virtual points are strictly for entertainment and have no real-world monetary value.
- Device and Security Data: We automatically log your device's IP address to help prevent fraud, multi-account abuse, and malicious activity.
- Ad Interaction Data: Our advertising partner, Google AdMob, automatically collects data regarding the ads you view and interact with inside the App to measure ad performance and prevent ad fraud.
2. How We Use Your Information
We use the data we collect for the following specific purposes:
- Account Management & Authentication: To set up your account, verify your identity, and allow you to log in securely.
- Game Features & Rewards Tracking: To run the Blackjack games, maintain your virtual point balance, and log your in-app rewards activity.
- Advertising & Personalization: To serve advertisements through Google AdMob, which may include personalized ads based on your preferences (where permitted).
- Fraud & Abuse Prevention: To monitor for cheating, bot activity, unauthorized access, and any behavior that violates our terms.
- Internal Analytics: To review aggregated, non-personal data to understand how users interact with the App so we can improve gameplay and performance.
3. Third-Party Services
We partner with third-party services to handle specific features like authentication,
monetization, and communication. These third parties have access to your information only to
perform these tasks on our behalf:
- Google Sign-In: Used for streamlined user authentication. Your data is handled according to the Google Privacy Policy.
- Google AdMob: Used to deliver in-app advertisements. AdMob may use device identifiers to personalize ads. You can manage your ad preferences through your mobile device settings.
- SMTP Email Service: We utilize an external email delivery service to send essential account emails, such as registration verification codes and password resets.
4. Data Retention
We only store your information for as long as necessary to fulfill the purposes outlined in this policy:
- Account Data: Your profile information (email, username, hashed password) is retained for the lifespan of your account. It will be kept until you explicitly request its deletion.
- Transaction Logs: Records of your in-game activities and point distributions are kept for 12 months before being permanently deleted or anonymized.
- Ad Logs: Data related to ad interactions and views is retained for 6 months for tracking and validation purposes.
5. Data Security
The security of your data is a top priority. We implement industry-standard administrative
and technical security measures:
- Passwords are never stored in plain text; they are protected using secure bcrypt hashing.
- Data transmission between the App and our servers is secured using encrypted protocols.
- While we strive to use commercially acceptable means to protect your personal information, no method of transmission over the internet or electronic storage is 100% secure, and we cannot guarantee absolute security.
6. Children's Privacy
Daikokuten is not intended for use by children under the age of 13. We do not knowingly
collect personal information from children under 13. If we discover that a child under 13 has
provided us with personal information, we will immediately delete this data from our servers.
If you are a parent or guardian and are aware that your child has provided us with personal
data, please contact us.
7. Your Rights and Choices
You control your data. Depending on your location, you have the following rights regarding
your personal information:
- Access and Export: You have the right to request a copy of the personal data we hold about you.
- Correction or Deletion: You can request that we update incorrect data or permanently delete your account and all associated personal information.
- Opt-Out of Personalized Ads: You can opt out of targeted advertising by adjusting the privacy and ad tracking settings on your iOS or Android device (e.g., enabling "Limit Ad Tracking" or resetting your advertising ID).
