Fogboard ("the App", "we", "us", or "our") is a daily blindfold chess puzzle application. We respect your privacy and are committed to protecting it.
This Privacy Policy explains what information we collect (if any), how we use it, and your rights. By using Fogboard, you agree to the practices described in this policy.
Summary
Fogboard is designed with privacy in mind:
No user accounts or sign-in required
No personal information collected
No advertising
No tracking across apps or websites
Game progress and streaks are stored only on your device
Information We Collect
Information We Do Not Collect
We do not collect, store, or transmit:
Name, email address, or any contact information
Location data
Device advertising identifiers (IDFA / AAID)
Contacts, photos, or media
Browsing or search history
Payment information (the App currently has no in-app purchases)
Any data that can identify you personally
Local Data Stored on Your Device Only
The App stores the following information locally on your device using standard device storage:
Daily puzzle progress and results
Current streak and attempt history
Vision card usage and scores for the current day
App settings (sound, notifications preference, etc.)
This data never leaves your device and is not accessible to us. Uninstalling the App permanently deletes this local data.
Limited Technical Data (if any)
If the App needs to fetch the daily puzzle from our servers:
A temporary, anonymous request may be made to retrieve the puzzle of the day
We may receive standard server logs (IP address, device type, timestamp) that are automatically generated by hosting providers
These logs are used only for security, reliability, and to serve the correct daily puzzle
We do not use this information to identify or profile individual users
Logs are retained only for a short period and then deleted
We do not use this data for advertising, analytics profiling, or any commercial purpose beyond operating the App.
How We Use Information
Any limited technical data mentioned above is used solely to:
Deliver the correct daily puzzle to your device
Ensure the App functions reliably and securely
Protect against abuse or technical issues
We do not sell, rent, or share your information with third parties for marketing or advertising purposes.
Third-Party Services
Fogboard does not use:
Advertising networks
Third-party analytics SDKs (such as Firebase Analytics, Mixpanel, etc.)
Crash reporting tools that collect personal data
Social login or authentication services
Any tracking or cross-app identification technologies
The App may rely on Apple App Store or Google Play infrastructure for distribution and updates. Those platforms have their own privacy policies.
Children's Privacy
Fogboard is suitable for users of all ages and has a 4+ age rating.
We do not knowingly collect any personal information from children under 13 (or the equivalent age in your jurisdiction). Because the App collects no personal data, there is no special risk related to children's privacy.
Data Security
Since nearly all data remains on your device, the primary security of your information depends on the security of your own device.
For any server-side requests related to the daily puzzle, we use standard industry practices (HTTPS, etc.) to protect data in transit.
Data Retention and Deletion
Local game data stays on your device until you clear the App data or uninstall Fogboard.
Any temporary server logs are automatically deleted after a short retention period.
Because we do not maintain user accounts or personal profiles, there is no account data to delete on our side.
If you have contacted us by email and wish your correspondence to be deleted, simply reply to the email or contact us using the details below.
Your Rights
Depending on where you live, you may have rights under applicable data protection laws (including GDPR, CCPA/CPRA, and others). These may include the right to:
Access information we hold about you
Request deletion of information
Object to certain processing
Because Fogboard collects virtually no personal data, most of these rights will not apply in practice. If you have any request, please contact us and we will respond promptly.
International Users
Fogboard is operated from India. If you access the App from outside India, any limited technical data may be processed in India or in the locations of our hosting providers. By using the App you acknowledge this.
Changes to This Privacy Policy
We may update this Privacy Policy from time to time. The "Last updated" date at the top will reflect the most recent version. Continued use of the App after changes constitutes acceptance of the updated policy.
We encourage you to review this page periodically.
