Privacy Policy

ChessFog (“the App”) — Last updated: 6 April 2026

This Privacy Policy describes how we handle information when you use the ChessFog mobile application and related online services. By using the App, you agree to this policy. If you do not agree, please do not use the App.

1. Who we are

The App is provided by Netnumerics Ltd (“we”, “us”). For privacy questions, contact: ma@netnumerics.com

2. What the App does

ChessFog is an online chess game. The App connects to our servers over the internet to provide accounts, gameplay, matchmaking, and related features. The Android version may offer purchases or subscriptions through Google Play.

3. Information we collect

Depending on how you use the App, we may process:

• Account data: such as username and authentication-related data you provide when you sign in or register.
• Gameplay data: moves, game state, invitations, and similar data needed to operate chess games.
• Support communications: messages you send when contacting support, if that feature is available.
• Subscription status: information required to verify entitlements for premium features, in coordination with Google Play where applicable.
• Technical data: data our servers receive in the normal course of operating a networked app (for example timestamps, identifiers needed for sessions, and diagnostic information as described in our server configuration).

We do not use the App to read your contacts, photos, or precise device location. The App requests network access to communicate with our services and uses Google Play Billing where purchases are offered.

4. How we use information

We use the information above to:

• Provide, maintain, and improve the App and our services;
• Authenticate you and prevent abuse;
• Process gameplay and social features you choose to use;
• Handle subscriptions and entitlements where applicable;
• Respond to support requests and comply with legal obligations.

5. Legal bases (EEA/UK users)

If applicable law requires a “legal basis”, we rely on performance of a contract (providing the service you requested), our legitimate interests (security, fraud prevention, product improvement), and, where required, your consent.

6. Sharing of information

We may share data with:

• Service providers who host or operate our infrastructure (for example cloud or hosting providers) under appropriate agreements.
• Google when you use Google Play Billing: purchase handling is subject to Google’s terms and policies.
• Authorities when required by law or to protect rights and safety.

We do not sell your personal information in the conventional sense of “selling” data to data brokers for their marketing lists.

7. Retention

We keep information only as long as needed for the purposes above, including legal, accounting, and security requirements, unless a longer period is required by law.

8. Security

We use reasonable technical and organizational measures to protect information. No method of transmission over the internet is 100% secure.

9. Children

The App is not directed at children under the age required by your region for consent without parental approval. If you believe we have collected such information in error, contact us and we will take appropriate steps.

10. Your rights

Depending on where you live, you may have rights to access, correct, delete, or restrict processing of your personal data, or to object to certain processing. Contact us at the email above. You may also lodge a complaint with your local data protection authority.

11. International transfers

Our servers or providers may be located outside your country. Where required, we use appropriate safeguards for cross-border transfers.

12. Changes

We may update this policy from time to time. We will post the new version here and update the “Last updated” date. Continued use of the App after changes means you accept the revised policy.

13. Disclaimer

This document is provided as a practical template. It is not legal advice. Have it reviewed by a qualified lawyer for your jurisdiction and your exact data practices before publishing.
