Privacy Policy

• Things you enter into the calculators: equipment levels, ore configuration, upgrade plans, and similar inputs. By default this stays in your browser and never leaves your device. If you sign in, it is also saved to our database so it can sync across your devices.
• Account information: sign-in is optional and provided through Google. If you sign in, Google shares your name, email address, and profile picture with us. We use this only to identify your account and sync your data. We never see or store your Google password.
• Clash of Clans game data: if you enter a player or clan tag to import your profile, we send that tag to Supercell’s official Clash of Clans API (through our own server) to fetch public game data such as your equipment levels and clan war record. We do not receive your Supercell login or any private account details.
• Usage and analytics: we use Google Analytics and Cloudflare analytics to understand how the site is used (pages visited, rough location, device and browser type). This information is aggregated and is not used to personally identify you.

• To provide and operate the calculators.
• To sync your saved data across devices when you are signed in.
• To understand usage and improve the site.

We do not sell your data, and we do not use it for advertising.

We rely on a small number of service providers, each with its own privacy policy:

• Supabase: database and authentication. Stores your account and synced data.
• Google: sign-in and analytics.
• Cloudflare: analytics and content delivery.
• Vercel: website hosting.
• Supercell Clash of Clans API: public game data, only when you import a profile.

We use your browser’s local storage to keep your calculator data and, if you are signed in, your login session. Analytics providers may set cookies. You can clear local storage and cookies at any time through your browser. Doing so removes locally saved data and signs you out.

• Data saved only in your browser stays until you clear it.
• If you are signed in, your synced data is kept until you delete it or ask us to.

To delete your account and synced data, contact us at support@clashcalculator.com.

We use established providers and standard access controls. No method of storage or transmission is completely secure, but the data we hold is limited to game-planning information and basic account details.

This site is not directed to children under 13, and we do not knowingly collect data from them.

We may update this policy from time to time. The date at the top reflects the latest version.
