Privacy Policy for Calculón

Last updated: August 20, 2026

Calculón is a mental math game designed for children. We take privacy very seriously, especially when it comes to minors. This page explains, in plain language, what data we use and what we don't.

What we do NOT collect or store

• We don't ask for your real name, last name, age, address, phone number, or email.
• There are no accounts or passwords. No personal information is needed to play.
• We don't use personalized advertising or tools that build a profile of the player.

What we do store

To make the game work (saving your progress and running the leaderboards) we store the bare minimum:

• A nickname you choose yourself. We ask that it not be your real name, and we block nicknames that look like personal data (for example, phone numbers).
• An anonymous device identifier (a random code). It is not linked to your identity and we never cross-reference it with anything.
• Your game progress: levels, stars, coins, scores, achievements, and match statistics.
• Your IP address, only temporarily and solely to prevent abuse (cheating, spam). It is discarded after a short period.

Advertising

Calculón is supported by advertising through Google AdSense, configured for a child-directed site:

• Ads are non-personalized: they are based on the content of the page, not on your activity or a profile about you.
• Ad requests are tagged as child-directed (child treatment under COPPA/GDPR), which disables personalization and remarketing by Google.
• Google may use limited cookies or technical identifiers for purposes such as frequency capping or fraud prevention. More information at how Google uses information from sites that use its services.

Leaderboards

Your nickname, your avatar, and your scores may appear in public rankings (Top and leagues). For this reason, your nickname must not contain personal data. Anyone can report an inappropriate nickname; after enough reports it is automatically hidden and replaced with "Anonymous player".

Your rights (GDPR)

• Deletion: you can ask us to delete all your progress and your nickname, from within the game itself or by writing to us.
• Contact: [email protected]

Because we don't store personal data, we cannot identify a person from what is stored; deletion is carried out against the anonymous device identifier.

Children

Calculón is designed for minors. We collect no personal data precisely to minimize any risk. If you are a parent or guardian and have any questions, please reach out at our contact email.

Changes

If we change anything in this policy, we will update this page and the date at the top.
