Privacy policy

Who is responsible

The operator below is responsible for personal data processed through Deductidle:

What the game processes

When you test an example, request a hint, check answers or reveal a rule, the browser sends the relevant puzzle information to our server. This can include the day, stage, category, examples you tested and your answer choices. The server uses this information to run the game and return a result.

The game has no user accounts, advertising scripts or third-party analytics scripts. It does not maintain a server-side player profile or save your puzzle inputs in an application database. Technical request data is also processed by our hosting provider, as explained below. Please enter puzzle examples rather than personal or sensitive information.

Where the GDPR applies, we rely on our legitimate interest in providing a functioning, secure puzzle game (Article 6(1)(f)). Puzzle inputs are processed for the request rather than kept as a player history on the server.

Progress, preferences and cookies

The game uses local storage in your browser to remember daily stages, examples and answers, tries, strikes, hints, and results used to calculate your streak. It also remembers your chosen theme, sound setting and whether you dismissed the introduction. Practice rounds are not saved as daily progress.

These entries use names beginning with deductidle.. They have no automatic expiry and remain until you clear this site's data, your browser removes them, or a future version replaces them. Browser saves do not automatically sync between devices or domains.

The application does not set advertising or analytics cookies. Browser storage supports saved gameplay and the preferences you choose. Cloudflare may use necessary security cookies when protecting the site; see its cookie information.

To remove local saves, open your browser's site-data settings for deductidle.com and clear its stored data. This resets saved progress, streaks and preferences on that browser. Blocking storage may prevent progress from surviving a reload.

Hosting and technical requests

Cloudflare, Inc., 101 Townsend Street, San Francisco, CA 94107, USA, hosts and protects this website. It processes information such as your IP address, requested URL, request time, browser and device headers, and the data needed to handle a game request. Delivery, reliability and protection against abuse are our legitimate interests under Article 6(1)(f) GDPR.

Cloudflare operates a global network, so processing may take place outside the European Economic Area, including in the United States. Cloudflare describes its processing, retention criteria and international transfer safeguards in its Privacy Policy and Data Processing Addendum, including standard contractual clauses where applicable. Technical and security records may be retained for service operation, investigating abuse and meeting legal obligations; their retention depends on the service and purpose.

Contact and sharing

If you contact the operator, your email address and message are used to handle your request. This is based on our legitimate interest in responding to enquiries (Article 6(1)(f) GDPR), or Article 6(1)(b) when needed for a contract-related request. Correspondence is retained while needed to resolve the enquiry and any related legal obligations or claims.

Email sent to contact@deductidle.com passes through Cloudflare Email Routing and is delivered to the operator's Gmail inbox. Cloudflare and Google process the message and associated delivery information to provide these services. Google explains its processing, retention and international transfers in its Privacy Policy.

Sharing a result is your choice. The Share result button copies text to your clipboard; Save image downloads an image to your device. Pasting or uploading the result elsewhere shares it with the destination you choose. That destination's own privacy rules apply.

Your rights

Where the GDPR applies, you can request access, correction, erasure, restriction of processing and, where applicable, data portability. You can object to processing based on legitimate interests for reasons relating to your situation. Contact the operator above to make a request.

You may complain to a data protection authority, particularly in the country where you live, work or believe an infringement occurred. The European Data Protection Board maintains a directory of supervisory authorities.

We do not use your data for decisions with legal or similarly significant effects, or for advertising profiles. You do not need to provide an account identity to play; the technical requests described above are needed to deliver and evaluate the game.
