Privacy Policy

1. Overview and Core Principle

WordSolver does not collect personal data. This is not a qualified statement with exceptions and fine print — it is a straightforward fact about how the site is built and operated. We do not require accounts, we do not ask for email addresses, we do not collect names, and we do not track individual users across sessions. The solvers run entirely in your browser using client-side JavaScript. Your guesses, percentages, game state, and answers never leave your device. No data is sent to our servers during gameplay or solver use. When you use the Colordle Solver, the color database is loaded into your browser's memory and all Delta E calculations happen locally. When you use the Colorfle Solver, the combination matching and feedback elimination run entirely on your machine. Your puzzle-solving activity is invisible to us by design.

We believe that privacy is not a feature you bolt on after the fact — it is a core design principle that should inform every decision about how a website is built. Every architectural choice we made for WordSolver was evaluated through the lens of data minimization. We collect the absolute minimum amount of data necessary to operate the site and understand aggregate traffic patterns. We do not collect any data that could identify you personally, link your visits across sessions, or build a profile of your puzzle-solving behavior. This approach sacrifices some features — we cannot offer personalized recommendations, persistent leaderboards, or social features — but we believe that sacrifice is worth making to build a tool that people can trust with their browsing habits.

This privacy policy exists not because we have complex data practices to disclose, but because transparency is a virtue regardless of how simple the truth is. You deserve to know exactly what happens when you visit WordSolver, what data flows where, and what choices you have. The sections below cover every aspect of data handling in detail. If anything is unclear or if you have questions that this policy does not address, email us at hello@wordsolver.tech and we will provide a direct, honest answer.

2. Data Collection

WordSolver collects no personal data. To be explicit about what this means, here is an exhaustive list of the data we do not collect: we do not collect names, email addresses, physical addresses, phone numbers, dates of birth, or any other personal identifiers. We do not collect IP addresses for tracking purposes (our content delivery network processes IP addresses as part of serving pages, but we do not use them for tracking or analytics). We do not collect browser fingerprints, device identifiers, or any other technology that could be used to identify you across visits. We do not collect information about your puzzle-solving behavior — what colors you guess, what percentages you enter, what answers you look up, or how long you spend on each page.

The daily answer pages are precomputed at build time. This means the HTML that contains the answer is generated on our build server before the page is served to you. When you visit the daily answer page, your browser loads a static HTML file — no server-side processing occurs, no database queries run, and no user-specific information is generated or logged. The answer data is computed using the same algorithms the official games use, applied to the current date, and baked into the page during the build step. Your visit to the answer page is indistinguishable from a visit to any other static page on the site. There is no server-side session, no request log that ties your visit to your identity, and no mechanism for connecting your answer-page visit to your solver usage.

The unlimited practice modes generate puzzle data locally in your browser using client-side JavaScript. The target colors, mixing parameters, and game state exist only in your browser's memory and are never transmitted to our servers. If you close the browser tab, navigate away, or refresh the page, the game data is lost permanently. We cannot retrieve it because we never had it. This ephemeral design is intentional — it means your practice habits are entirely private and cannot be reconstructed after the fact.

3. Browser Storage and Local Data

WordSolver uses browser local storage sparingly and only for essential site functionality. The solver components may use local storage to maintain your current session state — the colors you have guessed, the percentages you have entered, and the filtered candidate list — so that if you accidentally scroll or switch tabs and return, your work is preserved. This data is stored on your device only and is never transmitted to our servers. You can clear this data at any time through your browser's settings without affecting the functionality of the site. Clearing local storage will reset any in-progress solver sessions, which is the same behavior you get by refreshing the page.

The unlimited play modes may use local storage to maintain your current game state within a single browser session. This prevents the game from resetting if you accidentally navigate away and return using the browser's back button. The stored data consists of the target color, your guesses so far, and any feedback you have received. None of this data leaves your device. We deliberately chose not to implement persistent game state across sessions because doing so would require either a server-side account system or a local storage mechanism that could be used to build a profile of your playing habits over time. The ephemeral approach — data exists only within a single browser session — eliminates this privacy risk entirely.

We do not use browser storage for tracking, fingerprinting, or user identification. The site does not write unique identifiers to local storage that could be used to recognize you on subsequent visits. The site does not share local storage data with any third party. The site does not use the Storage API in ways that are not directly related to the functionality of the solver or game components you are actively using. If you prefer to block local storage entirely, the site will still function correctly for most features — you will just lose the convenience of session persistence if you navigate away from a solver mid-session.

4. Cookies

WordSolver uses minimal cookies for essential site functionality only. We do not use advertising cookies, marketing cookies, or third-party tracking cookies. The cookies set by the site are limited to maintaining basic preferences and ensuring the solvers work correctly during a single session. No cookie data is shared with third parties under any circumstances. If you have configured your browser to block all cookies, the site will still function correctly for the most part — the solvers do not depend on cookies to operate, and the daily answer pages are entirely static.

Specifically, the cookies we may set include: a session cookie that maintains your browsing state during a single visit (this cookie expires when you close your browser), and preference cookies that remember settings like your preferred view mode on the archive pages. These cookies contain no personal information and serve purely functional purposes. They do not track your behavior, they do not identify you across visits, and they are not accessible to any third party.

We do not use cookies for fingerprinting, cross-site tracking, or user identification. The site does not integrate with any advertising networks, social media platforms, or data brokers that might use cookies to build profiles of your browsing behavior across different websites. Our use of cookies is strictly functional and minimal, consistent with the site's philosophy of collecting no personal data. If you want to see exactly which cookies are set during your visit, use your browser's developer tools to inspect the cookie storage for wordsolver.tech. You will find either no cookies or a small number of functional cookies with no tracking content.

5. Analytics

We use standard web analytics to understand which pages are most visited and how the site performs overall. This analytics data is aggregated and cannot be linked to individual users. We do not use advertising trackers, social media pixels, or any third-party tracking scripts beyond basic anonymous page view counting. The analytics we collect tell us things like "the Colordle Solver page received 5,000 visits yesterday" and "most visitors come from the United States and Japan." They do not tell us who you are, what colors you guessed, or how you solved any particular puzzle. We believe that understanding aggregate traffic patterns is necessary for maintaining and improving the site, but that individual user behavior is none of our business.

The analytics data we collect includes: page view counts (how many times each page was visited), referral sources (how visitors found the site — search engines, direct links, or social media), approximate geographic regions (country or city level, derived from IP address but not stored in identifiable form), and device categories (mobile, desktop, or tablet). We do not collect: individual IP addresses, browser fingerprints, user agents that could identify specific devices, or any data that could be used to track a single user across multiple visits. The analytics service we use anonymizes IP addresses before processing, meaning the full IP address is never stored or available for analysis.

You can opt out of analytics tracking by using a browser extension or privacy setting that blocks analytics scripts. This will prevent any analytics data from being collected during your visit. The site will function identically with or without analytics tracking enabled. We respect your choice to browse without being tracked, and we have designed the site to work perfectly even if you block all tracking scripts. If you want to verify that analytics scripts are not running, check your browser's network tab — you should see either no requests to analytics domains or blocked requests, depending on your privacy setup.

6. Third Parties

The site is hosted on Cloudflare Pages, which processes basic request data such as IP addresses and browser types as part of content delivery. Cloudflare's privacy policy governs that processing. Cloudflare acts as a content delivery network and security provider — it serves our static pages to visitors quickly and protects the site from abuse, but it does not collect data on our behalf beyond what is inherent in the HTTP request itself, which Cloudflare processes automatically as part of serving any website. We do not share any user data with Cloudflare beyond what is inherent in the HTTP request itself.

We do not integrate with any other third-party services that collect personal information. There are no social media embeds, no comment systems powered by external providers, no payment processors, and no third-party analytics beyond the basic anonymous page view tracking described in the analytics section above. The site is intentionally self-contained. This decision limits our ability to add certain features — for example, we cannot offer social sharing buttons or embedded comment threads — but it ensures that your interaction with WordSolver involves as few third parties as possible.

Google Fonts is used to load the Inter and Outfit typefaces. When your browser loads these fonts, it makes a request to Google's font servers. Google may log these requests as part of their standard font delivery service. This is the only third-party resource loaded by the site that involves any interaction with an external server. If you prefer to avoid this, you can configure your browser to block external font loading — the site will fall back to system fonts and remain fully functional. The Google Fonts requests do not include any data about your puzzle-solving activity, your visit history, or any personal information beyond what is necessary to deliver the font files.

7. Children's Privacy

WordSolver does not knowingly collect personal information from children under the age of 13. Because we do not collect personal information from anyone — adults or children — this policy is satisfied by default. We do not ask for age, we do not gate access based on age, and we do not serve content that is inappropriate for children. Color puzzle games are inherently family-friendly, and the tools on this site — solvers, answer pages, and unlimited practice modes — are suitable for users of all ages. There is no user-generated content, no chat functionality, and no social features that could expose children to harmful interactions.

We do not use tracking technologies that could create profiles of children's browsing behavior. We do not serve targeted advertising, including behaviorally targeted ads, which is the primary concern of children's privacy regulations like COPPA. We do not use persistent identifiers to track children across sessions. The site's design — no accounts, no persistent data, no tracking — inherently complies with the spirit and letter of children's privacy regulations. If you are a parent and have concerns about your child's use of this site, you can review the site yourself, inspect the network requests in your browser's developer tools, and verify that no personal data is being collected. We are also happy to answer specific questions via email.

8. Your Rights Under Data Protection Laws

Depending on your jurisdiction, you may have specific rights under data protection laws such as the General Data Protection Regulation (GDPR) in the European Union, the California Consumer Privacy Act (CCPA) in the United States, or similar legislation in other regions. These rights typically include the right to access, correct, delete, or port your personal data, the right to object to processing, the right to restrict processing, and the right to withdraw consent. Because we do not collect personal data, most of these rights are moot — there is no personal data to access, correct, delete, or port. However, you always have the right to contact us with questions about our data practices, and we are committed to providing transparent and honest answers.

If you believe that any data covered by data protection legislation has been collected inadvertently — for example, if you included personal information in a support email — you have the right to request its deletion. We will comply with such requests promptly, typically within 48 hours. To make a request, email hello@wordsolver.tech with the subject line "Data Deletion Request" and specify the information you want removed. We will confirm the deletion once it is complete. We retain support emails only for as long as necessary to resolve the issue they describe, after which they are permanently deleted from our inbox and any backup systems.

We do not process personal data for automated decision-making, profiling, or any purpose that could significantly affect you. The site does not use personal data to determine what content to show, what features to enable, or what advertisements to display. There is no personalization engine, no recommendation algorithm, and no user segmentation. Every visitor sees the same site with the same features, regardless of their browsing history, geographic location, or personal characteristics. This uniformity is a feature, not a limitation — it means there are no hidden variables influencing your experience, no filter bubbles, and no algorithmic curation. What you see is what everyone sees.

9. Data Retention and Deletion

Since we do not collect personal data, there is nothing to retain or delete. Game state and solver inputs exist only in your browser's memory and are lost when you close the tab or navigate away. The unlimited play modes do not persist data between sessions by design. If you want a record of your solver session, take a screenshot before closing the page. We cannot retrieve any data about your past sessions because we never had that data in the first place.

The anonymous analytics data we collect is retained for up to 26 months, which is the default retention period for the analytics service we use. This data consists of aggregate page view counts, referral sources, and approximate geographic regions. It cannot be used to identify individual users, and we have no ability to link it to specific browsing sessions or devices. After the retention period, the data is automatically deleted by the analytics provider. We do not export, download, or create secondary copies of analytics data. It exists within the analytics platform and is subject to that platform's deletion schedule.

If you have any concerns about data that might exist in our analytics, you can exercise your right to opt out by using a browser extension or privacy setting that blocks analytics scripts. This will prevent any analytics data from being collected during your visit. The site will function identically with or without analytics tracking enabled. We respect your choice to browse without being tracked, and we have designed the site to work perfectly even if you block all tracking scripts.

10. Security

We take reasonable measures to protect the integrity and security of the site. The site is served over HTTPS, which encrypts all data in transit between your browser and our content delivery network. The code is stored in a version-controlled repository with access restricted to authorized contributors. We do not store sensitive data on our servers because we do not collect sensitive data in the first place. The most effective security measure for personal data is not to collect it at all, and that is the approach we have taken.

In the event of a security incident affecting the site, we would notify affected users through a banner on the site and update this privacy policy with details of the incident and our response. Because we do not collect personal data, the scope of any potential data breach is inherently limited. A breach could affect the site's code or the content delivery infrastructure, but it would not expose personal data because we do not have personal data to expose. We regularly review the site's security posture and apply updates to dependencies as vulnerabilities are discovered. The site uses Cloudflare's built-in security features, including DDoS protection and bot mitigation, which help prevent unauthorized access and abuse.

11. Changes to This Policy

We may update this privacy policy from time to time to reflect changes in our practices, technology, or legal requirements. When we make changes, we will update the "Last updated" date at the top of this page. Material changes will also be noted with a brief summary at the bottom of this section. Continued use of the site after changes constitutes acceptance of the updated policy. If you have questions about any changes, email hello@wordsolver.tech and we will explain what changed and why.

Historical changes: This policy was last updated in January 2025 to add sections on children's privacy, data protection rights, and security practices, and to clarify our use of Google Fonts as the only third-party resource that involves external server requests. No substantive changes to our data collection practices have been made since the site's launch — we still collect no personal data, use no advertising trackers, and run all solver computations locally in your browser.

12. Contact About Privacy

If you have questions about this privacy policy, want to exercise your data protection rights, or have concerns about how the site handles data, email us at hello@wordsolver.tech. We review privacy-related inquiries with priority and aim to respond within 24 hours. For data deletion requests, include "Data Deletion Request" in the subject line. For general privacy questions, include "Privacy Inquiry" in the subject line. We take privacy seriously not because we are legally required to, but because we believe it is the right way to build a tool that people can trust. Your confidence in the site's privacy practices matters to us, and we are always willing to explain our approach in detail.

If you are a privacy researcher, regulator, or advocate and want to audit the site's data practices, we welcome your scrutiny. The site's static nature and minimal data footprint make it straightforward to verify our claims: inspect the network requests in your browser's developer tools, review the cookie and storage access in your browser's privacy settings, and examine the page source to confirm that no tracking scripts are loaded beyond the basic analytics described in this policy. If you find anything that contradicts what this policy states, please let us know and we will investigate and correct it immediately.
