Privacy Policy
How Circle Lab collects, uses, shares, and protects information when you visit DrawPerfectCircle.com.
Effective July 18, 2026The important part: your circle drawing is evaluated in your browser and is not uploaded to Circle Lab.
The browser game has no account system, profile, chat, public posting, purchase flow, or user-upload feature. Circle Lab may process ordinary website logs and contact emails, and uses Google Analytics to understand traffic and feature usage. This policy explains those categories in detail.
Scope and Responsible Organization
This Privacy Policy applies to DrawPerfectCircle.com and the pages and browser-based features Circle Lab operates on that domain (the “Website”). Circle Lab is responsible for the processing described in this policy.
The Website may link to app stores, mobile apps, and other third-party services. Their own privacy policies apply to information they collect. This policy does not govern a separately distributed Android app unless its own listing or policy expressly incorporates this policy.
Information We Collect or Process
| Category | Examples | How it is obtained |
|---|---|---|
| Drawing and score data | Points in your stroke, calculated score, and session-best score. | Processed locally in temporary browser memory. Circle Lab does not receive the stroke or session score through the current browser game. |
| Technical and network data | IP address, browser and device type, operating system, requested URL, timestamps, referrer, language, and security or diagnostic events. | Automatically processed when your browser requests the Website, including by our hosting and security providers. |
| Usage and analytics data | Page views, session statistics, approximate location derived from network information, browser and device information, referring pages, and interactions with Website features. | Collected through Google Analytics and its cookies or similar identifiers, subject to applicable consent requirements and your settings. |
| Communications | Your email address, name if included, message contents, attachments, and our response. | Provided by you when you email Circle Lab or send a legal request. |
We ask that you not send sensitive personal information, government identification numbers, financial information, medical information, or information about a child unless it is necessary for a request and we specifically ask for it.
Google Analytics
Circle Lab uses Google Analytics 4 (“Google Analytics”), a measurement service provided by Google, to understand how visitors use the Website and to improve performance, content, and usability.
In a standard implementation, Google Analytics may collect the number of users, session statistics, approximate geolocation, browser and device information, page views, referrers, and configured interaction events. Google Analytics may assign a client identifier using a first-party cookie. Google describes its handling of this information in the Google Privacy Policy and its Analytics data safeguards.
Circle Lab does not intentionally send names, email addresses, circle-coordinate data, or other directly identifying account information to Google Analytics. The Website does not have user accounts. We do not intentionally use Website analytics for personalized or targeted advertising.
Consent: where applicable law requires consent for analytics storage or measurement, analytics should operate according to the visitor’s consent choice. Declining analytics should not prevent access to the drawing game.

- provide, operate, maintain, and secure the Website;

Retention, Security, and International Processing
Retention
Drawing and score information used by the current browser game remains in temporary page memory and is discarded when the page session ends or is refreshed. Technical logs are retained according to operational, security, and hosting-provider needs. Analytics information is retained according to the settings in Circle Lab’s Google Analytics property and Google’s applicable controls. Communications and legal records are kept for as long as reasonably necessary to answer the request, maintain business records, comply with law, and resolve disputes.
We may retain aggregated or de-identified information that no longer reasonably identifies you.
Security
We use reasonable administrative, technical, and organizational measures designed to protect information. No internet transmission or storage system is completely secure, so we cannot guarantee absolute security.
International processing
Circle Lab is located in the United States. Our providers may process information in the United States and other countries, which may have different data-protection laws than your country. Where required, we rely on recognized transfer mechanisms or other lawful safeguards.
Your Privacy Rights

To submit a request, email [email protected] with the subject Privacy Request. Describe the right you wish to exercise and the Website interaction involved. We may need to verify your identity and authority before completing a request. Authorized agents may submit requests where permitted by law.
We will not discriminate against you for exercising a privacy right. Some rights are subject to exceptions, and not every law applies to Circle Lab or every visitor.
