MechSim ("we", "us", "the Service") is a free, browser-based kinematic mechanism simulator. We are committed to protecting your privacy. This policy explains what information we collect, how we use it, and your rights regarding that information.
Data processed locally. All mechanism data — pins, links, simulation state, recorded kinematic data, and exported files — is processed entirely in your browser. We do not transmit, store, or have access to your mechanism designs or simulation data.
Automatically collected information. When you visit our website, we may collect standard web analytics data through third-party services:
We use Google AdSense to display advertisements. Google and its partners may use cookies and similar technologies to serve ads based on your prior visits to this or other websites. You can opt out of personalized advertising by visiting Google Ads Settings or www.aboutads.info.
For users in the European Economic Area (EEA) and the United Kingdom, we comply with the IAB Transparency and Consent Framework (TCF v2.3). You may be asked for consent before personalized ads are served.
MechSim itself does not set cookies. However, Google AdSense and analytics services may set cookies on your device. These are used for:
You can control cookies through your browser settings. Disabling cookies may affect the ads you see but will not affect the simulator's functionality.
We do not operate user accounts or databases. Your mechanism files (.mechsim.json) and exported CSV data exist only on your device. We have no ability to access, recover, or delete your local files.
MechSim is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information through our advertising partners, please contact us.
Depending on your location, you may have the right to access, correct, or delete personal data collected by our third-party partners. Since MechSim does not collect personal data directly, these rights apply primarily to data collected by Google AdSense. Please refer to Google's Privacy Policy for details.
We may update this privacy policy from time to time. Changes will be posted on this page with an updated revision date. Continued use of the Service after changes constitutes acceptance of the revised policy.
