Privacy notice

Your in-progress diagram (shapes, connectors, labels) is saved to your browser's session storage on your device only, so it survives a page reload within the same tab but is cleared when you close the browser. If you choose to sign in and save a diagram to your account, that diagram and your email address are stored securely on our servers so you can access them later, and only you can see them.

You can use Mesh Rhino fully without ever signing up. Creating an account is optional and only needed if you want to save a diagram to your profile so it's there when you come back. An account stores just your email address and the flowcharts you choose to save, nothing more. You can sign out and delete your account at any time.

Mesh Rhino uses cookies and similar technologies for two purposes:

Analytics. We use Google Analytics to understand how the site is used (pages visited, session duration, approximate region). Google Analytics sets cookies on your device to collect this information.

Advertising. We display ads through Google AdSense. Google and its third-party partners may use cookies to serve ads based on your prior visits to this and other websites, and to measure the performance of those ads. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and other sites on the internet.

You can opt out of personalised advertising by visiting Google Ads Settings, and opt out of Google Analytics by installing the Google Analytics opt-out browser add-on. You can also disable or delete cookies in your browser settings at any time. Third-party vendors, including Google, use cookies to serve ads based on a user's previous visits to this website or other websites. You may review Google's advertising privacy practices at policies.google.com/technologies/ads.

The only first-party persistence Mesh Rhino uses is your browser's session storage, purely to autosave your current diagram between reloads. Clearing your browser data or using a different browser/device will not carry that diagram over. Export to JSON first if you want a portable backup.

Files you export (JSON, SVG, or PNG) are generated entirely in your browser and saved directly to your device. We never see, store, or have access to exported files.

This notice reflects the app's current design, including optional accounts and the cookies described above. If Mesh Rhino ever changes how it handles your data, this page will be updated to explain exactly what changes and why.
