Privacy Policy

This Privacy Policy explains how Vizvero handles information when you use vizvero.app. Vizvero is designed as a browser-first chart-making product. An account is optional for the core chart-making and export workflow.

The most important distinction is between the data you put into a chart and routine information involved in delivering a website. The chart editor is designed so your chart data can be processed in your browser, while normal web infrastructure may still process connection and security information.

In the current product, data you paste into the editor or import from a CSV file is read and processed in your browser for chart creation. Chart rendering and PNG, SVG, and MP4 export are also performed in the browser.

The chart-making workflow does not intentionally upload the contents of your chart data to Vizvero servers solely to create or export a chart. Signing in does not by itself upload the chart data in your current browser editor. If you explicitly choose Save while signed in, Vizvero stores the saved chart document and its management name so the chart can be retrieved as an account feature. If you then enable sharing, anyone who has the generated share link can view the latest version you have successfully saved.

You should still avoid entering highly sensitive, regulated, or confidential information unless you are comfortable processing it on the device and browser you are using.

If you choose to sign in, Vizvero stores account information needed for authentication, such as your email address, display name, authentication-provider identifiers, verification records, and session records. Google may provide profile information when you use Google sign-in. Email verification codes are delivered using an email service provider.

If you contact Vizvero at support@vizvero.app, the message may include your email address, name, message content, attachments, and any other information you choose to provide. That information is used to respond to the request, diagnose problems, protect the service, and maintain a reasonable support record.

Like other websites, the infrastructure used to deliver Vizvero may process routine request information such as IP address, browser or user-agent information, requested URLs, timestamps, and security or error information.

Vizvero is hosted and delivered using Cloudflare infrastructure. Cloudflare may process connection and security data as part of delivering and protecting the site under its own terms and privacy practices.

Vizvero uses local browser storage for functional preferences such as the selected light or dark theme and for automatic maker drafts. Local storage stays on the device and browser you are using and is technically different from a cookie.

Maker drafts are stored locally by chart type so refreshing or leaving a maker can restore recent work. Resetting a chart clears that maker draft. Saved-chart recovery uses a separate browser-storage namespace so an anonymous maker draft cannot silently replace a cloud-saved chart.

Vizvero uses Google Analytics on the canonical production website at vizvero.app to understand aggregate traffic and how product features are used. Google Analytics is not loaded on localhost, Cloudflare workers.dev addresses, or other non-canonical preview and test hostnames.

Analytics events may include page views, the chart type being used, how data was entered, the number of rows, columns, or rendered series, which editor section was opened, animation choices, and export format. Vizvero does not intentionally send chart cell values, pasted CSV contents, column names, chart titles, subtitles, source text, filenames, email addresses, or the complete ChartDocument to Google Analytics.

Google Analytics may use first-party cookies and related identifiers to distinguish visits and measure usage. Advertising storage, advertising user data, advertising personalization, and Google Signals are disabled in Vizvero's analytics implementation. Vizvero does not use Google Analytics for behavioral advertising.

The analytics implementation includes Google Consent Mode controls so analytics storage can be changed if Vizvero later introduces consent controls for particular regions or product requirements.

Vizvero does not sell personal information. Information may be handled by service providers that are necessary to operate and understand the site, such as hosting, security, email, and analytics providers, including Google Analytics.

When you enable a public share link, the chart data contained in the latest saved version becomes available to anyone who obtains that link. Share links are unlisted rather than access-controlled; disabling the link invalidates that token and re-enabling sharing creates a new token.

Information may also be disclosed when reasonably necessary to comply with law, respond to valid legal process, protect the service or users, investigate abuse, or enforce applicable terms.

Unsaved maker drafts remain on your device until reset, replaced, or cleared through browser/site-data controls. Charts you explicitly save while signed in are retained with your account so the saved project can be retrieved and updated. Active and revoked share-link records may be retained with a saved chart, including aggregate view count and first/last viewed timestamps. Deleting a saved chart removes its share records through database cascade.

Google Analytics and other service providers may retain analytics or technical data according to the retention settings and policies applicable to those services. Support correspondence may be retained for as long as reasonably necessary to respond, keep records, prevent abuse, or meet legal obligations.

Vizvero uses reasonable technical measures appropriate to a small browser-based web product, but no website, device, transmission method, or storage system can be guaranteed completely secure.

Vizvero can be accessed from different countries. Infrastructure and service providers may process routine information in locations other than your own. Where applicable, their processing is governed by their own contractual and legal safeguards.

Depending on where you live, you may have legal rights concerning personal information, including rights to request access, correction, deletion, or information about processing. To make a request, contact support@vizvero.app.

Optional account records and charts you explicitly save are stored server-side. Depending on where you live, applicable rights may include requesting access to or deletion of that stored information. Unsaved local drafts remain controlled by your browser storage.

Vizvero is not directed to children under 13. If you believe a child has created an account or otherwise sent personal information directly to Vizvero, contact us so the request can be reviewed.

This policy may change as Vizvero adds features or as legal and operational requirements change. The date at the top of the page will be updated when the policy is materially revised.
