Product and account support

When reporting an issue, include the tool name, approximate time, steps taken, and the message shown on screen. For account or order questions, include the order, task, or user reference, but never send passwords, verification codes, private keys, or complete payment credentials.

  • Tool failures, unexpected results, or download problems.
  • Login, account, credits, subscriptions, orders, or refund questions.
  • Feature ideas, tool requests, and accessibility feedback.

Privacy and security reports

If you believe you found a vulnerability, data exposure, or unauthorized access, use “Security report” in the subject and provide reproducible details without including another person’s sensitive data. Do not publicly exploit a vulnerability or access data that does not belong to you.

Security reports are prioritized according to impact and urgency. We may contact you for additional information.
03

Business and advertising

Business inquiries should include the organization, product or service, destination page, requested placement, campaign period, and contact details. VisTool does not accept unlawful, misleading, impersonating, malicious, or clearly irrelevant promotional content.

04

Response expectations

We review messages within a reasonable time but do not guarantee a fixed response time. Duplicate messages may not speed up handling. Account requests that require identity verification may need to be completed through an authenticated account flow.
