Support · updated October 3, 2026

Contact, in plain words.

The short version: Email support@meikucharts.com for product questions or technical help. Polar handles payment, refund and subscription questions.

Reporting a problem

Please include:

• The page URL.
• What you did — the steps that led to the problem.
• What you expected to happen.
• What happened instead, including any error message.

Share only the example data needed to explain the problem. A share link includes chart data after # — remove that part if you do not want to send the data. Never send passwords or sign-in tokens.

For billing or refund questions, contact support@polar.sh with your order reference. To manage or cancel a subscription, use the Polar customer portal with your checkout email address. Do not send your Pro key or card details in a support message.
