Email is the only support channel we run. There is no phone line, no live chat and no support ticket portal yet — a message to the right inbox reaches the small team that builds the product, and we answer in the timeframes listed below.
Pick the channel that matches your question. Sending billing issues to the support inbox or support questions to the legal inbox only slows things down.

Contact questions
How fast do you reply?
Product support and billing messages are answered within 1–2 business days. Privacy and data-deletion requests can take up to 30 days because they may require verification. DMCA notices are reviewed within 5 business days.
Do you offer phone support or live chat?
Not yet. Email is the only support channel, and it is monitored by the people who build the product. We do not run a call center, so a phone number would be misleading.
How do I request a refund?
Email billing@stemextractor.com with the checkout email, invoice ID and the job ID if a separation is involved. Your first purchase — including the $2.90 Trial Pack — is covered by the 14-day money-back guarantee. The refund policy explains the details.
Where do I report copyright infringement?
Email dmca@stemextractor.com with the information required by the DMCA: identification of the work, identification of the material, your contact details, a good-faith statement, a statement under penalty of perjury and your signature. The terms of service describe the full process.
