Include this information

• Seller OS version shown in the toolbar popup

Never email your AI API key, password, authentication cookie, or full buyer conversation.

Common fixes

• Reload Seller OS from chrome://extensions, then refresh existing Fiverr tabs.
• Confirm you are signed in to Fiverr and to any browser AI provider you selected.
• Open Settings to check your plan or change your AI pipeline.
• Use Stop All if a tab-based task appears stuck.

Refunds

For refund requests and timelines, see our Refund Policy, then email billing@sellerosforfiverr.com with your purchaser email, order reference, purchase date, and a short explanation.

Purchases and licenses

Paid checkout uses your Seller OS account: create or sign in at your account page with the same email you will use at checkout, and the purchase links to your account automatically. If you bought with a different email, email billing@sellerosforfiverr.com and we can link the purchase for you. For checkout, activation, renewals, and cancellations help, email billing@sellerosforfiverr.com. For privacy and data requests, including account deletion, email privacy@sellerosforfiverr.com.

Security

To report a security vulnerability responsibly, email security@sellerosforfiverr.com with a description and steps to reproduce. Please do not disclose the issue publicly until we have had a reasonable time to address it.

Email preferences

Product-update and promotional emails include an unsubscribe link. Billing, activation, refund, and security messages connected to a purchase are transactional and may still be sent when necessary.
