Question 1

Do Split and Business need the browser extension?

Accepted Answer

No. Both work on the website. Split uses private personal links without sign-up; Business uses individual accounts and business-specific team access.

Question 2

Can I recover a Split group with only my email?

Accepted Answer

No. Set up recovery in advance under Members, then keep the recovery key safe. Recovery requires the emailed one-hour link and that key. Otherwise, ask a group admin for a new personal link.

Question 3

Does recording a Split repayment move money?

Accepted Answer

No. Pay separately, then record the repayment. Opening a payment app does not confirm success. If the group requires recipient confirmation, the recipient must confirm receipt before balances change.

Question 4

Why is my Business workspace read-only or missing an action?

Accepted Answer

Your role, enabled modules and subscription status determine available actions. Ask the owner to review Team and Subscription. When billing enforcement is active, an expired plan can make the workspace read-only while keeping records viewable and downloadable.

Question 5

Is a Business change marked Not saved yet available to my team?

Accepted Answer

It has not been confirmed as saved to the server. Check Unsent changes on the device where you entered it, restore your connection and use the offered send, retry or sign-in action.

Question 6

How do I open the Kernel Extension panel?

Accepted Answer

Press F12 to open DevTools, then click the "Kernel Extension" tab in the panel bar. Or press Ctrl+Shift+Y to jump directly to the panel. You can also click the K icon in the browser toolbar to open it as a standalone tab.

Question 7

Does the extension work without internet?

Accepted Answer

Most tools work completely offline — Console, Network, DOM, Storage, Mock API, API Tester, Colors, Fonts, and more. Only Certificate Inspector (crt.sh), DNS Leak Checker (ipify.org) and HSTS check (hstspreload.org) make external network requests, and only when you trigger them.

Question 8

Where are mock rules and API collections stored?

Accepted Answer

In chrome.storage.local — on your device only. Nothing is ever sent to a server.

Question 9

Why does the Console tab show no logs?

Accepted Answer

The content script is injected on page load. If you installed the extension after loading a page, reload that page so the script can attach.

Question 10

Can I use the extension on chrome://... or edge://... pages?

Accepted Answer

No — browser extensions cannot inject scripts into browser-internal pages. The extension works only on regular http:// and https:// pages.

Question 11

How do I report a bug?

Accepted Answer

Open an issue on GitHub with steps to reproduce, your browser version, and the extension version from the about section.
