Hi Luis,

Sorry for your trouble here. Two out of your three requests already exist!

- History is available. Just click on the flag at the top of the menu bar.

- You can set notifications for edits and deletions from your user settings page. We do plan to add these by default for expenses you create in the future.

- However, we have no plans to add “permissions” around deletion – this is against our philosophy of sharing, and would make Splitwise very frustrating for users who saw errors they had no power to fix.

I hope this helps, and sorry for your negative experience.
