Terms of Service
Version 2026-08-26
What Ninepigs is
Ninepigs is a shared budgeting service. You create a household, invite the people you share money with, and record accounts, categories, recurring items, and transactions across repeating periods. Everyone in a household can see and edit that household's financial records.
Your account
You need a verified email address to sign in. Keep your password to yourself; you are responsible for what happens under your account. Use an address you control — invitations and account recovery both go through it.
Your household's data
What you record belongs to you. Anyone you invite into your household can read and change it, so invite only people you intend to share those records with. Removing someone from a household stops their access from that point on.
Availability
Ninepigs is offered as-is while it is being built. Features may change, and the service may be unavailable at times. Keep your own copies of anything you cannot afford to lose.
Ending your use
You can close your account at any time from Settings. We may suspend an account that is being used to harm the service or other people.
Changes to these terms
When the final terms are published, this version will be replaced and you will be asked to review and accept the new one. The version you accepted is recorded against your account, and it is the version shown at the top of this page on the day you accepted it.
