Ownership you can point to
Your expense history has an address.
Not in a mystery database. Not behind an export request. It lives as readable files in the private repository created for your group.
Private repository
The creator owns the repository and invites trusted GitHub collaborators.
Portable, readable JSON
Group settings and expenses use documented files, not a proprietary data format.
History included
Git records how files change, while BranchBalance prevents silent conflict overwrites.
Where your data goes
Your phoneBranchBalance calculates balances and keeps credentials securely on-device.
GitHub API
Your repositoryGitHub provides storage, identity, membership, and the source-of-truth history.
No BranchBalance application server in the middle
More than who owes whom
A clear view of life together.
Use it for a weekend away, a shared flat, or the everyday costs that are easier when everyone can see the same picture.
02 / Spend intentionally
See where the money went.
Follow a group budget, optional category limits, card-or-cash totals, and daily guidance across a trip.

03 / Stay in control
Trust through visibility.
Membership comes from GitHub collaborators, writes use explicit conflict checks, and your repository remains the authority.
