billsplitpro_glossaryAbout
BillSplitPro is a recurring-household-bill splitting engine for roommates. even_split and weighted_split divide a single bill cent-exactly by headcount or by arbitrary weights (room size, occupancy). split_utility_bundle handles a whole month's bills at once, letting each bill use its own method -- e.g. internet split evenly but electricity by occupancy. household_ledger takes a list of monthly bill entries across as many months as you like and computes each roommate's total paid, total owed, and net running balance -- balances always sum to zero for consistent inputs. settle_up runs a real greedy debt-simplification algorithm on those balances, minimizing the number of payments needed to zero the household out. billsplitpro_glossary defines the underlying terms. Not a payments product -- it computes who owes what and suggests settling transactions but does not move money.
Sources: Computed locally -- no dataset, no upstream calls. Splitting uses largest-remainder (Hamilton) apportionment so shares always sum exactly to the total; settle-up uses a greedy largest-creditor/largest-debtor debt-simplification algorithm adapted for recurring monthly household bills

- Even splitSplits a bill evenly among named roommates, cent-exact via largest-remainder rounding (shares always sum exactly to the total).

Documentation
Back to topWhat BillSplitPro is for
"Split the $90 internet bill evenly between three roommates", "split electricity by occupancy: two people in one room, one each in the others", "split internet evenly but electricity by occupancy this month", "here's three months of bills and who paid what, what's the running balance, who owes whom" — the recurring, month after month arithmetic of sharing a household's bills fairly, not just splitting a single one-off group tab.
What it does
even_split and weighted_split divide a single bill among named roommates — evenly, or in proportion to an
arbitrary weight such as room size or occupancy — using a largest-remainder apportionment method so shares
always sum EXACTLY to the total. split_utility_bundle handles a whole month's set of bills in one call, where
each bill can use its own method: split internet evenly across everyone but split electricity by occupancy, for
instance, in a single request. household_ledger is the core of the connector: feed it a list of monthly bill
entries — month, bill name, amount, who paid, and how it was split — across as many months as you like, and it
computes each roommate's total paid, total owed, and net running balance over the whole period; balances always
sum to zero for consistent inputs. settle_up runs a real debt-simplification algorithm on those accumulated
balances, computing the smallest practical set of direct payments to zero the household out — the same
algorithm family used for one-off group trips, adapted here for an ongoing household's recurring bills instead.
billsplitpro_glossary defines the underlying terms.
What it is not
Not a payments product — it computes who owes what and suggests settling transactions; it doesn't move any money or connect to any bank, card, or payment app. No currency is assumed anywhere: it computes in whatever units your numbers are already in. The debt-simplification algorithm is a well-known, widely used greedy heuristic (match the largest creditor against the largest debtor, repeat) rather than an exhaustive search for the mathematically smallest possible transaction count — for the vast majority of real households it produces the same result an exhaustive search would.

What BillSplitPro is. BillSplitPro is a connector (an MCP server and REST API) that AI assistants and personal agents call on your behalf to run a pure-compute household-bill-splitting or settle-up calculation. You interact with your assistant; the assistant sends us only the numbers needed for that one calculation.
What we receive. The arguments of each tool call — amounts, roommate names, weights, or a list of monthly bill entries with who paid and who shared them — the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant, and a Pro API key if you have one), and standard server logs. The "names" in a split are whatever labels you use (first names, initials, nicknames) — we have no way to know, and don't need to know, who they really are.
Everything is computed locally from the numbers you provide, and nothing is stored. There is no upstream call at all — this connector has no bundled dataset and no live lookups, it is pure arithmetic — and no request, including names, amounts, or the resulting splits, ledgers, and settlement transactions, is logged in request bodies, recorded, or used to train anything.
What we do not receive or store. We do not receive your conversation with the assistant, and we do not build a profile from your queries: each request is computed independently and nothing carries over between requests. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting-provider access logs, which contain IP addresses and request paths but not request bodies, are retained for up to 30 days for security and abuse prevention.
Sub-processors. None — every calculation runs locally with no dataset and no upstream call of any kind. Hosting: Vercel (United States regions).
Legal bases and your rights. Our processing is necessary to provide the service you request through your assistant. Because we store no personal data beyond short-lived logs, requests to access, correct or delete personal data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. We do not sell or share personal information and do not use your data to train models.
Children. BillSplitPro is a general-audience service operated by the adult using the assistant.
Changes. We will post changes here with a new effective date.
Terms of service
Back to topBillSplitPro — Terms of Service
Effective 28 September 2026. These terms govern use of the BillSplitPro connector ("the Service") operated by Unify Dynamics LLC ("we", "us").
- The Service. BillSplitPro is a pure-computation recurring-household-bill-splitting and debt-simplification calculator. It is accessed through an AI assistant or directly over MCP or HTTP, and performs no lookups and stores no data — every result comes directly from the numbers supplied in that request.
- Not a payments service. The Service computes who owes what and suggests settling transactions; it does not move money, connect to any bank or card, or verify that any suggested payment actually happened. Acting on a result (e.g. actually paying a roommate) is entirely up to you.
- Computational tool, not a guarantee of fairness. Splitting method (even, weighted, utility bundle) and settle-up results reflect the inputs and method you chose; the Service has no way to verify that the amounts, participants, weights, or names you provide are accurate or complete.
- Acceptable use. Automated use within the published rate limits is welcome.
- Availability. The Service is provided "as is" without warranty. We may change, limit or discontinue it at any time.
- Data. Our Privacy Policy describes what we process. In short: every calculation is computed locally from the numbers you provide, and nothing is stored.
- Pro keys. Optional Pro API keys are issued at our discretion, are personal to the holder and may be revoked for abuse.
- Liability. To the fullest extent permitted by law, Unify Dynamics LLC is not liable for any loss or dispute arising from use of, or reliance on, the Service, including any disagreement among roommates about a split, ledger, or settlement computed here. Our total liability is limited to US $100.
- Governing law. California law; venue in San Mateo County, California.
