OneManOS Terms of Service
Version 1.0 · Effective August 14, 2026
These terms are an agreement between you (the business subscribing to OneManOS) and OneManOS, a sole proprietorship operated in Ontario, Canada by Anderson dos Santos Ferreira. By creating an account or using the service you agree to them and to the Privacy Policy.
What the service is
OneManOS is bookkeeping and job-management software for small construction and trades businesses: quotes, invoices, expenses, receipts, payroll records, bank-feed reconciliation, scheduling, and tax-oriented reports for Canadian sole proprietors.
What the service is not
OneManOS is software, not a professional service. It does not provide accounting, tax, or legal advice.
Figures the app produces — tax estimates, HST amounts, payroll withholdings, CRA form values, reserve suggestions — are calculations from the data you entered, provided to help you organize, not professional determinations. You are responsible for the accuracy of what you enter, for reviewing what you file, and for your own filing and record-keeping obligations (including the CRA’s six-year record retention rule). For decisions that matter, verify with a qualified accountant or the CRA.
Your account
- You must provide accurate information and keep your login credentials secure.
- You are responsible for activity under your account.
- You confirm you have the right to enter the information you put into the service — including your clients’, employees’, and subcontractors’ details.
Your data
Your records belong to you. We process them only to provide the service, as described in the Privacy Policy. You can export your data, and you can permanently delete your account and everything in it at any time (Settings → Security). We never sell your data.
Bank connections
Bank feeds are provided through Plaid Inc. and are subject to your consent given when connecting an account. Bank-reported data can lag or be revised by your bank; the feed is an aid to your bookkeeping, not a statement of record from your bank.
Acceptable use
Don’t use the service to break the law, to store data you have no right to hold, to probe or disrupt the service’s security, or to resell access. We may suspend accounts that do.
Subscription and cancellation
Paid plans are billed as presented at purchase. You can cancel at any time; cancellation stops future billing. Deleting your account permanently destroys your data as described in the Privacy Policy — export first.
Availability and changes
We aim to keep the service available and your data safe, but the service is provided “as is” without warranties of uninterrupted availability. Features may change as the product develops; we won’t materially reduce what you paid for within a paid period.
Limitation of liability
To the maximum extent permitted by law, our total liability for any claim relating to the service is limited to the amount you paid for the service in the twelve months before the claim arose. We are not liable for indirect or consequential losses, or for outcomes of filings and business decisions you make using the software. Nothing in these terms limits liability that cannot be limited under applicable law.
Termination
You may stop using the service at any time. We may terminate accounts for material breach of these terms with notice where practicable. On termination you retain the right to export your data for a reasonable period before deletion, except where you have already deleted the account yourself.
Governing law
These terms are governed by the laws of Ontario and the federal laws of Canada applicable in it. Disputes will be resolved in the courts of Ontario.
