Privacy Policy
Last updated October 16, 2026
Who we are
In this policy, “we,” “us,” and “our” refer to KinPayroll Corporation, the company that operates KinPayroll and is responsible for the data described below.
What we collect
When you create an account we store your name and email. As you use KinPayroll you provide information about the household you manage — the employer (your family member), their caregiver, pay rates, hours, and the tax details needed to produce payroll and tax documents. Caregiver Social Security numbers, when provided, are encrypted with AES-256-GCM and can be decrypted only by our servers to prepare tax forms.
How we use it
We use your information solely to provide the service: calculating payroll and withholdings, generating pay stubs and tax documents, and managing your subscription. We do not sell your data.
Service providers
We rely on Supabase (database, authentication, file storage), Stripe (payments), and Resend (transactional email). They process data on our behalf under their own security and privacy commitments. Each household's data is isolated at the database row level.
How long we keep it
Payroll and tax records have to be kept. We keep the payroll records and the tax documents we generate for you — pay stubs, Form W-2, Schedule H and the Caregiving Payment Summary — for at least seven years after the tax year they cover, which is the period the IRS expects a household employer to be able to produce them for. We keep them for that period even if you stop using KinPayroll, and we apply the same seven-year period to the account information attached to them.
Your choices
Email support@kinpayroll.com and we will send you a copy of your data, stop your subscription, or close your account — a person handles each request by hand. We will delete anything we are not required to keep. What we cannot delete on request is the payroll and tax-record set described above: deleting it inside the seven-year window would destroy records you may need, so it stays until that period is up and is then removed.
KinPayroll is not a law firm or an accounting firm and does not provide tax or legal advice.
