Privacy Policy

Last updated August 17, 2026

The Silo (buildyoursilo.com and the companion iOS app) is built on one idea: your household's numbers belong to your household. This policy says what we collect, what we do with it, and — mostly — what we don't do.

The short version

• No bank account linking. The Silo never connects to your bank, card issuer, or broker, and never asks for their credentials. Every number in your Silo is one you typed in.
• No selling, no ads, no trackers. We don't sell or share your data for marketing, we show no ads, and we run no third-party analytics or tracking scripts. There is nothing on the page but the app.
• Your data is yours. Delete your account and your household's data is deleted with it.

What we collect

Account information. Your name, email address, and a password (stored only as a cryptographic hash). If you enable two-factor authentication, its secret is stored encrypted.

The numbers you enter. Accounts, balances, transactions, debts, budgets, savings goals, property values, and — if you use the business tools — your customers and invoices. All of it is entered by you or a member of your household; none of it comes from a financial institution.

Billing. Subscription payments are processed by Stripe. Your card details go directly to Stripe and never touch our servers; we keep only a reference to the Stripe customer record and your subscription status.

Operational records. Standard server logs and an audit trail of account-level events (sign-ins, invitations, subscription changes), kept for security.

What we use it for

Running The Silo — and nothing else. Your data powers your own dashboards, projections, and notifications. We send transactional email (password resets, invoices you choose to send, notification digests you enable) and nothing promotional without your say-so.

Who can see it

Members of your household see your household's shared books — that's the point. Anything you mark private stays visible only to you. Our processors see only what they need to do their jobs: Stripe (payments), and Amazon Web Services (hosting and email delivery — data encrypted in transit and at rest). We disclose data beyond that only if the law requires it.

The iOS app

The companion app is a window onto the same service — it stores your session on the device and nothing else. Face ID / Touch ID unlocking happens entirely on your device through Apple's own mechanisms; biometric data never reaches us. The app contains no ads, no analytics, and no tracking.

Cookies

Two, both essential: a session cookie that keeps you signed in and a security token that protects forms. No advertising or cross-site cookies of any kind.

Retention and deletion

We keep your data while your account exists. Delete your account (or ask us to) and your household's data is removed from the live system; encrypted backups age out on a short rolling window. Paid-invoice records your customers hold are, of course, theirs.

Children

The Silo is not directed at children under 13, and we don't knowingly collect their information.

Changes

If this policy changes in a way that matters, we'll say so plainly on this page and, for significant changes, by email to account holders.
