Effective Date: August 8, 2026
The shorestack Books application ("we," "us," or "our") is a product of Days Management LLC. This Privacy Policy explains how the shorestack Books macOS desktop application ("the App") handles your information. The short version: your books live on your Mac, in files you control, and we cannot see them. The App has no user accounts, no analytics, and no cloud copy of your financial data.
Everything you enter or import — transactions, journal entries, invoices, bills, vendors, customers, reports — is stored in company files (SQLite databases) on your Mac, by default under ~/Library/Application Support/shorestack Books/. You can store a company file anywhere you choose. We do not operate a server that receives, stores, or can access this data.
Backups are snapshot copies of your company file saved to a folder you choose (which may be a folder synced by a service you use, such as Google Drive — in that case, that service's own policies apply to what you put there). Exported backups can be encrypted with a password you choose; we never have access to that password.
Bank statement files you import (CSV, OFX/QBO) are read locally on your Mac. They are not uploaded anywhere.
The App makes a small, fixed set of network connections. Each one is listed here; there are no others.
On launch and when you choose Help → Check for Updates, the App contacts our release server (releases.shorestack.io) to compare version numbers. This request carries no personal or financial data. If an update is available, the App asks before downloading or installing anything.
When you activate the App, your license key and a machine identifier are sent to our payments provider to verify the purchase. Nothing from your books is included.
If you connect a bank feed via SimpleFIN, your Mac talks directly to the SimpleFIN bridge over HTTPS to fetch your transactions. The access credential is stored in the macOS Keychain — never in your company file or backups — and the transaction data flows only between your Mac and SimpleFIN. We are not in that path and never receive your banking data. See SimpleFIN's privacy policy for how they handle your connection.
The App keeps a local error log on your Mac so you can see (and choose to share) what went wrong. Separately, you can turn on crash reporting in Settings → Privacy. It is off by default. When on, a crash sends a small report to our error-monitoring service (Better Stack) containing only:
Before anything is sent, the report is scrubbed on your Mac: numbers and amounts, quoted text, file paths and web addresses, email addresses, and capitalized name phrases (the shape account, vendor, customer, and business names take) are removed, and error locations are rebuilt to keep only the App's own code-file names. Scrubbing is aggressive but pattern-based, which is one reason crash reporting is opt-in. The App additionally refuses to transmit any report field outside the fixed list above. Crash reports never include your books, your company file, or the local error log itself. Reports carry no account of who you are, though like any internet request they reach the service from your IP address. See Better Stack's Privacy Policy.
Help → Contact Support opens your own mail client addressed to contact@shorestack.io. Nothing is sent unless you send it, and you choose what to include.
The App can interact with these services, each described above:
Your company files and backups are on your Mac (or in folders you chose), under your control. Deleting them deletes your data — we hold no copy. To remove the App's own files, delete the App and the ~/Library/Application Support/shorestack Books/ folder. If you emailed us for support, you can ask us to delete that correspondence at any time. License purchase records are retained by our payments provider as required for tax and accounting purposes.
An earlier browser-based version of shorestack Books has been retired and is no longer available. While it operated, it offered optional account sign-in (Supabase), optional cloud sync, optional bank connections via Plaid, optional receipt scanning (OpenAI), and optional emailed reports (Resend). If you used that version, any data you chose to sync or process through those features was handled by those services under their own privacy policies, and can be deleted by emailing contact@shorestack.io — we will complete deletion within 30 days. The desktop App shares none of this: it never talks to Supabase, Plaid, OpenAI, or Resend.
The App is not intended for use by individuals under 18 years of age. We do not knowingly collect information from children.
We may update this Privacy Policy from time to time. We will post material changes on this page with a new effective date. Your continued use of the App after changes constitutes acceptance of the updated policy.
