# SheetSentry

> SheetSentry is an automation result checker. It watches the Google Sheet that an automation (n8n, Zapier, Make, or custom scripts) fills, and alerts you when rows are missing, empty, or late. Status: pre-launch, waitlist open. "SheetSentry" is a working name.

Website: https://sheetsentry.app/

## The problem
Automations can report "success" for days while writing zero rows (expired token, empty upstream response, renamed column). Heartbeat monitors only prove a job ran; SheetSentry checks what actually landed in the destination sheet.

## How it works
1. Publish one tab as CSV (File → Share → Publish to web → CSV) and paste the link. SheetSentry only downloads that CSV and never changes your sheet or accesses your Google account.
2. Choose the timestamp column, the columns that must be filled, and the deadline.
3. Get alerted if rows are missing, empty, or late.

## Pricing (early pricing, monthly, USD)
- Starter: $29/mo for 3 monitored reports
- Business: $79/mo for 15 monitored reports
- Agency: $199/mo for 50 monitored reports
Paid plans and a free pilot (up to 3 monitors per email, no account) open soon; join the waitlist at https://sheetsentry.app/#waitlist to be notified

## FAQ
- What data can you access? Only the CSV of the tab you publish to the web. We download it read-only every 15 minutes; we never get access to your Google account. Note: a published CSV link can be read by anyone who has it.
- Will you ever edit my sheet? No. SheetSentry never edits, adds, or deletes anything in your sheet.
- What about days with no data on purpose? You can mark quiet days (weekends, holidays) as allowed so they don't trigger alerts.
- Which tools does it work with? Any tool that writes to Google Sheets: n8n, Zapier, Make, custom scripts.
