Data and privacy

What it reads

From WooCommerce:

• Order line items: product ID, variation ID, quantity, order date, order status.
• Product data: SKU, name, stock quantity, stock management flag, cost price if set.

That is the whole list. SimplifyStock does not read customer records, billing or shipping addresses, email addresses, payment details, or order notes.

What it stores

Its own tables, alongside WooCommerce’s:

Table	Contents
simplifystock_demand	Daily demand per product
simplifystock_forecast	Current forecast and confidence per product
simplifystock_suppliers	Supplier records and lead times
simplifystock_po	Purchase orders and receipts
simplifystock_log	Sync and forecast run history

All of it lives in your database. Uninstalling removes these tables if you tick Delete data on uninstall; the default is to leave them, so a reinstall does not lose your history.

Hosted forecasting

Off by default. On the free plan it is unavailable; on Pro it is opt-in per site.

When enabled, what is transmitted is the daily demand series — product identifier, date, quantity — and your configuration. What is not transmitted: customer data of any kind, order IDs, prices, product names, or SKUs. The product identifier is a per-site hash, so the same product on two sites is not correlatable.

Models are per store. Your data is never pooled into a shared model and is not used to train anything that another customer benefits from. Turning hosted forecasting off deletes the series within 30 days.

GDPR

SimplifyStock processes no personal data, so it does not appear in WooCommerce’s personal data exporter or eraser — there is nothing for it to export or erase.

If you enable hosted forecasting, SimplifyBase is a processor for the demand series described above. A data processing agreement is available on request.

Data retention

Data	Default retention	Configurable
Demand history	Indefinite	Yes
Forecast snapshots	90 days	Yes
Sync and error logs	30 days	Yes
Purchase orders	Indefinite	No — records of purchases

Removing everything

wp simplifystock uninstall --delete-data

Drops every table and deletes all options. Irreversible, and it will ask you to confirm.
