What is stored

Five tables and one option: Plus the cartpresets_settings option, and meta on order line items. See Order line item meta.

​
The one row with personal data in it

A redemption records who claimed a preset, so a per-customer cap can be enforced. For a signed-in customer that’s their user ID. For a guest it’s their billing email address, lowercased, since that’s the only stable way to recognise the same guest twice. No IP address is recorded. A developer can change how customers are identified with cartpresets_redemption_customer_key. Without it there can be no per-customer limit. You can’t know somebody has already claimed something if you don’t record that they did. A customer can ask for that record, and ask for it to be forgotten: see Privacy and personal data.

​
What leaves your site

On the free version, nothing does. There’s no analytics, no phone-home, and no scripts or styles enqueued on your storefront. On CartPresets for WooCommerce Pro, one thing does: a licence check. Your licence key and site URL go to the licensing service to activate, to verify periodically, and to check for updates. The update check sends the key in a request header, never in the address. It runs from wp-admin and cron only, never from your storefront, so a customer browsing your shop never triggers it. The Presets report reads your own WooCommerce order tables. Those figures never leave your site.
The Copy system report button on the Settings sidebar reads your install and puts the result on your clipboard. It sends nothing. It’s there so you can paste it into a support thread yourself.

​
Uninstalling

Deleting the plugin removes nothing by default. That’s the opposite of most plugins, and it’s deliberate. If you deactivate to test something, or delete and reinstall to fix a bad upload, you shouldn’t lose a year of work to a routine action. Each category has its own checkbox under Settings → Data management → Delete on uninstall. They’re there on both versions, and saved with Save changes:
These run when you delete the plugin, not when you deactivate it, and they can’t be undone. Ticking one does nothing straight away. It sets up the deletion for the next time you delete the plugin.

​
What is never removed

Order line item meta stays, whatever you switch on. It’s part of your order history, and an order that recorded which preset it came from should keep that record after the plugin is gone. The carrier product is also left alone unless you opt in for it specifically. It’s a WooCommerce product that may be attached to old orders, and deleting it would damage your order history.

​
GDPR and data requests

The only personal data is the redemption record: a user ID or billing email against an order ID. WordPress’s own tools handle it. Tools → Export Personal Data returns every preset an address claimed. Tools → Erase Personal Data anonymises those claims rather than deleting them, so a spent purchase limit stays spent. For the full detail, including why erasure keeps the row, see Privacy and personal data.

​
Moving to a new site

Presets are database rows, so a full database migration carries them. If you’re moving between separate stores, use Import and export instead: Export presets and Import presets, under Settings → Data management → Preset data. It matches products by SKU on the way in, which a raw table copy can’t do, and every imported preset arrives inactive. On the free version both buttons are locked.
