Calculator data

The free calculator runs in your browser. Job inputs are stored locally on your device so they can be restored on your next visit. The current version does not send calculator inputs to a server.

Support messages

If you contact StitchMargin through the checkout provider, the message and purchase details are used to answer your request and provide the service you asked for. Support messages are not sold or added to unrelated marketing lists.

Purchases

A checkout provider may process payments and delivery for paid products. Its privacy terms apply to information entered on its checkout page. StitchMargin receives the purchase details needed for delivery and customer support.

Analytics

Privacy-friendly traffic analytics may be added to measure page visits and calculator use. This policy will be updated before analytics are enabled.

Data control

You can clear saved calculator values by clearing this site's browser storage. Purchase-related data requests can be sent through the support channel in the checkout receipt.
