Terms

Last updated: November 6, 2026

This page is a summary. Each product has its own terms of use, linked below, and those terms are the ones that apply to the product.

In short

Our products are provided by Arkpine Software. Free versions and their features may change over time; each product's terms say how.
Pro is sold through Lemon Squeezy, our reseller, whose terms apply to the purchase, including refunds. Most Pro purchases are a single payment. SlotKeeper's yearly key and Steady Translate's 30-day and yearly keys are also single payments and do not renew automatically.
You are responsible for the files and content you open, translate or collect with our products, and for having the right to use them. Keep your own copies of anything important.
The products are provided "as is", without warranties of any kind. To the extent the law allows, Arkpine Software is not liable for any loss arising from their use.
