Software operator and contact
Dmytro Slisarenko, an individual in Ukraine, develops and operates the software. Perunlight is a brand name, not an incorporated company. Paddle is the merchant of record and authorised reseller at checkout. Contact: mitcaslis@gmail.com.
Products and prices
The paid downloads have one-time prices in USD on each listing. Applicable taxes and the total are shown at checkout. Guides and example data are free to read. Complete programs are supplied in the paid download where stated on the product page. Existing copies retain their included permissions. There are no subscriptions or preorders.
Payment and delivery
Paddle handles checkout as reseller. The checkout page gives you a private recovery code before payment. After Paddle confirms payment, our checkout page makes the purchased ZIP available. Keep the code; lost-code support requires verified ownership. We do not promise email delivery. Checkout is open for one-time purchases.
Use and support
Read the stated tested scope before purchase and review generated outputs. The license explains permitted use; third-party rights remain in force. No future updates or support response time are promised. Mandatory rights remain intact.
SvarogCut online access
A valid SvarogCut purchase also unlocks the hosted online studio with the same private recovery code: up to 200 parts, 50 part types and 200 stored plans within seven days, with a maximum of eight new plans per minute. Free access provides five successful plans of up to ten parts and five types, including exports. Editing, invalid plans and downloading an existing plan do not use a free calculation. Additional short-term service limits can apply. Save project JSON and exports on your device; the service is not a permanent archive. Online availability is not guaranteed indefinitely and does not change the perpetual local-use license for the purchased offline version. The online and offline editions have different features and project formats; see the guide. There is no recurring charge.
SvarogLoad online access
A confirmed SvarogLoad purchase also opens the hosted loading planner with the same private recovery code: up to 30 cargo types, 200 pieces per plan, 200 stored plans within seven days and eight new plans per minute. Free access provides five successful plans of up to five types and 20 pieces, including CSV, PNG and browser-print exports. Editing, invalid or entirely unplaceable loads and exporting an existing plan do not spend a free plan. Additional short-term service limits can apply. Save the project and exports yourself. Online availability is not guaranteed indefinitely; the purchased offline version keeps its perpetual local-use license. There is no recurring charge. See the online guide.
