Seller and contact
Seller: Aliaksei Chareshneu, OSVČ, IČO 23041625. Registered business address: Čenětická 2413/1a, 149 00 Praha 4, Czech Republic (public Czech contract register, 16 October 2026). Order assistance and complaints: chereshnev.biochem@gmail.com. This is not a payment or donation to Družina Moravy z. s. Seller confirms OSVČ neplátce DPH (not a Czech VAT payer) as of 8 November 2026; Czech VAT is not charged in these listed prices. Cross-border digital sales may become subject to additional VAT/OSS duties at statutory thresholds, which the seller must monitor.
What a purchase includes
A single non-transferable internal-use license for the specific version of the ZIP file described on the product page. It is a self-service digital product, not a lesson, live service, managed software subscription, professional consulting or access to AI credits. File format: standard ZIP with HTML/JS or Python/text files as described. You must have compatible hardware and software listed on each product page. Personal use or internal use within one purchasing legal entity is permitted; public redistribution and resale are not.
Price and checkout
Current catalog prices: Scientific CSV Rescue Kit 490 Kč and AI Workflow ROI Toolkit 690 Kč (CZK). Purchases use secure Stripe Checkout only after active consent to the published terms and immediate delivery request. The actual final amount, applicable tax treatment, seller and delivery details must be visible at checkout before any order is submitted. No automatic renewal or added service is included.
Delivery after payment
At checkout the customer actively requests immediate digital supply. After payment is confirmed by a signed Stripe server notification, the buyer is returned to a download page. A verified payment session authorizes a time-limited ZIP download; unverified or refunded orders are denied. If Stripe redirects before notification is processed, the page checks for confirmation and allows a retry. If delivery does not work, email the seller with your Stripe receipt; do not share card details.
14-day right of withdrawal
We do not ask buyers to waive the statutory withdrawal right in this first release. A consumer may request cancellation within 14 days of the digital-content contract by emailing the seller, including after immediate digital access. Any mandatory statutory rights, rights for defective digital content, remedies and statutory refund deadlines remain unaffected. Do not publish your Stripe session URL. Sample request: "I withdraw from my digital content purchase made on [date], for [product]. Please confirm the refund." We will ask only for information needed to identify the order. For Czech consumer guidance see Czech Trade Inspection Authority (ČOI).
Privacy and cookies
The public catalogue does not use tracking pixels, analytics cookies, hidden messages or marketing forms. Clicking checkout sends only your chosen product and your explicit terms/delivery acknowledgement to the shop's existing EU-region Supabase instance; it generates a random reference. Stripe processes payment and buyer details under its own checkout terms. The backend retains a minimal technical record of the payment session, consent reference, price, fulfillment and any refund/dispute state, not your card data or marketing profile. It is separate from association participant data and not used for unsolicited marketing. Technical receipts are retained only as long as reasonably required for order, consumer, security, accounting and legal obligations; requests about personal data may be sent by email.
Support and complaints
For a faulty file or interrupted download, email chereshnev.biochem@gmail.com. Nothing on this page limits mandatory consumer protections. Individual consulting and customization are optional, separate paid engagements and never added automatically.
