BLZN Works is the trading brand of Blue Horizen Technology, a company in Armenia, which supplies and licenses Merchant Feed Preflight. Contact the supplier at https://blznworks.com/contact. These terms apply to purchases of Merchant Feed Preflight made through the checkout on https://blznworks.com.
The offer is one payment of USD 19 for permanent online access to the full version of Merchant Feed Preflight 1, currently 1.0.0, including later 1.x releases made available in the hosted service. It is not a subscription. Paddle calculates the final payable amount and applicable tax for your location and displays that amount before payment. The checkout amount, currency, product version and policy version form the purchase record. There is no promise of future major versions, future features or bespoke work.
Paddle acts as merchant of record for transactions processed through its checkout and provides the payment receipt and its buyer terms at https://www.paddle.com/legal/buyer-terms. BLZN Works supplies the software and product support. These product terms supplement the purchase terms and do not override Paddle's obligations or any rights that cannot lawfully be excluded.
After the server verifies the completed payment, the full version opens in the browser used for checkout, and the payer's checkout email receives a single-use sign-in link, normally valid for 15 minutes, for other browsers. Each browser sign-in lasts up to 90 days; request a new link on the checkout page at any time. No account or password is required. A payment callback, screenshot or return-page message alone does not establish a completed purchase.
The product is hosted online version 1.x of Merchant Feed Preflight at https://blznworks.com/app/merchant-feed-preflight/ in current desktop Chrome, Edge, Firefox or Safari with JavaScript and WebAssembly. The hosted tool reviews supported flat UTF-8 CSV/TSV Merchant Center feed files against rules snapshot gmc-file-rules-2026-10-21. Users confirm country, destination, feed currency and fallback category. The free demo accepts up to 50 product rows without exports; the full edition accepts up to 50,000 rows and exports a complete CSV findings report. Limits include 10 MB input, 100 columns and 100,000 findings; oversized inputs/reports are refused without truncation.
Merchant Feed Preflight checks the documented common file attributes, bounded identifier/URL/price syntax and explicit clothing/shoes conditions. Unsupported or externally dependent requirements remain Not assessed. Zero supported errors does not imply Merchant Center approval. Account/policy eligibility, website agreement, image quality/metadata, shipping/tax settings, detailed taxonomy exceptions, identifier ownership and AI-content origin are not established. No feed rewriting/upload, Merchant API/account connection, synchronization or promise to fix account/policy disapprovals is supplied.
Product support covers access, setup and reproducible defects for 30 calendar days after purchase through https://blznworks.com/contact?topic=product. No response-time guarantee or ongoing monitoring is promised. Accounting/bookkeeping advice, custom layouts/rules, third-party account configuration, regulatory advice and custom development are outside the included service. Report problems using synthetic data; do not send confidential statements/feeds, credentials or payment information.
Use only data you are authorized to process. You retain ownership of your files and generated reports. The software does not guarantee commercial outcomes, universal file/bank compatibility or future third-party format/rule changes. Supported scope and limits are stated in the guide and demo. These limits do not remove statutory conformity, repair, refund or other mandatory consumer rights or liability that cannot lawfully be excluded.
If a payment is refunded or reversed, the purchase entitlement, online access and license end. Access can be held while a pending refund, partial refund, dispute or inconsistent provider state is reviewed. Files you generated with the tool remain yours.
The policy version accepted at checkout governs that purchase. Later policy revisions do not retroactively remove accrued rights. Raise product or privacy concerns through the contact form and payment or refund concerns through the options in the receipt or https://paddle.net. Applicable mandatory consumer protections and access to competent courts remain available.

Subject to verified payment and these terms, this non-exclusive license permits one purchasing person or legal entity and its employees/contractors to use the hosted full version 1 (1.x), including client data it is authorized to process. There is no per-file/device/client usage fee. A Merchant Feed Preflight purchase does not unlock another BLZN Works product; existing SUG/IMG purchases do not unlock this product.
Access to version 1 (1.x) is permanent for the purchaser unless the purchase is refunded or the license is lawfully terminated for material breach. It does not include later major versions (2.0 and later), and it does not guarantee compatibility with future browser or document-format changes.
The purchase includes later 1.x releases made available in the hosted service. No new major version or additional product is included as an entitlement. Statutory obligations concerning the purchased software remain unaffected.
Do not resell, sublicense or share sign-in links or access outside the licensed entity, copy or redistribute the application, or present it as your own product or as a service for unrelated users without separate written permission. These restrictions do not override permissions required by law or the separate notices and licenses of included third-party components.
The application runs in your browser, so its code reaches your device. The commercial license and verified access govern authorized use; they are not a claim of tamper-proof technical protection.
