CSV INTEGRITY LAB
Privacy Policy
Updated 5 November 2026 · Applies to this website and the CSV Integrity Lab web preview.
Developer and contact
CSV Integrity Lab is developed under the gnouden brand. For privacy questions or requests, contact [email protected]. Developer information: gnouden.com.
Your CSV stays on your device
The web preview decodes, parses and inspects files in a browser worker and creates XLSX downloads locally. Source file contents and the generated workbook are not uploaded to our application server or sent to an AI service. No account is needed. The built-in sample is fictional.
Working rows are held in browser memory. Clear file or closing the tab discards that working copy. The app does not intentionally store source data in cookies, browser storage or a server database. Downloaded XLSX files remain on your device and are subject to your browser, operating system and backup settings.
Website delivery and technical data
Opening this site makes ordinary web requests for the pages, scripts and styles. Our hosting and Cloudflare process connection information such as IP address, request time, browser/request headers and requested URL to deliver and protect the website. Project Nginx access logging is disabled; operational/error logs may still contain technical request details. Provider-level processing is subject to the provider’s policies. Do not place CSV data or other secrets in a URL.
The site has no advertising or behavioral analytics integration and does not intentionally set app tracking cookies. Infrastructure providers may use security-related mechanisms. No CSV-content telemetry is collected.
Support email
If you email us, we receive your email address and the message and attachments you choose to send. We use these to answer and troubleshoot your request. Email providers process the correspondence. Please send only a minimal fictional or redacted example; do not send sensitive source files, passwords, full license keys or card details.
Support correspondence is retained as needed to resolve requests, maintain relevant correspondence and satisfy applicable obligations. You may request access, correction or deletion using the support address. We assess requests and explain any records that must be retained. This is not a promise of immediate deletion from all provider backups.
Payments and licenses
No checkout or live license service is currently enabled, so this site does not currently collect payment details or order information. If commercial sales are enabled after approval, we plan to use Lemon Squeezy for checkout, receipts and license delivery. At that point the applicable payment, order, license and retention information will be provided before purchase, and this policy will be updated. We do not currently claim to operate those live flows.
Sharing, changes and requests
We do not sell CSV contents or support correspondence. Technical hosting and email providers process data needed to provide their services. Necessary disclosure may occur to comply with applicable obligations or protect the service. We update this page when practices change; the date above identifies this version. Contact [email protected] with privacy questions.
