Privacy Policy
Last updated: 20 October 2026
Overview
MockRows is a free, browser-based mock data generator. You build a schema on a pastel spreadsheet; row generation and CSV/JSON export run on your device. This policy explains what happens when you use the published MockRows origin (and any future domain for the same product).
In short: generation runs locally in your browser. We do not operate a cloud upload API for your schemas or rows, we do not require accounts, and we do not show ads.
What we process — and what we don’t
We do not receive the schemas or generated rows you create. Field typing, seeding, preview, CSV/JSON download, Sample schemas, Clear, and privacy-receipt downloads run in your browser. Dataset bytes are not uploaded to MockRows servers as part of the tool flow.
We do not ask you to create an account. We do not collect names, email addresses, or payment details through this product — there is no checkout and no paid plan.
We do not sell personal data. We do not use advertising networks on this site.
Local processing
Fake values are produced with a vendored @faker-js/faker build served from the same origin. Optional preferences — such as language (mockrows-lang-v1) — may be stored in your browser’s localStorage so they persist between visits on that same browser and device. You can clear them by clearing site data.
Hosting and network logs
The site is a static site hosted on Cloudflare Pages. Like most websites, requesting pages, scripts, styles, and public assets may create standard edge or access logs at the hosting/CDN layer (for example IP address, user agent, URL path, and timestamps). Those logs are used for operating and securing delivery of the site.
We do not use hosting logs to inspect or reconstruct the content of datasets you generate, because those files are not sent to us for processing.
Cookies and local storage
MockRows does not rely on third-party advertising cookies. We may use browser localStorage for preferences described above. If Cloudflare or the browser itself sets strictly technical cookies for delivery or security, that is outside the generator and is not used by us to track your mock data.
Analytics
We do not run third-party analytics (such as Google Analytics or Plausible) on this site at the time of this update. If that ever changes, we will update this policy before enabling it.
Third-party scripts
Processing runs with browser APIs and same-origin scripts bundled with the site (including the vendored faker build), not loaded from unrelated third-party ad or tracker domains for the core tool.
Synthetic data
Generated values are synthetic. Do not treat them as real identities. Do not use MockRows to impersonate people or commit fraud. Because processing is local, outputs stay on your device — but they may still be visible to anyone who can see your screen or device backups.
Children
MockRows is a general-purpose utility. We do not knowingly collect personal information from children. Because processing is local and we do not require accounts, we do not solicit such information through the product.
International users
The product UI defaults to English. A Chinese language option is available only when you choose it. Selecting a language stores a preference locally; it does not create an account profile on our servers. We do not label dates with regional timezone city names in the UI.
Changes
We may update this policy as the product or hosting setup changes. The “Last updated” date at the top will change when we do. Continued use of the site after an update means you accept the revised policy.
Optional feedback form. If you use the floating Feedback button, we store the email address you enter, your message, which MockRows site you came from, the page URL, a basic browser user-agent string, and the time of submission in our database so we can read and respond. Tool file processing still runs locally in your browser and is separate from this form. 中文：若你使用右下角「反馈」按钮，我们会保存你填写的邮箱、反馈内容、来源站点、页面地址、浏览器信息和提交时间，便于回复；工具本身的文件处理仍在本地完成。
