Privacy Policy — Zero-Server Data Guarantee

        The Core Local CSV Privacy Guarantee: We do not operate remote file ingestion servers. When you use any tool on Local CSV, your data never leaves your device’s browser sandbox.
      

1. Information We Do Not Collect

Unlike cloud-based conversion platforms, Local CSV executes all parsing, cleaning, merging, splitting, and reformatting on your computer or mobile device using client-side JavaScript and Web Workers.

No File Uploads: Your CSV, TSV, JSON, or Excel files are read into local RAM via the HTML5 File API. No file binary or text stream is sent to an external server.
No Database Storage: We do not operate databases storing user records, customer datasets, or row contents.
No Account Information: Local CSV is completely free and requires zero login, email registration, or API authentication.

2. Information We Collect Automatically

To maintain website performance, prevent denial-of-service attempts, and serve contextual advertising, our static hosting providers and ad partners may collect standard telemetry:

Server Log Data: Basic HTTP request headers (IP address, user-agent, referring URL, and timestamp) collected by content delivery networks (CDNs).
Local Storage: We store a single key named lc-theme in your browser’s localStorage solely to remember your light/dark mode preference.

3. Third-Party Advertising & Analytics Disclosures

Local CSV is supported by privacy-conscious programmatic display advertising. Third-party advertising vendors may deploy cookies or web beacons to display ads based on previous visits to this or other websites. These ad networks do not have access to any spreadsheet data you load into the tool.

4. GDPR & CCPA Compliance by Design

Under the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA), Local CSV operates under the principle of Privacy by Design and by Default. Because personal data contained within spreadsheets is never transmitted, stored, or processed on our servers, there is no risk of data breach or unauthorized third-party disclosure on our infrastructure.

5. Ecosystem & Governance

Local CSV is part of the LMSTools.cloud family of local-first browser utilities. For questions or technical security inquiries, contact us via our Support Page.

Frequently Asked Privacy Questions

Does Local CSV see or store my uploaded files?

No. Local CSV operates purely as a client-side web application. All calculations, parsing, and exports happen in your browser's local memory. No spreadsheet content is ever transmitted to or stored on any server.

What data is stored in my browser's local storage?

We store a single preference key ('lc-theme') in your browser's localStorage to remember whether you selected dark or light mode. We do not store spreadsheet rows, file names, or personal identifiers.

Is Local CSV compliant with GDPR and CCPA regulations?

Yes. Because Local CSV does not collect, process, transmit, or monetize any personal data contained within your spreadsheets, it inherently complies with GDPR, CCPA, and global privacy frameworks by design.
