CSV Splitter ("we," "our," or "us") is committed to protecting your privacy and ensuring the security of your data. This Privacy Policy explains how we handle information when you use our CSV file splitting and merging tool. We want to be completely transparent about our practices, which are designed to give you maximum control over your data while providing a powerful, free service.
CSV Splitter operates entirely within your web browser using client-side JavaScript technology. This means that when you upload a CSV file to our tool, the file never leaves your computer or device. All processing—including file parsing, splitting, merging, and randomization—happens locally in your browser's memory. We do not receive, store, or have any access to the files you process through our tool.
This client-side architecture provides several important privacy benefits. First, your sensitive contact lists and business data remain completely under your control at all times. Second, you can use our tool without creating an account, providing personal information, or agreeing to upload your data to external servers. Third, you can even use CSV Splitter offline once the page has loaded, further ensuring that your data never transmits over the internet during processing.
While we do not collect or store your CSV files or their contents, we do collect limited technical information to improve our service and understand how it's being used. This information is collected through standard web analytics tools and includes data such as your browser type, operating system, device type, screen resolution, and general geographic location (country or city level, not precise location). We also track basic usage metrics like page views, button clicks, and feature usage patterns.
This analytics data is aggregated and anonymized, meaning we cannot identify individual users or associate specific actions with particular people. We use this information solely to improve the tool's performance, identify popular features, diagnose technical issues, and make informed decisions about future development priorities. We do not sell, rent, or share this analytics data with third parties for marketing purposes.
CSV Splitter uses browser cookies and local storage to enhance your user experience. Cookies are small text files stored on your device that help us remember your preferences, such as your preferred theme (light or dark mode) and recently used settings. Local storage serves a similar purpose, allowing us to save your configuration preferences so you don't have to re-enter them each time you visit.
We use both first-party cookies (set by CSV Splitter) and third-party cookies (set by our analytics and advertising partners). First-party cookies are essential for basic functionality and cannot be disabled without affecting the tool's operation. Third-party cookies support our analytics tracking and advertising services, and you can control these through your browser settings or by using browser extensions that block tracking cookies.
You can configure your browser to refuse all cookies or to alert you when cookies are being sent. However, disabling cookies may limit some features of CSV Splitter, such as theme persistence and saved preferences. Most modern browsers provide detailed cookie management options in their settings menus, allowing you to make informed choices about which cookies to accept.
CSV Splitter integrates with certain third-party services to provide analytics and advertising functionality. We use Google Analytics to understand how visitors use our site, which pages are most popular, and how users navigate through the tool. We also use Google AdSense to display advertisements that help support the free operation of our service. These third-party services may collect information about your browsing activity across different websites over time.
Google Analytics collects information such as how often users visit our site, what pages they visit, and what other sites they used prior to coming to our site. We use this information to improve our service and understand user behavior patterns. Google AdSense uses cookies to serve ads based on your prior visits to our website and other websites on the internet. You can opt out of personalized advertising by visiting Google's Ads Settings or by visiting the Network Advertising Initiative opt-out page.
These third-party services have their own privacy policies that govern how they collect and use information. We encourage you to review Google's Privacy Policy and Google's AdSense Privacy Policy to understand their practices. We do not control these third parties' tracking technologies or how they may be used, and we are not responsible for their privacy practices.
Because CSV Splitter processes all files locally in your browser without uploading them to our servers, the primary security responsibility lies with you and your device. We recommend using CSV Splitter only on secure, trusted devices and networks. Ensure your operating system and browser are up to date with the latest security patches, and use antivirus software to protect against malware that could compromise your device's security.
Our website itself is served over HTTPS, which encrypts the connection between your browser and our servers. This prevents third parties from intercepting or tampering with the web page as it loads. However, once the page is loaded and you begin processing files, all operations occur locally on your device without any network communication related to your file data.
We implement industry-standard security measures to protect our website infrastructure from unauthorized access, use, or disclosure. However, no method of transmission over the internet or electronic storage is completely secure. While we strive to use commercially acceptable means to protect your information, we cannot guarantee absolute security.
CSV Splitter is not directed to children under the age of 13, and we do not knowingly collect personal information from children. Our service is designed for business professionals, email marketers, and data analysts who are typically adults. If you are a parent or guardian and believe that your child has provided us with personal information, please contact us so we can take appropriate action to remove such information from our systems.
CSV Splitter is accessible from anywhere in the world, and our website infrastructure may be hosted in various countries. If you access our service from outside the United States, please be aware that information we collect (such as analytics data) may be transferred to, stored, and processed in the United States or other countries where our service providers operate. These countries may have data protection laws that differ from those in your country of residence.
By using CSV Splitter, you consent to the transfer of your information to countries outside your country of residence, which may have different data protection rules than your country. However, we take steps to ensure that your information receives an adequate level of protection in the jurisdictions in which we process it, consistent with applicable data protection laws.
Depending on your location, you may have certain rights regarding your personal information under applicable data protection laws. These rights may include the right to access the personal information we hold about you, the right to request correction of inaccurate information, the right to request deletion of your information, and the right to object to or restrict certain processing activities.
Since CSV Splitter does not collect or store your CSV files or their contents, and since we collect only minimal analytics data that is aggregated and anonymized, there is typically no personal information for us to access, correct, or delete. However, you can control cookies and local storage through your browser settings, and you can opt out of personalized advertising through the mechanisms described in the Third-Party Services section above.
If you are located in the European Economic Area (EEA), you have additional rights under the General Data Protection Regulation (GDPR), including the right to lodge a complaint with a supervisory authority. If you are located in California, you have rights under the California Consumer Privacy Act (CCPA), including the right to know what personal information is collected and the right to opt out of the sale of personal information. We do not sell personal information as defined by the CCPA.
We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or other factors. When we make changes, we will update the "Last updated" date at the top of this policy. If we make material changes that significantly affect your privacy rights, we will provide prominent notice on our website before the changes take effect.
We encourage you to review this Privacy Policy periodically to stay informed about how we are protecting your information. Your continued use of CSV Splitter after we post changes to this Privacy Policy constitutes your acceptance of those changes. If you do not agree with any changes to this policy, you should discontinue use of our service.
If you have questions, concerns, or requests regarding this Privacy Policy or our privacy practices, you can reach us through the contact information provided on our website. We will make reasonable efforts to respond to your inquiry in a timely manner and to address any concerns you may have about how we handle your information.
We are committed to complying with applicable privacy and data protection laws, including but not limited to the GDPR, CCPA, and other relevant regulations. Our client-side processing architecture is designed to minimize data collection and maximize user privacy, which helps us maintain compliance with these stringent requirements. We regularly review our practices to ensure ongoing compliance as laws and regulations evolve.
We may disclose information if required to do so by law or in the good faith belief that such action is necessary to comply with legal obligations, protect and defend our rights or property, prevent fraud or abuse, or protect the personal safety of our users or the public. However, given that we do not collect or store your CSV files or their contents, there is typically no user data for us to disclose in response to legal requests.
