Who we are and what this policy covers

This Privacy Policy describes how FreeLocalConverter ("we", "us", or "our") handles information when you visit https://freelocalconverter.com/ (the "Service") and use our pages, tools, and related features.

This policy applies whether you browse informational pages, run utilities in your browser, or interact with site controls. If you use a third-party deployment, mirror, or fork of this project, another party may operate hosting and analytics. In that case, their privacy notices may apply instead of or in addition to this policy.

What the Service is

FreeLocalConverter provides free, web-based utilities such as viewers and converters for data, documents, images, video, and developer workflows, together with informational content. Functionality may change over time as tools are added, updated, or retired.

Unless a specific tool page clearly states otherwise, many features are implemented to perform processing in your web browser on your device. That design goal does not guarantee that no information is transmitted when you load or use the site.

Local processing in your browser

Where a tool is designed for local processing, files you select, text you paste, and similar inputs may not leave your device for that operation. The code running in your browser performs the work. We do not receive the contents of those files on our servers solely because you opened them in such a tool.

Local processing does not remove ordinary risks on your device (for example shared devices, unlocked screens, or malware). You are responsible for securing your hardware, browser, and operating system.

Some tools may store preferences, draft inputs, or recent selections using your browser storage (such as localStorage or sessionStorage). That data remains on your device unless you clear it or your browser profile syncs it across devices.

Information we may collect or observe

Even when individual tools process data locally, operating a public website commonly involves collecting or generating limited technical and usage information. Depending on how this deployment is configured, examples may include:

- Network and device technical data, such as IP address, approximate location derived from IP, browser type and version, device type, operating system, referrer URL, pages viewed, timestamps, and diagnostic logs used for security and reliability.

- Information you voluntarily submit through site features, such as a contact or feedback form, including the content of your message, your email address if you provide one, and related metadata needed to deliver or respond.

- Records needed to meet legal obligations, respond to lawful requests, or protect the rights, safety, and integrity of users and the Service.

Cookies, analytics, and similar technologies

We and our service providers may use cookies, pixels, local storage, and similar technologies for purposes such as remembering preferences, measuring traffic and performance, debugging errors, preventing fraud or abuse, and (if enabled on this deployment) displaying or measuring advertising.

Where required by law, we will seek consent before using non-essential cookies or similar technologies, consistent with any cookie banner or preference tool presented on the site.

Third-party services and links

We may rely on vendors for hosting, content delivery, analytics, security, email delivery, advertising, error reporting, and similar functions. Those vendors may process limited information under their own terms and privacy policies.

The Service may link to external sites, repositories, or resources. We do not control third-party practices, and this policy does not apply there.

Legal bases (EEA, UK, Switzerland, and similar regions)

If you are in the European Economic Area, the United Kingdom, Switzerland, or another jurisdiction with similar rules, we process personal data only where we have a valid legal basis. Depending on the activity, bases may include: performance of a contract or steps you request; our legitimate interests that are not overridden by your rights (such as securing the Service, understanding aggregate usage, and improving reliability); compliance with law; or your consent where required (for example certain analytics or marketing technologies).

Your privacy rights and choices

Depending on where you live, you may have rights to access, correct, delete, port, or restrict processing of personal information, or to object to certain processing. You may also have the right to withdraw consent where processing is consent-based.

You can manage many browser controls yourself, including cookies, storage, and site permissions. You may also use industry opt-out tools where available for advertising or analytics, subject to provider support.

To exercise rights related to information we control, contact us using any contact method published on the Service. We may need to verify your request as permitted by law. You may also lodge a complaint with your local supervisory authority.

Retention

We retain information only for as long as needed for the purposes described in this policy, unless a longer period is required or permitted by law. Technical logs may be kept for a limited period for security and operations. Aggregated or de-identified data may be retained longer where it no longer identifies you.

Security

We implement reasonable administrative, technical, and organizational safeguards designed to protect information we process. No method of transmission over the Internet or electronic storage is completely secure, so we cannot guarantee absolute security.

Children

The Service is not directed to children under 13 (or the minimum age required in your jurisdiction to consent to data processing without parental permission). We do not knowingly collect personal information from children. If you believe a child provided personal information, contact us using published contact details so we can take appropriate steps.

International visitors

We may process information in countries other than where you live. Those countries may have data protection laws that differ from your own. Where required, we use appropriate safeguards for international transfers.

Changes to this Privacy Policy

We may update this policy to reflect changes to practices, features, legal requirements, or clarifications. When we do, we will revise the "Last updated" date at the top of this page. If changes are material, we will provide additional notice as appropriate (for example a banner on the site).

Important notice

This policy is provided for transparency. It is not legal advice. If you run your own copy or deployment of this software for others, you are independently responsible for your privacy disclosures, contracts, vendor relationships, and compliance with applicable law.
