Privacy Policy

This Privacy Policy explains what information 4K Photo Converter ("we", "us", "our") collects when you use 4kphotoconverter.com (the "Website"), and how it is used. The short version: your photos never leave your device, and we don't ask you for any personal information.

1. Your photos

All image upscaling and enlarging happens locally in your web browser, using your device's processor and GPU. When you select, drop or paste an image:

• The image is read directly by your browser and is not uploaded to our servers or to any third party.
• We do not see, store, copy, analyse or share your images or the upscaled results.
• Images exist only in your browser's memory and are discarded when you close or reload the page.

You can verify this yourself by opening your browser's developer tools and watching the network tab while you upscale a photo.

2. Information we collect

We do not require an account, and we do not ask for your name, email address or any other personal details to use the tool. The Website does not use advertising trackers.

If you allow it, we use Google Analytics to understand how visitors use the Website, such as which pages are visited, how long visits last, the type of device and browser used, the approximate location (country or city) and how visitors found the Website. Google Analytics collects this information using cookies and similar technologies, and it is processed by Google. We use it only in aggregate to improve the Website. Google Analytics never receives your photos or the upscaled results. Google Analytics is off by default: it only loads after you choose "Accept" in the cookie banner, and you can change your choice at any time with the "Cookie settings" link at the bottom of every page. You can learn more inhow Google uses information from sites that use its services, and you can opt out with theGoogle Analytics opt-out browser add-on.

Like almost every website, the servers that host the Website may automatically record standard technical information when your browser requests a page — such as your IP address, browser type, the page requested and the date and time of the request. These logs are used only to keep the Website secure and working properly, and are kept for a limited period by our hosting provider.

3. Cookies and local storage

If you accept analytics, Google Analytics sets cookies (such as _ga and _ga_*) to tell visits apart and to measure how the Website is used, as described above. If you decline, these cookies are not set, and choosing "Decline" later through "Cookie settings" removes them. These cookies do not identify you by name, and we do not use cookies for advertising. Your choice itself is saved in your browser's local storage so we don't ask again on every visit. You can block or delete cookies at any time in your browser settings, and the upscaler will still work.

Your browser may also cache the Website's files and the AI model so the tool loads faster on your next visit. This data stays on your device, and you can clear it at any time from your browser settings.

4. If you contact us

If you email us, we will receive your email address and whatever you choose to include in your message. We use this only to reply to you and to improve the Website, and we do not sell or share it with third parties.

5. Third-party links

The Website links to external sites such as open-source project pages. We are not responsible for the privacy practices of those sites, and we encourage you to read their privacy policies.

6. Children's privacy

The Website is not directed at children under 13, and we do not knowingly collect personal information from children.

7. Your rights

Depending on where you live, you may have the right to access, correct or delete personal information we hold about you. Because we collect so little, in most cases the only personal information we could have is an email you sent us. To make a request, contact us at the address below.

8. Changes to this policy

We may update this Privacy Policy from time to time. When we do, we will change the "Last updated" date at the top of this page. Continuing to use the Website after changes are posted means you accept the updated policy.
