This Privacy Policy explains how LetKnowledge (“we”, “us”) handles information on tools.letknowledge.com (the “Site”).
The JSON, Base64 and URL tools run entirely in your web browser. The text you paste is processed on your own device and is not sent to our servers. We do not store, sell or share it.
The Site saves one setting, your light or dark mode choice, in your browser’s local storage. This stays on your device and you can clear it at any time from your browser settings.
Our hosting provider (Namecheap) may keep standard server log data such as IP address, browser type, pages visited and time of access. This is used for security, troubleshooting and keeping the Site running.
At the time of writing, the Site does not set tracking cookies and does not use analytics. If we add analytics or advertising (for example Google AdSense or Google Analytics) in the future, we will update this policy first and, where required by law, ask for your consent.
The Site may link to other websites. We are not responsible for their privacy practices. Please read their policies.
The Site is not directed at children under 13, and we do not knowingly collect personal information from children.
We use HTTPS to protect data sent between your browser and the Site. No online tool can guarantee complete security, so please do not paste real passwords, private keys, or sensitive personal data into any online tool.
Depending on where you live, you may have rights to access, correct or delete personal data we hold about you. Since we hold little or no personal data, most requests can be handled by contacting us directly.
We may update this policy from time to time. The “Last updated” date above shows when it last changed.
