Privacy Policy
Last updated: June 21, 2026
1. Privacy-first by design
PDF Toolkit is built so your files stay yours. The PDF utility tools run entirely in your browser, which means your documents are processed on your device and are never uploaded to, stored on, or seen by our servers.
2. Information we do not collect
We do not collect, transmit, or retain the contents of any file you open with the utility tools. Merging, splitting, editing, converting, compressing, and securing all happen locally.
3. Data stored in your browser
If you enter an AI provider API key, it is stored only in your browser’s local storage on your own device so you don’t have to re-enter it. It is never sent to us. You can remove it at any time by clearing the field or your browser storage.
4. AI features (bring your own key)
When you use the AI chat or AI tools, your selected document and your prompt are sent directly from your browser to the AI provider you choose (Anthropic, OpenAI, or Google) using your own API key. That data is handled under the chosen provider’s privacy policy. We act only as a pass-through and do not retain a copy.
5. Cookies and analytics
We do not use advertising cookies or sell any data. Only the minimal local storage described above (such as your theme preference and API key) is used to make the app work.
6. Security
Because processing is local, the most sensitive data never leaves your machine. For the AI features, traffic to providers is sent over encrypted (HTTPS) connections. No system is perfectly secure, so please use the tools on documents and devices you trust.
7. Children's privacy
The Service is not directed to children under 13, and we do not knowingly collect personal information from them.
8. Changes to this policy
We may update this Privacy Policy from time to time. Any changes will be reflected by updating the “Last updated” date below.
