Ahay.app ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we handle your information when you use our Smart PDF Merge Tool (the "Service"). Our core principle is privacy by design, and our Service is built to be 100% local.
Our Service operates entirely within your web browser on your local device. We do not collect, store, or have access to any of the following:
Since no files are ever uploaded to our servers, your data remains completely private and under your control at all times.
All processing, including merging, layout adjustments, and rendering, is performed by your computer's CPU/GPU using JavaScript libraries that run locally. Once you close the browser tab, all processed data is discarded.
The Service uses browser `localStorage` for the sole purpose of saving your preferred settings, such as layout choices, orientation, and language. This information is stored on your device and is not transmitted to us. We do not use tracking cookies or any third-party analytics services that would compromise your privacy.
The Service utilizes well-known open-source libraries like `pdf.js` and `pdf-lib`, which are loaded into your browser to perform the PDF manipulation. These libraries also operate locally and do not transmit your data.
We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page. You are advised to review this Privacy Policy periodically for any changes.
If you have any questions about this Privacy Policy, you can contact us by visiting the contact page on our website.
