Everything runs in your browser. Nothing is sent to our servers. Nothing is stored. Completely safe and secure.
All AlvaiTools (image resizer, document converter, slug generator, handwriting tool, image-to-PDF, etc.) run entirely in your browser. Your files, text, and data never leave your device. We do not upload, receive, or process your content on any server.
We do not store your files, inputs, or outputs. No copies are kept on our systems. Once you close the tab or leave the page, nothing remains on our side. Zero data retention.
Your data is processed only in your browser's memory. We use standard web technologies (JavaScript) that run locally. There is no backend pipeline that handles your content — making it completely safe and secure by design.
We believe in full transparency. This policy clearly states: we do not collect, store, or transmit your tool usage data. We may use minimal analytics (e.g. page views) that do not identify you or your content. We do not sell data — we have no data to sell.
