How we handle data

Almost none. When you open a tool, your browser reports the tool name so we can count total usage; your IP address is only one-way hashed to prevent automated submissions and is deleted automatically after about 1 hour. Feedback is sent only when you tick consent and press Send.

No. The PDFs, images and videos you open stay in your browser tab and are processed right on your device. We never receive your files. When you close the tab, the files are gone from the browser; results exist only when you download them.

Some upcoming tools need large or constantly updated data, such as construction prices or zoning, so they have to look things up on a server. Their cards say so clearly so you know in advance. All the tools available now process data on your device.

Data you save in the tools (Family Calendar, notes, CV drafts, flashcards) lives on your device: delete it inside the tool, or clear site data in your browser settings. To delete feedback you've sent, email contact@lpc.vn with the receipt code.

No. We don't sell data or share it for advertising. The only exception is the Speech to text tool, which uses the browser's own speech recognition, so the audio goes to the browser provider (for example, Google for Chrome), not through our servers.

After the first visit with a connection, your browser caches the site and the tools' code, so they usually still open when your connection is spotty. Heavy parts such as text recognition or video processing are downloaded on first use, so try them once while you're online.
