Your files, your device.
The short version: the in-browser tools never upload your PDF, and the API processes files transiently and never trains on them.
The browser tools
Every converter on this site — PDF to JSON, Markdown, CSV and Text — parses your file entirely in your browser using its text layer. The PDF never leaves your device. There's nothing for us to upload, store, or delete, because the file is never sent anywhere.
The API
The API necessarily receives the files you send it, because that's how it runs OCR on scans, detects tables, and extracts bank statements. Those files are processed transiently to produce your response and are not used to train any model. Retention is kept to what's needed to run and debug the service; if you're handling sensitive documents, get in touch and we'll confirm the current retention window for your account.
Accounts and billing
If you create an account we store your email and an API key (as a hash, never the raw key) to authenticate your requests and meter usage. Payments are handled by Stripe; we don't see or store your card details.
Analytics
We use privacy-respecting, aggregate analytics to understand which pages are useful. We don't sell your data, and we don't build advertising profiles.
