What we collect
The iPhone app collects no personal data and does not upload your PDF content to us or to third-party servers. The website uses self-hosted Plausible to count page views, App Store link clicks, and successful browser tool runs.
On-device processing
The iPhone app requests no network access. Files you import and compressed results are stored locally on your device unless you choose to export or share them.
Browser tools
The free browser tools at /tools/ process files entirely in your browser. Nothing is uploaded, no document content is sent to any server, and tool analytics include only the tool id and page locale.
Payments
Purchases are processed by Apple through the App Store. We do not receive your payment card details.
