Your files never leave your device. We don't collect personal data. We don't use cookies. No accounts, no logins, no data to sell.
All watermarking happens entirely in your browser using the Canvas API and pdf-lib. Your photos and PDFs are never uploaded to any server. No server ever sees, processes, or stores your files.
This also means there is zero risk of your images being used for AI training or any other purpose. They cannot leave your device through Watermarkd.
Watermarkd stores a small amount of data in your browser's localStorage:
This data is stored only on your device and is never transmitted anywhere. You can clear it at any time through your browser settings.
We use Plausible Analytics, a privacy-friendly analytics tool that does not use cookies and does not collect personal data.
What Plausible measures:
No personal data, no image data, no fingerprinting, no cross-site tracking. See Plausible's data policy for details.
Watermarkd does not set any cookies.
The only third-party service is Plausible Analytics (described above). No other external scripts, trackers, or services are loaded.
Watermarkd is built and operated from the Netherlands, within the European Union. We follow GDPR principles by design: we minimize data collection to zero personal data and process everything locally on your device.
