Privacy Policy
Last updated: April 2026
This website does not collect, store, or transmit any personal data.
Documents you process
Documents processed by PermaDrop and SupraDrop remain entirely in your browser's local memory. They are never uploaded to any server. When you close the tab, all document data is discarded.
Analytics and tracking
No analytics. No tracking pixels. No third-party scripts that observe
your behavior. This site uses no cookies except one: a localStorage
entry that stores your dark/light mode preference.
External communication
The only external communication initiated from these tools is from your browser directly to the perma.cc API, using your own API key. This communication occurs only when you explicitly choose to archive a URL. No intermediary server is involved.
Open source
All tools are open source under the AGPL v3 license. The source code is publicly available on GitHub. You can verify exactly what runs in your browser.
