How ShadowDNS handles your data.

Factual answers to the questions DNS, networking, and homelab users ask before uploading a log.

How your data is handled

  1. 01

    Select a file

    Your DNS export is read locally by your browser. The raw file is never sent to ShadowDNS servers.

  2. 02

    Local parsing

    Parsing and analysis run in your browser. Only the resulting report data is sent to ShadowDNS.

  3. 03

    Report generated

    The generated report is stored so it can be viewed through its unique link.

  4. 04

    View by link

    Reports are accessed through a unique, non-guessable URL until they expire.

Raw DNS exports are processed locally in your browser and are not stored server-side. DNS data is not sold, shared, or used to train AI models.

Key fact

Additional information

What happens when I select a file?
The file is parsed and analyzed in your browser. Only the resulting report data is sent to ShadowDNS so it can be viewed through its unique link.
How are reports protected?
Reports use unique identifiers with cryptographically generated access tokens. They cannot be accessed through predictable URLs and require possession of the report link.
Can I request report deletion?
Yes. Email hello@shadowdns.org and the associated report will be removed.
