ENCODE Toolkit Last updated: March 2026
The ENCODE Toolkit is a local software tool that runs entirely on your machine. It is designed with privacy as a core principle.
We collect no data. The ENCODE Toolkit:
- Has no telemetry
- Has no analytics
- Has no tracking
- Has no user accounts on our side
- Sends no data to the developer or any third party
- Does not phone home for any reason
The Software makes network connections only to the following endpoint:
https://www.encodeproject.org— the ENCODE Project REST API, operated by Stanford University
These connections are made solely to fulfill your search, metadata, and download requests. All connections use HTTPS with certificate verification enforced.
No other external connections are made. The Software does not contact any analytics services, advertising networks, or third-party APIs.
All data created by the Software is stored locally on your machine:
- Tracked experiments — stored in a local SQLite database in your home directory (
~/.encode-toolkit/tracker.db) - Downloaded files — saved to directories you specify
- Credentials (if provided) — encrypted using your operating system's keyring (macOS Keychain, Linux Secret Service, Windows Credential Locker) or a local encrypted file with restricted permissions
No data is stored remotely. No data is shared with the developer or any third party.
When you search or download data, your queries are sent to the ENCODE Project API at encodeproject.org. The ENCODE Project is operated by Stanford University and is funded by the National Human Genome Research Institute (NHGRI). Their data use policies apply to data retrieved from their API. See: https://www.encodeproject.org/help/data-use-policy/
If you provide ENCODE API credentials (for accessing restricted/unreleased data), they are:
- Stored in your OS keyring (preferred) or encrypted locally with Fernet symmetric encryption
- Never transmitted to anyone other than
encodeproject.org - Never logged or written to plaintext files
- Clearable at any time via the
encode_manage_credentialstool
The Software does not knowingly collect any personal information from anyone, including children under 13.
If this privacy policy changes, the updated policy will be included in the Software distribution. Since the Software collects no data, meaningful privacy changes are unlikely.
