原文外掛簡介
Clockdo helps WordPress site owners protect their publish date by generating a verifiable content timestamp.
Clockdo creates a deterministic fingerprint (SHA-256) and requests an OpenTimestamps proof. Public posts use the public proof flow. Draft and private versions use a private, hash-only protocol and never send the title, author, URL, WordPress post ID, or post body. When full-text archive mode is enabled, every meaningful save in draft, pending, scheduled, private, or published state is first stored as an immutable local snapshot.
Features
Generate per-post timestamp records
Request OpenTimestamps proof
Export .ots and manifest files
Automatic draft, publish, update, and opt-in private-post workflows
Separate article coverage and immutable proof-history views
Immutable full-text snapshots for every meaningful save when full-text archive mode is enabled
Snapshot validation, idempotent requests, and recoverable asynchronous retries
Optional public meta tags and post footer with verification link
Independent verification using standard tools
Use Cases
Prove when an article was first published
Add a visible publication record to your posts
Protect against plagiarism disputes
Maintain an independent timestamp history
Provide verification material for disputes or takedown cases
English (Summary)
* Generate per-post records and proof history in the dashboard.
* Save proof artifacts to your WordPress uploads folder.
* Optionally inject public meta tags and/or a “Verify” footer link.
* Proofs are designed to be independently verifiable with standard OpenTimestamps tools.
Privacy
This plugin may process and store locally:
* WordPress post metadata (post ID, URL, timestamps),
* immutable full-text snapshots containing post title, body, excerpt, slug, author ID, status, and audit timestamps when full-text archive mode is enabled,
* deterministic hashes (SHA-256),
* proof IDs/statuses,
* proof artifacts written to local disk under wp-content/uploads/clockdo-ots-private/.
Outbound requests:
* This plugin connects to a remote timestamping API (configured by you) to request proofs.
* Full-text archive v3 submissions upload only a manifest commitment; the exact snapshot and post body remain in the local WordPress database. Public manifests may include already-public identity fields such as URL, title, author, and timestamps.
* Legacy export workflows may upload export.json, including post content when the operator explicitly enables that older combination of settings.
* Private and draft submissions upload a hash-only manifest. They do not upload the title, author, URL, WordPress post ID, or post body.
* A SHA-256 commitment is an integrity fingerprint, not encryption. It reveals when two committed snapshots are equal, and low-entropy content may be guessable by testing candidate text.
Public disclosure:
* If you enable meta injection or public verify links, your public pages may expose a hash/canonicalization identifier and a verification link.

Third Party Services
This plugin connects to the following external services:
Clockdo Timestamping API (ots-api.clockdo.com)
Used to register sites, submit timestamp requests, and check proof status.
Endpoints called: /api/v1/public/sites, /api/v1/public/site-stamps, /api/v1/site/me, /api/v1/proofs/{proof_id}, and authenticated manifest/OTS artifact paths.
Data sent for registration: site domain.
Data sent for public proofs: post URL, SHA-256 hash, and manifest/export JSON according to settings.
Data sent for private/draft proofs: Site ID, SHA-256 content commitment, event/visibility/source-status fields, canonicalization version, and idempotency key. The per-site secret authenticates the request.
Service homepage: https://ots.clockdo.com
Privacy policy: https://ots.clockdo.com/privacy
Terms of service: https://ots.clockdo.com/terms
Clockdo Verification Page (ots-verify.clockdo.com)
If public verify links are enabled, post pages may link to this domain for independent proof verification.
All outbound connections are made via the WordPress HTTP API (wp_remote_post / wp_remote_get).
The API Base URL is configurable; the above domains are defaults.

Uninstall
Ordinary uninstall removes plugin settings, transient queue state, legacy batch tables, and mutable display metadata. It deliberately retains the immutable ots_post_snapshots and ots_post_proofs audit tables, including any full-text snapshots, and it may leave proof files under wp-content/uploads/clockdo-ots-private/.
For irreversible full deletion, first make and verify a backup, then follow assets/docs/data_deletion_uninstall.md to remove the two retained tables and the private uploads directory explicitly.
Disclaimer
This plugin provides timestamping and verification tooling. It is not legal advice, not a certification service, and does not determine ownership.
