How We Handle Your Data
Technical details on our AI Mentor document publishing system, cosmological IDs, client fingerprints, and your rights over the data you generate.
Version 1.0.0 — March 2026
Core Data Principles
Minimal by Default
We collect only what is necessary to operate the service. No advertising, no profiling, no sale of data.
Transparent by Design
Every data handling decision is documented here and in our open-source code. You can verify our claims.
User-Controlled
Documents you publish are owned by you. You can delete them at any time via our public API.
Publicly Auditable
Published documents go to docs.platphormnews.com — a public, searchable knowledge base. You choose what gets published.
Open Source
The fingerprinting and ID generation logic is open source. No hidden behaviour.
Right to Delete
Any document you published can be deleted immediately via the DELETE API endpoint with your session token.
AI Mentor Document Publishing
When you interact with the AI Polymath Mentor and choose to share a conversation, the system generates a document and publishes it to docs.platphormnews.com via its public API. Documents are only published when you explicitly click "Share this conversation" — they are never published automatically.
Each published document receives two identifiers: a cosmological ID and a client fingerprint association. These are described in detail below.
Cosmological IDs (ULID)
Every published document receives a Universally Unique Lexicographically Sortable Identifier (ULID). This is a 26-character string like 01ARZ3NDEKTSV4RRFFQ69G5FAVthat encodes both a timestamp and random bits.
We call these "cosmological" because like the cosmos itself, they are:
- —Effectively unique across all space and time — the probability of collision is astronomically small
- —Temporally ordered — documents can be sorted by creation time without a database query
- —Opaque — the ID reveals nothing about the document's content or the user who created it
- —Portable — the same ID works across all services in the Platphorm News Network
Client Fingerprints
A client fingerprint is a short hash derived from non-personally-identifying browser signals: screen resolution class, timezone offset bucket, language group, and a session-specific random salt. The salt changes each browser session, making the fingerprint non-persistent and non-trackable across sessions.
The fingerprint serves one purpose: allowing you to claim, edit, or delete documents you published in the current browser session. It is stored only in your browser's sessionStorage and is never transmitted except as part of a document publish or delete request.
We do not use fingerprints for cross-site tracking, advertising, or identity resolution. The hashing algorithm (SHA-256 with per-session salt) makes reverse-engineering impossible.
Document Lifecycle
Conversation occurs
You chat with the AI Mentor. Nothing is stored server-side during this phase.
You choose to share
You click 'Share this conversation'. The client generates a ULID and fingerprint hash.
Document is published
A POST request is sent to docs.platphormnews.com/api/v1/documents with your conversation formatted as Markdown, the ULID as the document ID, and the fingerprint as a claim token.
Document is live
The document appears at docs.platphormnews.com/docs/[ulid] and is immediately accessible via the public API.
You can delete it
Using your session's fingerprint token, you can DELETE the document at any time via DELETE /api/v1/documents/[ulid]. The document is permanently removed.
