Forge collects the minimum data needed to provide the service:
Your data is used to provide personalised learning experiences, track your progress, and improve the platform. We do not sell your personal data to third parties. We do not use your data for advertising, and we do not run advertising or social media tracking pixels on this site.
We record which drills people finish and where they get stuck, so we can fix the parts that don't teach. Nothing is recorded until you agree to it in the banner shown on your first visit, and you can change your mind at any time in Settings → Data & privacy. If your browser sends a Do Not Track signal we treat that as a decline, whatever the banner says.
These events are behavioural, not content: we store that you completed a drill and what you scored, never the text you wrote in it.
When you complete AI-evaluated exercises, your prompts are sent to Anthropic's Claude API for scoring and feedback. Anthropic does not use API inputs to train models (per their API data policy). Prompts are retained only in your learning history.
We use a small number of service providers. Each one only receives what it needs to do its job:
Your account data is kept for as long as your account exists, so your progress and history stay available to you. Delete your account and it goes with it — see below.
Server logs and error reports are kept for 30 days. Analytics events are kept for 12 months. Waitlist entries are kept until you ask to be removed or your cohort opens and you create an account.
Two of these you can exercise yourself, immediately, without asking us. In Settings → Data & privacy you can:
For correction, restriction, objection, or anything else, email hello@forge-learn.app. We will respond within 30 days.
We use two, and neither is for advertising:
If you agree to analytics, PostHog may set an identifier to distinguish one visitor from another. There are no advertising cookies, no cross-site trackers, and no third-party pixels.
You must be at least 16 years old to use Forge.
We will notify you of material changes via email at least 30 days before they take effect.
For privacy questions, contact us at hello@forge-learn.app.
We use one cookie to keep you signed in — that one isn't optional. Separately, we'd like to record which drills people finish and where they get stuck, so we can fix the parts that don't teach. No ad networks, no selling anything on. Privacy policy.
