Privacy policy

Last updated: 2026-09-21

Progresspedia is a community-edited learning platform. This page describes what we collect, why, and what we do with it. Plain English, no tricks.

What we collect

• Account info: email address and username when you sign up. Optional: avatar, display name, social links you add to your profile.
• Activity: courses you enrol in, articles you mark complete, votes you cast, comments and edits you submit. This is the platform.
• Notification preferences: whether you've opted into product emails. If you use the mobile app and allow notifications, a device token so we can send them.
• Technical data: server logs (IP, user agent, request path) for security and debugging. Errors are sent to PostHog so we can fix bugs.
• Product analytics: page views, clicks and form submissions, collected with PostHog and stored in the EU. If you're signed in, this is tied to your account so we can see how a learner moves through a course. PostHog may also record a session (what's on screen as you click around); anything you type is masked. No cross-site tracking, no advertising IDs.

What we don't collect

• We don't sell data. We don't share it with advertisers.
• We don't use third-party advertising or cross-site tracking. Analytics is first-party and only about how you use Progresspedia.
• We don't ask for more than the platform needs to work.

How we use it

• Run the platform: show you your progress, your contributions, your dashboard.
• Public contributions: comments, votes, and suggested edits are tied to your username and visible to other users. That's how a community wiki works.
• Email you: magic-code logins, replies to your contributions, and account notices. If you haven't visited in a while we may send an occasional "what's new" email. You can turn off everything except logins and account notices in your settings.
• Improve the site: aggregate analytics tell us which articles are read; error reports tell us what's broken.

Who we share it with

Only the service providers we need to operate the site:

• Railway: hosting and database.
• Resend: sending transactional email.
• PostHog: product analytics and error tracking, hosted in the EU.
• Cloudflare: serves the site from its network and runs the bot check on sign-up and edit forms.
• Apple and Google: deliver push notifications to the mobile app, if you've allowed them.

Each is bound by their own privacy terms; we don't authorise them to use your data for anything beyond running the service.

Your rights

• Access: your profile page shows your data; email us for a full export.
• Correction: edit your profile, or email us.
• Deletion: delete your account from your settings page, or email [email protected] if you'd rather we do it for you. Public contributions (edits accepted into articles) may stay since they're now part of the article history, but we'll detach your identity from them.

Cookies

We use a session cookie to keep you logged in, a CSRF token cookie to protect form submissions, a small cookie that remembers which look of the site your browser was given while we test a new design, and PostHog's cookies for the analytics described above. No advertising cookies.

Children

Progresspedia isn't directed at children under 13. If you believe we've collected data from a child under 13, email us and we'll delete it.

Changes

If this policy changes materially, we'll email registered users. The "last updated" date at the top reflects the current version.
