Privacy Policy

Last updated: March 26, 2026

LearnQL is a small product, so this policy is short. We collect only what we need to run the service, and we don't sell your data or run ads.

What we collect

  • Account info — your name and email address when you sign up
  • Usage data — your exercise attempts, progress, and query submissions so we can show you your history and improve the product
  • Payment info — handled entirely by Stripe; we never see or store your card details

How we use it

  • To run LearnQL and give you access to your account
  • To show you your progress and exercise history
  • To improve the product (aggregate, anonymized patterns — not individual surveillance)
  • To contact you about your account or major product changes

We don't use your data for advertising, and we don't sell it. Ever.

These services only receive what they need to do their job. We use PostHog to understand how the product is used (e.g. which exercises are completed). No ad networks or tracking pixels.

Data retention

We keep your data as long as your account is active. If you delete your account, we'll remove your personal data within 30 days. Some anonymized usage data (not tied to you) may be retained to improve the product.

Your rights

You can:

  • Access the data we have on you
  • Correct anything that's wrong
  • Delete your account and associated data
  • Export your data

Just email us at contactus@learnql.com and we'll take care of it. If you're in the EU or California, you also have additional rights under GDPR and CCPA respectively — same process, just email us.

Cookies

We use session cookies to keep you logged in. That's it — no tracking cookies, no third-party ad cookies.

Changes to this policy

If we make significant changes, we'll notify you by email. Minor updates will be reflected in the "last updated" date above.
