Terms of Use

• You sign in with Google or Apple. Keep that account secure; you are responsible for activity on your account.
• Give a display name that isn't offensive or misleading. We may change or remove names that break these terms.
• You can sign out of other devices from the app, and delete your account at any time.

• Each app is free to start. Premium unlocks the rest of that app's course, the final exam and certificate, offline access and no ads.
• Premium is sold as monthly or yearly subscriptions or a one-time lifetime purchase, through the App Store or Google Play. Prices are shown in the store before you buy.
• A purchase unlocks Premium in the app you bought it in, not in other apps.
• Subscriptions renew automatically until you cancel them in your store account. A free trial converts to a paid subscription unless you cancel before it ends.
• Refunds are handled by Apple or Google under their policies.

A certificate confirms that the named account passed the course's final exam on the date shown. It is not an academic degree or a professional accreditation. We may revoke a certificate obtained by cheating, for example by sharing answers or using several accounts.

Please don't:

• copy, resell or republish course content, questions or answers;
• use bots, scripts or multiple accounts to gain XP, leaderboard places or certificates;
• try to access other people's accounts or data, or to break or overload the apps, API or website;
• reverse engineer the apps except where the law allows it.

We may suspend accounts that break these rules.

Courses, posts, fixes, images and the TechStack Atlas name belong to TechStack Atlas or its licensors. You may read them for your own learning and share links to them. Code samples in posts and fixes may be used in your own projects.

We work hard to keep lessons and fixes correct, but technology changes fast. Content is provided “as is”: check important steps against official documentation, and back up your work before applying a fix.

To the extent the law allows, TechStack Atlas is not liable for indirect or consequential losses arising from using the apps, the website or the content. Nothing in these terms limits rights you have under consumer law that can't be excluded.

We may update these terms as the apps change. If a change matters, we'll update the date above and tell you in the app. Using the apps after a change means you accept the new terms.
