Privacy policy

Who we are

Mindtrix is a daily microlearning app about Life Intelligence: understanding yourself, other people, and the world around you. In this policy, “we” and “us” mean the team that operates Mindtrix, and “you” means the person using it.

This policy explains what we collect when you use the app or the website, why we collect it, and the choices you have.

What we collect

• Account details: your email address, and your name and profile picture if you sign in with Google or Apple. Your password is handled by our authentication provider and never stored by us in readable form.
• Your learning activity: the cards you view, your quiz answers and scores, your streak, the topics you follow, the cards you like, and your recap, puzzle and battle results.
• Subscription details: whether your Plus plan is active, which plan you chose, and the Stripe customer and subscription identifiers. Your card number never reaches us - it stays with Stripe.
• Reminders: the email address we use to send streak reminders.
• Basic usage information: which features you use, so we can tell what is working and fix what is not.

How we use what we collect

• To build your daily session, keep your streak, and show you your own progress.
• To unlock the Plus features you have paid for and keep your subscription status correct.
• To personalise your feed and adjust difficulty (Plus features).
• To send the reminder emails you have signed up for.
• To understand which parts of the app are used and which are not, and to fix problems.

AI-generated content

Cards, quizzes, puzzles and explanations are written with the help of AI models. To generate them we send topic and subject context, not your personal details, email address or account information.

Ads and analytics

Plus is ad-free. The free version may show ads supplied by Google. Where ads are shown, Google may use cookies or device identifiers to select them, under Google's own policies.

We also record simple product events (for example, that a session was completed). These events are not tied to advertising profiles and are not sold.

Who we share data with

We do not sell your personal data. We share it only with the service providers that make Mindtrix work: our hosting and database provider, our authentication provider, Stripe for subscription billing and payments, Google for sign-in and (on the free plan) ads, and the AI providers that generate learning content.

We may also disclose information if the law requires it.

How long we keep it

We keep your learning data for as long as your account exists. Billing records are kept by Stripe for the period the law requires, even after your account is deleted.

Your choices and your rights

• Delete your account and your data at any time from About > Account & data > Delete my account. This removes your profile, your progress, your likes and your battle history.
• If you have an active Plus subscription, deleting your account stops it from renewing, so you are not billed again.
• Streak reminders stop as soon as your account is deleted.
• If you want a copy of the data we hold about you, or want something corrected, our support details are on the app's store listing.

Children

Mindtrix is not directed at children under 13, and we do not knowingly collect personal information from them.

Changes to this policy

If we make a meaningful change to this policy we will show it in the app. Continuing to use Mindtrix after a change means you accept the updated policy.

Contact

If you have a question about this policy, or want to exercise any of the rights above, email support@themindtrix.com and we will respond as quickly as we can.
