## What is CosmosLock?

Feed your curiosity, not your feed.

Every time you reach for social media, CosmosLock steps in with something fascinating. Instead of mindless scrolling, you learn — discovering a science fact, answering a quiz question, or sitting with a mind-expanding idea. From quantum physics to deep space, evolution to neuroscience, replace your scroll habit with discovery.

WHAT YOU GET:
- Lock any app behind science learning — choose Instagram, TikTok, Twitter, Reddit, YouTube, or any app
- Multiple unlock methods — fact reading, fill-in-the-blank, word challenges, and timed reflection
- Topic-based selection — choose your interests or let CosmosLock surprise you
- Smart scheduling — lock apps all day, study hours, evenings, or custom periods
- Progress tracking — see how many facts you've learned instead of hours scrolled
- Family-friendly — uses Apple Screen Time to enforce locks reliably

FREE + PREMIUM:
CosmosLock requires a Premium subscription for app access. Eligible subscriptions start with Apple's 1-week introductory free trial and unlock unlimited app unlocks, unlimited schedules, advanced challenge types, and the full premium science library.

SCIENCE CONTENT:
CosmosLock includes a curated library of over 2,100 science facts, explanations, and quiz questions:
- Astronomy & Space — black holes, exoplanets, the Big Bang, cosmic phenomena
- Physics — quantum mechanics, relativity, electromagnetism, thermodynamics
- Biology & Life Sciences — evolution, genetics, neuroscience, ecology
- Chemistry — elements, reactions, molecular structures, materials science
- Earth Science — geology, climate, plate tectonics, volcanoes, oceans
- Mathematics — beautiful proofs, paradoxes, and number theory

Content ranges from accessible fun facts to deeper explanations, organized by difficulty so you're always learning at the right level.

DIFFICULTY LEVELS:
- Beginner: Bite-sized facts anyone can enjoy
- Intermediate: Deeper explanations with context
- Advanced: College-level concepts and connections
- Scholar: Research-level insights and cutting-edge discoveries

HOW IT WORKS:
1. Choose which apps to lock (social media, games, news — anything)
2. Set your schedule (all day, study breaks, or custom)
3. When you open a locked app, CosmosLock presents a science fact or quiz
4. Learn, think, and unlock — replacing empty scrolling with real knowledge

PRIVACY FIRST:
CosmosLock processes everything on your device. No learning data, no quiz scores, and no personal information ever leaves your phone. We use Apple's built-in Screen Time framework — no tracking, no ads, no accounts required.
