## What is Factolin?

Factolin is a "medicine capsule"-themed facts app that drops an interesting fact on your phone throughout the day. Not dry encyclopedia entries — short, context-rich, human-sounding facts that actually stick.

   WHY FACTOLIN?

• Short, striking facts — 80% are under 180 characters, with the surprise landing in the first sentence
• A playful "side effect" line for each fact — the pharma-label tone that gives the app its personality
• Every fact links to relevant Wikipedia articles — one tap away when you want to dive deeper
• 8 categories: General Culture (geography, animals, plants, climate, word origins, everyday objects), Science, History, Tech, Economy, Sports, Art, Philosophy
• General Culture is always pinned — every other dose comes from General Culture, the alternate slot from your chosen categories
• You choose how often you want a fact (every 4/6/8/12/24 hours)
• Save your favorites, browse your history, revisit anytime
• Native Turkish and English content — not machine-translated

  HOW IT WORKS

1. Quick 4-step onboarding: language, age group, interests, notification frequency
2. Open the app — your first fact is already there
3. Tap "Next Dose" for a fresh one anytime
4. Silent push notifications keep dosing you at your chosen cadence
5. General Culture is on by default — designed to make the world feel more interesting than yesterday

 SAFE FOR AGES 12 AND UP

No sexual content, profanity, murder or torture detail, or graphic violence. Historical events are covered in a news / academic tone. Parents can relax.

  ABOUT THE CONTENT

Facts are generated with Google's Gemini AI but never blindly shipped:
• Every fact goes through an editorial approval pipeline
• Dates, names, and events are cross-checked
• Clichéd facts (Einstein E=mc², Google founded in 1998, etc.) are actively filtered out
• Facts about the same person or event are automatically de-duplicated
• Result: lesser-known, verifiable facts that make people say "wait, really?"

  GENERAL CULTURE — THE HEART OF THE APP

The strange borders of world geography, unexpected animal behaviors, how plants communicate through fungal networks, turning points in climate history, word origins, invention stories of everyday objects — life is broad, and so is the range of what we cover.

  PRIVACY

No sign-up required — the app runs anonymously on your device. Data like your age range and language preference stays on your device and is used only to personalize what you see. Ad serving follows child-directed policies (COPPA, GDPR-K) for younger users.

A daily vitamin for a curious mind. It's dose time.
