Frequently Asked Questions

Everything you need to know about 5head and how it can help you remember everything

What is 5head and who is it for?
5head is a knowledge management system designed for language learners, developers, and networkers. It combines spaced repetition flashcards, note-taking, and a smart CRM in one app. Perfect for anyone who wants to remember everything that matters.
How does the spaced repetition work?
5head uses the SM-2 algorithm (same as Anki) to optimize your flashcard review schedule. Cards you struggle with appear more frequently, while cards you know well appear less often. This helps you retain information long-term with minimal effort.
Can I import my Anki decks?
Import/export functionality is coming soon! We're working on making it easy to migrate your existing flashcard decks from Anki and other platforms.
What happens after I use my 100 free flashcards?
You can upgrade to Pro for unlimited cards, or stay on the free tier and focus on your most important cards. The free tier is designed to be generous enough for most users to get started.
Is my data private?
Absolutely. Your notes, flashcards, and connections are yours. We'll never sell your data or show ads. AI features are optional and can be turned off completely. Read our privacy policy for more details.
What if I break my streak?
Pro members get 2 streak freezes per month to protect their progress. Free members can recover streaks within 72 hours, or upgrade to Pro for automatic protection.
