Privacy Policy

Klarrity respects your privacy. This policy explains what data we collect, how we use it, and your rights regarding your information.

• Text you highlight: Processed to generate flashcards, then discarded after generation.
• Account information: Email address for authentication and subscription management.
• Usage data: Basic analytics to improve the service (no personal content stored).

• Generate flashcards from your selected text
• Process payments and manage subscriptions
• Send important service updates (no marketing)
• Improve and maintain the service

We use industry-standard encryption and security practices to protect your data. Your highlighted text is processed in real-time and is not permanently stored on our servers.

We use trusted third-party services for specific functions:

• Stripe: Payment processing
• Supabase: Authentication and database
• Anthropic: Flashcard generation (Claude)

• Crash and performance reports: If the app crashes or hangs, it sends a short technical report to fix the problem. It is not linked to you.
• YouTube: When you make cards from a YouTube video, the app asks YouTube for the video's captions directly, sending only the video's ID. YouTube sees your device's IP address, as with any visit.
• Lecture recordings: When you record a lecture or bring in a recording, the audio stays on your iPhone. It is never uploaded and is left out of iCloud backup. Speech is turned into text on your iPhone. If you tap Make cards, the lecture's title and text are sent to our server, which uses Anthropic's Claude to write the cards, then discards the text. We don't store it or write it to our logs. Our logs record only counts and timings, such as how long the text was and how many cards were made, and we keep a daily count of lectures made, for the weekly limit. Anthropic doesn't use the text to train its models and deletes it within 30 days, unless it must keep it longer to enforce its usage policy or by law.
• Friend streaks: If you pair with a friend, the name you choose and your lock streak are stored in Apple's iCloud (CloudKit) under your iCloud account, where your friend's app can read them. Nothing else is shared. Tap Stop sharing, or Settings, then Delete my friend-streak data, to delete them at once. If a friend's record isn't updated for 45 days, the pair ends.
• iCloud backup: If you turn on backup, your decks sync through your own private iCloud account. We can't see them.
• Purchases: Subscriptions are handled by Apple. We never see your payment details.

You can request to access, correct, or delete your personal data at any time. Contact us and we'll respond within 30 days.
