1. What We Use
Lurnly does not use traditional cookies. Instead, we use localStorage — a browser and app technology that stores data locally on your device.
2. What We Store in localStorage
We store the following data locally on your device:
| Key | Purpose |
|---|---|
| lurnly_album_art | Cached album artwork to avoid repeated API calls |
| lurnly_chord_cache | Cached chord fingerings fetched from AI |
| lurnly_coach_chat_{song} | AI Coach conversation history per song |
| lurnly_coach_daily_{date} | Daily AI Coach question counter |
| lurnly_has_visited | Whether you have seen the onboarding screen |
| lurnly_song_{key} | Improved song data cached locally |
3. Why We Use localStorage
- To improve app performance by avoiding repeated network requests
- To save your conversation history with AI Coach
- To track daily usage limits
- All data is stored locally on your device only
4. We Do Not Use
- Tracking cookies
- Advertising cookies
- Third-party analytics cookies
- Google Analytics
5. How to Clear Your Data
You can clear all locally stored data by:
- Going to your browser/app settings and clearing site data
- Deleting and reinstalling the app
6. Third-Party Services
Our third-party providers (Supabase, Stripe, Anthropic) may use their own cookies or storage technologies. Please refer to their respective privacy policies for details.
7. Changes
