Promptlyr is designed with a "Local First" architecture. We believe your prompts and creative ideas belong to you.
All your history and preferences are stored directly in your browser using IndexedDB. No data is ever sent to a cloud database or external server for storage.
To prevent casual inspection of your data, we encrypt your history entries using the Web Crypto API (AES-GCM) before saving them to IndexedDB.
We do not use cookie banners because we do not use tracking cookies. The app is stateless from our server's perspective.
The code is open source. You can audit the storage and encryption logic yourself on our GitHub repository.
Since data is stored in your browser, clearing your browser cache/data for this site will permanently delete your history. You can export your data (coming soon) if you need to transfer it.
