Terms of use
SyntaxShelf is free to use for personal reference, with an optional paid Premium upgrade.
Reference content
The cheat-sheet content is provided for quick recall and learning. Code examples are original and intended as concise references — always test code in your own environment before relying on it in production.
Premium
The core reference — every cheat sheet, all section pages, search, and one-tap copy — is free. An optional Premium upgrade adds personal notes and unlimited favorites. Purchases are processed by RevenueCat and Stripe; subscriptions renew automatically and can be cancelled anytime from the link in your receipt email. See Privacy for how payment data is handled.
No warranty
SyntaxShelf is offered without warranty of any kind. While we aim for accuracy, we make no guarantee that every example is free of errors or up to date with the latest language or tool version.
Your data
Any content you create (notes, favorites) is stored only on your device. You are responsible for backing it up via the export feature in Settings if you want to keep it.
Acceptable use
Use SyntaxShelf for lawful reference purposes. Do not attempt to misuse or redistribute the bundled content as your own product.
