Privacy Policy — Castahedron
Last updated: 2026-06-17
Castahedron is a browser extension that simulates rolling dice. This policy covers both the extension and purchases made on this storefront.
The extension collects nothing
The Castahedron extension collects, transmits, stores, and shares no personal data. Specifically:
- No analytics or tracking of any kind
- No crash reporting sent to external servers
- No identifiers (device, user, or session) collected
- No network requests are made by the extension at any time
Local storage only
The extension saves your dice configuration (which dice are selected, quantity
of each, the modifier value) and which premium features you've unlocked, locally
in your browser via chrome.storage.local. This data:
- Never leaves your device
- Is not accessible to any server or third party
- Can be cleared at any time by uninstalling the extension or clearing extension storage
License keys for premium unlocks are verified on your device using built-in cryptography — activating a key sends no data anywhere.
Permissions
The extension requests only:
- storage — to save your dice configuration and unlocked features between sessions (local only).
- tabs — to find and focus an already-open Castahedron arena tab instead of opening duplicates. It is used only to locate the extension's own tab; it does not read your browsing history or the content of any page.
No permission is used to access browsing history, page content, or any other browser data.
Purchases on this website
Premium unlocks are not yet on sale, and this website currently takes no payments and loads no checkout or payment scripts.
When unlocks do go on sale, checkout will be handled by Lemon Squeezy as Merchant of Record. Lemon Squeezy will process your payment and email address to complete the sale, prevent fraud, and send your license key and receipt. We will receive your email and order details to provide support; we will not receive or store your card details. See Lemon Squeezy's privacy policy at lemonsqueezy.com/privacy. This section will be updated, and the "Last updated" date changed, before any payment is accepted.
We do not sell your data or use it for advertising.
Third parties
The extension does not integrate with any third-party services, APIs, or advertising networks. This website loads no third-party scripts, analytics, or advertising. If payments go live, processing on this website will be handled solely by Lemon Squeezy as described above.
Changes
If this policy is updated, the "Last updated" date above will change.
