Privacy Policy
1. Overview
ScryCheck is a free Commander deck analysis tool. We believe in minimal data collection. This policy describes what information we collect, why, and how it is used. We do not sell your data.
2. Information we collect
Deck lists and analysis results
When you submit a deck for analysis, the deck list and computed results (power level, vector scores, combo data, etc.) are stored in our database. Submitted analyses may appear publicly in the deck directory. We do not associate deck submissions with individual identities unless you voluntarily include identifying information in the deck name or description.
Local storage (“My Decks”)
If you use the “My Decks” feature, a lightweight record of recently analyzed decks is stored in your browser's localStorage. This data never leaves your device and is not transmitted to our servers.
Contact form submissions
If you submit a message via the contact form, we collect your name, email address, and message content in order to respond to your inquiry. This information is transmitted via Resend and retained only as long as necessary to address your request.
Analytics
We use Google Analytics to understand aggregate usage patterns (pages visited, session duration, general geography). Google Analytics may set cookies on your device. No personally identifiable information is transmitted to us through analytics. You can opt out using the Google Analytics opt-out browser add-on.
3. How we use your information
- To provide and display deck analysis results
- To populate the public deck directory with aggregate community data
- To respond to contact form inquiries
- To improve the Service by understanding how it is used (via aggregate analytics)
We do not use your information for advertising, profiling, or sale to third parties.
4. Third-party services
Scryfall
Card data and pricing are fetched from the Scryfall API. Requests to Scryfall are server-side; your IP address is not shared with Scryfall.
Resend
Contact form submissions are delivered via Resend, an email delivery service. Your name and email are processed by Resend solely to deliver your message.
Google Analytics
Aggregate usage data is collected by Google Analytics. See Google's Privacy Policy for details on how they handle this data.
Neon (PostgreSQL)
Deck analyses are stored in a PostgreSQL database hosted by Neon. Data is stored in the United States.
5. Cookies
ScryCheck itself does not set cookies beyond what is required for the Service to function. Your theme preference (light/dark) is stored in localStorage, not cookies. Google Analytics may set its own cookies independently.
6. Data retention
Deck analyses are retained indefinitely as part of the public deck directory. Contact form messages are retained only as long as needed to address your inquiry. Local storage data is retained until cleared by you in your browser settings.
7. Your rights
You may clear your local “My Decks” history at any time through your browser settings. If you would like to request deletion of a specific deck analysis from the public directory, please reach out via our contact page.
