Who We Are
Card Signal is a search, catalog, and collector research site. Contact: cardsignalapp@gmail.com.
Information We Collect
Card Signal collects information you provide, such as an account email, saved collection records, card details, prices, notes, newsletter signups, and alert requests. Our hosting and security providers may also receive ordinary technical records needed to deliver and protect the site. Affiliate networks may receive click information when you choose an affiliate link.
How We Use Information
- To send requested updates
- To improve the site and price-finder experience
- To understand which pages and tools are useful
- To track affiliate link performance
- To understand traffic sources and improve page layout, search quality, and guide topics
- To review and prioritize alert requests
- To respond to questions sent to cardsignalapp@gmail.com
Analytics and Site Improvement
Optional analytics tools remain off unless they are configured and you choose to allow them. If enabled, they may process pages viewed, interactions, device and browser details, approximate location, and referral information. You can reopen Privacy Choices from the site footer. Declining optional analytics does not block Card Signal's core features.
Accounts and Collection Data
Account and collection information is stored with service providers used to operate Card Signal. Collection records are tied to the signed-in account, and database access rules are designed so users can access only their own records. Do not store highly sensitive personal information in card notes.
Affiliate Links
Card Signal may use affiliate links. If you click an affiliate link and make a qualifying purchase, Card Signal may earn a commission. Affiliate networks may collect information according to their own policies.
If you join an email list, your signup may be sent to an email service provider used by Card Signal to manage subscriptions and send messages. You can unsubscribe from marketing emails. Card Signal will not intentionally send misleading or deceptive email.
Sharing Information
Card Signal does not sell personal information for money. Information may be processed by service providers used for hosting, accounts, databases, email, analytics that you allow, affiliate measurement, security, or payments if paid services are added. Those providers operate under their own terms and policies.
Retention and Your Choices
We keep account and collection information while it is needed to provide the service, meet legal obligations, resolve disputes, or protect the site. You may export collection data from My Collection. Requests to access, correct, or delete account information can be sent to cardsignalapp@gmail.com. We may need to verify the request.
Security
Card Signal uses account authentication, private database rules, and server-side handling for secret credentials. No online system can guarantee absolute security, so use a unique password and protect access to your email account.
Children's Privacy
Card Signal is intended for general collector audiences and is not directed to children under 13. We should not knowingly collect personal information from children under 13.
