Privacy
DealDex keeps marketplace keys on your device. Sign-in is optional and only backs up those keys to your account.
What stays on the phone
API keys you paste in Settings (eBay, Mercari, JustTCG, PriceCharting, pokemontcg.io, and other desks) live in on-device storage. The apps scan marketplaces from the device. They do not send those keys to DealDex servers.
Optional account
If you sign in, DealDex stores your email and any keys you choose to back up so you can restore them on another device. You can use the apps without an account.
Website analytics
The DealDex website uses Vercel Web Analytics to count visits and page views, and Vercel Speed Insights to measure Core Web Vitals (paint, layout, and interaction timing). Those products do not use cookies and do not identify you. Native apps do not send those web events.
Notifications
The iPhone app may ask to send local alerts when a listing matches a rule you set. You can decline. DealDex does not send marketing push.
Contact
Questions: use the email on the App Store or Play listing. This page is the privacy policy for the DealDex website and the native apps.
