Privacy Policy
Effective July 8, 2026
PokeMasterSet is a small, independently-run project. This page explains exactly what we collect, why, and how you can delete it — in plain language, matching what the app actually does.
If you don't sign in ("local mode")
You can use the whole binder, dashboard, and want list without an account. In that case your collection — which cards you've marked owned, your quest tier, your display settings — is saved only in your browser's local storage. It never leaves your device, and we never see it.
If you sign in with Google
Signing in lets your collection sync across devices. We deliberately request the smallest Google sign-in scope available — your email address only. We don't request your name or profile photo, don't receive or store your Google password, and never post anything to your Google account.
Once signed in, we store:
- Your email address, held by Supabase Auth to identify your account and let you sign back in
- In our own database: an account identifier plus your display language, eBay region, and currency preferences
- Per Pokémon species you track: which cards you've marked collected (and when), your chosen quest tier, sort order, and any extra-content toggles
This data lives in our Supabase project (hosted in the United States) and is only ever read or written for your own account, enforced by database-level row security — no PokeMasterSet staff account has a separate way to browse other users' collections.
Cookies
Signing in sets one authentication cookie (managed by Supabase) so you stay signed in between visits. We don't use advertising cookies or cross-site tracking cookies.
Analytics
We use Vercel Analytics and Speed Insights to see aggregate traffic and page-load performance — how many people visit and how fast pages load. These don't use tracking cookies, don't sell data to advertisers, and don't identify you individually.
eBay affiliate links
"Search on eBay" links from your want list may include an eBay Partner Network affiliate id. If you buy something after clicking through, we may earn a small commission — this costs you nothing extra. We don't receive any information about your eBay account or purchases; eBay's own privacy policy covers what happens once you leave our site.
Who else sees this data
We rely on a few outside services to run PokeMasterSet, each only for the purpose listed:
- Google — sign-in only
- Supabase — authentication and database hosting
- Vercel — website hosting and the analytics described above
- eBay Partner Network — affiliate link tracking, described above
We don't sell your data to anyone, ever.
Deleting your data
You can clear your collected cards for any species anytime from that species' Settings page. To delete your account and every piece of data tied to it, email us — see below — and we'll remove it.
Children's privacy
PokeMasterSet isn't directed at children under 13, and we don't knowingly collect account data from them. If you believe a child has created an account, contact us and we'll delete it.
Changes to this policy
If what we collect or how we use it changes in a meaningful way, we'll update this page and its effective date above.
