Simple, private apps for parents teaching at home
No ads. No tracking. Just honest logic.
Card Vault helps a collector track what’s in the box. Spelling Bee and Math Flash turn practice into something a kid actually wants to do. One sign-in works across all three, and we only collect what each app actually needs to run.
Track what’s in the box.
Snap a photo of any sports card. We identify it, track it, and keep your collection’s value up to date.
Open →Show a picture, play the sound, spell the word.
Build word lists for a student, and let practice do the rest — a picture and a pronunciation for every word, generated once and reused every time.
Open →Flip the card, solve it, watch the streak grow.
Build decks of math facts for a student and let practice build speed and confidence, one flash card at a time.
Open →Simple
No settings to dig through, no onboarding tour. Sign in, add what you’re tracking or teaching, and go.
Privacy first
We only collect what each app actually needs to work — an email to sign you in, and the content you add. Nothing more.
No ad tracking
No ad networks, no cross-site tracking, no selling data. The only analytics we run is page-load performance timing — nothing about you personally.
Built for parents teaching
Spelling Bee and Math Flash are built around a parent or teacher setting up practice for a kid — not around getting a kid to sign up for yet another account.
