Who we are
WaxTracker is a personal portfolio tracker for vinyl record collectors, built and operated by Hugo Emmerzael. You can reach us at leen.emmerzael@gmail.com.
What data we collect
- Discogs account info — your username and numeric user ID, obtained when you connect your Discogs account via OAuth.
- OAuth tokens — access token and secret that let WaxTracker read your Discogs collection on your behalf. These are stored encrypted in our database and never shared.
- Collection data — titles, artists, formats, and purchase prices you have in your Discogs collection. Purchase prices are only stored if you enter them.
- Price snapshots — daily marketplace prices fetched from Discogs for records in your collection. This data comes from Discogs, not from you directly.
- Billing information — if you subscribe to WaxTracker Pro, payment is handled entirely by Stripe. We store only a Stripe customer ID — no card details ever touch our servers.
How we use your data
- To display your vinyl portfolio and price history inside WaxTracker.
- To fetch daily price updates from Discogs for records in your collection.
- To manage your Pro subscription via Stripe.
We do not sell, share, or use your data for advertising. We do not use your data to train AI models.
