I hold as little about you as the site can work with, and I do not sell any of it to anyone.
What I hold
- Your name and email, because you typed them when you signed up.
- Your password — scrambled, by the database service I use. Nobody can read it back, including me.
- Whether your subscription is running, its renewal date, and a reference number that links your account to Stripe.
- Your practice attempts — when you ran the test, how far you got, what ended it.
- Which device is signed in right now, so one account cannot be used in two places at once.
What I never hold
Your card details. Paying happens on Stripe’s own pages. Your card number never reaches this site at all, so it is not mine to lose.
Who else is involved
- Supabase stores the accounts and practice records.
- Stripe takes the payment, and as the seller of record also handles the sales tax on your purchase.
- Vercel runs the website.
That is the entire list. I do not sell your details, I do not rent them to advertisers, and there is no advertising or third-party tracking on this site.
Cookies
Two, both needed. One keeps you signed in. The other records which device holds the account, so the one-person-at-a-time rule works. No advertising cookies, no analytics cookies.
How long I keep it
While you are subscribed, and 30 days after a subscription ends — so coming back inside a month restores everything. After 30 days the account and its records are deleted. An account that signs up and never subscribes is deleted after 30 days too.
Your say over it
Email xndr442@icloud.com and I will send you a copy of what I hold about you, fix anything that is wrong, or delete your account and its records outright. Deleting is permanent and takes your practice history with it.
Children
This is a commercial-licence practice tool for adults. It is not intended for children under 13, and I do not knowingly hold their details.
