Privacy
Last updated September 5, 2026
The short version: we hold your email address and which packs you bought. Your colouring never leaves your own device, and we do not run ads, trackers or analytics.
What we store
- Your email address and account id, so a pack can belong to someone.
- Which packs you own, and the date and amount of each purchase.
That is the entire list.
What we never see
- Your card details. Payment happens on Stripe's own checkout page. Card numbers never touch this site or our servers.
- Your colouring. Which colours you put where, your finish and palette choices, and your progress are saved in your own browser's local storage. They are never uploaded. Clearing your browser data erases them, and they do not follow you to another device.
- Your password. Sign-in is handled by Clerk; we never receive it.
Who else is involved
- Stripe — payments and sales tax. Sees your name, email, card and billing address, under Stripe's privacy policy.
- Clerk — accounts and sign-in. Sees your email and login activity.
- Cloudflare — hosting. Handles the requests and keeps short-lived server logs.
- Google Fonts — the two typefaces this site uses.
We do not sell your data, share it for advertising, or send marketing email you did not ask for. The only email we send is about a purchase you made.
Cookies
Only what sign-in requires to keep you logged in, and Stripe's own cookies on its checkout page. No advertising or analytics cookies.
How long we keep it
Purchase records are kept as long as you hold the pack, and afterwards for as long as tax law requires us to keep sale records. Everything else goes when your account does.
Your choices
Email support@practicalbyteapps.com to get a copy of what we hold on you, correct it, or delete your account and everything attached to it. We will do it, and we will not ask you to justify it. Deleting your account removes your packs, which cannot be undone.
Children
The pages are made for anyone to colour, but an account and a payment method are needed to buy one, so accounts are for adults. We do not knowingly collect information from children under 13. If you believe a child created an account, email us and we will remove it.
