Terms of use

You need to be at least 13 to use Stacks. Use your real name and an email address you can read, keep your password to yourself, and keep one account per person. You're responsible for what happens under your account.

The demo is a sandbox anyone can try; it, and everything in it, is deleted after a day.

Your shelf, notes and everything else you add stay yours. You let Stacks store them and show them to the people you choose: your friends, anyone you share a shelf with, and anyone you give your public link to. Don't post anything unlawful, hateful, or that isn't yours to share, and don't use Stacks to harass anyone.

Stacks keeps track of who has which book and when it's due, but the books and the arrangements are between you and your friends. Stacks isn't responsible for a book that comes back late, damaged, or not at all.

The free plan holds 100 books (200 on a shelf shared with someone you live with), with no limit on friends. Stacks Plus lifts the book limit for $3 a month or $24 a year, in US dollars, plus any sales tax or VAT that applies. One subscription covers everyone on a shared shelf.

• Renewal. Plus renews automatically at the end of each month or year until you cancel.
• Canceling. Cancel any time from Settings. Plus stays on until the end of the period you've paid for, then your account goes back to the free plan.
• Refunds. Payments aren't refunded for part of a period, except where the law says otherwise. If you were charged by mistake, get in touch and it'll be put right.
• Payments. Stripe processes payments, and Stacks never sees your card. At checkout Stripe, or its Link service, may act as the seller and collect tax; its terms apply to the payment too.
• Changes. If the price or the free plan's limits change, you'll hear by email at least 30 days before it affects you. Going over a limit never deletes or hides anything.

Don't try to break into accounts or the service, overload it, scrape it, or use it to send spam. Accounts that do may be suspended.

Titles, covers and descriptions come from Open Library and can be wrong. You can edit them on your own books.

You can stop using Stacks whenever you like. You can export your shelf, and delete your account, from Settings; deleting it cancels any subscription. Stacks may close an account that breaks these terms, and will tell you why.

Stacks is provided as it is, without guarantees that it will always be available or free of mistakes. As far as the law allows, Stacks isn't liable for indirect losses, and its total liability to you is limited to what you've paid in the last 12 months. Nothing here takes away rights you have under consumer law where you live.

These terms may change as Stacks does. For significant changes you'll get notice by email or on the site before they take effect. What Stacks keeps about you is in the privacy policy.
