Terms of Use

Commonplace · last updated 10 September 2026

Plain versions first: your notes belong to you, the subscription pays for the machine work, and you can leave with everything at any time.

What Commonplace does

You write notes about what you read. Commonplace stores them, and uses a language model to produce a title, a quoted line, a forward-looking prompt, three follow-up questions, and an end-of-book account assembled from what you wrote.

Your content

What you write stays yours. Using Commonplace grants no ownership of it and no licence to publish it, sell it, or show it to anyone else. The only thing done with it is running the features above for you.

Your notes are not used to train any model — not ours, not Anthropic's.

Your own words are never edited or rewritten. Generated text sits alongside them and is always visibly marked as generated.

The subscription

A new account includes a free allowance — twenty recaps and one end-of-book account — which needs no payment and no card. After that, generating new material requires a subscription.

Subscriptions are sold through the App Store, at the price shown in the app before you buy. They renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Your Apple account is charged for the renewal within 24 hours of the period ending. You can see, change or cancel a subscription in your Apple account settings; cancelling stops the next renewal and leaves the current period running to its end.

Prices may change. If they do, it applies from your next renewal and you will be told before you are charged.

What never requires a subscription

Reading everything you have written, and exporting all of it, works whether or not you have ever paid, and continues to work after a subscription ends. Losing access to a subscription must not mean losing access to your own writing.

Deleting your account

You can delete your account from inside the app. It removes your account and everything attached to it, permanently and immediately. Export first if you want to keep anything, because there is nothing to restore afterwards.

Fair use

Commonplace is for one person's reading notes. Do not use it to store or generate unlawful material, do not attempt to break, overload or reverse-engineer the service, and do not resell access to it. Accounts doing any of these can be suspended.

What is not promised

Commonplace is provided as it is. It is a small independent app: it can be unavailable, it can lose a generated title, and the questions it writes can be unhelpful or wrong. Nothing it produces is advice of any kind. Keep your own export if your notes matter to you — and they should, which is why the export is free and always available.

To the fullest extent the law allows, liability for any loss arising from using Commonplace is limited to what you paid in the twelve months before the loss.

Ending

You can stop at any time by cancelling and deleting your account. Commonplace may end an account that breaks these terms, or stop operating entirely — in which case you will be given notice and time to export before anything is deleted.

Apple

These terms are between you and Commonplace, not Apple. Apple is not responsible for Commonplace or its content, and has no obligation to provide support for it. If Commonplace fails to conform to any warranty, you may tell Apple, and Apple will refund the purchase price; Apple has no other warranty obligation. Apple is not responsible for any claim relating to Commonplace, including product liability, legal non-compliance, or consumer protection claims, and is not responsible for handling any third-party claim that Commonplace infringes intellectual property rights. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.

Changes

If these terms change, this page changes and the date at the top moves. Anything that materially affects your notes or what you pay will be told to you in the app rather than left here to be discovered.

Governing law

These terms are governed by the laws of the State of Colorado, United States, without regard to its conflict of law rules.
