What Quadsheet stores
Your email address, a display name, and the contents of your sheet: box labels, projects, tasks, and when you crossed them off. If you sign in with Apple or Google, we receive the email and name they share; we never see a password because there is none.
Where it lives
On Supabase, in a database in the United States, over encrypted connections. Sign-in emails are sent through Resend. If the app crashes, a report with the error, your device model and the app version goes to Sentry so we can fix it; it never includes your tasks, your box names or your email address. Nothing is sold, shared with advertisers, or used for anything other than showing you your sheet. Subscriptions to Quadsheet Plus are checked through RevenueCat; the next section says what that involves.
Subscriptions
Quadsheet Plus is bought in the iPhone app through the App Store. Apple processes the payment. We never see your card or any other payment details.
To know whether a subscription is active we use RevenueCat, which works on our behalf. When you use the iPhone app, RevenueCat receives your Quadsheet user id, which is a random identifier and not your email or name, along with basic technical details such as the app and iOS version. If you subscribe, it also receives the purchase information Apple provides for Quadsheet: which subscription, when it started and when it renews or ends, whether it is a free trial, the price and currency, the App Store country, and Apple's transaction identifiers. RevenueCat never receives your tasks, your sheets or your email address.
RevenueCat tells our server when a subscription starts, renews, is cancelled or ends. With your account we store your plan, when Plus renews or ends, which subscription you chose, whether it is a trial, whether it will renew, whether Apple reported a billing problem, and a log of those notices with no prices or transaction identifiers. People you share a box with cannot see any of this.
Who can see it
Only you, and anyone you share a box with. A shared box shows its projects and tasks to the people you invited by email, and nothing else on your sheet. Access rules are enforced in the database itself.
Deleting your account
Open the account menu in the app and choose Delete account. Your account, your sheets and every task on them are removed immediately and cannot be recovered. Your plan and subscription record go with them, and the log of subscription notices keeps no link to you.
Deleting your account does not cancel a subscription bought in the App Store; cancel it in your Apple Account settings. To have RevenueCat delete its record of your purchases as well, ask through the support form and we will request it.
