Money data on your iPhone

Transactions, wallets, budgets, people you lend to or borrow from, categories, and related notes are stored on your device. Cloud backup of that ledger is not part of this release.

You can export transaction logs as CSV from the app. CSV covers logs only (date, note, amount, category, type). Budgets, Obligations, wallets, assets, and profile are not included. Erase data removes the local ledger on that iPhone.

Account (optional)

Signing in is optional. If you choose Sign in with Apple or Google, we store an account identifier and, when the provider shares it, your name and email. That account is hosted by our authentication provider (Supabase) so you can reconnect the same identity later. We also send that account identifier to RevenueCat so Casi Pro stays attached to the same person if you restore purchases.

Display name is saved on the cloud profile so it comes back when you sign in again. Profile photos stay on this iPhone. Usernames for finding other people are not part of this release.

Signing out disconnects the account. It does not delete the money data already on the iPhone. You can delete the cloud account from the app; that removes the signed-in identity, not the local ledger.

Purchases

Casi Pro is sold through the App Store. Apple processes payment. We use RevenueCat to confirm whether your Apple ID has an active Pro subscription or lifetime unlock so the app can turn on paid features. We do not receive your full card number.

Permissions

The app may ask for:

• Microphone and speech recognition, only if you hold the add pad to log by voice. We use that to draft a transaction. The app prefers on-device recognition. If the iPhone cannot do that, Apple’s speech service may transcribe the audio. We do not save the recording to your account. On supported devices you can optionally refine the line with on-device Apple Intelligence.
• Face ID or device passcode, only if you turn on app lock.
• Photos, if you pick a profile photo (it stays on this iPhone) or scan a receipt. Receipt OCR runs on-device. If Apple Intelligence is not available and you agree, receipt text, and if needed a receipt image, may be sent to a cloud model (Gemini Flash, via our servers) only to read that bill. We do not send wallets, budgets, Obligations, or the rest of your ledger.
• Notifications, if you enable a daily reminder to log spending, or loan settle reminders.
• Contacts. The system contact picker can fill a person’s name for Obligations. We do not upload your address book.

Widgets

Home Screen widgets read a local snapshot of budget and spending figures through an App Group on the same iPhone. That snapshot does not leave the device.

What we do not collect

We do not run advertising trackers in the app. We do not sell your ledger to data brokers. Features that are not in this release (including cloud ledger sync) are described in the app as coming later and are not covered here until they ship.

Waitlist website

When you join the waitlist on this site, we collect your email address and platform preference (Apple or Android). We use this to notify you about CASI and to understand demand.

Signups are stored in our database. We use Resend to send waitlist confirmation and launch messages to the email you provide.

Cookies and analytics

This marketing site does not use advertising cookies or sell your data to advertisers.

We use a privacy-friendly analytics tool (Umami, hosted at analytics.ziteox.com) to understand basic site traffic, such as page views and referrers. It is configured to avoid advertising trackers and does not require a cookie banner for ads profiling.

Our hosting provider may also keep standard technical logs (for example IP address, browser type, and request time) needed to run and secure the site.

Feedback

If you send feedback from the app, we store the message, an optional reply email, app version, device and iOS version, and your account identifier if you are signed in. That is only to reply and fix issues. It is not used for advertising.

Your choices

You can delete your waitlist email by writing to us. In the app you can sign out, delete the cloud account, erase local data, and manage or cancel subscriptions in iOS Settings → Apple ID → Subscriptions.
