Proso Draft and Revise

Proso Draft and Revise is built to work on your device. It has no accounts and no ads, and it does not track you across apps or websites.

Data you enter

What you write is saved as plain files. If you are signed in to iCloud and leave iCloud on in the app, those files live in your own iCloud Drive, in the Proso folder, and sync between your devices. If not, they stay on your device. Earlier versions of each file are kept on the device they were written on. We cannot see any of it. Files in iCloud Drive stay there until you delete them, even if you delete the app.

Data we collect

We collect a small amount of data that is not linked to your identity:

Crash reports (via Sentry): technical details when the app crashes, used to fix bugs.

The app has no usage analytics.

Whether you have bought the premium features is checked with Apple on your device; we do not receive it.

We do not sell data, share it with data brokers, or use it for advertising.

Purchases

Premium features are a one-time in-app purchase, not a subscription. Payments are handled by Apple and we never see your payment details. Restore the purchase on any device signed in to the same Apple ID.

Children

The app is not directed at children under 13 and does not knowingly collect their data.
