Zero data retention for document photos.

What happens to your photo

A photo you choose to scan is processed only to read the facts needed for your deadline, such as dates, amounts, and notice periods. The source photo has zero data retention and is discarded after that request completes.

What stays on your iPhone

The details you confirm, such as the name, the deadline, any amounts, reminder timing, and the optional calendar preference, are saved locally on your device. DueCalm does not require an account.

What the scanning service counts

Scanning costs us money per photo, so the service keeps a few small counters to stop one device or one subscription running up the bill. Each is a number, nothing else.

One is an anonymous device identifier the app generates for itself — a random string, not your Apple ID, not an advertising identifier, and never used to follow you anywhere. The others are counters held against a one-way hash of your subscription, so the stored value cannot be traced back to the subscription, the payment, or you. Those expire on their own, one after a day and one after thirty days. The counters kept against the device identifier are held in memory only. They are never written to a database, and they clear when the service restarts.

No document, date, amount, label, or photo is involved in either. Nothing here is shared with anyone, and none of it is used for advertising or analytics.

Purchases

DueCalm Premium is a yearly subscription, and it starts with a 7 day free trial. Apple handles the payment; we never see your card, your name, or your billing details. We use RevenueCat to check whether the subscription is active, which means RevenueCat holds the anonymous device identifier above and the fact of the subscription. That is all the app learns: whether it is active.

This website

duecalm.app uses Cloudflare Web Analytics for aggregate visit counts. It sets no cookies, does not fingerprint your browser, and cannot identify you or follow you to other sites. It runs on the website only — the iPhone app contains no analytics of any kind.

You confirm every deadline

AI can misread a page. DueCalm always asks you to check the details before a reminder is saved.
