Cadora

How can we help?

Last updated: 12 October 2026 · Applies to Cadora for iPhone and iPad, version 1.2.0.

Cadora is made by one person. Mail lands in a mailbox that is read, not a ticket queue that isn't. Expect a reply within a few days, in English or Vietnamese.

Before you write

Two things make almost every problem faster to fix:

Never send a screenshot of anything you would not want a stranger to hold. Nothing about your items needs to reach us to answer most questions.

Common questions

Reminders and widgets

Both are on-device: nothing is pushed from a server, so anything that goes wrong is something you can check.

Reminders never arrived

Cadora's reminders are local notifications scheduled on the device. There is no server pushing them, so when one does not appear, the cause is on the device — and that is good news, because every cause is something you can check:

  • Permission. iOS Settings → Notifications → Cadora. If notifications are off, nothing is delivered and the app cannot tell you so.
  • The item has an alert at all. Open the item → Alerts. A lead time has to be set; an item with no alert is tracked but silent.
  • Focus, and Scheduled Summary. A Focus mode can hold notifications back, and Scheduled Summary delivers them in a batch hours later rather than at the moment set.
  • The date already passed. A reminder is scheduled ahead of a renewal date. Editing an item to a date in the past leaves nothing to fire.

If all four are right and it still stays quiet, mail us with the item's renewal date and the lead time you chose.

The widget is stale or empty

The widget reads a copy of your data shared from the app, and iOS decides how often to refresh it — a widget is not allowed to update on demand.

  • Open the app once after installing or after a big change; that is what refreshes the copy.
  • If it stays empty, remove the widget and add it again.
  • On a brand-new device, let the app finish its first iCloud sync before judging the widget.

Folders

Making and using folders

A folder groups items by who or what they are for — Work, Family, a flat you share. Folders are free, and they sync through iCloud like everything else.

  • Make one — on the dashboard, under Folders, tap New folder. Give it a name, and a symbol, a colour or one of your photos.
  • Move items in — open the folder, tap ⋯ and choose Add items… to move several at once, or long-press an item in the Everything list and choose Move to Folder…. You can also pick the folder when editing an item. An item sits in one folder at a time.
  • Delete one — open the folder, tap ⋯ and choose Delete folder. Its items are kept; they just move back to No folder.

Premium, billing and cancelling

Apple holds the billing relationship, not us — which decides who can do what.

Premium, billing, and cancelling

Premium unlocks unlimited items, multiple reminders per item, the advanced insights charts and forecast, CSV and PDF export, and removes ads.

The free tier tracks up to 10 active items. Paused and cancelled items do not count. If you already have more than 10, nothing is taken away — every item stays visible and editable, and only adding a new one asks you to upgrade.

  • Restore a purchase — Settings → Premium → Restore purchases. Premium is tied to your Apple Account, not to a Cadora account, so it comes back on any device signed in to that account.
  • Cancel a subscription — iOS Settings → [your name] → Subscriptions → Cadora. We cannot cancel it for you; Apple, not us, holds the billing relationship.
  • Refunds — Apple issues them: reportaproblem.apple.com. If a purchase went wrong, write to us as well, but the refund itself has to go through Apple.
  • The lifetime option is a one-off purchase, not a subscription, so there is nothing to cancel and it will not renew.
Cancelling something Cadora is tracking

Cadora tracks what you pay for. It cannot cancel it. You cancel with the provider — and where the provider publishes a cancellation page, the item's detail screen opens it for you.

Cadora never connects to your bank or card, and cannot make or stop a payment.

Your data, security and languages

There is no account, so most of this you can do yourself, immediately.

Your data, and getting rid of it

Everything you type stays on your device and syncs through your own iCloud. There is no Cadora server and no account, which is also why there is no "delete my account" button — there is no account to delete.

  • Export — Settings → Export as CSV, or the yearly PDF report. Both are Premium.
  • Delete one thing — delete the item, and its reminders and calendar entries go with it.
  • Delete everything local — delete the app.
  • Delete the synced copy — iOS Settings → [your name] → iCloud → Manage Account Storage → Cadora. Deleting the app alone does not remove what is already in your iCloud.

What is and is not collected is set out in the Privacy Policy. Three things do reach a third party, all of them Google: banner ads for free users; crash reports, which are on by default and can be switched off in Settings → Diagnostics; and analytics about how the app performs, only if you say yes (in Google's privacy form where it is shown, or with Settings → Ads → Show relevant offers). None of them carries anything you typed.

Why does the App Store say data is used to track me?

That label covers ads on the free plan. iOS asks whether Google AdMob may use your device's advertising identifier to personalise ads, and you can decline and still use everything. Nothing you type is sent to advertisers. Premium users are never asked and see no ads. To change your ad choices later, use Settings → Ads in Cadora.

Passcode lock

If you set a passcode in Settings → Security and then forget it, we cannot reset it and nor can Apple. The passcode is not stored anywhere we can reach — only a PBKDF2 derivation of it, on your device. Deleting and reinstalling the app clears the lock along with the local database.

Languages

Cadora is translated into more than 30 languages and follows the language order in iOS Settings. To override it for Cadora alone, use Settings → General → Language inside the app.

Found a translation that reads wrong in your language? That is worth an email — machine translation gets finance wording subtly wrong, and a native speaker's correction is the only reliable fix.
