Frequently asked
Do I need an account?
No. There is nothing to sign up for. Open the app and start recording.
Where is my data stored?
On your iPhone, in the app's own storage. It leaves the device only if you export it yourself, or if you switch on the optional iCloud Drive backup — which copies into your iCloud account, never to us. See our Privacy Policy.
Can you recover my data if I lose my phone?
No — and this is worth understanding before it happens. We have no server and no copy of your records. Turn on Settings › Your data › Copy to iCloud Drive and each automatic backup goes to your own iCloud account, where it survives the phone. You can also export a backup by hand at any time.
How do I move my data to a new phone?
On the old phone, Settings › Your data › Back up everything creates a
.zip containing everything, including your receipt photos — save it to Files or iCloud Drive. On the new phone, install Daybook and use Settings › Your data › Restore › From a file. If you had the iCloud backup switched on, the copies are already there under iCloud Drive → Daybook → Backups (records only, without receipt photos).Can I get my data out?
Yes, always. CSV and JSON export are in Settings, and both are free. Your records are never held hostage.
The scan got something wrong.
Every field on the review screen is editable before you save, and anything the scan was unsure of is flagged rather than accepted silently. Scanning works best on a flat, well-lit receipt. If a particular receipt fails consistently, email it to us — it helps.
Does Daybook send my receipts to an AI?
Only in two cases, and neither is possible until you add an API key of your own. Pressing “Read the photo with AI” sends that receipt's photograph. Switching on the second reading sends the words, numbers and their positions — not the photograph — for scans that came back unclear. Both go to the provider you pick, Google Gemini or OpenRouter, under your own key; with OpenRouter the company hosting the model receives it too. Nothing passes through us. Removing your key stops both.
What languages can it read?
19, including English, Bahasa Malaysia, Chinese, Japanese, Korean, Thai, Vietnamese and Arabic. Choose them in the scan screen's language picker. The app's interface is English only.
Does it connect to my bank?
No. Daybook records what you tell it. Nothing is imported from a bank, and no bank credentials are ever requested.
How do I cancel Daybook Pro?
Settings › Apple Account › Subscriptions on your iPhone — or open Daybook and go to Settings › Daybook Pro, which opens Apple's own management sheet. Cancel at least 24 hours before renewal.
I paid but Pro is not unlocked.
Tap Restore Purchase on the paywall, or in Settings › Daybook Pro. If that does not work, email us with the Apple receipt.
Can I request a refund?
Refunds go through Apple at reportaproblem.apple.com. We have no access to the transaction and cannot process one.
Is there an Android version or an iPad version?
Not yet. Daybook is iPhone-only for now.
I found a bug, or I want a feature.
Email us. A small app changes fast, and requests genuinely do get built.
Still stuck?
Email us directly. There is no ticket queue and no bot — the message goes to the people who build the app.
