Support
Need help with Walnut? We're happy to assist. Walnut is a fully on-device,
privacy-first document vault — there's no account and no cloud service, so most questions are
about the app itself.
When emailing, it helps to include your device model,
iOS/Android version, and a short description (or screenshot) of the issue. Please don't send any
sensitive document contents.
Frequently asked questions
Is my data private?
Yes. Walnut is 100% on-device. There is no account, no server, no analytics,
and no third-party tracking. Your documents, notes, and cards never leave your phone unless you
choose to back them up to your own cloud (iCloud Drive / Files).
How does search work?
Walnut reads the text inside your photos and scans using on-device OCR
(text recognition) and transcription. You can then search by any word — across document names,
extracted text, transcripts, and your notes — with no internet connection required.
How do reminders work?
Add a due date to any document (e.g. insurance, warranty, passport). Walnut
schedules local notifications and can even suggest a due date it reads from the document. You can
set up to three alert offsets (on the day, 1 week before, 2 weeks before).
How do I back up my data?
On iOS, Walnut can back up to your own iCloud Drive. The backup
is stored in your personal cloud — it never touches our servers (we don't have any). Open
Settings → Backup and tap Back up now, or enable auto-backup.
How do I restore on a new phone?
Install Walnut on the new device, sign in to the same iCloud account, then open
Settings → Backup → Restore. Walnut will pull your latest backup from your iCloud Drive.
Restores resume automatically if interrupted.
What is App Lock / Face ID?
You can optionally protect the app with Face ID / Touch ID / passcode under
Settings → App Lock, with an auto-lock timeout. Secure cards (IDs, card numbers) are kept
behind this lock.
What file types can I save?
Photos, videos, PDFs, documents and spreadsheets, voice notes (transcribed on
device), rich-text notes, checklists, secure cards, and links. You can save single items or whole
multi-image collections.
The app asked for Camera / Photos / Microphone / Notifications — why?
All permissions are optional and requested only when needed: Camera to scan,
Photos to import, Microphone to record voice notes, and Notifications to deliver reminders. Everything
is processed locally on your device.
How do I delete my data?
Deleting an item moves it to Recently Deleted (30-day restore). To remove everything,
delete the app — because all data is on-device, uninstalling removes your local content. Any backup you
created lives in your own iCloud Drive and can be deleted from there.
