Finding your install ID

Stowbook has no accounts. Instead, each install gets a random ID that links your subscription and the little data our server keeps. To find it, open Stowbook and go to Settings → Privacy. The install ID is listed there; tap it to copy, then paste it into your email. It contains nothing about you or your inventory.

Frequently asked questions

My items aren’t showing up on my other iPhone or iPad.

Stowbook syncs through your private iCloud database. Check that both devices are signed in to the same Apple Account, that iCloud Drive is on, and that Stowbook is allowed to use iCloud in Settings → your name → iCloud. Settings → iCloud in Stowbook shows the sync status. Sync needs an internet connection and some free iCloud storage; large photo libraries can take a while the first time, so leave the app open on Wi-Fi.

Inventories don’t sync between different Apple Accounts.

How do I restore Pro on a new device?

Make sure you’re signed in to the App Store with the Apple Account you bought Pro with, open Stowbook and go to Settings → Pro, then tap Restore. Pro becomes active again within a few seconds. This works for subscriptions and the lifetime purchase.

Still not working? Email us with your install ID and the date of purchase. Your Apple receipt email has it.

How do I cancel, or get a refund?

Subscriptions are managed by Apple. On your iPhone or iPad open Settings → your name → Subscriptions → Stowbook and tap Cancel Subscription. Cancel at least 24 hours before the renewal date to avoid the next charge, including at the end of a free trial. You keep Pro until the period you paid for ends, and your items are never deleted.

Refunds are handled by Apple at reportaproblem.apple.com; we can’t issue App Store refunds ourselves.

How do I export my inventory?

Open Reports and choose an export: CSV (free) for spreadsheets and other apps, or a PDF report (Pro): the full inventory, by place, low stock, or the insurance home inventory with photos and totals. Exports use the standard share sheet, so you can save them to Files, AirDrop, email or print them.

Can I import from a spreadsheet or another inventory app?

Yes. Export a CSV from your spreadsheet or current app, then in Stowbook go to Reports → Import CSV. You’ll see a preview where you match each column to a Stowbook field before anything is added. Places in a column like “Garage / Shelf B” become nested places.

How do I print QR labels?

Open a place or an item and tap Label, or select several in Reports → Labels (Pro). Pick a sheet: Avery 5160 / L7160 (30 per sheet), Avery 5163 (10 per sheet), Avery 22806 (12 square labels) or a single 2 × 1 inch label. Print with AirPrint or share the PDF. If labels don’t line up, set the printer’s scaling to 100% (“actual size”) and paper size to Letter or A4 to match your sheets.

Scanning a label with Stowbook’s Scan tab, or with the iPhone Camera app, opens that place or item.

How do AI scans work, and why was one wrong?

AI Photo identifies one item, AI Shelf finds up to 30 items in one photo, and Receipt reads the lines of a receipt or packing slip. With your consent, the app sends that one image over an encrypted connection to our server, which asks Google’s Gemini AI and sends a draft back. Our server doesn’t keep the image or the result. Free includes 3 AI scans; Pro includes up to 300 a month.

AI can mistake similar products, miscount crowded shelves and misjudge values, so every suggestion is a draft you check before saving. Good light, a plain background and the label or model number in view help. Values are estimates, not appraisals.

I’m not getting low-stock alerts.

Alerts need a minimum set on the item, and Stowbook needs permission to send notifications: check Settings → Notifications → Stowbook in iOS and the low-stock switch in Stowbook’s Settings. Items below their minimum always appear in Reports → To restock.

Is my inventory backed up?

Your inventory lives on your devices and, with iCloud on, in your own iCloud, which keeps your devices in sync and lets a new device download it. We don’t keep a copy, so we can’t restore it for you. Export a CSV or PDF now and then and keep it somewhere safe as an extra copy, especially your insurance report.

How do I delete my data?

In the app: delete items, places or a whole inventory; deletions sync to your other devices. On a device: deleting the app removes what’s stored on it. In iCloud: go to iOS Settings → your name → iCloud → Manage Account Storage → Stowbook and delete its data. That removes it from all your devices.

On our server we only keep an install record, scan counters and usage analytics linked to your install ID (see the privacy policy). Email us your install ID and we’ll delete them. To stop new analytics, turn them off in Settings → Privacy.
