Membership Navi
Membership Navi keeps your membership cards, loyalty cards, and point cards in one app, and shows their barcodes exactly as they were scanned. Your cards sync through iCloud to all your devices, including Apple Watch.

Before you write
A few quick checks for common issues:
- Camera not working? Go to iPhone Settings → Privacy & Security → Camera → enable access for Membership Navi.
- Cards not appearing on another device? Make sure both devices are signed into the same Apple Account with iCloud enabled. The Settings tab in the app shows whether iCloud Sync is on. First sync can take a minute.
- Barcode not reading at the register? The screen goes to full brightness automatically while a code is displayed (you can toggle this in Settings). If a specific shop's scanner still refuses a code, email us the shop and card type and we'll investigate. Faithful reproduction is this app's whole job.
- Watch shows "Could not generate code"? Open that card once on your iPhone and give iCloud a moment to sync, then try again on the watch.
Frequently Asked Questions
- Will the barcode really scan like my physical card?
Yes. Membership Navi remembers the exact barcode format and settings at scan time (Code 128, EAN, Codabar, QR, and so on) and regenerates the code in the same configuration, not a generic re-encoding. - What happens if I lose my phone or reinstall the app?
Your cards live in your personal iCloud. Sign into the same Apple Account and they come back automatically. - Does it work on Apple Watch?
Yes. The watch app shows your cards full-screen on a white background for easy scanning, and it keeps its own copy of your cards, so it works even when your iPhone isn't with you. - Does it need an internet connection?
Only for iCloud sync. Showing your cards and their codes works completely offline. - Can the developer see my cards?
No. Your data is stored on your devices and in your personal iCloud database, which only you can access. There is no server of ours, no account, and no analytics. - Which code types are supported?
QR, Code 128, Code 39, Code 93, EAN-13, EAN-8, UPC-E, ITF, Codabar, PDF417, Aztec, and plain member numbers. - Why can't I edit a scanned code's number?
By design. A scanned code is reproduced exactly as it was on your card, so editing it would break that guarantee. To change a card's code, rescan the card. Cards you typed in by hand stay editable. - Does it access my entire photo library?
No. You pick a single photo with the system photo picker; the app never receives access to your library.
Manual
Your cards
The Cards tab lists everything you have saved, sorted by name. Tap a card to show its code. The search field above the list matches both card names and card numbers, which is the quickest way through a long list.
Card numbers are deliberately not printed in the list. Anyone glancing at your screen would otherwise see every membership number you own at once.
Showing a card
Tap a card and it fills the screen, with the number underneath so you can read it out if a scanner refuses. The screen also goes to full brightness while a code is showing and returns to your usual level when you leave, because shop scanners have a much easier time with a bright screen.
The code is drawn so that every bar lands on whole screen pixels. That sounds pedantic, but it is what lets the laser scanners at a register read the screen: they decode from the ratios between bar widths, and a barcode that has been stretched by a fraction of a pixel has uneven bars.
Adding a card
The Add tab offers three ways in. Tap the switcher at the top, or swipe between them:
- Camera — point it at the barcode or QR code on a physical card.
- Photo — pick a photo or screenshot that already has the code in it.
- Manual — type a member number in, for cards that are just a number.
While you are scanning, the screen shows nothing but the camera: no forms to fill in. Once a code is found the app confirms it and shows you the decoded number, so you can check it against the card in your hand before saving. Then you give it a name and a colour. If something looks wrong, Discard puts you straight back to the camera.
You can also send a code in from another app: screenshot it, tap Share, and choose Membership Navi. It scans the image and opens the same confirmation screen.
Editing and deleting
Swipe a card left to delete it, or right to edit it. Editing lets you change the name and the colour stripe.
On a scanned card the number and its format are shown but cannot be changed. That is on purpose: the app reproduces the code exactly as it was on your card, and editing the value would quietly break that promise. To change a scanned card's code, add the card again by scanning it. Cards you typed in by hand stay fully editable.
Apple Watch
The watch app lists the same cards and shows any of them full-screen on white, which is as bright as watchOS allows. It keeps its own copy, so it works with your iPhone in a bag or at home.
New cards appear on the watch once iCloud has synced them, which usually takes a moment. If a card says it cannot generate a code, open it once on your iPhone and give sync a little time.
Settings
Auto Max Brightness controls the full-brightness behaviour described above. Turn it off if you would rather the app left your screen alone.
iCloud Sync is a status line, not a switch. It reports whether your cards are syncing, so a silent failure is visible: if it says you are not signed in, sign in to iCloud in the Settings app and your cards will sync and be restored if you ever reinstall.

Privacy Policy
Last Updated: July 2026
Introduction
Membership Navi is built around a simple principle: your data belongs to you. This Privacy Policy explains what information the app accesses and how it is handled.
Camera Access
The app uses your device's camera to scan barcodes and QR codes on your cards. The camera feed is processed entirely on your device. No images or video frames are ever stored, uploaded, or shared with anyone.
Photo Access
When you add a card from a photo, you pick a single image using the system photo picker. The app never receives access to your photo library.
Your Cards and iCloud
The cards you save are stored on your device and, if you use iCloud, synced through your personal iCloud database (Apple CloudKit) so they appear on all your devices, including Apple Watch, and are restored when you reinstall the app. This database belongs to your Apple Account: we cannot read, access, or share its contents. We operate no servers of our own.
No Data Collection
We do not collect, store, or process any personal information. The app does not require an account or any form of registration, and contains no analytics, advertising, or tracking of any kind.
Purchases
Membership Navi is a one-time purchase handled entirely by Apple's App Store. We never receive your Apple ID, payment method, or any other payment information.
Children's Privacy
Because no personal data is collected by us, Membership Navi complies with the Children's Online Privacy Protection Act (COPPA) and similar regulations worldwide.
Changes to This Policy
We may update this Privacy Policy from time to time. Changes are effective immediately upon posting. We encourage you to review this page periodically.
