FAQ

Setup#

Do I need both the Nerja Tag and the SDK?

Use the Tag for your website and the SDK for your app. They feed the same lead, so people who use both are one person.

Do I have to write code?

Website: one pasted line. Store connections: none. App: a few lines for init, identify and track.

Cost#

Does my client need a paid Firebase account?

No. FCM is free on Firebase's free plan. iPhone delivery additionally needs an Apple Developer account for the app owner, which is Apple's fee.

Push#

What if the person does not have my app?

They get no app push. They are reached on the other channels, or by web push if they allowed notifications on your site; a tap opens your website page.

Can I put any link in a push?

Only links on your own website. Anything else is replaced by your store link — so a template can never send customers elsewhere.

Why did some contacts not receive my campaign?

Open the campaign's recipients: each skipped or failed contact has a reason (no token, daily limit, do-not-contact…).

Data#

Is shopper data shared with AI models?

No contact details are sent to AI models — only aggregate audience summaries and product context.

Can customers ask for their data to be deleted?

Yes — see the data deletion page.
