FAQ

Frequently asked questions

Can't find your answer? Message us on Telegram.

One payment — forever. We don't believe in subscription fatigue. Elfsight and JivoSite charge you $10+/month for years; with us you pay once and forget about it. You get every update as long as the project is alive.

No problem: the code is open-source on GitHub under AGPL. The widget works without our server entirely (deep link → Viber directly). You just self-host it, with no loss.

For those who want our server plus a click-analytics dashboard. It isn't required for the widget to work. Most customers choose Lifetime and never pay anything beyond that one time.

Yes. 30-day money-back, no questions asked. Send us an email and we'll refund you.

Yes, it's just a <script> tag — it can be pasted anywhere. If the platform lets you add HTML, the widget will work.

The browser shows a system prompt “Open in Viber?” or an install link. The user won't get lost.

So companies can't fork our code into a closed SaaS without contributing improvements back. MIT allows that; AGPL doesn't. For regular widget users it makes no difference.

We're 20× lighter, open-source, and ad-free. And we don't charge $100+/year — you pay $39 once.

The code is open — you can audit it. We don't collect personal data. GDPR/CCPA-compliant. No cookies, no trackers.

On the Free plan you need your own VPS + nginx (a 5-minute guide). Lifetime Pro includes a ready-made 1-click setup script for VPS plus instructions for Tilda/WordPress.

Partially, in Lifetime Business. Full white-label is in the Agency plan ($299 lifetime).

Nowhere with us. The deep link works entirely without our backend. We physically can't get the data.

One payment. Forever.
