# Monetization & Scalability

**Authentication & Monetization**

For user authentication and monetization:

* **Google OAuth** streamlines onboarding, reducing friction while maintaining strong security through token-based authentication.
* **Stripe** supports global billing for Premium tiers, 7-day free trials, and token-gated upgrades.

This model enables seamless monetization of high-value features like voice logging, visual meal analysis, or personalized nutrition insights — while allowing free users to engage deeply before committing.

**Scalability & Future-Readiness**

Nuri’s tech stack is built to scale globally and adapt continuously:

* **Horizontal scaling** via cloud-native infrastructure (Node.js + PostgreSQL sharding)
* **Wearable integrations** planned via public APIs (e.g., Fitbit, Apple Health, Oura)
* **Multilingual AI coaching** supported by OpenAI and Whisper — enabling reach across global health communities

As AI models evolve and biometric tracking becomes mainstream, Nuri’s modular system can ingest new inputs (e.g., HRV, sleep scores, glucose monitoring) and output smarter wellness plans. This roadmap positions Nuri not just as an app — but as the **adaptive Wellness OS** for long-term behavioral transformation.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.meetnuri.com/technology/monetization-and-scalability.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
