Privacy Policy

Last Updated: June 19, 2026

1. Introduction

At ReviewFlo, we build serverless review pipelines designed to maximize customer engagement while maintaining privacy. Because of our architecture, we do not store customer reviews on our own servers. This Privacy Policy details how data flows through our infrastructure and the measures in place to safeguard it.

2. Data Collection & Direct Logging

When a customer submits a review via one of our custom storefront review forms, the system collects:

  • Customer Name
  • Star Rating
  • Feedback Comments
  • Timestamp of submission

Critical Framework Design: Our backend routing employs a database-less architecture. This review data is never saved, cached, or logged on a database owned by ReviewFlo. Instead, it is routed securely in real-time through an Apps Script endpoint directly to the business owner's private Google Sheet.

3. Cookies and Local Browser Storage

ReviewFlo does not use tracking cookies, analytics pixels, or behavior monitoring tools.

We use browser-based sessionStorage purely to preserve state preferences. Specifically:

  • Theme Preference: To remember whether you selected the light or dark styling theme (via sessionStorage.getItem('theme')).

4. Third-Party Services

Because we build serverless systems, our review widgets interact with the following cloud networks:

  • Google Drive/Sheets API: Receives and logs review data (subject to Google's Privacy Policy).
  • Vercel & GitHub: Delivers the physical HTML/CSS templates globally (subject to Vercel/GitHub Privacy Policies).
  • Cloudflare: Manages domain DNS caching and routing (subject to Cloudflare's Privacy Policy).

5. Client Account Data

For shop owners buying our templates: we log contact details, business name, and setup parameters for invoicing and domain assignment. We do not sell, rent, or distribute this metadata to third parties.

6. Updates to this Policy

We reserve the right to revise this Privacy Policy to reflect changes in our templates or infrastructure. The top date indicates when the most recent amendments occurred.
