Privacy policy

Last updated: September 29, 2026

This is a reference translation. The Dutch version is legally binding.

1. Who are we?

Forms Visualizer (www.formsvisualizer.com) is an online tool to visualize and analyze survey data. The service is offered by the owner of Forms Visualizer, based in the Netherlands.

2. Which data do we process?

  • Account data: email address and name via Google OAuth.
  • Payment data: payments are processed by Stripe; we do not store payment data.
  • Survey data: the data you upload or import is processed solely locally in your browser. We never store these answers on our servers — not even with Pro.
  • Dashboard settings (online snapshots): online syncing is opt-in (off by default). If you enable it, we only store the configuration per dashboard — chart choices, branding, filters, titles and the column headers/question texts (needed to recognize your dataset). Never the answers.
  • Usage data: anonymous statistics via Vercel Analytics.

3. Privacy by design — what is stored where?

Only in your browser

  • ✓ All raw answers
  • ✓ Uploaded CSV/XLSX files
  • ✓ Local snapshots (with data, max 20)
  • ✓ Undo/redo history

Online (logged in only)

  • ✓ Chart choices & layout
  • ✓ Branding (title, colors, logo)
  • ✓ Question column names (form_headers)
  • ✗ No answers

In practice: with Pro we allow up to 50 online snapshots, free users up to 3 non-unlocked snapshots plus all their unlocked forms. In both cases the answers stay solely in the browser where you uploaded them.

4. Legal bases and purposes

  • Performance of the contract (account, credits, Pro subscription).
  • Legitimate interest (security, fraud prevention, technical operation).
  • Legal obligation (Stripe, taxation).
  • Consent (ad measurement via Google Ads; can be withdrawn at any time).

5. Third parties

  • Firebase (Google) — database and authentication (GDPR-compliant, EU hosting possible).
  • Stripe — payment processing (PCI DSS certified).
  • Vercel — hosting and edge delivery.
  • Google Gemini — AI analysis (only prompt text is sent, no personal data).
  • Google Ads — measuring which ads work, only after your consent in the cookie banner.

6. Your rights (GDPR)

You have the right to access, rectification, erasure and portability of your data. Send a request to privacy@formsvisualizer.com.

7. Cookies

We use functional cookies (session/authentication via Firebase) and anonymous, cookieless statistics (Vercel). Only if you click Accept in the cookie banner do we load the Google tag (Google Ads). It sets a cookie to measure whether you came from an ad, whether you create an account, open a dashboard and whether you unlock a form or buy credits (amount and order number, no survey data). If you choose Necessary only, nothing from Google Ads is loaded. You can change your choice below at any time.

8. Google Workspace add-on (Sheets and Forms)

  • The add-on only accesses the spreadsheet or form you have open. It does not read any other files in your Google Drive.
  • The side panel and the chart tab are computed inside your document; the answers stay there.
  • To draw charts in our house style, we send only counts per answer option to formsvisualizer.com, never individual answers. We do not store those counts.
  • Only when you choose to open the full dashboard are the column headers and answers sent to the web app, via a one-time link. They are deleted as soon as the link is opened; a link that is not opened expires after 10 minutes and is then deleted.
  • To recognise your account, the add-on sends a Google-signed identity token with your verified e-mail address. We use it only to tie the one-time link to you, to limit abuse and to pre-fill sign-in.

Forms Visualizer's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. We do not sell this data, use it for advertising or use it to train generalised AI models; people only access it for security, legal obligations or with your explicit consent.
