Privacy policy
Last updated: May 30, 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).
5. Third parties
- Supabase — 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).
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 only use functional cookies (session/authentication via Supabase) and anonymous analytical cookies (Vercel). No tracking or advertising cookies are placed.
