Privacy Policy

Last updated: 15 August 2026

This policy explains what personal data Vizzie ("we", "us") collects when you use the Vizzie application and website, how we use it, and the choices you have. Vizzie is a tool for turning open data into maps, charts, and tables.

Data we collect

• Account details — your email address and display name, provided when you sign up or sign in (including via Google or Facebook).
• Your content — the projects, maps, charts, and the data sources you follow (open-data portals, publishers, datasets).
• Usage & security events — sign-in events (time and browser type), the storage your downloaded data uses, and a record of exports you create.
• Published-map visits — when someone opens a map you publish, we record the visit for your own analytics. We store a hashed (irreversible) form of the visitor's IP address and an approximate country — never the raw IP.

How we use it

• To provide the service — sign you in, save your projects, and show your usage and analytics.
• To secure accounts and prevent abuse.
• To send essential account emails (e.g. confirmation and password reset), and optional product updates you opt into.

Who we share it with

We do not sell your personal data. We use trusted service providers to run Vizzie, who process data on our behalf:

• Supabase — authentication and database hosting for your account and content.
• Google / Facebook — only if you choose to sign in with them, to verify your identity.
• Mapbox — optional address lookup and routing features, when used.
• Open-data providers you connect to serve the public datasets you map.

Data retention

We keep your account data for as long as your account is active. Raw map-visit records are rolled up into aggregate counts after about 30 days, and old sign-in records are pruned over time. You can delete your account and data at any time — see Data Deletion.

Your rights

Depending on where you live, you may have the right to access, correct, export, or delete your personal data, and to withdraw consent. To exercise these, contact us at the address below or follow the deletion instructions.

Security

Access to your data is restricted so that you can only reach your own records; passwords are handled by our authentication provider and are never stored by us in plain text.

Children

Vizzie is not directed to children under 13, and we do not knowingly collect their data.

Changes

We may update this policy; material changes will be reflected by the "last updated" date above.

Template notice: this page is a good-faith summary of how Vizzie handles data. Review and adapt it (legal entity name, contact address, jurisdiction-specific rights) and have it checked before public launch — it is not legal advice.
