Privacy Policy

Privacy

This page describes what data Sumilca stores, what we receive from Google Sign-In, and how deletion requests are handled.

Data We Store

  • Search conditions (destination, commute/schooling preferences, weights).
  • Saved ranking summaries (scores, notes, ordering).
  • Favorites and hidden property settings needed to restore your view.

We limit stored data to what is necessary for comparison and product operation.

Google Sign-In Data

Our Google OAuth scope is limited to basic account information:

  • Google user identifier
  • Display name
  • Email address
  • Profile image URL

This information is used only for authentication and account display, not for ad targeting.

Third-party services

We use Google (Google OAuth) for sign-in, and the contact form is relayed via Web3Forms, so the email and message you submit pass through that service. We do not sell personal data or share it for advertising.

Retention and Deletion

  • Session/cookie data is retained for up to 30 days and then expires automatically.
  • Deletion requests are handled within 7 business days after receipt.
  • Where legally required, certain records may be retained for a longer period.

You can request account and data deletion from the in-app settings or by contacting support.
